Installation

caution

Jess is in early alpha, so features and syntax are likely to change!

If you just want to compile a file and keep moving, use install-on-demand:

npx --yes --package jess jess my-file.jess my-file.css
pnpm --package=jess dlx jess my-file.jess my-file.css

For real project work, install locally:

pnpm add -D jess

Bundlers​

  • rollup-plugin-jess is available and compiles .jess files through the current Jess compiler.
  • Webpack-specific integration is still evolving.

That split is intentional: stable core path first, then framework/bundler ergonomics on top.
