Why use this config?

• Best practices focused in modern features and principles (SOLID, DRY, KISS, Clean Code)
• Constant maintenance
• More complete: Includes more features than other configs, like AirBnB
• Ready-to-go: You don't need any extra config
• Bye bye prettier: You don't need to be using the prettier extension for VSCode

Install

This config needs prettier and eslint to work, as it is only a config and not the real package.

pnpm add -D @econominhas/eslint-config eslint prettier

Obs: If you are using VSCode, you may need/want to do some extra steps.

Basic Usage

1 - Create a .eslintrc.js file in the root of your project

2 - Put the following content inside the file:

module.exports = {
	root: true,
	extends: "@econominhas",
};

3 - Restart VSCode, and it's done!

Modules

Alert: After any change at .eslintrc.js file, you should restart VSCode to ensure that it's working properly. This is a limitation of ESLint/VSCode, not our config.

Alert: The common module must ALWAYS be extend, and must ALWAYS be the fist one.

This repository contains the best practices divided by libs, frameworks and tools. The currently existent modules are:

Common

The common module is the default rules used by every javascript project. It doesn't contains any special config for frameworks, backend, frontend or npm package. You must import this module if you want to use any of the other modules of this package.

Usage

Create an .eslintrc.js file in the root folder of your package and add this content to it:

module.exports = {
	root: true,
	extends: "@econominhas",
};

Jest

Specific configs to projects that uses Jest.

Usage

Create an .eslintrc.js file in the root folder of your package and add this content to it:

/* eslint-disable @typescript-eslint/no-var-requires */
/* eslint-disable @typescript-eslint/no-require-imports */

module.exports = {
	root: true,
	extends: [
		"@econominhas", // The common module always should be extended!
		"@econominhas/eslint-config/jest",
	],
	settings: {
		jest: {
			version: require("jest/package.json").version,
		},
	},
};

TypeScript

Specific configs for typescript projects.

Usage

Create an .eslintrc.js file in the root folder of your package and add this content to it:

module.exports = {
	root: true,
	extends: [
		"@econominhas", // The common module always should be extended!
		"@econominhas/eslint-config/typescript",
	],
};

Using another tsconfig for linting

By default, this module uses tsconfig.json file for configuring the typescript for the project, but you can use another file specifically for linting.

To use another file, simply add this to your .eslintrc.js file:

/// .eslintrc.js
module.exports = {
	// ...
	parserOptions: {
		project: "tsconfig.lint.json", // <<< Name of the tsconfig file here (Must be in the root folder of the project)
	},
	// ...
};

Combining Modules

You can safely combine some modules, like this:

module.exports = {
	root: true,
	extends: [
		"@econominhas", // The common module always should be extended!
		"@econominhas/eslint-config/typescript",
		"@econominhas/eslint-config/jest",
	],
};

Extra - VSCode Tips & Tricks

See the errors and warnings

• Go to the VSCode Extensions Store
• Search for dbaeumer.vscode-eslint and install it

Auto fix (most of) errors and warnings

Obs: You need to have the ESLint extension installed.

Add this to the project's .vscode/settings.json file:

{
	// Make ESLint fix all the things that he can on save (like prettier formatting)
	"editor.codeActionsOnSave": {
		"source.fixAll.eslint": "always"
	},

	// Remove formatter to avoid conflicts
	"[javascript]": {
		"editor.defaultFormatter": null
	},
	"[typescript]": {
		"editor.defaultFormatter": null
	},
	"[javascriptreact]": {
		"editor.defaultFormatter": null
	},
	"[typescriptreact]": {
		"editor.defaultFormatter": null
	}
}
