JarCastingzio-jooq
Already using jOOq to run queries against your database from Scala? Quickly integrate existing code into your new ZIO App using zio-jooq.
This lib essentially helps you quickly wrap ZIO's effectBlocking() around everything that is called on a DSLContext.
Usage
val zDb = ZDb.fromDslContext(ctxt)
// alternatively:
zDb = ZDb.fromDataSource(...)
zDb = ZDb.fromConnection(...)
zDb = ZDb.singleConnection(...)
zDb = ZDb.pooledConnections(...)
for {
r1 <- zDb.of(_.select(field).from(table).fetch())
} yield r1
The artifact coordinates are:
libraryDependencies += "ch.j3t" %% "zio-jooq" % version

Connection Pooling
You will need the hikariCp jars on the classpath if you intend to use the pooledConnections variants: zio-jooq is built against version 3.4.5
About
This is an admittedly (very) thin wrapper around jOOq to let it work with ZIO. While it originates in a desire to learn more about ZIO, it also serves a real purpose in some codebases that rely on jOOq and are integrating ZIO.
Please note that it is a work in progress.
Disclaimer
This project stems from a particular way of using jOOq: if your use case is not covered, you're welcome to implement it or fill an issue.
Additionally, I'm still pretty new to ZIO, so this library might not be the most idiomatic. Here again, comments are more than welcome.
Considerations
Why not directly use something like Doobie?
There are two reasons why Doobie is not involved here:
- I only recently discovered that library, and don't know enough of it to make something useful out of it
zio-jooqis about letting you reuse as much as possible of the code you already have in a more ZIO'ish way.
It's a bit early at this point to work on replacing Jooq's JDBC plumbing with Doobie, though it's a thought that is worth entertaining.
This looks like a super small lib...
Yes, it is! Honestly, it's probably better to copy paste it than to rely on it via traditional dependency management (Please don't quote me on that ;))
