Hi there!

I just published v0.1.0 of neuron, a tiny GraphQL client for Elixir.

Contributions are always welcome, I’ll keep adding features in the future :)

I am happy to announce that I am completing final rounds of my Phoenix book and am opening up pre-order for my book with 15% off.

You can read more about the book at https://shankardevy.com/phoenix-book/

Topics covered in the book are:

• Learn just enough Elixir to dive into Phoenix
• Create a mini-Phoenix framework using Elixir and Cowboy
• Plug magic in Phoenix Endpoint, Router and Controller
• Develop an ecommerce site in Phoenix using Test Driven Development
• Practical Ecto Cookbook
• Blueprints to help you better design your project
• Access to lots of handy reference cheatsheets!
• Full access to all code repos used in this book.

Phoenix Inside Out is approx 350 pages and is organised in three parts as follows:

• Part I. (Introduce) Readers might come to Phoenix without knowing Elixir. So teach them just enough basic to understand Phoenix code. Knowing the language fully well is indeed necessary for mastery but it’s very easy to get lost in learning Elixir.

• Part II. (Demystify) The book explains the internals of Phoenix by showing user how to create something like Phoenix. I believe the best way to learn how a framework works is to create it yourselves. And the best way to use it in your project is to learn how it works.

• Part III. (Empower) The book demonstrates building an commerce site using TDD. Hound is used for acceptance testing. This part also introduces Ecto and Contexts as in Phoenix 1.3. I also explain various deployment options that you can put to use in your project.

Practical Ecto cookbook is approx 120 pages with about 60+ recipes under the following headings

• Schema
• Embedded Schema
• Migration
• Changeset
• Association
• Query

I wrote a short post to (hopefully) make it a little easier to understand how to use Elixir’s Enum.filter_map/3 to filter and map a collection.

Need to test that tricky function? Here’s a story of a refactoring that allowed us to add some good new tests for a new feature in Benchee.

Transitioning monolithic apps into a micro-service architecture isn’t straightforward – in fact, it is often quite difficult. In this intermediate talk, we’ll learn how Elixir umbrella apps and Phoenix utilize the Erlang VM (BEAM) to make building services less painful and more productive.

How to build a template engine (using simple string interpolation), leveraging pattern matching and state machines while measuring overall performance.

In our latest embedded-elixir blog post, Connor Rigby describes how to manage multiple versions of Elixir and Erlang/OTP using ASDF-vm. http://embedded-elixir.com/post/2017-05-23-using-asdf-vm/

I’m starting a series of posts to people from Java learn Elixir faster. I hope you guys like it.

Changes include:

• Flag for an additional SQL injection vector
• Small addition to XSS checks
• Minor bug fixes and refactoring

Changelog

Enhancements

• Extract Retort.Resources.timeout/2 to Retort.Resources.Timeout.get_or_default(module, function). Retort.Resources.Timeout also has functions for deleting and putting module-wide and function name specific timeouts, to make testing easier and less boiler plate needed in override examples.
  • Retort.Resources.Timeout.delete(module) will delete timeouts set by Retort.Resources.Timeout.put(module, timeout) OR Retort.Resources.Timeout.put(module, function_name, timeout).
  • Retort.Resources.Timeout.delete(module, timeout) will delete timeout set by Retort.Resources.Timeout.put(module, function_name, timeout) OR remove the timeout for function_name and leave it for the other function names when Retort.Resources.Timeout.put(module, timeout) is called.
  • Retort.Resources.Timeout.put(module, timeout) will set the timeout for all Retort.Client.Generic calls by module that called use Retort.Resources.
  • Retort.Resources.Timeout.put(module, function_name, timeout) will set the timeout for all Retort.Client.Generic function_name calls by module that called use Retort.Resources.
  • Retort.Resources.Timeout.put(module, function_name, timeout, func) will only temporarily Retort.Resources.Timeout.put/3, but for the duration passed function only. This can be used to test timeout handling.
• Update to credo 0.7.4.

Bug Fixes

• Fix formatting of timeout override example code.

Deprecations

• Retort.Resources.timeout(module, function_name) is deprecated; use Retort.Resources.Timeout.get_or_default(module, function_name) instead.

Hi there,

I just published my first Phoenix project Startup Job, an umbrella project to search startup jobs which scraped from various websites.

You can find out more on the GitHub repo.
