If you're like me you create scripts to automate things all the time. While you can do quite a bit withbash, it's just a lot easier to use your primary language--in this case TypeScript. With just a few tricks you can start writing your scripts in TypeScript.
Setup your Environment
First you need to get your environment setup. I'm going to assume you already have node and npm installed and your globally installed packages are in your path. Once you have that setup, globally install ts-node.
npm i -g ts-node
Create the Script
If you've made it this far then it's time to create your script. The only magic that's required is the first line needs to be a shebang statement.
#!/usr/bin/env ts-node
This tells bash that it should use ts-node to execute the contents of the file. Here's my sample script.
#!/usr/bin/env ts-node
function test(message: string) {
console.info(message);
}
test("Hello TypeScript!");
Now mark the script as executable.
chmod +x ./test.ts
And now you can directly execute your typescript file!
