How to compile typescript using npm command?

Question

Well I just wanted to know is there any command which will directly compile the typescript code and get the output. Right now, what i am doing is,every time when i make changes

Answer 1

This is based on solution proposed by @ThomasThiebaud. I had to modify it a little to make sure the files are built in dist/ before nodemon tries to start the server.

"scripts": {
    "clean": "rimraf dist",
    "build": "tsc",
    "watch:build": "tsc --watch",
    "watch:server": "nodemon './dist/index.js' --watch './dist'",
    "start": "npm-run-all clean build --parallel watch:build watch:server --print-label"
  },

You still need to run npm start to start the whole thing.
