Node.js Plugin

Flint’s Node.js plugin includes rules targeted to code that runs in Node.js and Node.js-like environments.

npm

npm install @flint.fyi/plugin-node

pnpm

pnpm install @flint.fyi/plugin-node

yarn

yarn install @flint.fyi/plugin-node

Presets

Flint’s Markdown plugin provides the following presets:

Preset	Recommended	Description
logical	✅ Always	Common rules for finding bugs and enforcing good logical practices in Markdown files.
stylistic	✅ Always	Common rules for consistent styling and best stylistic practices in Markdown files.
stylisticStrict	☑️ When Ready	Additional rules for consistent styling and best stylistic practices in Markdown files.

If you are just getting started with linting, Flint recommends using the logical and stylistic presets:

flint.config.ts

import { node } from "@flint.fyi/node";
import { defineConfig, ts } from "flint";

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

If you are experienced with both Markdown and linting, Flint recommends additionally using the stylisticStrict preset:

flint.config.ts

import { node } from "@flint.fyi/node";
import { defineConfig, ts } from "flint";

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

Note

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

logical

Rules that find bugs and enforce good Node.js and general server-side best practices for most-to-all JavaScript and TypeScript files.

flint.config.ts

import { defineConfig, node } from "flint";

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

stylistic

Rules that enforce consistent styling and best stylistic practices for most-to-all JavaScript and TypeScript files dealing with Node.js APIs.

flint.config.ts

import { node } from "@flint.fyi/node";
import { defineConfig, ts } from "flint";

export default defineConfig({
  use: [
    {
      files: ts.files.all,
      rules: node.presets.stylistic,
    },
  ],
});

stylisticStrict

Additional stylistic rules that enforce best practices which are not always straightforward to implement. These rules are recommended for projects where a majority of developers are experienced with both Node.js and using a linter.

flint.config.ts

import { node } from "@flint.fyi/node";
import { defineConfig, ts } from "flint";

export default defineConfig({
  use: [
    {
      files: ts.files.all,
      rules: node.presets.stylisticStrict,
    },
  ],
});

This preset’s rules are a superset of those in stylistic.
