"A year with Hanami in production: the Good, the Bad and some Recipes"
summary
One year and a half of Hanami in production powers a REST API with 140 API actions and 400 Trailblazer operations, split into multiple apps and about 50 repositories across six databases (Postgres, Cassandra, Redis, Influx, ClickHouse, etc.). ROM.rb proves too limited so the stack switches to Sequel, keeping repositories as the single place for DB writes while returning Sequel models for reads. Auth starts with JWT then moves to JWE sessions; background jobs use RabbitMQ + Sneakers; WebSockets use AnyCable; Puma + hanami.boot serves production with ~300–400MB for 8 threads.
