# wasmCloud TinyGo Actor SDK

This module is for those looking to develop [wasmCloud](https://wasmcloud.dev) actors using [TinyGo](https://tinygo.org). Typically you won't use this module directly, as it will be referenced by one or more code generate modules containing strongly-typed structs and wrappers around function handler registration.

A typical actor might look like this

```go

package main

import (

	"github.com/wasmcloud/actor-tinygo"

	"github.com/wasmcloud/interfaces/httpserver/tinygo"

)

func main() {

	// In the main function, construct an instance of your actor, and pass in the instance,

	// followed by a handler for each of the interfaces you implement.

	// This actor responsds to http requests from the http server capability provider,

	// so it includes the HttpServerHandler.

	// All actors must include the ActorHandler and implement `HealthRequest`.

	me := Echo{}

	actor.RegisterHandlers(httpserver.HttpServerHandler(&me), actor.ActorHandler(&me))

}

type Echo struct{}

// HandleRequest implements the callback from the http server capability provider.

func (e *Echo) HandleRequest(ctx *actor.Context, arg httpserver.HttpRequest) (*httpserver.HttpResponse, error) {

	r := httpserver.HttpResponse{

		StatusCode: 200,

		Header:     make(httpserver.HeaderMap, 0),

		Body:       []byte("hello"),

	}

	return &r, nil

}

// HealthRequest implements the health check from the wasmcloud host.

func (e *Echo) HealthRequest(ctx *actor.Context, arg actor.HealthCheckRequest) (*actor.HealthCheckResponse, error) {

	var r actor.HealthCheckResponse

	r.Healthy = true

	return &r, nil

}

```
