refactor: Replace ESLint with Biome for faster linting and formatting

[Abdelkaderbzz]

Description

Migrate from ESLint to Biome for a faster, more modern linting and formatting experience.

Problem with current setup

• ESLint is slower compared to modern alternatives
• Requires multiple plugins for TypeScript, React, etc.
• Separate tools needed for formatting (Prettier)

Benefits of Biome

• 10-100x faster than ESLint/Prettier
• Single tool for linting AND formatting
• First-class TypeScript and React support
• Zero config to get started
• Compatible with most ESLint rules

Implementation

Install Biome

bun add -D @biomejs/biome
bunx biome init

Update package.json scripts

{
  "scripts": {
    "lint": "biome lint .",
    "lint:fix": "biome lint --write .",
    "format": "biome format --write .",
    "check": "biome check --write ."
  }
}

Remove old dependencies

bun remove eslint @eslint/js eslint-plugin-react-hooks eslint-plugin-react-refresh typescript-eslint globals

Migrate rules

Run bunx biome migrate eslint to convert existing rules

Files to modify

• package.json
• Delete eslint.config.js
• Create biome.json
• Update CI workflows if applicable
