Environment building

First we need to install ts-node and typescript

Npm install-g ts-nodenpm install-g typescript

After the global installation is complete, you can test whether the installation is successful.

$ts-node-vv8.3.0$ tsc-vVersion 3.5.2

Let's print the version information separately.

Build application

Let's create a main.ts file that can be simpler.

Let str:string = "this is what is used for testing" console.log (str)

See if you can run the main.ts file directly

Ts-node main.ts

We can also add this command to the package.json file

"scripts": {"test": "echo\" Error: no test specified\ "& & exit 1", "start": "ts-node src/main.ts"}

This is what we just need to run

Npm run start

The result is the same as using the ts-node command directly.
