## Summary
This improves how agents discover, author, inspect, and verify Webstudio
projects while reducing unnecessary MCP context usage.
## What changed
- Adds an **Agents** section to Project Settings with ready-to-run setup
commands and client configuration for Claude Code, Codex, Cursor, and VS
Code.
- Makes large list and schema responses compact and paginated by
default, with **verbose** available when complete records or diagnostics
are needed.
- Applies consistent compact output to assets, instances, styles, design
tokens, CLI schemas, and project-session metadata.
- Returns actionable expression warnings for props, resources, and
Collection bindings, including unknown variables and risky render-time
mutation resources.
- Improves Collection expression guidance so agents can bind array items
with the correct scoped variables.
- Reports rendered audit outcomes explicitly as complete, partial,
confirmation-required, or failed.
- Expands runtime output schemas so MCP clients can validate responses
reliably.
- Strengthens the packaged CLI smoke workflow with a realistic
seven-page stdio MCP scenario.
## Architecture
- Consolidates `project-build` from 65 file-oriented entrypoints to 11
architecture-owned surfaces.
- Separates the core model, contracts, runtime authoring, transfer,
state, project sessions, MCP, visual tooling, persistence codecs, and
authenticated server services.
- Isolates Node-only JSX evaluation from browser-safe transfer utilities
and authenticated server modules.
- Keeps persistence codecs independent from authenticated database
services, preventing unrelated module initialization.
- Defines shared instance-path types once and reuses them across runtime
modules.
- Preserves Immer initialization through explicit package side-effect
metadata.
- Adds package tests that prevent a return to source-file entrypoints or
generic exposure of Node-only surfaces.
## Validation
- Full repository checks, tests, typechecks, generated-file checks, and
fixtures
- All 163 Builder test files and 2,141 tests
- All 71 project-build test files and 1,794 tests
- Lint and package-boundary validation
- Full packed CLI release smoke test, including install, preview, agent
setup, seven-page stdio MCP workflow, rendered audit, and structured
commands
## What changed\n\n- Define concrete output schemas for every public
runtime operation.\n- Expose output schemas through generated runtime
contracts and MCP tool discovery.\n- Validate runtime results against
their declared schemas, including mutation result envelopes.\n- Add
output contracts for project-session status, refresh, reset, Collection
insertion, and generated-preview tools.\n- Make every advertised MCP
output schema explicitly object-shaped for strict clients.\n- Keep
generated schema definitions at the correct root so local references
resolve during tool discovery.\n- Report the correct session operation
metadata for refresh and reset.\n- Preserve local workspace package
resolution when the local CLI builds a generated React Router
preview.\n\n## Why\n\nAgents could discover input requirements, but
several tools did not describe their returned data. Strict MCP clients
could also reject the complete tool catalog during reconnect because
output schemas were not consistently object-shaped or contained
unresolved local references.\n\n## User impact\n\n- Agents can plan
calls from complete input and output contracts.\n- MCP clients can fetch
the full Webstudio tool catalog without schema-validation failures.\n-
Agents can reliably parse and validate command results.\n- Local
generated previews continue to work for visual verification.\n\n##
Validation\n\n- Every public runtime operation has an output schema.\n-
Every advertised MCP output schema is object-shaped and has resolvable
local references.\n- A real stdio MCP client connected through the local
CLI and fetched 154 tools, including 119 valid output schemas.\n-
Runtime output contracts validate representative query and mutation
results.\n- A fresh subagent refreshed a real project session, built and
started the generated site, captured the target route with HTTP 200,
checked preview status, and stopped the server.\n- Focused project-build
tests, project-build and CLI typechecks, lint, formatting, and
generated-doc checks passed.\n
## What changed
- Return structured validation issues with stable codes, complete field
paths, constraints, and minimal correction examples.
- Preserve validation details through the Builder API, CLI, MCP, local
project sessions, and tRPC errors.
- Explain invalid expressions, JSX fragments, page selectors, component
inputs, asset updates, and project settings in terms an agent can act
on.
- Remove stack frames and credentials from parser details before
exposing them.
- Keep concise human-readable errors while making the complete
structured issues available to agents.
## Why
Agents previously received vague errors without enough information to
repair a request. They could repeat the same invalid call or require
manual intervention.
## User impact
CLI and MCP agents can now identify the exact invalid field, understand
the constraint, see a valid example, and retry with a corrected request.
