Frontend Init

Frontend Project Initialization

Opinionated setup using fast, Rust/Go-based tools.

Quick Start

# 1. Initialize
bun init my-project
cd my-project

# 2. Add tools (choose based on project type)
bun add -d oxlint oxfmt                              # app
bun add -d oxlint oxfmt tsdown @typescript/native-preview  # library

# 3. Configure oxlint
bunx oxlint --init

Add scripts to package.json:

{
  "scripts": {
    "lint": "oxlint src",
    "lint:fix": "oxlint src --fix",
    "format": "oxfmt src",
    "format:check": "oxfmt src --check",
    "typecheck": "tsgo"
  }
}

Project Types

Application

{
  "name": "my-app",
  "type": "module",
  "scripts": {
    "dev": "bun run --watch src/index.ts",
    "start": "bun run src/index.ts",
    "lint": "oxlint src",
    "format": "oxfmt src",
    "typecheck": "tsgo"
  }
}

Library (npm package)

bun add -d tsdown @typescript/native-preview

{
  "name": "my-lib",
  "version": "0.0.1",
  "type": "module",
  "main": "./dist/index.cjs",
  "module": "./dist/index.js",
  "types": "./dist/index.d.ts",
  "exports": {
    ".": {
      "import": "./dist/index.js",
      "require": "./dist/index.cjs",
      "types": "./dist/index.d.ts"
    }
  },
  "files": ["dist"],
  "scripts": {
    "dev": "tsdown --watch",
    "build": "tsdown",
    "prepublishOnly": "bun run build"
  }
}

tsdown.config.ts:

import { defineConfig } from "tsdown";

export default defineConfig({
  entry: ["src/index.ts"],
  format: ["esm", "cjs"],
  dts: true,
  clean: true,
});

React

bun init my-react-app --template react

Add to .oxlintrc.json:

{
  "plugins": ["react", "react-hooks"],
  "rules": {
    "react-hooks/rules-of-hooks": "error",
    "react-hooks/exhaustive-deps": "warn"
  }
}

Configuration

.oxlintrc.json

{
  "$schema": "./node_modules/oxlint/configuration_schema.json",
  "plugins": ["typescript", "unicorn", "import"],
  "rules": {
    "eqeqeq": "warn",
    "no-console": "warn",
    "import/no-cycle": "error"
  },
  "overrides": [
    {
      "files": ["*.test.ts", "*.spec.ts"],
      "rules": { "no-console": "off" }
    }
  ]
}

.oxfmtrc.json (optional)

Defaults work well. Custom if needed:

{
  "printWidth": 100,
  "semi": false,
  "singleQuote": true
}

tsconfig.json

Bun generates this. Ensure tsgo compatibility:

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "strict": true,
    "skipLibCheck": true,
    "noEmit": true
  },
  "include": ["src"]
}

.gitignore

node_modules/
dist/
*.log
.DS_Store

Editor Setup (VS Code / Cursor)

.vscode/settings.json:

{
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "oxc.oxc-vscode"
}

.vscode/extensions.json:

{
  "recommendations": ["oxc.oxc-vscode", "oven.bun-vscode"]
}

CI/CD

.github/workflows/ci.yml:

name: CI
on: [push, pull_request]
jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: oven-sh/setup-bun@v2
      - run: bun install
      - run: bun run lint
      - run: bun run format:check
      - run: bun run typecheck
      - run: bun run build # library only

Notes

Tool maturity: Bun, Oxlint, tsdown are stable. Oxfmt is alpha. tsgo is preview.

Migration from existing project:

1. Delete node_modules, lockfiles
2. bun install
3. bun add -d oxlint oxfmt
4. Remove eslint/prettier configs
5. Update scripts
