• Use nodemon to manage NodeJS instances. Install it by

sudo npm install nodemon -g

For NodeJS framework initiated by ExpressJS, just type “nodemon” to start the web app.

• Use forever to manage NodeJS instances. Install it by

sudo npm install forever -g

To start an Node instances:

forever start index.js

To restart all instances after a source update:

forever restartall

To list all instances:

forever list

To stop an instance:

forever stop 0

where 0 is the instance number.

For more info, consult

forever -h

• Problem: NodeJS cannot find modules. Solution: add the npm_noduels path to “NODE_PATH”, such as

NODE_PATH=C:\Users\[USERNAME]\AppData\Roaming\npm\node_modules

Similarly, on Linux:

export NODE_PATH=$NODE_PATH:/usr/local/lib/node_modules

for globally installed modules.

• Create a swap file on Linux VM to increase the swap size, and prevent “npm search” from crashing (out of memory). See tutorial here.
