TypeScript Installation

Learn how to effortlessly set up TypeScript in your development environment. This in-depth guide covers various installation methods, including npm, catering to different project needs. Discover the best approach for your workflow and start building robust TypeScript applications today.

TypeScript Installation Methods

Using npm (Node Package Manager)

Prerequisite: Node.js installed on your system.

Global Installation (for use in any project)
Syntax

npm install -g typescript

This installs TypeScript globally, allowing you to use the TypeScript compiler (`tsc`) in any project.

Local Project Installation (as a development dependency)
Syntax

npm install typescript --save-dev

This installs TypeScript locally to your project, listed as a development dependency in your project's `package.json`.

Using NuGet Package (for .NET/Core Projects)

  1. Open the NuGet Package Manager in your project (right-click project > Manage NuGet Packages...).
  2. Search for Microsoft.TypeScript.MSBuild and install it.

This adds an MSBuild task that automatically compiles TypeScript files based on `tsconfig.json` configuration during project builds.

Using IDE Plugins

IDE-specific plugins provide integration and features for TypeScript development. Popular examples include:

  • Atom: Atom-TypeScript
  • Eclipse: TypeScript IDE for Eclipse or TypeScript Plug-in for Eclipse
  • Visual Studio: TypeScript Visual Studio Extension (for older versions)
  • WebStorm: TypeScript support built-in

Verification and Testing

Global Installation

Syntax

tsc -v  # Check installed TypeScript version

Use this command to check the installed TypeScript version globally.

Local Project Installation

Check your project's package.json file for the installed version.

IDE Plugins

Refer to your IDE's documentation for verification and testing instructions.

Additional Resources

TypeScript Playground: https://www.typescriptlang.org/play

Experiment with TypeScript code online without installation.

Choosing the Right Method

  • For simple projects or prototyping, using the online playground or npm's local project installation is ideal.
  • For .NET projects, NuGet package installation is recommended.
  • For enhanced development experience within specific IDEs, consider installing plugins.
