Auto restart apps on file change
PM2 can automatically restart your application when a file is modified in the current directory or its subdirectories:
pm2 start app.js --watch
If --watch
is enabled, stopping it won’t stop watching:
pm2 stop 0
will not stop watchingpm2 stop 0 --watch
will stop watching
Restart with --watch
will toggle the watch
parameter.
To watch specific paths, please use a Ecosystem File, watch
can take a string or an array of paths. Default is true
:
module.exports = {
apps: [{
script: "app.js",
watch: ["server", "client"],
// Delay between restart
watch_delay: 1000,
ignore_watch : ["node_modules", "client/img"],
watch_options: {
"followSymlinks": false
}
}]
}

watch_options
is an object that will replace options given to chokidar. Please refer to chokidar documentation for the definition.
