eslint-config-tamia

eslint-config-tamia

This package provides a shared ESLint config that I use on all my projects.

Should be used with Prettier, has no own code style rules.

Usage

We export three ESLint configurations:

eslint-config-tamia

Base set of rules for JavaScript. Includes:

• eslint-plugin-unicorn

npm install --save-dev eslint eslint-config-tamia

eslint.config.mjs:

import tamia from 'eslint-config-tamia';
export default [...tamia];

eslint-config-tamia/react

Lints ES6+ and React. Includes:

• eslint-plugin-react
• eslint-plugin-unicorn

npm install --save-dev eslint eslint-config-tamia

eslint.config.mjs:

import tamiaReact from 'eslint-config-tamia/react';
export default [...tamiaReact];

eslint-config-tamia/typescript

Lints TypeScript. Includes:

• typescript-eslint
• eslint-plugin-unicorn

npm install --save-dev eslint eslint-config-tamia

eslint.config.mjs:

import tamiaTypeScript from 'eslint-config-tamia/typescript';
export default [...tamiaTypeScript];

eslint-config-tamia/typescript-react

Lints TypeScript and React. Includes:

• typescript-eslint
• eslint-plugin-react
• eslint-plugin-unicorn

npm install --save-dev eslint eslint-config-tamia eslint-plugin-jsx-a11y

eslint.config.mjs:

import tamiaTypeScriptReact from 'eslint-config-tamia/typescript-react';
import jsxAccessibility from 'eslint-plugin-jsx-a11y';

export default [
  ...tamiaTypeScriptReact,
  jsxAccessibility.flatConfigs.strict
];

Code style at a glance

• Tab indentation.
• Single-quotes.
• Semicolons.
• Declare variables just before their first usage.
• Multiple variable statements over multiple variable in a single statement.
• Make const, not var.
• Use === and !== over == and !=.
• Return early.
• Limit line lengths to 80 chars.
• Prefer readability over religion.
• Use ES6.

Example:

function eatFood(food) {
  if (food.length === 0) {
    return ['No food'];
  }

  return food.map(dish => `No ${dish.toLowerCase()}`);
}

const food = ['Pizza', 'Burger', 'Coffee'];
console.log(eatFood(food));
