This squid indexer presents its data using PostGraphile instead of the GraphQL server from Squid SDK. It gets the raw data from Subsquid Network.
Dependencies: Node.js v16 or newer, Git, Docker.
The only major difference between a squid PostGraphile API and any other PostGraphile API is the _squidStatus query. Here it is implemented via ProcessorStatusPlugin. See src/api.ts for details.
