JSR Package Info

jsr/package-info

One JSR package: description, latest version, version count, JSR score, runtime compatibility (browser, Deno, Node.js, Workers, Bun), linked GitHub repository, dependency and dependent counts, archived and featured status. Version history is in the JSR package versions tool. Data from JSR, https://jsr.io, modified by Eden Engine (fields renamed and reduced); not an official JSR or Deno Land product.

Data source

JSR

Package data from JSR, the JavaScript Registry, https://jsr.io, fetched through its public API. Modified by Eden Engine: fields renamed and reduced (publisher and repository numeric ids and fields the list endpoints leave empty are dropped) and served by Eden Engine; this is not an official JSR or Deno Land product.
