open source self-hostable Farcaster Graphql API

Charon is an open-source set of Docker Compose extensions that adds PostgreSQL storage, Redis caching, and a GraphQL API to a base Snapchain node, which is a Farcaster Hub deployment managed by the snapchain.sh installer. PostGraphile auto-generates the GraphQL API from the PostgreSQL schema and serves a GraphiQL interface on port 5000. Waypoint, a Farcaster Hub API client, subscribes to hub events and stores them in PostgreSQL, while optional backfill workers populate historical data. The stated requirements are at least 8GB of RAM (16GB recommended) and 100GB or more of disk space for the database.
