Example actors, capability providers, and other demonstrations

Actors

The following actors run as WebAssembly on wasmCloud hosts.

Example	Description	OCI Reference (refer to example for latest version)
echo	An actor that listens on an HTTP port and returns a JSON payload describing the incoming request	`wasmcloud.azurecr.io/echo`
echo-messaging	An actor that listens on a message broker topic and replies	`wasmcloud.azurecr.io/echo-messaging`
hello	Canonical "hello world" actor that listens on an HTTP port and replies with a greeting	`wasmcloud.azurecr.io/hello`
kvcounter	An actor that uses the key-value store to increment a counter and return a value for every HTTP request it receives	`wasmcloud.azurecr.io/kvcounter`
logging	An actor that demonstrates the builtin logging capability provider	`wasmcloud.azurecr.io/logging`
random	An actor that demonstrates the builtin random number generation capability provider	`wasmcloud.azurecr.io/random`
todo-sql	An todo-application using sql database, https server (with TLS), logging, and numbergen	(unpublished)
todo	An todo-application using keyvalue store, http server, and logging	(unpublished)
xkcd	A application that generates xkcd comics	`wasmcloud.azurecr/xkcd`

The following example interfaces are defined by Smithy models.

Example	Description	Capability contract	Rust crate
payments	A simple interface for a payments capability provider (used in the Creating an Interface tutorial)	`wasmcloud:example:payments`	`wasmcloud-examples-payments`
runner	A simple interface with a single 'Run' method	`wasmcloud:example:runner`	`wasmcloud-examples-runner`

Providers of capabilities for wasmCloud actors

Example	Description	Capability contract	OCI Reference
factorial	A capability provider that computes factorial of a number	`wasmcloud:example:payments`	`wasmcloud.azurecr.io/factorial`
fakepay	A simple payment provider, used in the Creating a capability provider tutorial	`wasmcloud:example:fakepay`	`wasmcloud.azurecr.io/fakepay`

Example	Description
petclinic	A WebAssembly and wasmCloud-based reimagining of the classic Spring Boot microservices Pet Clinic. The wasmCloud Pet Clinic consists of multiple actors, and uses a relational database capability provider and an http server capability provider.

Examples compatible with the 0.18 wasmcloud host have been moved to the pre-otp folder.
