Phoenix 1.3 is pure love for API development | Oscar Swanros
Phoenix 1.3-rc.0 was just released, and while it’s still not a final release, it already feels solid as h*ck. I’ve been doing a personal project on the side for a while now, and it has a web API component, which I wrote in Phoenix 1.2. That was my first time using Phoenix on a serious project that I intend to ship. With the release of Phoenix 1.3, and after I watched Chris McCord’s talk about the
How to use raw sql with ecto Repo
I have an upsert requirement, so I need to call a postgres stored procedure or use a common table expression. I also use the pgcrypto exgtension for passwords and would like to use postgres functions (such as "crypt" to encode/decode passwords). But I can not find a way to get Ecto to play with raw sql in part or whole, is it intended that ecto will only support the elixir dsl and not allow shelli
Subdomains With Phoenix - Gazler
A common requirement for applications is to have a subdomain per customer that users belonging to that customer can visit. Example of this include: Slack (https://elixir.slack.com, https://phoenix.slack.com, etc.) and ReadMe. This blog post will go through how to set up your Phoenix application so that it can be used in the same way. The source code for this repository is available at https://gith
Phoenix で Redis の Pub/Sub を使って WebSocket をスケールアウトさせる - Qiita
WebSocket を利用するアプリケーションは Pub/Sub サーバを使ってスケールアウトさせるのが一般的です。 今回は Redis の Pub/Sub 機能を使って Phoenix の WebSocket をスケールアウトさせてみます。 Phoenix で WebSocket 通信をさせる方法はコチラをご参照ください。 事前知識: WebSocket アプリケーションのスケールアウトについて 通常の Web アプリケーションにおけるスケールアウトは、サーバ台数を増やしてロードバランサでリクエストを分散させる、というのが一般的ですが、WebSocket アプリケーションではこの手法が使えません。 なぜかというと、WebSocket アプリケーションはコネクションをサーバ内で管理するステートフルな作りになっているためです。冗長化させたサーバにリクエストを分散させてしまうと、他サーバで接続
How to detect if a user left a Phoenix channel due to a network disconnect?
I have an Elixir/Phoenix server app and the clients connect through the build in channels system via websockets. Now I want to detect when an user leaves a channel. Sidenote: I'm using the javascript client library inside a Google Chrome Extension. For this I extracted the ES6 code from Phoenix, transpiled it to javascript, and tweaked it a little so it runs standalone. Now when I just close the p
Convenience hacks for using exrm with Phoenix apps

Assumes a freshly generated Phoenix app called hello_phoenix & the current working dir is the project’s root dir. The setup Add exrm as dependency in mix.exs Fetch & compile deps Generating & running apps via releases As soon as you generate a Phoenix or any mix app, your app’s version in mix.exs wo
Using page-specific page titles in the Phoenix framework
Written using Phoenix 0.13.1 One common task in web apps is setting a custom page title for each URL - your homepage should have a different title than a page listing out all of your projects (for example), which should have a different title than a page showing details of a single project. There isn't a built-in way to do this in Phoenix, but after much reading around forums, GitHub issues, etc.
Practical i18n with Phoenix and Elixir
With the recent addition of Gettext to the Phoenix framework, there is now a production worthy way to ensure one's application can reach the broadest possible market. Internationalization is an important part of application design, yet implementing i18n in a practical manner can be daunting, especially in a new technology. While there are examples showing the basics of utilizing gettext in a Phoen
Working with Ecto associations and embeds « Plataformatec Blog
This blog post aims to document how to work with associations in Ecto, covering how to read, insert, update and delete associations and embeds. At the end, we give a more complex example that uses Ecto associations to build nested forms in Phoenix. This article expects basic knowledge Ecto, particularly how repositories, schema and the query syntax work. You can learn more about those in Ecto docs
Phoenix上でgen_emqttを用いたMQTTのsubscriberを作る - Qiita
#はじめに IoTという言葉が流行し始めて以後、M2M用プロトコルとして、世間のMQTTに対する意識は急上昇の最中にあります。自然と日の目を見るのはMQTTブローカーの存在でしょう。枯れたところではJMS実装のActiveMQから、最近ではerlang実装のemqttやvernemqなど、実に様々なブローカーが世間を賑わせております。 しかしながら、いざ実際にサービスとしてIoTなアプリケーションの開発を考えたとき、ネックとなるのはMQTTブローカーとは別のところにあります。ブローカーは基本的にパッケージとなっていて、簡単にインストールできます。管理UIが付属する製品も少なくありません。SaaSサービスを利用するという手もあります。 Publish（端末）側もデータを投げるだけなので、こちらも実装は比較的簡単です。 問題なのは端末を集約するSubscriber（データベース）側です。gem
