I build TurnShift, a team calendar in Slack. People book their shifts or take turns, and Slack tells everyone who is on.
Open source I made, all sponsored by TurnShift:
- iron-session: secure, stateless, cookie-based sessions for JavaScript.
- tzdb: always up to date time zones for time zone pickers.
- gifify: convert any video file to an optimized animated GIF.
- lazyload: lazyload images and iframes until they are visible.
