How to run typescript compiler as a package.json script without grunt or gulp

Question

I don't want to use grunt or gulp to compile ts files. I just want to do it in my package.json something like this:

  "scripts": {     "build": "tsc main.ts dist/"   }, 

is it possible?

Answer 1

"build": "tsc main.ts dist/"

Highly recommend you use tsconfig.json and then the -p compiler option to build your code. Look at: Compilation-Context

Setup

Here is the setup for using tsc with NPM scripts

init

npm init npm install typescript --save 

And then in your package.json add some scripts:

"scripts": {     "build": "tsc -p .",     "start": "npm run build -- -w" }, 

Use

• For build only: npm run build
• For building + live watching : npm start

Enjoy 🌹

Answer 2

If you want to compile and run, you can use the ts-node module.

npm install --save-dev ts-node  npm install --save-dev typescript 

And run with:

"scripts": {     "start": "ts-node index.ts" }, 

All other typescripts files that index.ts has imported (along with imports from index.ts dependencies) will be compiled and executed.
