Installing and Configuring TypeScript

In this tutorial, we'll walk through how to install and configure TypeScript so you can start developing efficiently.

Prerequisites

Before you begin, make sure you have:

• Node.js installed (version 14 or higher)
• npm or yarn as a package manager
• A code editor (VS Code recommended)

Check Node.js

node --version
npm --version

Installing TypeScript

1. Global installation (recommended for beginners)

# With npm
npm install -g typescript

# With yarn
yarn global add typescript

2. Verify the installation

tsc --version

You should see something like: Version 5.3.3

Creating Your First TypeScript Project

1. Create a new folder

mkdir mon-projet-typescript
cd mon-projet-typescript

2. Initialize the project

# Initialize npm
npm init -y

# Install TypeScript locally (recommended for projects)
npm install -D typescript

# Install Node.js types (if needed)
npm install -D @types/node

3. Create the configuration file

# Generate tsconfig.json
npx tsc --init
