How do I upgrade my React app to TypeScript?

To upgrade your React app to TypeScript, you need to install TypeScript and the necessary type definitions. Would you like a step-by-step guide?

Yes, please provide the steps.

First, install TypeScript and the React types using npm:

npm install --save typescript @types/react @types/react-dom

Next, rename your .js files to .tsx for components and .ts for other files. Do you need help with configuring TypeScript?

What should I include in the tsconfig.json file?

In your tsconfig.json, you should include settings like this:

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "react-jsx"
  },
  "include": ["src"]
}
