@plato/eslint-config-ts

A shareable ESLint configuration for TypeScript projects at Plato.

Setup

Configuration

First, install this package, along with ESLint, TypeScript, and associated plugins, as development dependencies:

yarn add @plato/eslint-config-ts eslint typescript @typescript-eslint/eslint-plugin @typescript-eslint/parser --dev

ℹ️ Since the command above can be difficult to visually parse, the required development dependencies are:

• @plato/eslint-config-ts (this package)
• eslint
• typescript
• @typescript-eslint/eslint-plugin
• @typescript-eslint/parser

Next, add the ESLint configuration (which simply extends @plato/eslint-config-ts) to your project's package.json file:

{
	"eslintConfig": {
		"extends": "@plato/eslint-config-ts"
	}
}

ℹ️ You may also specify the ESLint configuration in a separate .eslintrc.json file.

Run the Linter

To easily run the linter from a shell, add a lint command to the scripts property of your project's package.json file:

{
	"scripts": {
		"lint": "eslint path/to/lint --ext .ts"
	}
}

Now you can run yarn lint to lint the project's code.

Editor Integration

Many editors support ESLint. Here are some common editors and associated ESLint plugins.

• Atom - linter-eslint
