Sample Code - Micro Frontends Reply

This is the example code copied by Manning book Micro Frontends in Action.

Local machine

Prerequisites

1. Clone this git repository or [download & extract the zip](https://github.com/tommyr22/micro-frontends-reply

2. Make sure you have Node.js (v12 or newer) installed.

   $ node -v
   v14.4.0
   

3. Go into the main directory and install all required dependencies.

   cd micro-frontends-reply
   npm install
   

Running the code

All examples involve starting up multiple applications which are owned by different teams. There is an NPM run for each directory. You can start examples like this: npm run [name_of_example].

The following command will start example #2:

npm run 02_iframe

The script starts all applications and shows a combined log output.
NOTE: Nginx stdout do not work on Windows.

It waits until the servers are ready and opens the example page in your default browser.

You can stop the example by hitting [CMD] + C in your terminal.

NOTE: The code should run on all platforms. However, if you're having troubles feel free to create an issue.

Folder structure and ports

Each example has its own folder (e.g. 02_iframe). Each example folder contains a subfolder that contains the actual application (e.g. cdn, decide, inspire).

Different port numbers are used to indicate ownership. This following table shows which teams owns which application. Make sure ports 3000 to 3003 are not allocated by another process on your machine.

Port	Team	Responsibility
3000	- shared -	infrastructure (web-server, app shell)
3001	Team Decide	product page
3002	Team Inspire	homepage, search, recommendations
3003	Team Checkout	cart, checkout process
