Developing NodeJS apps using AngularJS 4 in macOS

Well, that is one long title for a blog post! but, bare with me I’m going straight to the point. Recently I’ve been wanting to dip my toes in the AngularJS 4 world and to make it more exciting I thought maybe I will do it on a Mac using NodeJS and VSCode. Now that VSCode is getting more and more popular sharing my experience here might actually help someone and a future me to have an easier ride than mine today.

The ingredients

  • A computer with macOS on it. Any version would do.
  • Homebrew
  • VSCode
  • Git client for Mac
  • NodeJS
  • Half an hour of time!

Preparation

We first need to get the environment ready before we start to develop something and believe it or not there are several ways you can do that. After studying and trying out different ways, this is the best way I found that is the safest, fastest, easiest, most repeatable and undoable, and yet inline with best practices of Apple in Mac world!

  1. Install Homebrew if you don’t already have it.
  2. Install NPM
  3. Install VSCode or any other code editor / IDE
  4. Install Git client
  5. Install NodeJS
  6. Make a folder
  7. Start VSCode

1. Install Homebrew

Although NodeJS website provides an installer for NPM,  I suggest using Homebrew to install NPM and any other open source package you might need in you Mac. NPM installer needs admin rights and it will put files in folders that only admin users have access to. You don’t want any 3rd party application tinkering with those areas do you?! plus it will be easier to cleanup afterwards should you need to remove NPM for some reason in future.

I recommend you visit Homebrew’s official website https://brew.sh to know more about it. At the time of writing this blog post, you just need to open Terminal and run the following command to execute Homebrew’s installation script. The script will explain what it does and then pauses for your confirmation.


ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install NPM

Now that you have installed Homebrew, installing NPM is as simple as typing the following command in the Terminal window. It will install the latest stable version.


brew install node

After the installation is done, you can type the following command to see which version is installed.


node -v

If you need to update Node and NPM in future you can use brew upgrade node and to uninstall them you can use brew uninstall node.

3. Install Visual Studio Code

This step is pretty easy. You just need to download and install Visual Studio Code, Microsoft’s lightweight code editor from its official website and install it like any other application. Here is the official download page: https://code.visualstudio.com/download

Directions

There are two ways you can start to write a new application by AngularJS. You can either manually set up the project by creating the required boilerplate files and writing configurations which can really help you understand what is going on behind the scene or you can use the Angular CLI to do it for you and this way you save some time. I’m going to explain both methods here and first I am going to start with the manual method. Instead of explaining the manual method, I’m going to show you how to use Angular CLI because that’s the way you’re most probably going to do it in future. Then I will explain all the files and configurations in such a way that you can even do it manually if you wish to.