## Validation
- Focused runtime, MCP, CLI, API, and tRPC validation tests.
- Structured error propagation tests across local and server execution.
- Typechecks and generated contract verification.
## What changed
- Add an `insert-collection` MCP and CLI operation for creating repeated
UI from array or object data.
- Create the Collection, iterable binding, current-item/current-key
parameters, repeated item structure, and descendant bindings atomically.
- Accept literal JSON data or expressions backed by project variables
and resource results.
- Support `collectionItem` and `collectionItemKey` expressions inside
the repeated Webstudio JSX item.
- Return the created Collection, item root, and parameter IDs for
immediate inspection and follow-up edits.
- Document when agents should use Collection for lists, grids, cards,
rows, options, tabs, and other repeated content.
## Why
Building a data-driven list previously required several low-level
operations and manual handling of Collection's internal parameters. A
missed step could leave a partially configured or incorrectly scoped
Collection.
## User impact
Agents can turn resource or variable data into a correctly bound
repeated layout in one operation, then inspect and refine the result
normally.
## Validation
- Real-world local CLI test created and rendered a three-product
Collection from project data.
- Tests cover literal arrays, objects, resource expressions, item/key
bindings, malformed fragments, ID conflicts, server execution, and
project-session behavior.
- 176 focused tests, project-build typecheck, and generated-doc checks
pass after rebasing onto current `main`.
Fixes three MCP issues that could cause misleading mutation results,
unstable instance ordering, and project settings that disappeared after
refresh.
## Changes
- Prevents committed mutations from returning `PROJECT_SESSION_BUSY`.
- Ensures retrying after a reported failure cannot silently create
duplicate instances.
- Reconciles the local project session after a mutation commits
remotely.
- Adds deterministic append behavior with `position: "end"`.
- Preserves the requested order when moving multiple instances.
- Makes project settings updates persist across refreshes.
- Reports no-op project settings updates accurately.
- Updates MCP documentation and generated contracts for the new
behavior.
## Verification
- Reproduced and retested all three user reports with a subagent against
a real local project.
- Verified overlapping duplicate operations commit exactly once.
- Verified ordered moves remain correct after refresh.
- Verified project settings survive refresh.
- Passed all project-build tests: 1,745 tests.
- Passed all CLI tests: 720 tests.
- Passed type checks and lint.
This update helps AI agents understand, audit, and visually verify
Webstudio projects more reliably. It also adds clearer guidance for
expressions, Collections, screenshots, and responsive rendered audits.
### Audit complete projects
- Run one `audit` command across accessibility, SEO, security, assets,
styles, and performance.
- Audit the whole project or focus on a specific page, scope, or
severity.
- Receive stable findings with locations, explanations, and recommended
fixes.
- Continue large result sets through pagination without repeating
general guidance.
### Audit the rendered website
- Build and inspect the generated website, rather than relying only on
stored project data.
- Check every static page at representative mobile, tablet, and desktop
widths.
- Use one suitable viewport inside each configured breakpoint range.
- Reuse the same browser and resize pages between captures for
substantially faster audits.
- Process multiple pages concurrently while keeping resource use
bounded.
- Supply concrete examples for dynamic routes such as blog posts.
- Review and confirm unusually large screenshot plans before they run.
### Find visual and performance problems
Rendered audits can detect:
- Horizontal page overflow.
- Broken images.
- Images loaded eagerly below the fold.
- Images that are much larger than their rendered size.
- Render-blocking resources.
- Legacy font formats.
- Pages that fail to load or redirect somewhere unexpected.
- Pages captured before their layout becomes stable.
Detailed screenshots, measurements, failures, and timing evidence are
saved locally for further inspection.
### Capture generated pages directly
- Capture a project route with `webstudio screenshot --path /route`.
- Automatically generate and start a temporary production-style preview.
- Stop the temporary preview after the screenshot is captured.
- Return navigation, responsive layout, and page-size evidence with JSON
output.
- Allow external image domains needed by the generated preview.
### Reuse generated previews
- Cache generated preview builds when the project has not changed.
- Reuse preview dependencies across regenerations.
- Keep preview dependencies isolated from the user’s project
dependencies.
- Surface preview build and startup failures with useful diagnostic
output.
- Include local project assets in generated previews.
### Author Collections correctly
- Explain when Collection is required for arrays and objects.
- Guide agents to bind the complete iterable instead of one item or the
response wrapper.
