NodeJS-让我的应用程序永远运行

Question

Currently, I have a NodeJS service running on my server. It provides a RestAPI thanks to HAPI.JS

This service run permanently with forever executed in upstart script but I got some trouble.

Sometimes, the service have an error like this :

Debug: internal, implementation, error 
    TypeError: Uncaught error: Cannot call method 'replace' of undefined....

At this moment, server is completly down and never restart :(

I need a 100% stable service that why I have to restart it when an error appears.

My Question :

How can I restart NodeJS Service with forever when errors occured ?

Answer 1

Run you app with pm2 instead of forever. Pm2 will restart the node server even after uncaught exceptions.

Answer 2

If the process fails on startup then it won't restart automatically. You can configure the minimum uptime --minUptime flag.

You can then use the --watch flag to watch for changes of the fix.

However, the specific error you're receiving wouldn't normally stop the Hapi process which would suggest this isn't a forever issue.
