What can we do to run a TypeScript file from the Command line?

Solution 1: Launch node filename.js to run the created js file

TypeScript will create a js file with the same name at runtime when you execute tsc filename.ts. Launch node filename.js to run the created js file.

The creation of a TypeScript file named helloworld.ts and some content. To launch helloworld.ts, run the commands shown below.

tsc helloworld.ts
node helloworld.js

It will give you the result: 

hello world from typescript file

Solution 2: Utilize the ts-node package

You also can utilize the ts-node package to run a TypeScript file from the Command line.

First, run the following command to install the ts-node package with npm or any other package managers.

npm install -g ts-node

Then, run the TypeScript files with this command:

ts-node filename.ts

Please run the following command to execute the same file that we attempted in solution 1.

ts-node helloworld.ts

It will give you the result:

hello world from typescript file

Solution 3: Combine both commands with a pole | and &&

You also can execute a TypeScript file from the command line by combining both commands with a pole | and &&, as shown below:

For Linux or MacOS:

tsc helloWorld.ts && node helloWorld.js

For Windows:

tsc greet.ts | node greet.js
