http4s-laminar-stack

Example of

1. Client written with Laminar, interacting with server using sttp

2. Server with http4s serving both the compiled Javascript for the client and an endpoint for server-side interactions

3. Shared code with protocol definitions

4. Gzip compression on the server side

5. Docker packaging of the full application

6. Tests for the client with simulated DOM using jsdom

Development mode

Run in SBT (uses fast JS compilation, not optimized):

sbt> ~runDev

And open http://localhost:9000/frontend

This will restart the server on any changes: shared code, client/server, assets.

Production mode

Run in SBT (uses full JS optimization):

sbt> ~runProd

Docker packaging

sbt> backend/docker:publishLocal

Will publish the docker image with fully optimised JS code, and you can run the container:

✗ docker run --rm -p 8080:8080 backend:0.1.0-SNAPSHOT
