hi again, I am learning GraphQL with Elixir this days, it is looking so funny. I have a question about chat app with this api. For chat app we will need rest api for instance ?

If you’re using GraphQL, then you should probably look for Absinthe and read how to implement real-time using subscriptions.
In my opinion, I prefer to use REST api for a chat app since its easier to build and get started.
Skysoft13
yes definitely I am use absinthe
, but I have qurious about how u implement the api with chat api . If you have server , why you will need api?
kokolegorille
You could use websocket instead…
It is very powerful

I misunderstood, if you’re gonna build a chat app and you’re using phoenix, then you can leverage phoenix channels.
Skysoft13
no I mean for example if you want to use develop mobile chat app like viber or telegram, u will need chat server like ejabberd, mongooseIM …etc, but I have curious about why you will use Rest Api? those companies use api for communication between mobile client and chat server?

Because it is more reactive than REST, or GraphQL api.
Phoenix channels are something You should try, if You don’t know what it is…
