Practical Microservices Workshop

More will come later, but for right now, this repo will verify that you can install and run what you need to for the workshop.

This workshop uses Node.js for the code and Docker for running databases.

Installation Instructions

Install Node.js v12.13.1
- If you're on MacOS or *nix, I recommend nvm
- If you're on Windows, I've heard good things about nvm-windows
Install Docker for your platform

Install Project Dependencies

From within the project folder, run npm install

Verify Installation

Run databases

docker-compose rm -sf
docker-compose up

Run verification script from this repo

nvm use
npm install
node script/verify-installation.js
Your results should look something like:

$ node script/verify-installation.js

Other Useful Software

A database viewer, such as TablePlus (https://tableplus.com/). It absolutely does not have to be this particular one, but you will benefit greatly from having something that will let you view the contents of the databases started in the docker-compose.yml file.

Verify You Can Access The Databases

There are 2 databases in docker-compose.yml. You can access them with the following connection params:

// Database 1 (SPOILER ALERT: we'll end up calling this the View Data database)
User: postgres
Host/Socket: 127.0.0.1
Port: 5432
Database: practical_microservices
Password: <It's blank.  As in literally blank.  Don't put all of this in there.>

// Database 2 (the Message Store database)
User: postgres
Host/Socket: 127.0.0.1
Port: 5433
Database: message_store
Password: <It's blank.  As in literally blank.  Don't put all of this in there.>

Obviously, if you don't use the provided Docker setup, then this connection info might not match what you have. It's up to you, but for the purposes of the workshop, we'll assume you are using the provided Docker setup.
