pm2 can't start script with :

Question

I want to start my script with pm2 in Windows, but I get the error: SyntaxError: Unexpected token ':'

my start script is start:dev and to run that I say: pm2 start npm -- 'start:dev'

my script:

"scripts": {
    "start": "NODE_ENV=production node dist/src/index.js",
    "build": "tsc -p . && ncp productionenv ./dist/src/.env",
    "start:dev": "npm run build:dev",
    "build:dev": "nodemon src/index.ts --exec ts-node src/index.ts -e ts,graphql",
    "test": "jest"
  },

Full err:

@salman did exactly what they said `pm2 start npm --name "gateway" -- run "start:dev"` and still getting same error — Mj Ebrahimzadeh, Feb 23 '22 at 09:46
i have used the same command and its working fine, check you package.json file if you have that script or not? — salman, Feb 23 '22 at 10:12

You can use following way to run the script :

pm2 start npm --name "your-app-name" -- run "start:dev"

You are actually running the custom script, so it needs to be run in a different way:

pm2 start npm run start:dev

Whenever you add any custom script npm run scriptname is the command to follow. If you want to know more about it, check here.

Also, it should be a part of the script:

"scripts": {
    "start": "NODE_ENV=development npm start",
    "start:dev": "npm start --watch",
    "start:debug": "npm start --debug --watch",
    "start:prod": "node dist/main",
  },

I ran your script and got this error ` Script not found: C:\Users\xx\Desktop\xx\xx\back\xx\gateway\run` – Mj Ebrahimzadeh Feb 23 '22 at 09:58

The error is with the gateway that you are adding as a part of the command. I wanted to see the package.json file and how are you running the command. – Apoorva Chikara Feb 23 '22 at 10:03

It seems you have something wrong with the command itself. – Apoorva Chikara Feb 23 '22 at 10:04
I have added my package.json script. Without pm2 I use `yarn start:dev` – Mj Ebrahimzadeh Feb 23 '22 at 10:30

I don't see `pm2`, why don't you directly run `npm run build:dev`? Also, it seems the nodemon is not installed properly. There is something that is causing the issue and you have to add it here so that I can help you. – Apoorva Chikara Feb 23 '22 at 10:36
I have 9 subgraphs and want to use pm2 to restart all at the same time when needed – Mj Ebrahimzadeh Feb 23 '22 at 10:38
Can you add more details to the error as it is difficult now to make any comments without more information? – Apoorva Chikara Feb 23 '22 at 10:42

Only for who run NextJs.

should create deploy.json file:

{
    "apps": [
        {
            "name": "dicom-interactive",
            "script": "./node_modules/next/dist/bin/next",
            "args": "start",
            "env": {
                "PORT": "3000",
            }
        }
    ]
}

run

pm2 start deploy.json
