俺は - an Async friendly Redis binding in pure OCaml.
It is availaible on OPAM, just
opam install orewa
and off you go! No need to install any native libraries or other dependencies.
To connect to a Redis server use
Orewa.connect which will return a handle to
a connection. From here you can use all the implemented Redis commands in
Orewa.* and also close the connection with
Orewa.close. Or just use
Orewa.with_connection to handle connection handling for you.
Orewa opts in to offering an OCaml-centric API, so the commands map to
functions and these take typed arguments. So instead of distinguishing between
seconds and millisecond variants, in Orewa both are represented by a time span
type. Different options to commands are represented by ADTs, to avoid
constructing invalid commands. The results are mapped into the most fitting
OCaml data types. Orewa also avoids exceptions, so the signature will tell you
exactly which error types are expected.
The integration test in
src/integration/test.ml attempts to test all
implemented commands, so it demonstrates how each of them can be used.
Currently all commands from the string category in Redis 5 are implemented.
Over time this set is meant to be expanded. If you need support for a specific
command, submit a pull request.
For a very preliminary draft of what could be coming over time here's a list of

Cluster support, maybe. Unlikely to happen any time soon.
