What this changes

jdk/image.jar is about 120 MB, over GitHub's 100 MB limit for a file in a git repository, so a site that publishes by pushing a gh-pages branch cannot hold it. The README and docs/browser.md now say to deploy GitHub Pages from Actions, which serves the file with Range requests.

Tests

Docs only. A Pages site deployed from Actions served a 125 MB file in full and answered a Range request with 206.

Noticed, not fixed

Right after a release, npm can list the new version a few minutes before it serves the tarball, so an install in that window gets a 404.

Summary

Summary by CodeRabbit

  • Documentation
    • Updated browser setup guidance to serve the package’s dist/ directory as static files.
    • Clarified that GitHub Pages deployments should use Actions: the large JAR file cannot be stored on a gh-pages branch, but can be served through an Actions deployment, including Range requests.

The browser setup and browser documentation now state that jdk/image.jar exceeds GitHub’s per-file limit. They direct GitHub Pages deployments to Actions and note that the deployed file supports Range requests.

Changes: GitHub Pages documentation

Layer / File(s) Summary
Document Actions-based deployment
README.md, docs/browser.md
The setup instructions direct GitHub Pages deployments to Actions because jdk/image.jar is too large for a gh-pages branch. The browser documentation notes that Actions-based Pages deployment serves the file with Range requests.

Merge Risk: Low · previous review e6138

The new GitHub Pages guidance does not say that project sites need the repository name in /app/ paths. Users following the example on a project site may fail to load their JAR. The fix is a short documentation note, and merging this change does not alter runtime behavior.

Full details: Title check

Explanation

The title names the main change: the docs now say GitHub Pages must deploy from Actions so that jdk/image.jar is served. The changeset updates README.md and docs/browser.md to say this, and the description gives the reason, which is that the 120 MB file exceeds GitHub's 100 MB limit for a git repository file. The title is specific and matches the objectives.

Full details: Description check

Explanation

The description follows the template. 'What this changes' explains the change and its reason (the 120 MB file exceeds GitHub's 100 MB limit, so a gh-pages branch cannot hold it, and Actions deployment serves it with Range requests). 'Tests' says the change is docs only and reports a manual check: a Pages site deployed from Actions served a 125 MB file in full and returned 206 for a Range request. 'Noticed, not fixed' lists the npm listing-versus-tarball 404 window. The template asks for behavior changes to be listed, but this docs-only change has none beyond the documentation itself, so the omission is minor.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files. (2 skipped: 2 unsupported.)

A rabbit checks the Pages path,
Then finds the jar too large to stash.
Through Actions, files take flight,
Range requests serve them right.
The README points the way.

Documentation update noting that jdk/image.jar exceeds GitHub's 100 MB file limit, so GitHub Pages must be deployed from Actions (using actions/upload-pages-artifact) rather than a gh-pages branch. The change is accurate and addresses a real deployment constraint.

Document the repository path for project Pages sites.

For a JAR at /repo/my-app.jar, the example requests /my-app.jar and may fail to load the intended JAR. Document the project-site path in both examples.

Documentation update explaining that GitHub Pages must deploy from Actions (not a gh-pages branch) because jdk/image.jar exceeds GitHub's 100 MB file limit. Both README.md and docs/browser.md now note this requirement and confirm Actions deployment serves the file with Range requests.
