@goparrot/eslint-config NPM

How to use

npm install --save-dev @goparrot/eslint-config

Installed libraries out of the box:

Choose the right set of rules

Create the `.eslintrc.js` file in the directory next to `package.json`

module.exports = {
  extends: ["@goparrot/eslint-config/recommended"],
  parserOptions: {
    project: "./tsconfig.eslint.json",
  },
  rules: {
    // rules to override.
  },
};

You should create the tsconfig.eslint.json in your project.

See the examples of tsconfig.json and tsconfig.eslint.json in this repository.

Choose the right set of rules

Common recommended rules:

extends: ['@goparrot/eslint-config/recommended']

Less strict rules:

extends: ['@goparrot/eslint-config/recommended', '@goparrot/eslint-config/less-strict']

For a frontend project with react and jsx:

npm install --save-dev eslint-plugin-react eslint-plugin-react-hooks

extends: ['@goparrot/eslint-config/recommended', '@goparrot/eslint-config/react', '@goparrot/eslint-config/jsx']

Create the `.eslintignore` file in the directory next to `.eslintrc.js`

# you must any dot `.file` which you want to ignore
# by default we don't ignore hidden `!.*.js` and `!.*.json` files in the root directory (for example: `.commitlintrc.js`, .`prettierrc.json`)
# example: if you don't want to ignore these files
!.eslintrc.js

# don't forget to add here all ignored folders or files from .gitignore that you don't need to check with a linter (there is no magic)
# by default we ignore `node_modules` and `.yalc` folders in the root directory
# example: if you want to ignore these files or directories
