Gain insights into integrating TypeScript with React to improve productivity. Learn about strongly-typed props, state, and events, and set up projects using Create React App, Webpack, and Babel.

If you are a React developer and want to build your React apps faster and more robustly, this course is for you. Learn to integrate TypeScript with React, boost your productivity, and create apps that are easier to maintain.

In this course, you will learn how to utilize TypeScript’s sophisticated type system to make React development faster and your code more readable. You will learn how to create component props, state, and events that are strongly-typed, allowing you to quickly understand what you can pass and helping you avoid mistakes.

Lastly, you will set up React projects with TypeScript. First, you will learn how to do this with the Create React App tool, then how to create a React and TypeScript project with Webpack and Babel.

Using TypeScript with React

In the TypeScript configuration file, what option will turn strict mode on?

In the TypeScript configuration file, what option will turn strict mode on?

There is no such preset because the TypeScript compiler can be used to do this.

What Babel preset can be used to transform TypeScript code into JavaScript code?

What Babel preset can be used to transform TypeScript code into JavaScript code?

TSLint should be used to lint TypeScript rather than ESLint.

What ESLint plugin contains some linting rules for TypeScript?

What ESLint plugin contains some linting rules for TypeScript?

Add `"react/prop-types": "off"` into the `"rules"` section.

Add `"react/prop-types": false` into the `"rules"` section.

Add `"react/prop-types": "warn"` into the `"rules"` section.

In the ESLint configuration file, how can we suppress the `react/prop-types` rule?

In the ESLint configuration file, how can we suppress the <code>react/prop-types</code> rule?

The `entry` setting doesn't reference a TypeScript file.

The `module` `rules` don't include rules for TypeScript files.

The output bundle needs to have a `.ts` extension.

There are two problems with the following Webpack configuration for a React and TypeScript project. What are these two problems?

```
module.exports = {
  entry: './src/index.js',
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: ['babel-loader', 'eslint-loader'],
      },
    ],
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js'],
  },
  output: {
    path: path.resolve(__dirname, 'build'),
    filename: 'bundle.js',
  },
  devServer: {
    contentBase: path.join(__dirname, 'build'),
    compress: true,
    port: 4000,
  },
};
```
