Nodejs and NPM on hypernode (to use gulp, sass, compass, less, grunt-cli etc)

Using the installed version of Nodejs
If you use the installed version, you can just start using
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 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:$PATH"' >> ~/.profile
Now every time you log in, the Bash shell is configured to look for tools in
Lets install some packages.
PATH is setup correctly, after the installation with
npm install, you should immediately be able to use the newly installed tool.
To find the latest command line tool installed, run:
ls -ltr /data/web/node_modules/.bin | tail -1
npm install gulp gulp-cli
npm install grunt grunt-cli
npm install sass
npm install compass
npm install less
You see the pattern here i presume? 🙂
yarn, a more recent version of nodejs is required, so follow the instructions and download and unpack a newer version of nodejs first
npm install yarn
Using a newer version of NodeJs
Install a newer version of Nodejs
If you want to use a more recent version, it is very easy to install the latest Nodejs yourself.
NodeJs offers precompiled packages on their website that are ready to use on your hypernode.
All we need to do is download and unpack them to make use of
npm and install your own node modules.
In this example we use version v4.4.5 but the installation process is the same when using older or newer versions.
- First, create the directory where we will unpack nodejs:
- Then, get the precompiled package from the NodeJS Website and unpack it in our directory:
wget https://nodejs.org/dist/v4.4.5/node-v4.4.5-linux-x64.tar.xz -O /tmp/node.txz cd ~/.node && tar xvfJ /tmp/node.txz -C . --strip-components=1 rm /tmp/node.txz
That’s it 🙂 you now have a precompiled node installation in
Configure a manually installed NodeJs
To run the manually installed executables, you need to change your
PATH variable to make sure your node is located by the Bash shell before the pre-installed version.
To do this, run the following command to add the locations to your PATH:
Or to make the settings permanent, add it to your
echo 'export PATH="/data/web/node_modules/.bin:/data/web/.node/bin:$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
- When using
npm search, so much memory is used that on start and grow nodes, your shell will get killed and you’ll be automagically logged out of your hypernode due to our out of memory protection.
