How to watch and reload ts-node when TypeScript files change

Question

I\'m trying to run a dev server with TypeScript and an Angular application without transpiling ts files every time. I found that I can do the running with ts-node

Answer 1

Here's an alternative to the HeberLZ's answer, using npm scripts.

My package.json:

  "scripts": {
    "watch": "nodemon -e ts -w ./src -x npm run watch:serve",
    "watch:serve": "ts-node --inspect src/index.ts"
  },

• -e flag sets the extenstions to look for,
• -w sets the watched directory,
• -x executes the script.

--inspect in the watch:serve script is actually a node.js flag, it just enables debugging protocol.
