Update 18-08-2016: We decided to pre-install Node.js on all Hypernodes due to growing demand. You can still choose to install the most recent version by downloading the preinstalled version from the Node.js website, just be aware a Node.js installation is present on the Hypernode itself already.

Using the Installed Version of Node.js
If you use the installed version, you can just start using node and npm.
Setting your PATH
If you want to execute the tools that you installed using npm, you should make sure these executables can be located by the shell. This can be easily done this by adjusting your PATH setting.
This PATH variable is used by the Bash shell to locate binaries and scripts. You can adjust it by exporting the PATH variable:
If you want this setting to be configured every time you log in to your Hypernode, you can add this setting to your ~/.profile, this file is loaded every time a new shell is spawned.
To configure your PATH variable at login time, run the following command:
echo 'export PATH="/data/web/node_modules/.bin:$PATH"' >> ~/.profile
Now every time you log in, the Bash shell is configured to look for tools in /data/web/node_modules/.bin and /data/web/.node/bin.
Lets install some packages.
When your PATH is setup correctly, after the installation with npm install, you should immediately be able to use the newly installed tool.
To find the latest command line tool installed, run: ls -ltr /data/web/node_modules/.bin | tail -1
npm install gulp gulp-cli
npm install grunt grunt-cli
npm install sass
npm install compass
When your Hypernode is using the OS Debian Buster then the aforementioned method will not be applicable. Instead you can use the following command to install compass
gem install --user-install compass
Next you need to set the correct path so you don't have to type the absolute path to access compass each time. You can do s with the command:
npm install less
You see the pattern here i presume? ?
To install yarn, a more recent version of nodejs is required, so follow the instructions and download and unpack a newer version of nodejs first
npm install Yarn
Using a newer version of Node.js
Install a newer version of Node.js
If you want to use a more recent version, it is very easy to install the latest version of Node.js yourself.
NodeJs offers precompiled packages on their website that are ready to use on your Hypernode.
All we need to do is download and unpack them to make use of node and npm and install your own node modules.
In this example we use version v4.4.5 but the installation process is the same when using older or newer versions.
- First, create the directory where we will unpack Node.js:
- • Then, get the precompiled package from the Node.js website and unpack it in our directory:
wget https://nodejs.org/dist/v4.4.5/node-v4.4.5-linux-x64.tar.xz -O /tmp/node.txz cd ~/.node && tar xvfJ /tmp/node.txz -C . --strip-components=1 rm /tmp/node.txz
That’s it ? you now have a precompiled node installation in ~/node
Configure a Manually Installed Node.js
To run the manually installed executables, you need to change your PATH variable to make sure your node is located by the Bash shell before the pre-installed version.
To do this, run the following command to add the locations to your PATH:
Or to make the settings permanent, add it to your ~/.profile:
echo 'export PATH="/data/web/node_modules/.bin:/data/web/.node/bin:$PATH"' >> ~/.profile
Both the installations (the already installed or the precompiled self-downloaded version) use /data/web/node_modules as their location to install new packages to when using npm.
- When using npm search, so much memory is used that on Hypernode Start and Grow plans, your shell will get killed and you’ll be automagically logged out of your Hypernode due to our out of memory protection.
