In this article, we would like to show how to install TypeScript compiler under Windows.

Quick solution:

npm install -g typescript

Note: after typescript package installation, you can use tsc command.

 

1. Installation instruction

  1. Ensure that NodeJS and npm are installed (installation and running instruction is here).
  2. Open some terminal as administrator, e.g. Bash (an installation instruction is here).
  3. Install TypeScript compiler with the command:
    npm install -g typescript
    where -g flag means global installation.
    Output:
    john@DESKTOP-PC MINGW64 ~
    $ npm -g install typescript
    C:\Users\john\AppData\Roaming\npm\tsc -> C:\Users\john\AppData\Roaming\npm\node_modules\typescript\bin\tsc
    C:\Users\john\AppData\Roaming\npm\tsserver -> C:\Users\john\AppData\Roaming\npm\node_modules\typescript\bin\tsserver
    + typescript@4.0.3
    updated 1 package in 17.571s

2. *.ts compilation instruction

  1. Create Script.ts file:
    for(let i = 0; i < 5; ++i) {
        console.log('Hello world!');
    }
  2. Run tsc command
    tsc Script.ts

    Note: after compliation Script.js file should be created.

  3. Run compiled program
    node Script.js

    Output:

    Hello world!
    Hello world!
    Hello world!
    Hello world!
    Hello world!
