Manager like PM2 for Dart?

[Robert Beyer]

Hi @all,

i have some nodejs application out there and i use pm2 to run the applications on the servers.

Is there a similar tool for dart apps?

greetings

AFAIK there's no tool out there, but I've seen somewhere using monit as a suggestion:

I found monit extremely counter-intuitive, so I usually just use crontab to start a script on startup.

In Dart, you can wrap your application entry point in its own zone (using "runZoned"), and catch all uncaught errors, without having

the application crash:

I have a very basic implementation of something like PM2. Emphasis on basic. I also have stopped updating it, and don't even use it:

If you find it attractive though, please consider contributing, and we can work it into a real solution for future users...

To anyone coming by this in more recent times:

PM2 now supports running programs in other languages. Specifically you can run a shell script with `PM2 start app.sh --interpreter=sh`

However I am compiling my code using dart2native and you can also just call `PM2 start ./app` if you have a native binary.

Shout out to Tobe for Angel as well!

sorry it should read `PM2 start app.sh --interpreter=bash`
