Create A Blank Frontend Project In React + TS

=====================================================

In this article, we will guide you through the process of creating a blank frontend project in React using TypeScript. We will cover the necessary steps to set up a new project, including installing dependencies, configuring the project structure, and setting up the build process.

Prerequisites

Before we begin, make sure you have the following tools installed on your system:

  • Node.js: The latest version of Node.js (14 or higher) is required to run the project.
  • npm: The latest version of npm (6 or higher) is required to manage dependencies.
  • yarn: Yarn is a package manager that can be used as an alternative to npm.
  • Visual Studio Code: Visual Studio Code is a popular code editor that supports TypeScript and React development.

Step 1: Create a New Project

To create a new project, navigate to the terminal and run the following command:

npx create-react-app my-app --template typescript

This command will create a new React project with TypeScript support. The --template typescript flag tells Create React App to use the TypeScript template.

Step 2: Configure the Project Structure

The project structure created by Create React App is a good starting point, but we can customize it to suit our needs. Let's take a look at the project structure:

my-app/
public/
index.html
src/
components/
App.tsx
index.tsx
containers/
index.tsx
models/
index.ts
reducers/
index.ts
actions/
index.ts
utils/
index.ts
index.ts
tsconfig.json
package.json

We can see that the project structure is divided into several folders:

  • public: This folder contains the static assets of the project, such as the index.html file.
  • src: This folder contains the source code of the project.
  • components: This folder contains the React components of the project.
  • containers: This folder contains the container components of the project.
  • models: This folder contains the data models of the project.
  • reducers: This folder contains the reducers of the project.
  • actions: This folder contains the actions of the project.
  • utils: This folder contains the utility functions of the project.

Step 3: Configure the Build Process

The build process is configured in the package.json file. Let's take a look at the scripts section:

"scripts": {
  "start": "react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test"
},

We can see that there are three scripts:

  • start: This script starts the development server.
  • build: This script builds the project for production.
  • test: This script runs the tests.

Step 4: Configure TypeScript

TypeScript is configured in the tsconfig.json file. Let's take a look at the configuration:

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "node",
    "outDir": "build",
    "sourceMap": true,
    "declaration": true,
    "noImplicitAny": true
  }
}

We can see that the configuration is set to use the es5 target, which means that the code will be compiled to ES5 syntax. We also set the strict option to true, which means that TypeScript will enforce strict type checking.

Step 5: Start the Development Server

To start the development server, navigate to the terminal and run the following command:

npm start

This command will start the development server, and you can access the project at http://localhost:3000.

Step 6: Build the Project for Production

To build the project for production, navigate to the terminal and run the following command:

npm run build

This command will build the project for production, and you can access the project at http://localhost:3000.

Conclusion

In this article, we guided you through the process of creating a blank frontend project in React using TypeScript. We covered the necessary steps to set up a new project, including installing dependencies, configuring the project structure, and setting up the build process. We also configured TypeScript and started the development server. Finally, we built the project for production.

=====================================================

In this article, we will answer some frequently asked questions about creating a blank frontend project in React using TypeScript.

Q: What is Create React App?

A: Create React App is a tool that allows you to create a new React project with a single command. It sets up a new project with a basic structure, including a src folder, a public folder, and a package.json file.

Q: What is TypeScript?

A: TypeScript is a superset of JavaScript that adds optional static typing and other features to improve the development experience. It is designed to help catch errors early and improve code maintainability.

Q: Why use TypeScript with React?

A: Using TypeScript with React can help improve code maintainability, catch errors early, and improve code readability. It can also help with code completion and debugging.

Q: How do I configure TypeScript in my project?

A: To configure TypeScript in your project, you need to create a tsconfig.json file in the root of your project. This file contains the configuration options for TypeScript.

Q: What is the difference between src and public folders?

A: The src folder contains the source code of your project, while the public folder contains static assets, such as images and CSS files.

Q: How do I start the development server?

A: To start the development server, navigate to the terminal and run the following command:

npm start

Q: How do I build the project for production?

A: To build the project for production, navigate to the terminal and run the following command:

npm run build

Q: What is the purpose of the package.json file?

A: The package.json file contains metadata about your project, including the dependencies and scripts.

Q: How do I add dependencies to my project?

A: To add dependencies to your project, navigate to the terminal and run the following command:

npm install <dependency-name>

Q: How do I run scripts in my project?

A: To run scripts in your project, navigate to the terminal and run the following command:

npm run <script-name>

Q: What is the difference between npm and yarn?

A: npm and yarn are both package managers, but they have some differences. yarn is generally faster and more secure than npm.

Q: How do I switch from npm to yarn?

A: To switch from npm to yarn, navigate to the terminal and run the following command:

yarn install

Q: What is the purpose of the tsconfig.json file?

A: The tsconfig.json file contains the configuration options for TypeScript.

Q: How do I configure the tsconfig.json file?

A: To configure the tsconfig.json file, need to add or modify the configuration options in the file.

Q: What is the difference between es5 and esnext targets?

A: The es5 target means that the code will be compiled to ES5 syntax, while the esnext target means that the code will be compiled to the latest version of JavaScript.

Q: How do I configure the target in the tsconfig.json file?

A: To configure the target in the tsconfig.json file, you need to add the target option to the compilerOptions section.

Q: What is the purpose of the strict option in the tsconfig.json file?

A: The strict option enables strict type checking in TypeScript.

Q: How do I configure the strict option in the tsconfig.json file?

A: To configure the strict option in the tsconfig.json file, you need to add the strict option to the compilerOptions section.

Q: What is the difference between allowJs and noEmit options in the tsconfig.json file?

A: The allowJs option allows JavaScript files to be compiled, while the noEmit option prevents the compiler from emitting output.

Q: How do I configure the allowJs and noEmit options in the tsconfig.json file?

A: To configure the allowJs and noEmit options in the tsconfig.json file, you need to add the allowJs and noEmit options to the compilerOptions section.
