You can find the slides in the root of this project: slides-federation.html. Open in your browser to view.

These files are your starting point. We are going to build and compose a wonderful collection of services. Clone or download these files to get started.

After you have cloned the repo, simply checkout the Completed Solution branch to run the complete solution:

git checkout complete-solution

Then install the files:

npm install

This installer installs the files for each service, in every subfolder. Be patient.

npm start

Once the files are installed, npm start will start one instance of each service using pm2. You can only run one instance of each service because this course does not use a persistent data layer. It was designed to teach federation, not build your entire architecture. It stores data in memory, so if you spin up more than one instance of each service, you will see some wacky results.

The services should be running locally on the following ports. Please make sure you are not currently running any other applications locally on any of these ports:

You can also run the following npm commands:

Additionally pm2 commands work: pm2 flush, pm2 monit, etc.