- Explain how Collection repeats its children for every entry.
- Explain current-item and current-key scope.
- Preserve Webstudio’s generated Collection parameters.
- Guide agents to use stable values for repeated interactive components.
### Write expressions with fewer mistakes
- Add a dedicated `webstudio://project/expressions` reference.
- Document expression scope, supported syntax, and supported methods.
- Explain how resources, variables, Collections, actions, and `system`
values are accessed.
- Distinguish fixed values from runtime expressions.
- Provide valid examples for text, props, resource URLs, headers, query
parameters, and bodies.
- Warn agents that valid syntax does not guarantee that runtime data has
the expected shape.
### Improve agent discovery
- Make Collection and expression workflows discoverable through
`meta.guide`.
- Return Collection-specific instructions through `components.get`.
- Point relevant command schemas to the expression reference.
- Keep detailed guidance available without placing it in every tool
response.
### Improve audit reliability
- Report which rendered captures passed, found issues, failed, or were
skipped.
- Distinguish planning, preview, capture, and cleanup failures.
- Include actionable retry instructions with rendered failures.
- Preserve completed evidence when part of an audit fails.
- Detect stale or conflicting preview servers more clearly.
- Support cancellation and bounded capture timeouts.
### Improve packaged CLI verification
- Add a release-shaped CLI smoke test.
- Install the packed CLI in an isolated temporary project.
- Fail on peer-dependency warning floods.
- Verify preview, screenshots, MCP calls, rendered audits, and generated
assets.
- Confirm that generic React Router previews do not include Docker-only
image dependencies.
- Keep CLI and MCP stdout machine-readable while progress remains on
stderr.
## User Impact
Agents can now audit a real rendered Webstudio site, inspect responsive
behavior, find concrete visual and performance problems, and provide
evidence for their conclusions. They also receive much clearer
instructions when turning API data into repeated content or writing
dynamic expressions.
Improves CLI and MCP reliability across project synchronization, asset
editing, imports, audits, and clipboard workflows.
## Changes
- Keeps asset filename and description updates after session refresh.
- Prevents intermittent Immer patch errors during consecutive MCP
mutations.
- Prevents false edit conflicts caused by stale local session state.
- Preserves asset uploads without treating them as redundant metadata
updates.
- Exposes editable asset filenames consistently through MCP.
- Imports project assets correctly when copying projects between
environments.
- Supports refreshing partially available project snapshots.
- Keeps MCP operations working when optional project data is
unavailable.
- Produces clearer compatibility errors when the API and CLI versions
differ.
- Makes rendered audits more resilient when individual screenshots fail.
- Prevents rendered audits from hanging while starting browser captures.
- Handles denied clipboard permissions without uncaught browser errors.
- Improves copy and paste reliability for pages, components, styles, and
animations.
## Verification
- Asset uploader tests and typechecking pass.
- Focused asset workflow E2E passes.
- Complete E2E shard 1 passes.
- Realistic MCP subagent test confirms:
- Asset filename and description persist after refresh.
- Consecutive mutations work without manual refresh.
- No Immer patch error occurs.
- No false conflict occurs.
- Original asset values can be restored successfully.
## Summary
This update adds new MCP and CLI capabilities for project auditing,
structured data, project-specific agent instructions, focused project
search, safer bulk editing, image descriptions, font discovery, visual
verification, and external registry inspection.
## New Capabilities
### Audit projects
- Run a single `audit` command across accessibility, SEO, security,
assets, styles, and performance.
- Limit an audit to selected scopes, pages, or severity levels.
- Receive stable findings with locations and suggested fixes.
- Run rendered audits across desktop, mobile, and Builder breakpoint
widths.
- Detect horizontal overflow, broken images, oversized images, eager
below-fold images, render-blocking resources, and legacy font formats.
- Identify unused assets, tokens, CSS variables, local styles, and
breakpoints.
- Identify duplicate token declarations.
- Detect accessibility issues involving names, labels, headings,
landmarks, IDs, keyboard focus, ARIA, iframes, and autoplaying media.
- Detect SEO issues involving titles, descriptions, language, social
images, and structured data.
- Detect unsafe new-tab links and write resources exposed during page
rendering.
### Search an entire project
- Search project text, labels, props, resources, assets, and styles
through `search-project`.
- Find relevant records without downloading and reparsing the full
project snapshot.
