jsr

JSR is a modern package registry for JavaScript and TypeScript. This skill covers creating, configuring, documenting, and publishing ESR packages with minimal overhead.

To create a package:

1. Write code in TypeScript as ESM (using import/export)
2. Create config - jsr.json (or add JSR properties to deno.json):

   {
     "name": "@scope/package-name",
     "version": "1.0.0",
     "exports": "./mod.ts"
   }
   

3. Publish - npx jsr publish or deno publish
