How do I execute typescript watch and running server at the same time?

node.js typescript npm command package.json

My idea is merge the commands as tsc -w & node app.js but I can't work the two commands at the same time. How do I do

You have a few options. Simplest is to use ts-node-dev : https://github.com/whitecolor/ts-node-dev

node.js typescript npm command package.json

Step 1

install concurrently, use npm or yarn

yarn add concurrently -D

create a script with this command

"scripts": {    "run": "tsc && concurrently \"tsc -w\" \"nodemon dist/app.js\"",}

run tsc first so that your directory has something at the time of running node

And with that you will have running your Typescript application 🚀

node.js typescript npm command package.json

Another option can be to use nodemon:

tsc -w & nodemon app.js

Since Typescript 3.4 the compilation is faster because you can use the incremental compiler option and they keep improving (including interesting changes for large projects in 3.8).
