Not able to run typescript node.js app with ts-node with pm2

Question

I have created a basic node app with typescript top of it. I am using ts-node to do so and it's working totally fine with nodemon. But I need to move it to the server now I am stuck. PM2 is showing error all the time. I have gone through GitHub and other answers on StackOverflow. Nothing helped me here. please help.

I have tried installing typescript and ts-node with PM2. But It did not work for me. I also have tried running file directly, not worked. I am clueless now how should I fix this.

 "scripts": {
    "start": "nodemon -x ts-node src/server.ts"
  },

It works fine with simple npm run start command

madbo@DESKTOP-CS5UFKE MINGW64 /e/shailesh/nodejs/NodeType
$ npm run start

> NodeType@1.0.0 start E:\shailesh\nodejs\NodeType
> nodemon -x ts-node src/server.ts

[nodemon] 1.18.5
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `ts-node src/server.ts`
24 Mar 22:33:23 - listening on port 3000
Mongoose default connection is open to  mongodb://localhost:27017/todo 😍

What I have tried so far that didn't work *( PM2 is globally installed) *

pm2 start ts-node -- --type-check -r tsconfig-paths/register src/server.ts

It gave me this error

madbo@DESKTOP-CS5UFKE MINGW64 /e/shailesh/nodejs/NodeType
$ pm2 start ts-node -- --type-check -r tsconfig-paths/register src/server.ts
[PM2][ERROR] script not found : E:\shailesh\nodejs\NodeType\ts-node

I have also used the following

pm2 start npm  -- ts-node src/server.ts

and got

$ pm2 start npm  -- ts-node src/server.ts

Answer 1

It's very simple guys.

Just use tsc and pm2 watch combination with single & to run both commands.

"scripts": {
    "serve": "tsc src/app.ts -w & pm2 start dist/app.js --watch"
},

Answer 2

Step 1

create a file run-ts.sh with

ts-node -T index.ts

Step 2

run this command

pm2 start run-ts.sh

And with that you will have running your Typescript application 🚀
