NodeJS server doesn't start with pm2

Question

When I'm trying to start my nodeJS-server with pm2 it stops or returns an error.

Here's the relevant package.json file:

"scripts": {
"start": "nodemon --watch '**/*.ts' --exec ts-node index.ts",
"bundle-colyseus-client": "browserify ./node_modules/colyseus.js/lib/index.js -s Colyseus -o static/colyseus.js",
"build": "npm run bundle-colyseus-client",
"heroku-postbuild": "npm run build"}

I tried the following commands to start the server:

• pm2 start npm -- start STOP
• pm2 start index.ts ERROR

Answer 1

you trying to run ts file with ts-node. try to install typescript in pm2

pm2 install typescript

and then the second command

pm2 start index.ts

Answer 2

您的服务器可能正在与nodemon一起运行，我想首先通过从nodemon退出来停止服务器，然后启动pm2，然后它应该可以工作

Answer 3

If you're using PM2 as a module, the documentation says to add the following script on your package.json start script:

"scripts": {
    "start": "pm2-runtime start ecosystem.config.js --env production"
},

Now you can restart your application.
