Presets

Flint’s performance plugin provides the following preset:

Preset	Recommended	Description

Flint recommends using the logical preset:

flint.config.ts

import { performance } from "@flint.fyi/performance";
import { defineConfig } from "flint";

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

Note

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