- Scope searches to the relevant project-data areas.
### Add validated JSON-LD
- Add structured data with a dedicated JSON-LD component.
- Place JSON-LD inside the page Head Slot.
- Edit JSON in a purpose-built code editor.
- Prevent structurally invalid JSON-LD from being saved.
- Validate Schema.org types, properties, and values.
- Find invalid, missing, unknown, deprecated, or incompatible structured
data through the SEO audit.
- Let agents discover the correct JSON-LD workflow without using page
custom metadata or a generic HTML embed.
### Configure project-specific agent instructions
- Add AI-agent instructions from the new **Agents** section in Project
Settings.
- Synchronize those instructions into a managed root `AGENTS.md`.
- Update or remove the managed file automatically during project sync.
- Protect existing user-owned `AGENTS.md` files from being overwritten.
- Share the instructions with authenticated CLI and MCP agents.
- Keep agent instructions out of publicly readable production bundles.
### Generate and manage image descriptions
- Audit image assets for missing descriptions.
- Let a vision-capable agent inspect each image in its rendered context.
- Save generated descriptions to multiple image assets in one operation.
- Mark images as intentionally decorative.
- Reuse the saved asset description wherever the image is used.
- Re-run the audit to verify that missing-description findings are
resolved.
### Perform bounded bulk replacements
- Replace matching literal text across selected pages with
`replace-text`.
- Replace matching fixed prop text with `replace-prop-text`.
- Replace matching resource names or URLs with `replace-resource-text`.
- Restrict replacements by page, instance, prop, resource, field, match
mode, and maximum change count.
- Leave dynamic expressions unchanged.
### Inspect element ancestry
- Return an element’s direct parent in instance listings.
- Request the complete ancestor chain when inspecting an element.
- Understand tree placement without rebuilding the instance hierarchy
from raw project data.
### Discover available fonts
- List uploaded font families through `list-fonts`.
- Discover available system font stacks.
- Inspect font family, style, weight, format, and associated asset
information before applying typography.
### Inspect external component registries
- Inspect a local or remote shadcn-style registry item.
- Read its description, files, dependencies, targets, and documentation.
- Receive an explicit Webstudio compatibility report.
- Inspect registry metadata without installing or executing external
code.
### Capture generated project routes directly
- Run `webstudio screenshot --path /route` against the configured
project.
- Generate a temporary production-style preview automatically.
- Capture the requested route.
- Stop the temporary preview after capture.
- Avoid manually building and starting a preview for a single
screenshot.
### Assert visual changes
- Add expected text to screenshot comparisons.
- Set maximum pixel mismatch limits.
- Set minimum or maximum changed-region counts.
- Assert whether overall brightness or a color channel moved in the
expected direction.
- Use these assertions as pass/fail evidence for visual changes.
### Require compatible CLI versions
- Send the project-bundle contract version with CLI synchronization
requests.
- Stop incompatible CLI versions before they receive incomplete project
data.
- Tell users exactly how to update the CLI or run the latest version
once.
- Prevent older clients from silently dropping project settings.
## Upgrade Note
This branch introduces a new synchronized project-bundle contract. Older
CLI versions must update before synchronizing against the new API.
```sh
npm install -g webstudio@latest
```
Or run the latest version once:
```sh
npx webstudio@latest <command>
```

## prettier -> oxfmt (0.58.0)
- .oxfmtrc.json generated with `oxfmt --migrate=prettier`: trailingComma
es5, printWidth 80 (oxfmt defaults to 100), sortPackageJson disabled,
.prettierignore patterns folded in (file deleted).
- ignorePatterns additionally exclude yml/yaml/toml/jsonc and
packages/cli/templates/** so oxfmt covers exactly the file set prettier
used to format (ts,tsx,js,json,css,md) and never touches user-facing
scaffolding artifacts.
- root `format` script, nano-staged pre-commit hook and the CI check
(`pnpm oxfmt --check`, replacing `prettier --cache --check` and its
actions/cache step — oxfmt checks the whole repo in ~0.7s) now run
oxfmt.
- every generator script that ran `prettier --write` on __generated__
output now runs `oxfmt` (css-data, icons, html-data, postgrest, sdk,
sdk-components-*, apps/builder tailwind preflight).
- the four scripts that used prettier's JS `format()` API write raw
source instead and their package.json scripts pipe the generated file
through the oxfmt CLI: project-build generate-docs +
generate-runtime-operation-contracts, cli generate-docs, apps/builder
generate-server-only-api-metadata. oxfmt rejects paths containing "..",
so cross-package generated files are formatted via a subshell cd into
the owning package.
- one-time reformat: oxfmt's canonical output differs from prettier on 8
repo source files (binary-operator continuation indent, import() call
wrapping, sub-pixel spacing of empty for-clauses); oxfmt honors existing
`// prettier-ignore` comments so intentional layouts are kept.
- prettier remains ONLY as a cli devDependency for the
prettier/standalone HTML normalizer inside html-to-jsx.test.ts, and
inside fixtures/ + packages/cli/templates/ (ships to scaffolded user
projects; out of scope here).
- editor config switched from esbenp.prettier-vscode to oxc.oxc-vscode
(devcontainer extension list, .vscode editor.defaultFormatter).
## oxlint 1.56 -> 1.73
- oxlint 1.73 rules-of-hooks special-cases hooks NAMED useEffectEvent:
their results may only be called from effects. Our
app/shared/hook-utils/effect-event.ts is a stable-callback helper
(useEvent pattern), intentionally called from event handlers and passed
as props. The rule is disabled via .oxlintrc.json overrides for the five
files doing this (product code untouched); note those files lose
hook-order linting entirely until the rule becomes configurable.
## TypeScript 5.8.2 -> 7.0.2 (native compiler)
- `tsc` is now the Go-based native binary; all `tsgo` script usages
(workspace packages and fixtures) renamed back to `tsc` and
@typescript/native-preview removed (the package is being phased out).
- fixes for TS7 changed defaults and stricter checks:
- `types` now defaults to [] -> base tsconfig sets "types": ["node"]
(restores the implicit-@types/node behavior of TS5).
- `rootDir` now defaults to ./ -> every tsconfig.dts.json sets
"rootDir": "./src" (TS5011 otherwise).
- import assertions removed -> cli/src/cli.ts uses `with { type: "json"
}` (TS2880).
- stricter isolatedDeclarations inference -> explicit annotations in
css-data bin/property-filter.ts (TS9010) and image image-dev.stories.tsx
(TS9013).
- declaration serialization limit -> project-build builder-runtime.ts
runtimeOperationContracts gets an explicit type (TS7056); the annotation
preserves the narrow RuntimeOperationId union.
- TS7 ships no stable programmatic API:
- react-sdk (component-generator tests drive the compiler API) aliases
its typescript devDependency to @typescript/typescript6@^6.0.2; its bin
is `tsc6`, so the package's typecheck still runs native TS7 tsc from the
workspace root.
- generate-arg-types keeps typescript 5.8.2 for react-docgen-typescript.
- fixtures/ and packages/cli/templates/ keep typescript 5.8.2
(user-facing); fixture scripts still work because plain `tsc` resolves
to their local dependency.
## vite -> rolldown-vite 7.3.1 (oxc bundler)
- global pnpm override `"vite": "npm:rolldown-vite@^7.3.1"`: the builder
app (remix v2 vite plugin works unmodified), every package vite build
and the storybook build now bundle on rolldown/oxc.
- vitest is scoped BACK to vanilla vite via `vitest>vite`,
`vite-node>vite` and `@vitest/mocker>vite` overrides because vitest
3.1's runner does not understand rolldown's SSR transform
(__vite_ssr_exportName__ ReferenceError in every suite).
- those overrides pin vite EXACTLY to 6.3.4: letting ^6.3.4 float to
6.4.3 breaks cli prebuild tests (dynamic import of a generated
app/routes/$.tsx fails to resolve under 6.4.3's loader).
## unrelated cleanup requested during review
- apps/builder commands.ts imports duplicate-tokens-group statically
instead of via dynamic import. The circular dependency the dynamic
import guarded against only exists through the command-panel barrel
(command-panel.tsx > groups/index.ts > commands-group.tsx >
commands.ts); importing the group module directly is cycle-free
(verified with madge), matching the neighboring wrap-group and
convert-group imports.
## verification
- pnpm lint, oxfmt --check: clean.
- pnpm -r typecheck (TS7 native) and pnpm dts: clean.
- pnpm -r test: all suites pass (builder 2093 tests, cli 630, react-sdk
45, project-build 11, ...).
- builder app build, full workspace build, cli build and storybook build
all succeed on rolldown-vite.

- Fix publish sync for empty JSON data variables
- Retry transient asset downloads once with shared sync-client backoff
- Fix Builder paste handling for Webstudio transfer data
- Add transfer/data-envelope terminology and colocated runtime
data-format modules
- Rename page clipboard runtime operation to page transfer semantics
- Report malformed Webstudio/Webflow paste data through paste results
instead of inserting it as text
- Add browser-level E2E coverage for instance, page, folder, template,
generic plugin, malformed data, native input, and content-mode paste
flows
## Details
- Allows empty JSON data variables to sync/publish correctly.
- Adds asset download retry coverage and uses shared backoff logic.
- Introduces runtime `data-formats` modules for data envelopes, instance
transfer data, and page transfer data.
- Removes stale clipboard aliases and `validateTemplateStructure`.
- Keeps clipboard as a Builder UI transport concern while
runtime/protocol use transfer-data terminology.
- Changes paste plugins to return expressive success/error results so
callers can show toast errors and stop fallback insertion.
- Prevents malformed Webstudio transfer payloads from falling through to
text/HTML/markdown insertion.
- Handles malformed Webflow-owned paste data without throwing.
- Adds shared copy-paste fragment insertion helpers to reduce duplicated
breakpoint-warning/fragment-data logic.
This PR expands Webstudio MCP and CLI into a more complete agent
authoring interface. Agents can discover project capabilities, edit real
Webstudio content, use data/resources, verify visual output, and report
useful issues when workflows fail.

1. fix the issue with expressions requiring string when expression, this
is an issue not only for meta in page settings but for any field that
supports bindings
2. make sure llm knows when to use bindings and when to just set the
string value, test it with a subagent without additional context
## Summary
- Add CLI project import support from synced `.webstudio/data.json` into
another project via a destination share link.
- Move project bundle import/export contract into
`@webstudio-is/protocol`, including bundle versioning, staged upload
constants, schema validation, and fixture coverage.
- Upload project bundle data through staged TUS upload before calling
the import RPC to avoid request body limits.
- Upload referenced assets as binary files through the existing asset
upload route before importing asset rows.
- Add `--skip-assets` and `--ignore-version-check` import options.
- Add retry handling for transient missing imported asset files by
re-uploading only the reported missing assets.
- Share missing-asset import error formatting/parsing through protocol
to avoid duplicated string contracts.
- Preserve browser asset upload behavior while adding API upload
support.
- Normalize schema naming across the branch to lower-case names without
`Schema` suffix.
User reported:
The repeated animation issue has been fixed on Webstudio Cloud hosting,
but the bug still exists — and is actually even worse — on self-hosted
deployments, whether it's on Netlify or Vercel.
Animations sometimes play twice on the initial page load. They also
replay before navigating to another page and when clicking an anchor
link that points to a section on the same page.
Additionally, on the very first visit to the website, the first
interaction with Radix components causes all animations to replay again.
As far as I can tell, this no longer happens after assets are cached,
but the initial glitch is still noticeable and doesn't look very
polished from a user experience perspective.
Closes https://github.com/webstudio-is/webstudio/issues/2966
## Description
Fixes visitor-facing crashes when a text binding resolves to a non-text
value, such as an object returned from a resource.
Generated expression children now render through `renderText`, which
preserves strings and numbers and renders other runtime values as empty
text. This prevents React SSR from throwing `Objects are not valid as a
React child` when resource data shape changes unexpectedly.
## Changes
- Added `renderText(value)` runtime helper.
- Wrapped generated expression children with `renderText(...)`.
- Updated generated page imports to include `renderText`.
- Added rendering tests for resource status/error fields and
object-shaped bindings.
## Tests
```bash
pnpm --filter @webstudio-is/react-sdk test -- context.test.tsx component-generator.test.tsx
pnpm --filter @webstudio-is/react-sdk typecheck
pnpm --filter ./packages/cli typecheck
**Description**
Prevents published pages from rerendering the outgoing generated page
during pending internal navigation.
React Router can rerender the current route while the next route loader
is pending. The generated `Page` was rendered directly inside that
route, so the entire outgoing page could rerender before the next page
appeared.
This adds a memoized `PageBoundary` keyed by `url`, so the generated
page only rerenders/remounts when the actual page URL changes. The SDK
context value is memoized by `resources`, preserving same-URL resource
updates without exposing the full page tree to unrelated
pending-navigation rerenders.
**Changes**
- Added `PageBoundary` to React Router and Remix/default HTML route
templates.
- Kept `key={url}` behavior for HTML Embed script reloads on dynamic
pages.
- Added regression tests for:
- no outgoing page rerender while destination navigation is pending
- same-URL resource changes still update generated page content
- Added Vitest setup for `sdk-components-react-router`.
**Verification**
```txt
pnpm --filter @webstudio-is/sdk-components-react-router test src/link.test.tsx
pnpm --filter @webstudio-is/sdk-components-react-router typecheck
pnpm --filter @webstudio-is/sdk-cli typecheck
```
## Description
Adds support for plain text pages. Related to
https://github.com/webstudio-is/webstudio/issues/4257
This PR introduces `text` as a supported document type, stores plain
text page content in page metadata, and generates `text/plain` route
handlers for Remix and React Router templates.
It also limits HTML-specific Builder actions on text pages, excludes
XML/text pages from the generated static sitemap, and adds SDK coverage
for text document schema and sitemap behavior.
## Steps for reproduction
1. Create or edit a page in Builder.
2. Set the document type to `TEXT`.
3. Enter plain text content in page settings.
4. Build with a Remix or React Router template.
5. Open the generated text page URL, for example `/robots.txt`.
6. Expect the response body to contain the configured text content with
`Content-Type: text/plain; charset=utf-8`.
7. In Builder, expect HTML insert/wrap/convert/tag actions to be
unavailable for text pages.

Closes https://github.com/webstudio-is/webstudio/issues/3991
Adds HTTP Basic Authentication support for published pages and
project-level `.wsauth` rules.
This introduces a new `@webstudio-is/wsauth` package that owns the
generic authentication format logic: parsing, validation, serialization,
route matching, resource generation, and request authentication. The
current supported method is `basic`, with the package structured so
additional auth methods can be added later.
Builder changes include:
- Page Settings now has an `Authentication` section for per-page Basic
Auth credentials.
- Project Settings now has an `Authentication` section for editing
`.wsauth` route rules.
- Page Settings was split into section-specific files with focused
tests.
- Auth UI shows Pro badges/info tooltips but remains editable.
- Publishing to custom domains is blocked on plans without `allowAuth`
when either page auth or project auth is configured.
- ProBadge now renders as a real pricing link and uses improved text
alignment.
Build/publish changes include:
- CLI prebuild generates and merges `.wsauth` entries.
- Published app templates enforce auth for HTML/XML routes.
- Generated auth resources are shared between build output and runtime.

Redirects are supported in vike but never worked when SSG is generated
and actually failed the build. Extended ssg fixture with redirect to
catch this on CI.

1. **Title and meta tags (specified in page settings) are no longer
removed when page is loaded.** For this I switched to the same
components we use in cloud template.
2. **Avoid duplicating custom code**. Both server and client rendered
the same custom code and react instead of hydrating just duplicates
them. To fix this I removed custom code from client side so all scripts
and styles are rendered only once.
3. **Removed origin from og:image url.** Turns out it is not necessary
to have full url for og:image to work, all services are capable to
resolve url. We can remove it at least for static websites.
4. **SSG rendered fake url (https://url) in ld-json** which can have
unexpected results in search engines. Removed it, google should be able
to provide necessary url by itself.

## Problem
The current-date system resource works in the Webstudio builder but
fails in published sites with "dateTime attribute is not set" errors.
## Root Cause
The CLI templates' `customFetch` functions handle the `sitemap.xml`
local resource but don't handle the `current-date` resource, causing
fetch requests to fail when sites are published.
## Solution
Added `current-date` handler to all CLI template `customFetch`
functions, following the same pattern as the existing `sitemap.xml`
handler.
## Changes
- Add current-date handler to Remix HTML/XML templates
- Add current-date handler to React Router HTML/XML templates
- Add customFetch with current-date handler to SSG template
- Normalize dates to midnight UTC to prevent hydration mismatches
## Testing
The fix ensures that when the Time component uses `system.currentDate`,
it will work correctly in published sites, not just in the builder.
Closes https://github.com/webstudio-is/webstudio/issues/3510
## Summary
This PR adds a **Current Date** system resource, extends the `system`
object with a `pathname` property, and enhances the **Time component**
with custom date formatting capabilities to provide more flexibility and
prevent hydration errors.
### Key Features
1. **Current Date System Resource** - Provides normalized date/time
information that prevents React hydration errors
2. **System Pathname** - Adds `pathname` property directly to the
`system` object for easy access in expressions
3. **Time Component Custom Formatting** - Adds a `format` prop with
template tokens for flexible date/time display
## Motivation
These changes solve important use cases:
- **Current Date**: Prevents React hydration errors when displaying
dynamic dates (e.g., copyright years in footers). Previously, using `new
Date()` in expressions would cause server/client mismatch.
- **System Pathname**: Provides easy access to the current page path in
expressions without needing to parse the URL manually.
- **Custom Time Formatting**: Allows users to format dates with simple
templates (e.g., `YYYY-MM-DD`) without being limited to
`Intl.DateTimeFormat` options, and provides a simple way to exclude
specific date or time components to avoid hydration issues.
## Changes
### Current Date Resource
- Created
[`apps/builder/app/shared/$resources/current-date.server.ts`](apps/builder/app/shared/$resources/current-date.server.ts)
- Provides date fields: `year`, `month`, `day`, `iso`, `timestamp`
- All values normalized to midnight UTC (00:00:00.000Z) to prevent
hydration errors
- Registered in
[`rest.resources-loader.ts`](apps/builder/app/routes/rest.resources-loader.ts)
- Added to SystemResourceForm dropdown in UI
### System Pathname
- Added `pathname` property to
[`System`](packages/sdk/src/schema/pages.ts) type
- Updated [`system.ts`](apps/builder/app/shared/system.ts) to compute
and include pathname
- Normalized empty pathname to `'/'` for consistency
- Available in expressions as `system.pathname`
### Time Component Enhancements
- Added [`formatDate()`](packages/sdk-components-react/src/time.tsx:353)
function supporting template tokens:
- `YYYY`, `YY` - year (4-digit, 2-digit)
- `MM`, `M` - month (zero-padded, no padding)
- `DD`, `D` - day (zero-padded, no padding)
- `HH`, `H` - hours (zero-padded, no padding)
- `mm`, `m` - minutes (zero-padded, no padding)
- `ss`, `s` - seconds (zero-padded, no padding)
- Added `format` prop to
[`Time`](packages/sdk-components-react/src/time.tsx:386) component that
overrides `dateStyle`/`timeStyle` when provided
- Updated component logic to check for `format` prop first before
falling back to `Intl.DateTimeFormat`
- Added comprehensive tests for date formatting in
[`time.test.ts`](packages/sdk-components-react/src/time.test.ts)
- Updated component metadata in
[`time.ws.ts`](packages/sdk-components-react/src/time.ws.ts) to include
`format` in initialProps
- Example: `format="YYYY-MM-DD HH:mm:ss"` displays as "2025-11-03
18:47:25"
### Template & Fixture Updates
- Updated all CLI templates (defaults, react-router, SSG) to include
`pathname` in system objects
- Updated all fixture files (47 files total) to include `pathname` in
system objects
- All 694 tests passing
- All typecheck passing
## Usage
### Current Date Resource
Users can now add the Current Date resource from the Data Variables
panel:
1. Click + next to Data Variables
2. Select "System Resource"
3. Choose "Current Date" from the dropdown
4. Access in expressions:
- `date.year` - for copyright year
- `date.month` - current month (1-12)
- `date.day` - current day (1-31)
- `date.iso` - ISO 8601 string
- `date.timestamp` - Unix timestamp
### System Pathname
Access the current page path directly:
- `system.pathname` - current page path (e.g., `/about`, `/blog/post-1`)
### Time Component Custom Format
Use the `format` prop for custom date/time display:
```jsx
<Time datetime="2025-11-03T18:47:25Z" format="YYYY-MM-DD" />
// Displays: 2025-11-03
<Time datetime="2025-11-03T18:47:25Z" format="YYYY-MM-DD HH:mm:ss" />
// Displays: 2025-11-03 18:47:25
<Time datetime="2025-11-03T18:47:25Z" format="M/D/YYYY" />
// Displays: 11/3/2025
```
Technical Notes
- Current Date values are normalized to midnight UTC to ensure
consistency throughout the day and prevent hydration mismatches
- The pathname property is computed from the request URL and normalized
to '/' when empty
- Custom format templates in the Time component are processed before
falling back to Intl.DateTimeFormat
- All changes are backward compatible
