change code on runtime without restart

[Leandro Müller]

Hi everyone.

How can I change source without restart server?

I read about nodemon  but it restart server when there is any change.

I need to change my application on runtime 24/7.

Thanks.

How I do this is have a "runner.js" which uses cluster. When it receives SIGUSR2 it restarts each child process one-by-one, ensuring that the service is always running even during a restart.

Hi,

I haven't work with these modules but maybe they suit your needs:

Btw, seems to be an interesting topic I'll follow up.

Thanks

pm2 offers a "rolling restart" of its processes.
