Closes #6605 New Forms show editable feedback while Resource actions run. The `formProgress` variable starts with `status: "idle"`, `loaded: 0`, `total: 0`, and `files: []`. It becomes pending during submission, then returns to idle. The existing `formState` still reports only initial, success, or error. The Progress container says “Submitting…” and adds measured whole-request bytes when the total is known. Files include ID, field name, name, size, and type. The browser cannot measure reliable per-file transfer bytes in the single multipart request. The binding editor suggests one example file to reveal those fields; the example never enters the actual Form value. Saved Forms retain their existing bindings and submission message. ## Checklist - [x] Keep the existing Form outcome variable and add upload activity, byte counts, and file details. - [x] Show zero byte defaults on insertion, new submissions, cancellation, and Preview reset without fake runtime files. - [x] Suggest file fields in Form and Resource bindings while evaluation, reset, rendering, and stored values use real data. - [x] Preserve Builder Preview headers, authentication, response checks, and cancellation. - [x] Keep existing success/error feedback and saved-Form fallback. - [x] Reset external progress when an active published Form unmounts. - [x] Update Form, Variables, and MCP/CLI guides; clarify the older screenshot and final-only simulation. Generated MCP docs check passes. - [x] Audit Form and Variables docs against final progress behavior; clarify the older Variables screenshot. - [x] Cover lifecycle, transport, repeated submission, cancellation, unmount, Preview, template, MCP binding/style, and editor completion with focused tests. - [x] Run relevant typechecks, lint, formatting, fixture generation, and independent review. - [x] Required CI checks pass on the latest commit. ## Verification Local focused Form browser tests (25), Form template tests (12), Builder Preview and Form context tests (14), and mounted editor example/reset tests (6) pass. Builder, SDK React, SDK registry, and project-build typechecks pass, as do lint, formatting, and fixture generation. The fixture sync regenerated two unrelated linked-project site paths; those outputs were restored before commit. Independent review found no remaining issues. All latest-commit checks passed; E2E shard 9 passed on a targeted rerun after its two Form tests also passed locally with 11 related tests. This follow-up adds 162 net non-test lines, more than the initial estimate. The extra code identifies the actual callback-bound variable by ID, even when renamed, and gives autocomplete a separate example scope so it cannot affect actual values. One provider covers Form fields and Resource editors. No schema or package was added. The existing Variables screenshot predates `formProgress`; its explanatory text is current. The React Router fixture's built browser client grew by 4 KiB on Linux CI (376 → 380 KiB), and its checked limit matches that measured output. Multipart transfer remains one whole request. Browser submission supplies live progress. MCP can discover `formProgress`, bind the Progress container, and style it; server simulation reports final outcomes and does not measure browser uploads.
Builder E2E tests
Builder E2E workflows run with Playwright Test. The Playwright setup project waits for PostgREST, resets the disposable database, and warms the login route before Chromium runs the selected tests.
Run the suite
Use the full command for CI-like validation:
pnpm e2e:builder
The first run after migrations change applies the regular migration pipeline
and writes an ignored schema cache under .cache/builder-e2e. Refresh it
explicitly with:
pnpm e2e:builder:refresh-schema-cache
The regular E2E suite uses lightweight PostgreSQL containers. Verify that the complete migration chain also applies to the pinned Supabase PostgreSQL image with:
pnpm e2e:builder:check-supabase-migrations
Pass normal Playwright Test arguments after --. For example:
pnpm e2e:builder -- --grep "Builder can copy, duplicate, and delete a page"
pnpm e2e:builder -- 'apps/builder/e2e/tests/pages-actions.[shard-3].e2e.ts'
pnpm e2e:builder -- --debug --grep "Builder can copy"
A lightweight Playwright discovery pass validates the selection before Docker, database migrations, browser installation, or the Builder build starts. A filter that matches no tests therefore fails without starting the test environment.
Fast local reruns
Keep the E2E backend and Builder development server running to avoid rebuilding Builder and restarting Docker for each edit.
Terminal 1:
pnpm e2e:builder:dev:backend
Terminal 2:
pnpm dev
Terminal 3:
pnpm e2e:builder:dev -- --grep "Builder can copy, duplicate, and delete a page"
pnpm e2e:builder:dev defaults to
E2E_BUILDER_URL=https://127.0.0.1:3000. Override it when the development
server uses another port. Chromium maps wstd.dev and its project subdomains
to loopback for local Builder URLs, so host-file changes are unnecessary.
The development backend uses E2E_DB_BOOTSTRAP=if-empty and keeps Docker
containers running. The Playwright setup project still resets test data before
each invocation.
Test organization
- Put workflows in
e2e/tests/*.e2e.tsand importtestfrome2e/test.ts. - Use Playwright's
pagefixture for the workflow under test. Playwright gives each test an isolated context and closes it automatically. - Use Playwright's
contextfixture when setup should share authentication with the workflow page. - Use
withBrowserContext(browser, callback)for isolated setup or setup that runs inbeforeAll. If cookies must survive frombeforeAllinto the tests, create an explicit context withnewBrowserContext(browser)and close it inafterAll. - Use
newIsolatedPage(browser)for identities that must not share cookies. - Keep tests in a file independent even though Playwright runs them in declaration order by default.
CI discovers isolated Playwright shards from filename tags. Each shard uses four workers, and files are assigned by measured CI duration to keep jobs near three to four minutes:
pages-actions.[shard-3].e2e.ts
Every E2E filename must contain at least one unique shard tag. CI derives its matrix from those tags, so adding or removing a shard does not require editing the workflow. Files with multiple tags are partitioned across those shards. All files selected by a shard must use the same set of tags. Rebalance by changing filename tags when measured job durations drift. Suites may opt into parallel mode only when every worker creates uniquely named setup data and the tests do not depend on each other's mutations.
Backend organization
Development, E2E, schema-cache, and Supabase compatibility commands share the
backend definition in apps/builder/backend. compose.yaml defines the common
services, and compose.<mode>.yaml defines only the differences for a named
mode. Backend commands resolve these files by convention; callers do not pass
Compose filenames.
The schema-cache fingerprint discovers migration sources and non-test backend files automatically. Adding a database image, initialization script, Compose override, or migration therefore invalidates the cache without updating a filename registry.
Failures
Failed shard jobs upload the Playwright HTML report, traces, screenshots, videos, and backend service logs.
When you need a completely clean backend locally:
