Update Node.js with NVM and keep packages

Usually when new version of Node.js comes out and you update it by just installing new and removing old one, all of your global NPM packages are gone. Here is how to update to new version of Node and reinstall packages:

Install/update NVM first

For Windows, use nvm setup from "https://github.com/coreybutler/nvm-windows/releases".

Go to URL "https://github.com/creationix/nvm" and follow install/update instructions.

Third-party libraries

If you are installing the coturn package in Debian, Ubuntu or Mint, or if you installing the "turnserver" port in FreeBSD, or if you are installing one of the supplied binaries in the "downloads" section of the project, then the OS and the third party packages are installed automatically. The instrudctions below are for those who are setting the TURN server from scratch.

Before installing and configuring the TURN server, the latest stable libevent library should be downloaded, built and installed:

$ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz

As root, build and install the library with the usual:

$ tar xvfz libevent-2.0.21-stable.tar.gz
