Restart node upon changing a file

You should look at something like nodemon.

Nodemon will watch the files in the directory in which nodemon was started, and if they change, it will automatically restart your node application.

Example:

nodemon ./server.js localhost 8080

or simply

nodemon server

A good option is Node-supervisor:

npm install supervisor -g

and after migrating to the root of your application use the following

supervisor app.js

forever module has a concept of multiple node.js servers, and can start, restart, stop and list currently running servers. It can also watch for changing files and restart node as needed.

Install it if you don't have it already:

npm install forever -g

After installing it, call the forever command: use the -w flag to watch file for changes:

forever -w ./my-script.js

In addition, you can watch directory and ignore patterns:

forever --watch --watchDirectory ./path/to/dir --watchIgnore *.log ./start/file
