How to backup my Node.js setup when upgrading

I want to upgrade Node.js on Ubuntu, but I want to make sure that if anything goes wrong I could revert back my source code, installed modules and node binary to the working setup. How to achieve that?

You can install any version of node.js just go to downloads. Go into Other Releases and download what version you want with respect to your OS and 32-bit or 64-bit. Example:

  • node-vX.XX.X-OS-x64.tar.gz (64-bit)
  • node-vX.XX.X-OS-x86.tar.gz (32-bit)

Then, follow the instruction on the github.com. Building and installing Node.js

Another way is to use NVM, the Node Version Manager (it works in a very similar way to rvm for ruby). This allows to install and manage multiple versions of node. Here's a snippet (source):

Usage:
nvm install <version>       Download and install a <version>
nvm use <version>           Modify PATH to use <version>
nvm ls                      List versions (installed versions are blue)

You can also check this n. A Simple flavour of node binary management.

Update (as per comments):
If you have installed the nvm after node.js. You can check already installed by using nvm ls which lists already installed version(s) ready to use.

amolkulkarni@ubuntu:~$ nvm ls
current: v0.10.18
