Evan Czaplicki is building a new query language for Postgres and SQLite
The Rethinking Database Programming thread revealed that Evan Czaplicki, the creator of Elm, is building a new functional query language targeting PostgreSQL and SQLite. The HN thread is short but the signal is strong: Elm has a devoted following among builders who care about correctness and ergonomics, and Czaplicki has credibility in the 'make hard things approachable without sacrificing rigor' space.
The pattern: there's persistent frustration with SQL as a programming interface, especially for people coming from functional programming backgrounds. Multiple projects have tried to address this, but none with someone of Czaplicki's profile attached. The Elm approach to error messages and type safety translated well to frontend work; applying that thinking to database queries is a credible bet.
It's early and there's not much code to evaluate yet. But the combination of the author's reputation and the unsolved problem of SQL ergonomics makes this worth watching closely.
So what?
If you're building developer tooling or internal DSLs around database access, watch this project. It could define a new idiom for how functional-leaning teams interact with relational databases. If it gets adoption, the ecosystem effects on Postgres and SQLite tooling could be significant.
