Guys if you're watching this video at the moment, just note that dictionary API has changed. It doesn't contain "origin" field nowadays. So remove it in the app files to make the app work.

Ehhh. That getWordInfo function implementation looks a bit strange. Couple of things I am curious about there. When you catch and emit an error the code block seems will continue to emit the success case afterwards. Secondly. Do you really want to group the api get request and the saving/deleting to database together in the try catch block? Now it could be the case that the api call went well, but you will be emitting old data when you run into a database exception?

Great video but, there's a little issue with Converters class. Unfortunately the *object : TypeToken(){}.type* call depends on GSON library. This invalidates the huge interface usage advantage. In fact if you implement a JacksonParser you are forced to use *object : TypeReference(){}.type* . Do you have any idea to solve this problem?

Thanks a lot for your lessons. They are really helpful. The only question I have, is repository a good place to make network request? For me it looks like use case should do it. But in this way repository will have all create/delete/get methods, that duplicates DAOs methods... What do you think about it?

@PhilippLackner 2 жыл бұрын

No, thats what the repo does. It accesses your different data sources and provides functions for the use cases. The use cases shouldn't know where the data comes from. They're part of the domain layer, not data

No it's the other way around. Domain is the innermost layer. All layers can access domain, but not all layers can access data

First of all Thanks for this tutorial, great as always, my question is, In line 26 in WordInfoRepositoryImpl, we want to delete old cached data, right? but you pass to the delete function remoteWordInfos (the new data) instead of wordInfos (the old data). Is what I am saying right?

I would assume you have already some SOLID principles, some design patterns and Architecture knowledge, I also ask the same thing (not exactly what you asked but the thought of it), most of the time if not always, ask yourself first if you need to do it, "YAGNI". Imagine youre doing a simple Dashboard proof of concept (POC) for lets say a user profile information to show some stakeholder a glimpse of your team's feature, I wouldn't mind architecting them at all, I'm just gonna throw everything in 1 package, but still follow the principles that I know as much as possible. trust me YAGNI principle saves me a lot of headache

coroutines dependency for Flow, we can't use flow without it. Lifecycle scope wasn't needed here because he was already using live data otherwise it is required for repeatOnLifecycle or launchIn blocks that are much needed when using flow inside the ui layer as well.

@pierre.vieira 2 жыл бұрын

I found it a little strange that you put the data retrieval logic in `WordInfoRepositoryImpl`, in this case the ideal would not be to do this in the use case `GetWordInfo` making `WordInfoRepositoryImpl` only make the calls of the methods present in the `api` and in the `dao`?

@PhilippLackner 2 жыл бұрын

But in the end that's exactly the job of the repository to decide which data goes through. Not sure if the use case really needs to know about what happens with the data, it should actually just get it and not care where it comes from

@pierre.vieira 2 жыл бұрын

@@PhilippLackner I understood what you said. However, it still seems a little strange because in this case `WordInfoRepositoryImpl` executes some data type conversion logic and is responsible for controlling the states of "loading", "error" and "success", for me this shouldn't be role of the repository, but just worrying about informing how the data will be obtained. For me, in this case, the best way would be for the repository to have 2 methods something like: `getDataFromWeb` and `getDataFromDatabase`, in the repository implementation we would only call the methods present in `api` and `dao` respectively, without worrying about "emit" logic (loading, error and success) and how the caching should be done, passing that responsibility to the use case... But of course that's just the way I see it and I'm not specialist.
