Solved: install typescript globally

Installing Typescript globally is a very important aspect for developers, especially those who frequently use Typescript for their projects. Typescript, a programming language developed and maintained by Microsoft, is a strict syntactical superset of JavaScript and adds optional static typing to the language. Typescript is designed for the development of large applications and compiles to JavaScript, offering the advantage of multi-paradigm programming, able to encapsulate the aspects of functional, imperative, and object-oriented languages.

How to Install Typescript Globally

To use Typescript in your projects, it needs to be installed on your computer system. The best approach is to install it globally.
There is only one step: You install Typescript globally using npm (node package manager). Npm is the package manager for the Node JavaScript platform.

First install Node.js and npm on your system. After that, you can install TypeScript using the npm command line tool. Follow these instructions:

//For npm users:
npm install -g typescript

//For yarn users:
yarn global add typescript

Understanding the Code

The “-g” flag in the npm install command installs Typescript globally on your system which means you can use it in any of your projects. Once Typescript is installed globally, you don’t have to install it separately for each of your projects.

After running this command and a successful installation, you can confirm if Typescript has been installed and verify its version using the command.

tsc -v

This command will return the Typescript version currently installed on your system, assuring a successful installation.

Benefiting Libraries and Functions

Installing Typescript globally also offers numerous benefits, and among them are libraries and functions. With Typescript installed globally, you don’t need to install it for each project and hence can save a lot of time.

Moreover, Typescript allows you to use features from the future today, functions, classes, modules, and interfaces – which are very helpful in writing robust code.

Typescript supports JS libraries and API documentation, provides code navigation, and autocompletes features which save a lot of time when programming. The features provided by Typescript make JavaScript code easier to read and understand.

  • Support for modern JavaScript: TypeScript also supports modern JavaScript features, such as modules, decorators, arrow functions, spread operators and destructuring.
  • TypeScript is optionally typed: JavaScript doesn’t provide a way to enforce types. This becomes a problem as the size of your codebase grows and/or when you’re collaborating with others.

By understanding the above details, developers can gain a clear idea on how to install Typescript globally, and make use of it for various project requirements efficiently.
