Happy CLI (Fork)
This is a personal fork of happy-cli from the amazing Happy project.
All credit goes to the original authors. I've made some tweaks for my own self-hosted setup, but my changes are too scattered and experimental to submit upstream. If you're looking for the official version, please visit github.com/slopus/happy-cli.
Fork Changes
- Renamed package to
@zhigang1992/happy-cli for personal npm publishing
- Changed default server URLs to
happy-server.innopals.com and happy.innopals.com
- Switched from yarn to bun
- Lazy download of tools to reduce package size (~110MB to ~186KB)
- Added image attachment support in messages
- Improved push notifications with folder name
- Various bug fixes and improvements
