Clustering

[alexbeletsky]

For me, what would make respawn even more nicer is not only support fork mode, but cluster mode as well. Something like,

var respawn = require('respawn');

var monitor = respawn(['node', 'server.js'], {
    env: {ENV_VAR:'test'},  
    cwd: '.',  
    mode: 'cluster',   // 'fork' or 'cluster' mode, 'fork' default
    instances: 2,      // int specifying number of cluster instances, 'max` default
    maxRestarts:10, 
    sleep:1000,
});

monitor.start(); // spawn and watch

I'm happy to contribute that feature if you think it's applicable and we can discuss some details :)

Would be nice indeed.

A quick question: I'm trying to use respawn to monitor a script "website.js".
But I would like to launch monitor.js (respawn) from a command start-stop-daemon

Seems not to work.

To be clearer:
if I do start-stop-daemon website.js => it works
if I do start-stop-daemon monitor.js (which monitor website.js) => it does not work.

How can i do?

Thanks for help :)

@alexbeletsky I've posted a pull request and you can use my fork npm install respawn-cluster right now.

Check out Revive it has cluster support and more features. It has a very similar api.

Mafintosh maybe we could figure a way to merge our code base. Or implement the cluster support features at least.
