Setting Up a TypeScript Project – Step-By-Step Tutorial

Setting Up Your TypeScript Project

If you’ve decided to use TypeScript for your project, it’s important to set up your project correctly from the start. Doing so will help ensure a smooth and successful development experience. In this article, we will cover how to get started with a TypeScript project, from setting up your development environment to compiling your TypeScript code into JavaScript.

Installing TypeScript Compiler

To work with TypeScript, you will need the TypeScript compiler. The compiler will take your TypeScript code and turn it into plain JavaScript. You can install the compiler via npm by running the following command:

npm install -g typescript 

Creating Configuration File

The next step is to create a configuration file for your project. This is where you will be able to specify the compiler options to use. The configuration file can be named either tsconfig.json or tsconfig.js. For this example, we will be using the JSON format.

{
  "compilerOptions": {
    "target": “es6”,
    "module": “commonjs”,
    "outDir": “./build”
  }
}

Writing Your TypeScript Code

Now that your environment is set up, you can start writing your TypeScript code. You can either write the code directly in the .ts files or write them in the .js files and use the TypeScript compiler to convert them to .ts files.

Compiling Your TypeScript Code

Once your code is written, it’s time to compile it into JavaScript. To do this, you can use the tsc command which is provided by the TypeScript compiler. To compile your code, run the following command:

tsc --init

This command will read the configuration file and compile the code according to the options specified in the configuration file.

Conclusion

Setting up a TypeScript project can seem intimidating at first, but it’s actually quite simple. By following the steps outlined above, you can quickly get started with your project.
