This repository is simply a set of 2 NodeJS applications that are exposing two services: Customers and Invoices for a presentation I'm going to have soon. Video links will be posted once ready.
The idea is to show the audience how REST and a good API Gateway are perfect tools to make your APIs really resilient and ready to change.
Express-Gateway is the API Gateway choosen here; basically because it's open source and really spread among the community; and I work on it as fulltime job. However any other else will do the job; you might want to check Kong as well.
Docker is used as a way to simulate different network topologies.
- Start the system
By using Kubernetes or whatever you like
- Insert some fixtures
curl -u t:t -X POST http://localhost/customers -H "Content-Type: application/json" -d '{"name":"Porcesco", "surname":"Gerbone"}'
curl -u t:t -X POST http://localhost/customers -H "Content-Type: application/json" -d '{"name":"Vincenzo", "surname":"Chianese"}'Grab the returned ID and create some followup fake data
curl -u t:t -X POST http://localhost/customers/${customerId}/invoices -H "Content-Type: application/json" -d '{"date":"1507889426524", "amount":"150"}'
curl -u t:t -X POST http://localhost/customers/${customerId}/invoices -H "Content-Type: application/json" -d '{"date":"1507889426524", "amount":"200"}'Alternative: node client.js and fill in your data directly
- Have fun.
There's also a directory called kubernetes that contains a set of files to deploy the application and the dependencies
in any Kubernetes cluster. In that case, instead of localhost, you might need to enter the IP address assigned by
the cluster.
