Essential Configuration Files

tsconfig.json
TypeScript compiler configuration
.js
{
  "compilerOptions": {
    "target": "ES2020",
    "lib": ["DOM", "DOM.Iterable", "ES6"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx"
  },
  "include": ["src"],
  "exclude": ["node_modules"]
}

This is a good starting configuration for React projects. Most tools will generate this for you.

package.json Scripts
Useful npm scripts for TypeScript projects
.js
"scripts": {
  "dev": "next dev",
  "build": "next build",
  "start": "next start",
  "type-check": "tsc --noEmit",
  "lint": "eslint . --ext .ts,.tsx",
  "lint:fix": "eslint . --ext .ts,.tsx --fix",
  "format": "prettier --write ."
}

Run `npm run type-check` to verify your TypeScript without building. Great for CI/CD!

Remember: You"re Not Alone!

When You Get Stuck:

  • Check the error message carefully - TypeScript errors are usually helpful
  • Use your IDE's "Quick Fix" suggestions
  • Search Stack Overflow with the exact error message
  • Ask in the TypeScript Discord or Reddit

Pro Tips:

  • Start with `any` and gradually add proper types
  • Use the TypeScript playground to experiment
  • Read other people's TypeScript code on GitHub
  • Don't try to learn everything at once
