The wasmCloud Pet Clinic example application is a WebAssembly and wasmCloud-based reimagining of the classic Spring Boot microservices Pet Clinic example.

The wasmCloud Pet Clinic consists of the following five actors:

• Clinic API - The main JSON (aka "REST") API gateway for interacting with the service
• Customers - Customers/Owners Actor - roughly equivalent to the original Customers/Owners microservice.
• Vets - Veterinarians actor, roughly equivalent to the original Vets service.
• Visits - Visits service, roughly equivalent to the original visits service.
• UI - An actor that contains all assets for the petclinic UI. This actor will serve the assets through the Clinic API

The wasmCloud Pet Clinic application has a simple architecture: simply start all five of the actors, push a link definition between the Clinic API actor and an HTTP Server capability provider, and then push link definitions between the Customers, Vets, and Visits actors and a relational database. Lastly, ensure that both the HTTP Server and relational database capability providers are started.

If you'd like a quick out of the box example of the petclinic, you can use the included run.sh script to automatically spin up a running wasmcloud host, database, and all the actors. This does require docker to be installed as all the dependencies are run as docker images. To start everything, run:

$ ./run.sh all

To cleanup everything when you are done:

$ ./run.sh wipe

Once it is running, you should be able to access the PetClinic application on localhost:8080
