## Summary Complete Validate for large projects with linked MDX content, using the same validation API in the dialog and MCP. Publishing continues independently of diagnostics. - Load MDX sources omitted from the embedded artifact and report storage failures with typed diagnostic reasons. - Reuse parsed MDX and template scope indexes; cache source reads in the shared asset loader. - Exclude conservative non-MDX query candidates while retaining explicit invalid references for diagnostics. - Give validation requests a 60-second server execution budget. - Support both server bundles in E2E tests and make OAuth logging initialization repeatable. - Raise the project bundle import limit from 20 to 32 MiB to reproduce the customer project. ## TODO / acceptance checklist - [x] Import and inspect the customer project locally and on staging. - [x] Reproduce missing embedded MDX sources and slow template materialization. - [x] Load omitted MDX sources and discover nested template dependencies. - [x] Report source-read failures using typed reasons rather than matching error messages. - [x] Reuse template scope indexes and remove duplicate source caching. - [x] Route dialog Validate through the same API as MCP, after flushing editor content. - [x] Preserve publishing in parallel with diagnostics, including failed or unfinished checks. - [x] Fix JSON collection files being treated as MDX query candidates. - [x] Preserve explicit invalid file references so they still produce diagnostics. - [x] Fix E2E routing across both generated server bundles and repeated OAuth logging initialization. - [x] Demonstrate the new review regressions fail before the fixes and pass after them. - [x] Run targeted tests, relevant typechecks, lint, formatting, package boundaries, and generated API checks. - [x] Run the full fixture pipeline and production builder build; no generated fixture changes. - [x] Build the exact staging project locally after the final review changes. - [x] Validate the exact staging project through MCP/CLI after the final deployment. - [x] Complete an actual staging publish after the final deployment. - [x] Address PR comments: simplify the stream mock, explain every diagnostic reason, and retain the existing diagnostic code contract. - [x] Review documentation impact; these fixes restore expected behavior and require no user instruction changes. - [x] Finish CI on the final commit, including all six Builder E2E shards. ## Verification Local checks passed: 179 project-build tests, 78 CLI prebuild tests, 8 asset publication tests, 42 server tests, and 9 publish UI/helper tests. The imported staging project also builds successfully. The new explicit-reference regression and repeated-initialization regression both failed before their fixes and passed afterward. A production build serves the login route and dispatches tRPC requests to its separate server bundle. Validation on staging project `b9d23e54-5dbf-45c4-b6d8-bc4cf842a468` completed in 25.3 seconds after deployment and 23.5 seconds after publishing: 92 documents included, 0 omitted, and 0 MDX errors. The [original staging publish job rerun](https://github.com/webstudio-is/webstudio-saas/actions/runs/36647770120/job/109819143695) succeeded end to end with the final artifact, including CLI/Remix builds, worker deployment, and database updates. [CI on commit `01a9d772dc`](https://github.com/webstudio-is/webstudio/actions/runs/36696154831) is green, including all six Builder E2E shards and Windows/Ubuntu fixture checks. The comment follow-ups simplify the publication test mock and document all diagnostic reasons. Production behavior is unchanged. The 8 publication tests, 6 schema tests, package typecheck, formatter, and lint pass. Disabling the source cache makes the simplified regression fail as expected. Final staging validation passed in 27.1 seconds with 92 documents and no omissions or MDX errors. One additional publish attempt hit a database statement timeout during project sync, before the build. A [retry with no code changes succeeded end to end](https://github.com/webstudio-is/webstudio-saas/actions/runs/36647770120/job/109826767589). CI is green on `01a9d772dc`. Ref #3550
Webstudio CLI
The Webstudio CLI helps you to link, sync and build projects from Webstudio Cloud. This README will guide you through the process of setting up a Webstudio project on your local machine and continually sync it with the cloud.
Prerequisites: Installing Node.js
You need Node.js to use the Webstudio CLI. If Node.js is already installed in your system, you can skip ahead to the section on installing the Webstudio CLI.
To install Node.js using NVM, first install NVM by running:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
Once NVM is installed, you can install Node.js version 22 by running:
nvm install 22
Verify your Node.js installation by checking its version:
node --version
Installing the Webstudio CLI
To get started with the Webstudio CLI:
-
Download and install the CLI using the following command:
npm install -g webstudio@latest -
Confirm the installation by checking the CLI version:
webstudio --version -
To keep your CLI updated, use the same command used for installation whenever a new release is available.
Initiating a Webstudio Project
Now, you can run a Webstudio project on your local machine using this command:
webstudio
This will initiate the flow to connect your Webstudio Cloud project and build it in your local computer. The default flow will guide you through the steps. You can also perform all the operations individually using independent commands.
Commands
Here is the list of independent commands:
- version
- help
- link
- sync
- build
link
The link command stores access to a Webstudio Cloud project. MCP clients use that connection to read and edit the latest Builder build directly; the project does not need to be published or synchronized first.
Shell-capable agents can call MCP tools directly as CLI subcommands immediately after linking. This does not require MCP client configuration or a client restart:
webstudio meta.index
webstudio components.search '{"brief":"button"}'
webstudio insert-fragment --input-file .temp/insert-fragment.json --dry-run
.temp/insert-fragment.json:
{
"parentInstanceId": "<parent-id>",
"fragment": "<section />"
}
The explicit equivalent is webstudio mcp single-op-call <tool> '<json>'.
Use webstudio connect <client> only when you want persistent native MCP tools
inside Claude Code, Codex, Cursor, or VS Code. A persistent client may need to
reconnect after its configuration or cached tool catalog changes.
See the Webstudio MCP documentation for setup, discovery, editing, verification, and safety guidance.
You can link a project from Webstudio Cloud with the following command:
webstudio link
This command will prompt you to paste a link which you can create using the Share option in your project.
Make sure to provide Build access when generating the link in Webstudio Cloud.
sync
Once the project is linked, use the sync command to sync it with the cloud:
webstudio sync
Sync downloads the current saved Builder project and its asset files, then prepares the local content index. Publishing is not required.
Use the export with webstudio build or webstudio import --to "<target-share-link>". Sync is not required for MCP editing.
build
Now, you can build your project with the build command:
webstudio build
During this phase, the CLI establishes the necessary routes and pages, scaffolding the entire application using the default Remix template. Additionally, all assets, such as images and fonts are downloaded to the assets folder inside the public directory.
Once the project is scaffolded, you can run npm install and then npm run dev to run your app in development mode.
If you want to build a production version of the app, you can run npm run build.
Deployment
Vercel
Once you've built the project locally, you can use the Vercel CLI to deploy your project directly to Vercel:
vercel deploy
Follow the instructions here to install the vercel CLI. We plan to add more deployment targets in future.
Netlify
If you want to deploy to netlify, you can use Netlify CLI to deploy your project directly to Netlify:
netlify deploy
You can configure the project to support netlify serverless/edge-functions respectively, as deployment target at the time of initially setting up your project. Please check the initiating-a-webstudio-project section.
You can manually change it using the build command. For serverless functions:
webstudio build --template netlify
Important Notes
If you use vercel build before vercel deploy, make sure to clean your app folder in the project afterward.
Vercel injects a few files to support and deploy Remix using their CLI, but these files are not necessary for your project when you use it locally.
