@rnx-kit/eslint-plugin

@rnx-kit/eslint-plugin is a set of configurations and rules that can be used as is, or extended in your own ESLint config.

Note that this plugin requires the new ESLint configuration format. If you still rely on the previous format, use version 0.5.x instead.

Install

yarn add @rnx-kit/eslint-plugin --dev

or if you're using npm:

npm add --save-dev @rnx-kit/eslint-plugin

Usage

This ESLint plugin exports multiple configurations. For instance, to use the recommended configuration, you can re-export it in your flat config like below:

module.exports = require("@rnx-kit/eslint-plugin/recommended");

Alternatively, if you want to add customizations:

const rnx = require("@rnx-kit/eslint-plugin");
module.exports = [
  ...rnx.configs.recommended,
  {
    rules: {
      "@rnx-kit/no-const-enum": "error",
      "@rnx-kit/no-export-all": "error",
    },
  },
];

If you're just interested in the rules, you can use it as a plugin and enable the rules you're interested in:

module.exports = [
  {
    plugins: {
      "@rnx-kit": require("@rnx-kit/eslint-plugin"),
    },
    rules: {
      "@rnx-kit/no-const-enum": "error",
      "@rnx-kit/no-export-all": "error",
    },
  },
];
