Presets

Flint’s package.json plugin provides the following preset:

Preset	Recommended	Description
logical	✅ Always	Common rules for finding bugs and good practices in package.json files.

Flint recommends using the logical preset:

flint.config.ts

import { defineConfig, packageJson } from "flint";

export default defineConfig({
  use: [
    {
      files: packageJson.files.all,
      rules: [packageJson.presets.logical],
    },
  ],
});

Note

Coming soon: more expansive documentation on choosing and combining plugins & presets with Flint.
