Edenspiekermann ESLINT Configuration

This repository contains the ESLINT configuration for projects at EdenSpiekermann.


$ npm i -D @edenspiekermann/eslint-config


Add some ESLint config to your package.json:

    "name": "my-javascript-project",
    "eslintConfig": {
        "extends": ["@edenspiekermann/eslint-config"]

Or to .eslintrc.json:

    "extends": ["@edenspiekermann/eslint-config"]

Depending on how you automate your JS linting you may wish to add a lint task to the scripts block in your package.json If this is your preferred setup simply add the following task.

    "scripts": {
        "lint": "eslint --fix path/to/your/javascript/**/*.js"

You can now use this task by running npm run lint.

Core rules

Using "extends": ["@edenspiekermann/eslint-config"] is a short hand for "extends": ["@edenspiekermann/eslint-config/rules/core"]. The core rules use extend the airbnb-base configuration. It contains all rulesets for a frameworkless / vanilla js validation. On top of that its possible to extend these rules with some more specific configurations (see the following).

Prettier rules

Add this configuration if you want to use eslint with prettier. For more details read the section Integrating with Prettier.

  "extends": [


Use "@edenspiekermann/eslint-config/rules/react" and "@edenspiekermann/eslint-config/rules/react-proptypes" configurations if you want to use eslint with react. "@edenspiekermann/eslint-config/rules/react" is mostly a proxy configuration for airbnb configuration. It disables the proptype validation. If you want to re-enable them, you should also add the "@edenspiekermann/eslint-config/rules/react-proptypes" rules.

  "extends": [


Enable "@edenspiekermann/eslint-config/rules/jest" when using jest in your project. It uses the jest/recommended and jest/style rules.

  "extends": [


To add typescript support for eslint extend the configuration with "@edenspiekermann/eslint-config/rules/typescript". This enabled typescript validation for *.ts files. When using typescript with react, you can also add "@edenspiekermann/eslint-config/rules/typescript-react" which adds jsx support for *.tsx files.

Integrating with Prettier

The config here is actually simply a proxy for Airbnb, prettier and prettier react configurations with a few custom overrides built in. One way you can have this code formatted on save though is through an ESLint integration in your code editor. We use the ESLint plugin for VSCode and this is configured to run on save. The code is then formatted and any errors highlighted in the editor window.

Installing the ESLint extension in VSCode

  • In VSCode you can select View > Extensions or shift + cmd + x to view the extensions sidebar and search the marketplace for the extension. Install and restart VSCode.

  • Next, select ESLint in the list of extensions and you will see the options that must be configured to enable format on save.

  • select Code > preferences > settings or cmd + , to adjust the ESLint configuration settings listed in the extension's README to format your code on save.

For other editors the instructions are basically the same, install the linting tool, sublime-linter for sublime or linter-eslint for Atom for example, and configure your settings to run and format on save.
