I'm confused, I Can run 2 project in 2 terminal in windows then why should I choose pm2?, I need run 2 project in one terminal or 1 server like heroku, Can I do That with pm2? do you have an example?

@papakai

@saeedhei you might try out cross-env NODE_ENV=development nodemon --exec 'node --require @babel/register' src/index1.js" && cross-env NODE_ENV=development nodemon --exec 'node --require @babel/register' src/index2.js"

but i am really not sure if a) this works or b) it does what you want

it will also not execute 2nd script if 1st one fails

I will want to run 2 telegram bot , Thanks, I will Check That.

Kai Schwarz

@papakai

alternative: realize a nodejs script that handles both telegram bot instances, then you are fine

Is it possible to start a rails server with pm2?

In my ecosystem.config.js I've got something like:

{
      name: 'rails-api',
      script: 'bundle exec rails s -p 3001 -b 0.0.0.0',
      cwd: './api',
      interpreter: 'bash',
     ...
}

I've tried using bash and also setting interpreter to none and running the binary ./api/bin/rails

I tries installing typescript with pm2 pm2 install typescript and it didn't work. Can anyoane suggest something, please?

I notice the part : Serve static file over HTTP.

I use the command: pm2 serve ./dist/ 8080, and it be valid just for the SPA page (for the root index.html file, http://localhost:8080/).

But I would like that it could also for other html files (like http://localhost:8080/other.html or http://localhost:8080/me/about.html). It just like a Nginx (a server engine ).

The PM2 can do that ? and how should I do?

I think it will be very convenient to developers. ( just for development)

Hi everyone!

Does somebody know where I can find modules installed by pm2 install [module]?

@dsathyakumar

Hi I'm trying a use-case to be able to communicate between PM2 workers. There are some examples listed here:

Most of these examples use the sendDataToProcessId method

But then, the official docs:
https://pm2.keymetrics.io/docs/usage/pm2-api/#send-message-to-process

uses something called launchBus.
I could not find any further docs or usecases listed for launchBus

Could someone please elaborate on the purpose of launchBus and why does it need to be used along with sendDataToProcessId ?

Hi, did anyone ever run into this issue:

Basically, it says that it can't find the ecosystem file that it must have found, because "appname" is from the file.
This is inside a docker container as you might have guessed from the hostname.
