NPM Update Checker for Zed IDE

Highlights outdated npm packages and changelogs in package.json files minimalistically using a Rust LSP.

Features

• 📥 Highlights outdated packages in package.json
• 🔍 Changelog between current version and latest version
  • Parses and combines GitHub releases and/or CHANGELOG.md
  • Shows changes from current to latest if possible
  • Goes direct without API calls with rate limits
• 🔧 Offers auto-complete to update the package
  • Shows available release tracks
  • Includes fallback update targets from the current track (older than latest, newer than current)
• 📚 Distinguishes between release tracks (major/minor/patch/canary/nightly/beta/alpha/experimental)

Auto-completions

Zed auto-complete to upgrade quickly with the option to show multiple recent releases on current track.

Optional loading Indicator

For an inlay loading indicator, enable inlay hints in Zed: ```json // settings.json { "inlay_hints": { "enabled": true } } ```
