25 July 2017   964

Good news for all Elixir coders and especially for Phoenix fans. New, 3rd and last release candidate of version 1.3.0 is finally out.

According to the developers, the final release of version 1.3.0 is planned later this week. 

Let's check what's inside!

Directory Changes

The "web" directory has been moved from lib/my_app/web, to lib/my_app_web. This change makes a clearer separation between your greater Elixir application and the web interface to it. The new convention also aligns more closely to the umbrella application structure, so it will be a more natural step to go from a single application to an umbrella application in the future. For example, the new structure produced by mix looks as follows:

├── my_app
│   ├── application.ex
│   └── repo.ex
├── my_app.ex
└── my_app_web
|   ├── channels
|   ├── controllers
|   ├── endpoint.ex
|   ├── gettext.ex
|   ├── router.ex
|   ├── templates
|   ├── views
└── my_app_web.ex

Web alias changes

The MyApp.Web alias has been renamed to MyAppWeb. This removes a special-case naming convention we had that went against common Elixir conventions when it comes to naming umbrella applications.

New Channel V2 wire protocol

rc.3 also includes a backwards-compatible, V2 of our channel wire protocol. The new protocol resolves a race condition that was discovered under some messaging circumstances. The new format also includes improved data compaction when serializing. The updated phoenix.js client will use V2, but older clients unable to speak the new protocol will continue to work as before.

Dynamic Endpoint config changes

The rc.0-2 on_init configuration is no longer supported. Instead of on_init, add the load_from_system_env: true to your endpoint config, then define an init/2 clause in your endpoint module. For example:

config :my_app, MyAppWeb.Endpoint,
  load_from_system_env: true,

and then in your endpoint:

@doc """
  Callback invoked for dynamically configuring the endpoint.

  It receives the endpoint configuration and checks if
  configuration should be loaded from the system environment.
  def init(_key, config) do
    if config[:load_from_system_env] do
      port = System.get_env("PORT") || raise "expected the PORT environment variable to be set"
      {:ok, Keyword.put(config, :http, [:inet6, port: port])}
      {:ok, config}

Context Generator changes

The mix phx.gen.html|json|context generators no longer namespace tables by the context name, preferring to simply name the table after the given resource.

22 January 2018   256

Club ElixirLangMoscow invites all lovers of Elixir, Erlang and functional programming languages to the next meeting of our club. This time the event was decided to be held in the "Dear, I will call back" bar. Because, what could be better than listening to interesting reports for a glass of beer. And even in the company of friends!


We are waiting for two cool reports and a free microphone for those who have something to say.

The report will highlight the Agala framework - a platform for real-time interaction with third-party services. Currently, this platform has implemented bots for Telegram and Vk, which are used in the combat environment in our company. Let's analyze the main differences from the known solutions for creating bots on Elixir, consider the internal structure of the platform and learn how to support any necessary third-party service.

This will be an introductory report with Apache CouchDB and its ecosystem. Main features and capabilities. Details of the implementation of the replication protocol and why this is important. Forks: Couchbase, Cloudant - what are the differences and why should not they be confused with the original project. The history of clustering, what happened in the end in 2.0 and how it works. What is interesting about the new release and where the project is heading.

As a pleasant chip, the bar will prepare an "Elixir" cocktail especially for us. Admission is free, everyone pays their bill.

The event has an age limit of 18+. Register for free.
