CI npm

@lasalefamine/eslint-config-base

Base config for ESlint - no React

Our default export contains all of our ESLint rules, including ECMAScript 6+. It requires eslint, eslint-plugin-import, eslint-plugin-simple-import-sort, @typescript-eslint/eslint-plugin, @typescript-eslint/parser and typescript

Install

First install the dependencies:

yarn add --dev eslint eslint-plugin-import eslint-plugin-simple-import-sort @typescript-eslint/eslint-plugin @typescript-eslint/parser typescript

Then add our config:

yarn add --dev @lasalefamine/eslint-config-base

Usage

@lasalefamine/eslint-config-base

Add to your .eslintrc

{
  "extends": "@lasalefamine/eslint-config-base",
  "parserOptions": {
    "project": "tsconfig.json"
  }
}

tsconfig.eslint.json

Create a new tsconfig.eslint.json files for overrides the include and exclude of your main tsconfig.json, so that ESLint will be able to lint everything without complaining:

{
  "extends": "./tsconfig.json",
  "exclude": [
    "node_modules"
  ],
  "include": [
    "**/*.js",
    "**/*.ts",
    "**/*.tsx"
  ]
}

And in your .eslintrc:

{
  "extends": "@lasalefamine/eslint-config-base",
  "parserOptions": {
    "project": "tsconfig.eslint.json"
  }
}

The parserOptions.project issue

You may wonder why you need to add an extra tsconfig.eslint.json file: this is kinda a problem with some rules that come from @typescript-eslint that need type information during the linting process, this is why you need to add a projectOptions.project to your .eslintrc. At this point ESLint will lint only files specified within the include array of the tsconfig you choose, this actually why you need to create a new tsconfig.eslint.json, extends your main tsconfig for having type information available to ESLint and then just re-include everythin you need to lint.
