A starting point for my series on schema federation

Schema Federation Demo

This is the project that accompanies my series on schema federation. For more information on schema federation or the reason for this project, read this post.

Each post after the first has a corresponding branch in this repo that acts as the starting point for that guide.

Running the services

Each service is defined by a single file that contains all of required information to have a functioning graphql API. To start, install the dependencies by running npm i in this directory and then run each node script in a separate terminal:

node ./auctionService.js

node ./photoService.js

These servers listen on ports 3000 and 3001 respectively.

Running the gateway

The correct method for running the gateway depends on the details of the example. For the first guide, you can start by downloading the appropriate binary from the latest release of the nautilus gateway and then pointing it at the two services that you just started:

gateway start --services http://localhost:3000,http://localhost:3001
