This repo provides a demonstration supergraph for a media business containing media and users subgraphs. You can explore the schema and run queries against it in Apollo Studio. We encourage you to also use the schema as inspiration for your own media supergraph!

In order to get started, you must first install all required packages and ensure you are running the following versions:

Router version v1.22.0
Federation v2.4
Apollo Server v4
node v20

Once you have checked each of these versions, then install all dependencies:

npm i

locally run Subgraphs:

npm run dev

locally run Router:

npm run router

Locally run the subscriptions subgraph

npm run subscriptions

NOTE: If this is your first time running the project, make sure you have first downloaded the latest version of Router (v1.22.0+ for Subscriptiona support) using the following command:

curl -sSL https://router.apollo.dev/download/nix/latest | sh

This demo is published to the Apollo Solutions organization in Apollo Studio with the graph ID apollo-media-supergraph.

You can also view and share the public variant to run queries right from Explorer.

If you would like to run some sample operations, checkout the public Operation Collections in Explorer.

We also have a series of blog posts on media best practices that dive into different elements of this schema to illustrate how Apollo GraphOS helps power essential features of modern media applications:

• Blogs currently in progress

Below is the list of GraphOS Specific features that are demonstrated in this repo:

• @Defer
• Subscriptions
• Entity Interface

This repo runs a monolithic express server for all subgraphs purely for demo purposes. However, in order to suport subscriptions we need to support web sockets from Router to Subgraph. Therefore we run a separate subgrpah server for the trending subgraph to demonstrate this feature.

You can actually curl this Subscriptions endpoint via Router as well via the following:

curl 'http://localhost:4000/' -v \
  -H 'accept: multipart/mixed; boundary="graphql"; subscriptionSpec=1.0, application/json' \
  -H 'content-type: application/json' \
  --data-raw '{"query":"subscription TrendingMedia { trendingMedia { id }}","operationName":"TrendingMedia"}'

If you want to run this supergraph locally you can clone this GitHub repo and follow the instructions in DEV.md.

The code in this repository is experimental and has been provided for reference purposes only. Community feedback is welcome but this project may not be supported in the same way that repositories in the official Apollo GraphQL GitHub organization are. If you need help you can file an issue on this repository, contact Apollo to talk to an expert, or create a ticket directly in Apollo Studio.
