Summary

The Apps page lists the mobile apps, the Mac app and the TUI, but not the browser extension, which brings /dev/null to GitHub: a /dev/null tab on organizations, a Commit button on repositories, issues and pull requests, and Follow buttons next to GitHub's. It is now on the Chrome Web Store, so this adds it to the page, like #1445 did for the TUI.

Disclosure: I built the extension (jubianchi/dev-null-ext), so the section credits me.

Changes

  • A "/dev/null for your browser" section after the TUI, with an Add to Chrome button linking to the Chrome Web Store. It reuses the Mac icons, as the TUI section does (the extension's icon is the same mark, but only 128 px).
  • A screenshot of the /dev/null tab on the dev-null-sh organization, in GitHub light and dark, following /dev/null's theme like the icons do. It has a hairline border so the light one doesn't blend into the page.
  • A "Browser extension" entry in KNOWLEDGE_BASE.md.

Validation

  • tsc, vp fmt --check, vp lint: passed. vp test run --config tests/draft-images.config.ts: 889 passed.
  • AppControllerTest and the knowledge base tests: passed.
  • No new test: the section is static content, and the Apps page has no content tests.

Visual evidence

Apps page as a guest, local app, Chrome. Before is production at f2423d6c, after is this branch at c09a3965.

Before, dark, 1440 px: the page ends with the TUI After, dark, 1440 px
After, light, 1440 px After, dark, 500 px

The GitHub screenshots were taken at 1000 px wide. My browser is in French, so the extension's relative dates were switched to English before capturing, from their datetime attributes.

Device verification

Not tested on a phone: Chrome wouldn't go below 500 px wide, and the change is a static section with a link and an image. Nothing overflows at 500 px. On a phone the screenshot gets small, as the TUI one already does.

Independent review

Reviewed by a separate read-only agent on base f2423d6c, head c09a3965: CODE: PASS and VISUAL: PASS on the captures above. It checked the links, image sizes, alt text, the theme switch, consistency with #1445, and that the page and knowledge base claim nothing the extension's README doesn't support.

Limitations

  • Chrome only: the extension isn't on Firefox Add-ons yet, so the page doesn't mention Firefox.
  • No capture at phone width.

Summary by CodeRabbit

  • New Features
    • Added a browser extension section with installation links, supported browser information, GitHub connection details, and light- and dark-mode screenshots.
    • Expanded the contents index with a link to the browser extension documentation.

Walkthrough

The Apps page and knowledge base now include information about the /dev/null GitHub browser extension, with links to its repository and Chrome Web Store listing. The Apps page also includes light- and dark-mode screenshots.

Changes: Browser Extension

Layer / File(s) Summary
Extension details and presentation
resources/js/pages/app/index.tsx, KNOWLEDGE_BASE.md
The Apps page and knowledge base describe the extension’s GitHub features, installation, supported browsers, and authorization. The Apps page includes light- and dark-mode screenshots. The knowledge base also describes disconnection by revoking the authorized device.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested reviewers: nunomaduro

Merge Risk: Low · up to c09a3

Mobile visitors may tap the installation link and be unable to use the extension; adding a desktop qualifier is a small documentation fix.

Limit the compatibility note to desktop browsers.

The section appears on phones, and the note does not say that the extension needs a desktop browser. Phone visitors can tap Add to Chrome and reach an install that they cannot complete. Add the desktop qualifier in the page and in the matching KNOWLEDGE_BASE.md entry.
