This actor makes use of a single capability, wasmcloud:httpserver, in order to receive HTTP requests and respond with the classic "Hello, World!".

To respond to http requests, the actor must implement the HttpResponse method of the HttpServer interface interface.

The implementation is in the file src/lib.rs

• To compile the actor and generate a signed Webassembly module, type wash build.
• Run the wasmCloud host with wash up
• In your browser at localhost:4000, in the Actors table, use the dropdown to start the actor From File and select the built and signed module from step 1
• Start the HTTP server provider From Registry with OCI reference wasmcloud.azurecr.io/httpserver:0.17.0
• Link your hello actor to the HTTP server provider with a link value of address=0.0.0.0:8080
• curl localhost:8080 to see your response, or follow the browser instructions below

Visit the url "http://localhost:8000" to see your response in the browser.

• You can change what contracts this actor claims in wasmcloud.toml and the Makefile. In the future this will just be in wasmcloud.toml.
• You will then need to change the dependencies in Cargo.toml to import the interfaces for the contracts you want. Delete the wasmcloud-interface-httpserver dep if you're not using that contract.
• Finally, change the src/lib.rs file, changing/deleting the current interface import and impl block, while adding a new import & impl for any contracts you added!

The generated project include two GitHub actions: build.yml and release.yml under .github/workflows. The build action will automatically build, lint, and check formatting for your actor. The release action will automatically release a new version of your actor whenever code is pushed to main, or when you push a tag with the form vX.Y.Z.

These actions require 3 secrets

1. WASH_ISSUER_KEY, which can be generated with wash keys gen issuer, then look for the 58 character Seed value
2. WASH_SUBJECT_KEY, which can be generated with wash keys gen module, then look for the 58 character Seed value
3. WASMCLOUD_PAT, which can be created by following the Github PAT instructions and ensuring the write:packages permission is enabled
