As a dependable expert in the tech industry, we understand the necessity of keeping up with the latest technologies and software. Today, we’ll be focusing on TypeScript, a powerful open-source language developed by Microsoft. This article will provide a thorough walkthrough on how to install TypeScript on Ubuntu 22.04 LTS.

What is TypeScript?

TypeScript, an open-source language created by Microsoft, is designed specifically for building large-scale web applications. It enhances JavaScript by introducing features such as static typing, which leads to fewer runtime errors, improved code quality, and easier maintenance, particularly in large-scale projects.

Note: TypeScript isn’t a competitor to JavaScript but complements it by providing additional features that make JavaScript better. It supports existing JavaScript code, allows the integration of popular JavaScript libraries, and facilitates calling TypeScript code from native JavaScript.

Step 1: Update Your Ubuntu System

The first step in any installation process on a Linux system is to make sure that the system is up-to-date. Regular updates are important for maintaining system security and compatibility. They provide the latest features and bug fixes, enhancing system performance and stability.

sudo apt update
sudo apt upgrade

Step 2: Install Node.js

Node.js is a crucial component in setting up a TypeScript development environment. To install Node.js, use the following command:

sudo apt install nodejs npm

After installation, it’s always a good idea to verify the version of Node.js installed. This verification step ensures that the installation was successful and that Node.js is ready for use.

node --version

Step 3: Install TypeScript on Ubuntu 22.04

Once Node.js is set up, you can proceed to install the TypeScript compiler.

npm install -g typescript

The -g flag installs TypeScript globally, making it available across your system. After installing TypeScript, it’s important to verify the installation.

tsc --version

Step 4: Create a TypeScript Test Project

After installing TypeScript, you can create a test project to verify that everything is working correctly. Now generate a package.json file for your project. This file holds various metadata relevant to the project.

npm init

Install TypeScript in your project:

npm install typescript ts-node

Install the Node.js type declaration file. This provides TypeScript with the shape of the library’s exported API:

npm install @types/node

Generate a tsconfig.json file. This file specifies the root files and the compiler options required to compile the project:

npx tsc --init --module commonjs

Congratulations! You have successfully installed TypeScript.
