Add a health check feature

[k33g]

• for capsule http
• and if a function health exists in the wasm module => probably something to add to the MDK

Related issues:

• Add GetHandleHealthCheck method capsule-host-sdk#10
• Add SetHandleHealthCheck and callHandleHealthCheck methods capsule-module-sdk#2

[k33g]

func main() {
	capsule.SetHandleHTTP(func (param capsule.HTTPRequest) (capsule.HTTPResponse, error) {
		
	})

	capsule.SetHandleHealthCheck(func (param capsule.HTTPRequest) (capsule.HTTPResponse, error) {
		
	})
}

👀 https://vertx.io/docs/vertx-health-check/java/

[k33g]

func main() {
	capsule.SetHandleHTTP(func (param capsule.HTTPRequest) (capsule.HTTPResponse, error) {
		
	})

	capsule.SetHandleHealthCheck(func (param capsule.HTTPRequest) (capsule.HTTPResponse, error) {
		
	})
}

other solution: call exported function

//export OnHealthCheck
func OnHealthCheck() uint64 {
	capsule.Print("⛑️ OnHealthCheck")

	response := capsule.HTTPResponse{
		JSONBody: `{"message": "OK"}`,
		Headers: `{"Content-Type": "application/json; charset=utf-8"}`,
		StatusCode: 200,
	}

	return capsule.Success([]byte(capsule.StringifyHTTPResponse(response)))
}
