demux-postgres

Action handler implementation for demux-js, providing Postgres database integration for blockchain event processing. Current stable version 4.0.1, maintained as part of EOSIO demux ecosystem. Releases are infrequent, with v4 focusing on TypeScript and updated demux peer dependency. Key differentiator: directly maps blockchain actions to Postgres state updates via SQL statements, offering persistence and queryability compared to in-memory handlers.
