eslint-config-betabong v0.0.2

eslint-config-betabong

Based on antfu/eslint-config, apart from the following changes:

• Semi quotes, no single
• Slightly less strict: e.g. Only warn on unused vars

Other than that, it's the same as the original:

• Auto fix for formatting (aimed to be used standalone without Prettier)
• Designed to work with TypeScript, Vue out-of-box
• Lint also for json, yaml, markdown
• Sorted imports, dangling commas
• Reasonable defaults, best practices, only one-line of config

Usage

Install

yarn add -D eslint eslint-config-betabong

Config .eslintrc

{
	"extends": "@betabong"
}

You don't need .eslintignore normally as it has been provided by the preset.

Add script for package.json

For example:

{
	"scripts": {
		"lint": "eslint .",
		"lint:fix": "eslint . --fix"
	}
}

Config VS Code auto fix

Install VS Code ESLint extension and create .vscode/settings.json

{
	"prettier.enable": false,
	"editor.formatOnSave": false,
	"editor.codeActionsOnSave": {
		"source.fixAll.eslint": true
	}
}

You can also do it on a project basis, add .vscode/settings.json to your project root.

TypeScript Aware Rules

Type aware rules are enabled when a tsconfig.eslint.json is found in the project root, which will introduce some stricter rules into your project. If you want to enable it while have no tsconfig.eslint.json in the project root, you can change tsconfig name by modifying ESLINT_TSCONFIG env.

// .eslintrc.js
process.env.ESLINT_TSCONFIG = 'tsconfig.json';

module.exports = {
	extends: '@antfu',
};
