Better GitHub PR View

A Manifest V3 browser extension that adds a compact metadata strip to GitHub repository pull request list rows.

It is narrowly scoped: on repository Pull requests pages, it augments each visible row with information that normally requires opening the PR first.

What it does

• Enhances repository Pull requests pages on github.com
• Adds compact inline row metadata that stays close to GitHub's native styling
• Surfaces commit count and files changed directly in the list
• Adds line-change totals and last-edited time
• Lets you keep or hide GitHub's native row metadata pieces like PR number, opened time, author, and task progress
• Hydrates visible rows only, with in-memory caching and bounded fetch concurrency
• Caches fetched PR metadata locally and supports manual cache clearing from the popup

Current scope

This version targets repository-level pull request list pages only:

• https://github.com/<owner>/<repo>/pulls

It does not modify issue lists or individual pull request detail pages.

Metadata shown

The extension can show:

• commit count
• files changed
• added and deleted line totals
• last edited time
• optional cache freshness state

It can also trim GitHub's native metadata line to keep only the pieces you want visible.

Install locally in Chrome

6. Select:

   /Users/maximilianmauroner/Documents/GitHub/better-github-pr-view/dist/chrome

Install locally in Firefox

1. Run bun install.

2. Run bun run build:firefox.

3. Use Firefox 142 or newer.

4. Open about:debugging#/runtime/this-firefox.

5. Choose Load Temporary Add-on.

6. Select:

   /Users/maximilianmauroner/Documents/GitHub/better-github-pr-view/dist/firefox/manifest.json

Build and package

1. Install dependencies:

   bun install

2. Create browser-specific builds:

   bun run build:chrome
   bun run build:firefox

3. Create upload artifacts:

   bun run pack:chrome
   bun run pack:firefox

Artifacts are written to:

• artifacts/better-github-pr-view-chrome-0.1.0.zip
• artifacts/better-github-pr-view-firefox-0.1.0.zip

Release validation

Run the full release check before uploading to either store:

bun run check:release

This command:

• typechecks the extension and Bun scripts
• builds Chrome and Firefox packages
• runs web-ext lint on the Firefox build
• verifies store docs and required assets exist
• creates versioned ZIP artifacts

GitHub downloads

Every push and pull request uploads the Chrome and Firefox ZIP files as GitHub Actions artifacts. Tagged releases also attach the same ZIP files to the GitHub Release page.

Release flow:

1. Update package.json with the next extension version.

2. Push the branch and confirm bun run check:release passes locally.

3. Create and push a matching tag:

   git tag v0.1.0
   git push origin v0.1.0

4. Download the release assets from:

   • the workflow run artifacts for CI builds
   • the GitHub Release page for tagged versions

The release workflow fails if the pushed tag does not match package.json.
