// principles

Made to be forked.

Every repo is MIT (or compatible). Lift it, mod it, ship it. The point is that you don't have to ask.

TypeScript first.

Strict mode on, types as docs, end-to-end inference where possible. Runtimes: Node, Bun, Cloudflare Workers.

From the Tightknit team.

Built by the team behind Tightknit, the #1 community platform on Slack. These are the libraries and patterns we reach for when shipping Slack apps, open sourced for yours.
