ESLint Prettier Boilerplate

Starter repository for a JS project using ESLint and Prettier recommended rules and styles.

Installation

Clone the Git repository.

git clone https://github.com/travishorn/eslint-prettier-boilerplate.git

Install the dependencies.

npm install

Since you are probably using this as a base for a new project, you probably also want to remove the origin remote.

git remote remove origin

You may also want to remove the git tags.

For *nix, run

git tag | xargs -L 1 | xargs git tag --delete

For Windows, run

FOR /f "tokens=*" %a in ('git tag') DO git tag -d %a

Usage

Start developing.

Any files with extension .js can be linted against ESLint and Prettier recommended rules.

npm run lint

You can automatically fix some problems.

npm run lint:fix

Editor Setup

If you're using Visual Studio Code, you can install the ESLint extension, which will automatically highlight warnings and errors using this boilerplate.

1. Press Ctrl + Shift + X or click the Extenstions button
2. Search for ESLint
3. Click the Install button next to the ESLint search result

With this extension, you can also choose to automatically fix/format your code when you save. Add the following to your Visual Studio Code settings.

"eslint.autoFixOnSave": true

This setting only takes effect if files.autoSave is set to off, onFocusChange, or onWindowChange.

Manual Setup (without using this repository)

Initialize an npm package.

npm init -y

Install development dependencies

npm i -D eslint eslint-config-prettier eslint-plugin-prettier prettier

Create .eslintrc.js in project root.

module.exports = {
  "extends": [
    "eslint:recommended",
    "plugin:prettier/recommended"
  ],
  "env": {
    "es6": true,
    "node": true
  },
  "parserOptions": {
    "ecmaVersion": 8
  }
};
