📦 Releases · 🐞 Report Bug · ✨ Request Feature

Installation

The recommended way to install the package is via NPM. It pairs nicely with module bundlers such as Webpack or Browserify:

npm i -D @croct/eslint-plugin

This plugin uses ESLint's flat config format (ESLint v9+).

JavaScript

For JavaScript projects, create an eslint.config.mjs file:

import { defineConfig } from 'eslint/config';
import croct from '@croct/eslint-plugin';

export default defineConfig(
    croct.configs.javascript,
);

TypeScript

For TypeScript projects, create an eslint.config.mjs file:

import { defineConfig } from 'eslint/config';
import croct from '@croct/eslint-plugin';

export default defineConfig(
    croct.configs.typescript,
);

The TypeScript config includes the JavaScript preset, so there's no need to include both.

React

For React projects, create an eslint.config.mjs file:

import { defineConfig } from 'eslint/config';
import croct from '@croct/eslint-plugin';

export default defineConfig(
    croct.configs.react,
);

The React config includes the JavaScript preset, so there's no need to include both.

Cypress

For Cypress projects, create an eslint.config.mjs file:

import { defineConfig } from 'eslint/config';
import croct from '@croct/eslint-plugin';

export default defineConfig(
    croct.configs.cypress,
);

The Cypress config includes the JavaScript preset, so there's no need to include both.

Custom rules

You can add custom rules or override existing ones:

import { defineConfig } from 'eslint/config';
import croct from '@croct/eslint-plugin';

export default defineConfig(
    croct.configs.typescript,
    {
        files: ['src/**/*.ts'],
        rules: {
            '@typescript-eslint/explicit-function-return-type': 'off',
        },
    },
);

For the list of available presets and rules, see the reference documentation.

Basic usage

Run the following command to check if the project adheres to the coding standard:
