Quill + Doobie = Better Together

The power of today’s Open Source libraries is integration, and the Cats ecosystem is a great case-in-point. Combining Http4s, fs2, and Doobie makes for a powerful recipe that is ridiculously easy to use. As of Doobie 0.7.0, Quill has joined the fray, bridging the gap to the database layer. You can now model your data layer, compose it into queries, transact it, and send it out to the world, without ever having to leave the functional paradigm. By creating this integration, both Doobie and Quill get more than the sum of their parts. Doobie for instance, leverages fs2 to get rich set of effect-level JDBC operations that support everything from parallel-streaming queries, to reactive monitoring of asynchronous events from database change-listeners. Typically, the SQL queries for these varying use-cases will be similar but also different in non-trivial ways. This is where Quill comes to the rescue, allowing the common parts of SQL-queries to be abstracted away from the uncommon parts, ensuring a very DRY and maintainable solution, especially when the queries get very, very big. Join us on the next step of this wonderful journey!
