How we can use the gen_statem behaviour to implement a resilient state machine that holds a connection to an external service.

Elixir makes it easy to build fast and scalable network applications. Here is a basic HTTP proxy server in less than 20 lines of Elixir code.

It’s time for another Elixir Alchemy! We'll learn by building today. We're building an HTTP server with a Plug adapter, which parses requests and builds responses so it can run Plug apps.

Discover how Phoenix Components serve as reusable building blocks in modern web applications

I thought it would be nice to make a streaming music service focused on bringing lo-fi artists and listeners together. Early on, I put together a series of prototypes to explore with a small group of listeners and artists. Since this is a technical article, I'll jump right into the requirements we arrived at, though I'd love to also do an article on the strategies and principles that guided our exploration.

How to abuse Ecto embeds to do our dirty polymorphic bidding.

Developer Paul Scanlon shows how to recreate Shopify's 3D Thanksgiving globe, using a React component for globe data visualization.

In this article, we outline some of the technical details of GenServers in Elixir, which is used to serve a large multitude of people with high speed. This is a deep dive into GenServers and discovering their limitations and strengths.

Phoenix LiveView has implemented some fantastic features, and one of them is the on_mount/1 callback...

In the second part of our series, we'll build on our multi-tenant Phoenix application using Ecto custom types and other methods.

Hello Elixir enthusiasts! 🚀 As the tech landscape evolves, so should our tools and approaches to development. Today, I'm excited to introduce you to a significant advancement in Elixir development that can reshape how we build distributed systems – I present to you Spawn.

Have you ever needed to build solutions related to execution flows like wizards, admission processes, or game rules in your software? If you do, you know it can be a nightmare of conditionals and complexity. We can make our lives easier by developing them using state machines.

Learn when you should use state machines and how to build one with Elixir's Ecto.

Read about elixir streams and lists comprehensions. Whenever you deal with lists, maps, keyword lists, and such.

The Req Elixir library doesn't support file uploads(as of version 0.4.5). Instead, you need to use multipart to construct the HTTP request before you send it.

C++ is definitely a language that has Lots of Ways to do It – kind of like Perl’s TIMTOWTSAC. A consequence is that when writing code, you need to think about which way to do things. When context-switching between projects, employers, or what-have-you, you may have to context-switch preferences for which way is preferred. Guidelines can help, and I love them.

In the first of a two-part series, we'll set up a multi-tenant Phoenix application.

Floki makes it easy to parse and query HTML documents in Elixir using CSS selectors and tree traversal.

A lot has been said about The Actor Model when it comes to Erlang. The Actor Model is generally a model for concurrent computation. And Erlang was not built to implement Actors. I'm sure we could be debate about whether it does or not. I have not read Carl Hewitt and I'm not going to offer an opinion. It does something similar enough in terms of message passing and spawning. It might be the case that Erlang processes has shifted what people expect an Actor to be and rather than be a realization of the theory it has become an implementation that overrides the theory.

Unveil the power of the generate_series function in PostgreSQL for automated data generation. From simple number sequences to complex time-series data, learn how to streamline your SQL operations with practical examples and use cases.

Explore how Phoenix handles uniqueness validation with Ecto, and why it's a more elegant solution compared to Rails.
