PostgREST – Serve a RESTful API from Any Postgres Database
You can use a library like https://github.com/agentultra/postgresql-replicant or similar to hook in a data plane and use PostgREST as a data plane.
Your business logic works on the event stream that comes from the WAL.

backend.sql and frontend.js = ♥
I wrote postgresql-replicant [0] in order to do this. It’s not a novel idea. It lets you read the logical replication stream.
On top of this library you can do all sorts of things: replicate data to Kafka or SQS, write a web socket server to publish changes to clients, etc.

Ask HN: What are some tools / libraries you built yourself?
https://github.com/agentultra/postgresql-replicant — stream delta changes from a PostgreSQL database. Not a novel concept or implementation but this library doesn’t exist in Haskell and that’s a shame because Haskell has lots of great libraries for working with streams.
https://github.com/agent ultra/DataVersion — type-directed data migration library. I needed to migrate some data in a document database that had no schema with years of data in it to a format that had a schema. I leveraged some other stuff to achieve it but this library was a key piece to being confident that the transformations were correct and complete. Migrated the database and backfill it with a Lambda function using this library.
Those are just the most recent ones.

Haskell good for general use?
On my stream at https://twitch.tv/agentultra I've been working on a library to stream changes out of a PostgreSQL database. We've had to figure out how to use low-level libpq bindings, concurrency primitives, serializing and deserializing binary messages, etc. You can find the library here: https://github.com/agentultra/postgresql-replicant
