👋🏼👋🏼, I'm trying to migrate from apollo 2 to apollo 3 but i can't find how to update this part:

Basically when the app runs a request we use enqueue in order to add a Callback that manage either Success/Failure response, but after migration I see that there's no enqueue option anymore, in the 🧵 there'a a sample code of what we are using.

// Service
fun getMyData(): ApolloQueryCall<GetMyDataQuery.Data> = apolloClient.query(GetMyDataQuery())

// Repository Implementation
override suspend fun getMyData(): Result<Data> = suspendCoroutine { cont ->
        val call = myService.getMyData()

        call.enqueue(object : ApolloCall.Callback<GetMyDataQuery.Data>() {
            override fun onResponse(response: Response<GetMyDataQuery.Data>) {
                 // handle OK response here
            }

            override fun onFailure(e: ApolloException) {
                  // handle Failed response here
            }
        })
    }

My doubt is: what can I use in apollo 3 to add/maintain this callback?

[mbonnin]

It's all coroutines now so you should either call the suspend execute() or use an rxJava bridge if you're using Java

[mbonnin]

Looking at your sample, you're using coroutines already so you should be able to do something like this:

override suspend fun getMyData(): Result<Data> {
  try {
    val response = myService.getMyData().execute()
    // handle OK response here
  } catch (e: ApolloException) {
    // handle error here
  }
}

[Alejandro Rios]

So it's not possible to add a callback handler like in my example code, right?

[mbonnin]

Not really.

[mbonnin]

I guess you could wrap the suspend function if you really wanted to but that'd accomplish nothing besides adding more wrappers

[mbonnin]

Do you specifically need the callback?

[Alejandro Rios]

Mainly because we have a lot of these in our project so I wanted a less invasive solution 😅

From what I see is that the callback is need it because I'm wrapping the call in suspendCoroutine

[mbonnin]

That's the nice thing, you can remove the suspendCoroutine altogether now 🙂

[mbonnin]

Because ApolloCall.execute() is suspend itself so it'll execute in the background and resume when the response is received

[Alejandro Rios]

You're right, thanks for the clarification 👍🏼
