ts-runner

Run TypeScript files directly without (manually) transpiling them to JavaScript.

ts-runner requires nodejs.

Preparation

Clone repo and set ts-runner executable

git clone https://github.com/tinosteinort/ts-runner
cd ts-runner
chmod +x ts-runner

Define the interpreter of the file

ts-runner is used as interpreter for the TypeScript file, so it must be referenced in the first line of the file. If the target script file is in the same directory as the ts-runner, it is enough to add

#!ts-runner

If ts-runner is in your home folder you can add

#!~/ts-runner

If ts-runner is on the $PATH you can add

#!/usr/bin/env ts-runner

... and so on...

Example

Create file examplescript.ts and add the following content:

#!ts-runner

const value: string = 'World';
console.log('Hello', value);

Set the script file executable:

chmod +x examplescript.ts

Now, you are able to execute the script. Type in the terminal:

./examplescript.ts

Alternatives

There are other tools, that do the same: see ts-node
