This example exposes the actions using http, and also events using websockets..
the client side is here: https://github.com/moleculer-go/example-whatsapp/blob/master/pages/contacts.js
on line 29
contacts = await postRequest("/api/contacts/find", {
query: { deviceToken }
});
query: { deviceToken }
});
this calls the service contact action find --> https://github.com/moleculer-go/example-whatsapp/blob/master/services/contacts.service.go
back to the UI code.. on line 252:
const result = await postRequest("/api/chat/sendMessage", {
contactId: contact.id,
deviceToken,
message,
target,
individual
});
contactId: contact.id,
deviceToken,
message,
target,
individual
});
calls this action here: https://github.com/moleculer-go/example-whatsapp/blob/master/services/chat.service.go#L55
see that this action.. returns a simple map
return map[string]interface{}{
"result": "message sent",
}
"result": "message sent",
}
which to the web front end .. the response will be an application/json -> {result:"message sent"}
so.... const result = {result:"message sent"}

// ⭐ You can also have an action that receive no parameters ⭐

Here's my test code
Here;'s the postman test
and I was successfully get the json data but it's not application/json
It's a text/plain
