This was one of the most painful review experience of my life. The commit history is anything but helpful. There's no context whatsoever on 90% of changes that are not directly related to vite. The 2/3rd of that stack that was generated by the bot had one single commit that was "ok". The rest was just the bot hallucinating some issues, hallucinating neutrino, fixing something that was already "fixed" before but in a worse way, claiming that it fixed something when it, in fact, made things worse.
Commits were also not reviewable by themselves and I had to jump back and forth to untangle whether a hunk was salvageable or not, having to try and reconstruct what the author was doing across multiple commits.
IMO the bot shouldn't be involved like this and those commits shouldn't have made it into the review without any review by the whoever pushed the stack. The time that it "saved" you is not worth the time and frustration it took me to disentangle the hallucinations and bad code.
Overall it ends up somewhat working with a few bugs and a lot of unused code and missing reasoning for changes that I think are worth adding to the different commit messages.

This logs the entire file every single time. Probably forgot to remove it?

Any idea why it was checking for existence before and you're not anymore? Is the env supposed to change and needs to be rewritten? Or will the write fail on the second go around?

Would be nice to explain in the commit why rollup is necessary and why the other bump comes with it so reviewers wouldn't have to go digging

I think this is the wrong polyfill here and you want https://www.npmjs.com/package/url instead?

For context, this is used in the docs when clicking on any link. With the current url polyfill it throws Uncaught TypeError: url.parse is not a function

Would've been nice to know why we need those because most of them are actually used by transitive dependencies
- crypto-browserify -> crypto -> used directly in
src/utils/memoize.js - stream-browerify -> stream -> used by
@taskcluster/client-web - stream-http -> http, used by ws
- https-browserify -> https, used by ws
- browserify-zlib -> zlib, used by ws (for permessage-deflate)
- url -> url, used by catch-links/index.js (see message above since it's wrong right now)
- querystring-es3 -> querystring, docker-exec-websocket-client/src/client.js
- buffer -> buffer, src/components/Shell/index.jsx (Buffer.alloc)
- vm-browserify -> vm, used by asn1.js, which comes from crypto-browserify
- path-browserify -> path, jsonlint from src/components/CodeEditor/json-lint.js
- util used in browserify-zlib
AFAICT process isn't used. I checked the output with process dropped and it seemed to not be used. Probably can remove it
Worth noting here that we should remove docker-exec-websocket-client in a followup since docker worker is gone now.

This makes no sense. We're building a static bundle. There's no difference between dev and production dependencies. If anything, everything is a dev dependency and should be moved there. This commit makes it sound like it fixes something when it's a complete no-op.
And if we want to use both deps/dev-deps to mark "this is a tool" and "this is something getting bundled" then it missed @mdx-js/rollup.

In classic claude fashion, the bot gave up without even trying and decided that the worst possible way of fixing this was the only way.
There's no mention of the error it triggers which rejects bare JSON imports without an 'assert { type: "json" }' attribute is as pretty much as vague as one can get "it didn't work, something about json on the json file".
Worse, this "fixes" a previous commit in the stack that was also supposed to fix it. Overall this is not good, we should find why it's failing if it even is, document what got tried to fix it, give context and proper errors instead of just "let's add 250 lines of random JSON to the codebase"

Finally something the bot got "right". Although the threat here is basically non existent, it's still fixing something the correct way.
I'd rather write it like this though and avoid the double try/catch:
try {
const code = fs.readFileSync(onScrollFile, "utf-8");
if (!code.includes(WRONG_CODE)) return;
fs.writeFileSync(onScrollFile, code.replace(WRONG_CODE, ""));
console.log(`Fixed react-virtualized in ${onScrollFile}`);
} catch (e) {
// Ignore write failures; vite will surface the underlying problem.
}

…itest
Replace the webpack 4 + Jest 26 toolchain with Vite 7 + Vitest 4.
Key changes:
Build & config:
- Add vite.config.js with Node.js polyfill aliases, MDX 3 pipeline
(remark-gfm, remark-frontmatter, rehype-prism-plus), history fallback
for SPA routing, and react-virtualized compatibility patch
- Add vitest.config.js + vitest.setup.js replacing jest.config.js +
jest.setup.js
- Move index.html to repo root (Vite convention), add docs/index.html
for multi-page build, delete old ui/src/index.html
- Extract env.js generation into generate-env-js.js (shared between
Vite plugin and Docker entrypoint)
- Update Dockerfile to run vite build and serve from ui/build/
- Update docker-compose generator to mount generate-env-js.js
- Update netlify.toml redirects for Vite output structure
- Delete jest config, jest transforms, and tsconfig.json
Source changes:
- Convert MDX doc comments from HTML (<!-- -->) to JSX ({/* */})
for MDX 3 compatibility
- Replace react-gh-like-diff with react-diff-viewer-continued
(maintained fork, Vite compatible)
- Add dedicated Documentation/components/Code component for
rehype-prism-plus
- Replace dynamic require() calls with import.meta.glob for doc loading
- Vendor JSON meta-schemas as ES modules (ajv no longer fetches at
runtime)
- Remove all webpackChunkName comments from dynamic imports
- Update test files from Jest globals to Vitest (vi.fn, vi.mock, etc.)
- Update snapshot format for Vitest

What this is
A migration of the UI from webpack 4 / jest 26 to vite + vitest, building on Boris's and Yaraslau's work in #8044.
This PR carries forward all the substantive work from #8044 — see the per-author commit attribution in the history below — plus the additional fixes needed to take the work to green CI. The history has been rewritten as a linear sequence on top of
mainto make review easier, rather than preserving #8044's 17 small fixup commits + a merge.Commit structure
Boris/Yaraslau commits keep their original authorship; new continuation work is authored as
Taskcluster Bot. Each commit's content mirrors a logical chunk of the original work where possible.Done in this PR (vs. #8044)

Boris's PR has been stalled since 2026-03-12 because the team had higher-priority work. Rather than force-push on top of his branch, this PR carries the work forward without disturbing #8044. If Boris or Yaraslau prefer to finish the work themselves on #8044, this PR can be closed without affecting that branch.
