@oxlint/plugins

Plugin utilities for Oxlint.

This package provides optional functions to assist in creating Oxlint JS plugins and rules.

Installation

npm install @oxlint/plugins

Usage

Define functions

Use definePlugin and defineRule if authoring your plugin in TypeScript for type safety.

import { definePlugin, defineRule } from "@oxlint/plugins";

const rule = defineRule({
  create(context) {
    return {
      Program(node) {
        // Rule logic here
      },
    };
  },
});

export default definePlugin({
  meta: { name: "oxlint-plugin-amazing" },
  rules: { amazing: rule },
});

Types

This package also includes types for plugins and rules.

import type { Context, Rule, ESTree } from "@oxlint/plugins";

const rule: Rule = {
  create(context: Context) {
    return {
      Program(node: ESTree.Program) {
        // Rule logic here
      },
    };
  },
};

ESLint compatibility

If your plugin uses Oxlint's alternative createOnce API, use eslintCompatPlugin to convert the plugin so it will also work with ESLint.

import { eslintCompatPlugin } from "@oxlint/plugins";

const rule = {
  createOnce(context) {
    return {
      Program(node) {
        // Rule logic here
      },
    };
  },
};

export default eslintCompatPlugin({
  meta: { name: "oxlint-plugin-amazing" },
  rules: { amazing: rule },
});

Node.js version

This package requires Node.js 12.22.0+, 14.17.0+, 16.0.0+, or later. This matches the minimum Node.js version required by ESLint 8.

This package provides both ESM and CommonJS entry points.

So a plugin which depends on @oxlint/plugins can be:

• Used with any version of Oxlint.
• Used with ESLint 8+.
• Published as either ESM or CommonJS.
