Poke-Graph: Minimal Apollo Federation Demo

This project demonstrates a simple Apollo Federation setup using TypeScript and Node.js, with Pokémon card data and user management as subgraphs.

Structure

• cards-subgraph/: Serves Pokémon card data from a JSON file
• users-subgraph/: Manages users and their assigned cards
• gateway/: Federates the subgraphs into a single GraphQL endpoint

How it works

• Each subgraph is a standalone Node server exposing its own GraphQL schema
• The gateway composes both subgraphs into a single API
• All queries and mutations go through the gateway (http://localhost:4000/graphql)

Example Queries

See each subgraph's README for sample queries and mutations.

Getting Started

1. Install dependencies in each folder: npm install
2. Build each service: npm run build
3. Start each service: npm start
   • Start cards-subgraph and users-subgraph first, then the gateway
4. Open Apollo Sandbox/Playground at http://localhost:4000/graphql
