So today just out of curiosity, I decided to take a step into this world of, ‘InstantMesagging (IM)’ and understand how this technology works to provide us with such an excellent way of communication. Even the notifications we receive on our android cells (GCM), make use of the same underlying technology. Many of us even use these IM clients within our organisations for our official purposes. 'ecto.We all use Gmail (Gtalk, now hangouts), FaceBook, SKYPE, Yahoo messenger, WatsApp and various other messaging tools on a daily basis. # See the documentation for `Mix` for more info on aliases. # For example, to install project dependencies and perform other setup tasks, run: # Aliases are shortcuts or tasks specific to the current project. # Type `mix help deps` for examples and options. # Specifies which paths to compile per environment.ĭefp elixirc_paths(:test), do: # Type `mix help compile.app` for more information.Įxtra_applications: This is my mix.exs defmodule ChatTest.MixProject doĬompilers: ++ Mix.compilers(), I have tried to downgrade ejabberd but it does not seem to be working. So it would certainly not be a bad idea to take a look at the following book if you haven’t already:

A JID has the following form: Make Ejabberd aware of the domain and set a random constant resource.Īt the end of the day, Ejabberd implements the XMPP protocol. Then, with a minimal amount of logic, you can make your client just construct the JID for authentication with Ejabberd und Ejabberd check the credentials. All you need to do is to store it in a way Ejabberd can access it. But you don’t even need to as you can reuse your existing auth. Q2: A JID needs to be generated only once per user. But it is difficult to say and depends on a lot of factors. If you want to store them on the server potentially indefinitely and make the client query them each time (like FB) then I would say Postgres is a better choice. Q1: If you store the messages only until they are delivered and then delete them - giving the client the responsibility to store them (like WA does it) then I would say mnesia is good choice. Q2) Do we generate JID again and again when user connects to the internet or it is generated only once when user first registers? Q1) Should i use MNESIA or Postgresql as Database? (For my reddit part i am using PostgreSQL) Now few additional questions that i have if anyone can answer them I already have implemented basic Auth system with email and password but for chat functionality i think i need to generate somekind of JID as well i guess?Įven after i generate JID lets say how do i implement these one-to-one and multi user chat in my application because Ejabberd docs are some what confusing to me. Researched a little bit more then i came to know about JID (Jabber ID) and then i realized (i might be wrong here) that Ejabberd basically calls functions likeĮjabberdctl send_message chat 192.168.33.50 “subject” “message from server”Īnd i guess here “ is acting like the JID.

I have seen little bit of documentation and few implementation of Ejabberd in elixir but still not able to understand how am i going to implement one-to-one chat and multi user chat and also Video/Voice calls. Thats why i researched more and decided to go with Ejabberd. Like media transfers and how am i going to store messages for offline users and then deliver it.

Initially i thought i could just work with Websockets but they don’t provide all the services i needed. I am almost done with the reddit part and decided to look into how am i going to implement the WA one. My application is what you could say is like Reddit + WA. Alright let’s start with the simple stuff
