We need Node.js on the front-end mainly for making the developers’ work easier and for managing developer dependencies.

Tools We Will Install

  • Node.js – a javascript runner from the command line.
  • NPM – a javascript package manager.
  • Bower - a front-end package manager (e.g. jQuery or Bootstrap framework).
  • Grunt - an assembler or builder; a task runner for developers.
  • Grunt plugins – Grunt task plugins (e.g. for compiling preprocessors into CSS or files minification).

In time, you may take a fancy to Yeoman automators or other tools such as Gulp and WebPack. They are also based on Node.js, however, to make things simple, we will not deal with them just now.

Node.js

Now we will focus on the command line so it is good to know some basics. Here are guides for installing it on Windows and on Linux & Mac.

Node.js and NPM

NPM is a packaging system of Node.js. You have to download and install a complete version of Node.js.

Are You a Windows Guy? First Things First Then

  1. It is good to install Visual Studio Code. This is a code editor which also installs Node.js support for Windows.
  2. Then install Git using the command line. In the “Adjusting your PATH environment” step, choose “Run Git from the Windows Command Prompt”.

And now for everyone, regardless of the platform they use. Install Node.js globally. All the ways to do it are described here: nodejs.org/en/download/

Test if everything’s OK by using the command for displaying the NPM version:

npm -v

All other dependencies will be installed as Node packages.

Sometimes, it is recommended to run all NPM commands as an admin (sudo npm …). However, this is not good from a security point of view. It is much better to grant the current user privileges to write into usr/local:

sudo chown -R $USER /usr/local

That is the end of this “lecture about security”. Now, let’s install useful packages.

Grunt, Bower and Other Packages

Will you use a Grunt assembler? Then, using the command line, you will have to install a global package: grunt-cli:

npm install -g grunt-cli

And what about the front-end Bower packager? That’s easy. Just install it globally like this:

npm install -g bower

Using the very same procedure, you can install Grunt plugins, an alternative Gulp assembler and the Webpack.

Grunt Plugins

npm install <plugin-name> --save-dev

Notice that we do not install plugins globally, therefore we do not use the -g switch. And yes, Grunt plugins and Bower packages can be installed in any particular project. We really want to save them to the config files of the package manager (packages.json).

Are you using Windows? Then watch out! Some Grunt plugins require special attention. I know of PhantomJS, which is a dependency of the critical CSS (grunt-criticals) plugin or ImageMagick which is indispensable for plugins that deal with images, such as grunt-contrib-imagemin.

Bower Packages

bower install <plugin-name> --save

The --save-dev switch will save a plugin into developer dependencies. Beginners use it in connection with Grunt and its plugins. They can be installed using NPM.

If you want to install jQuery, it will be a user dependency. We will use the --save switch but for such dependencies, it is better to use Bower.

Cheatsheet for Packaging Systems

Fortunately, both Bower and NPM fortunately have similar commands:

# Searching a package in the central repository:
npm/bower search jquery-ui

# Displaying package details:
npm view jquery-ui
bower info jquery-ui

# Installing all packages on a project:
npm/bower install
# Installing a package and adding it to user dependencies:
npm/bower install jquery-ui --save
# Installing a package and adding it to developer dependencies:
npm/bower install jquery-ui --save-dev
# Installing a version specific package:
npm/bower install jquery-ui@1.11.x

# Updating all packages:
npm/bower update

# Listing a tree of dependencies:
npm/bower list
# Listing a tree of dependencies and a package version:
npm/bower list jquery-ui

# Removing a package:
npm/bower uninstall jquery-ui

# Deleting cache. Ideal when re-installing a package set:
npm cache clean

# Displaying packages that need to be updated:
npm outdated
bower list

# Help:
npm help
