Providers are swappable wasmCloud host plugins. They are executables (usually dedicated to longer-lived processes) that deliver common functionalities called capabilities. Providers are typically responsible for capabilities that are not considered part of the core business logic of an application, such as...
- Sending notifications
- Fetching secret values
- Accessing databases
- Serving content over HTTP
This package is an SDK for creating capability providers in Golang. You can implement a capability that's already defined, or create a custom capability interface and use that in your wasmCloud application.
An example can be found in examples/keyvalue-inmemory which implements the interface wrpc:keyvalue/store@0.2.0-draft.
Refer to the custom template for a comprehensive example of a custom provider.
