Programming

Today we are going explore how to write API clients in the Elixir language. This is a follow-up article to my presentation at OpenCamps…

When writing Unit Tests or Integration Tests for an API that exposes events, we need a way to validate that the events are called. The simplest approach would be to set a variable when the event is called. In the test itself we can sleep for a certain duration and check the variable:

Phoenix serves static files with a Plug.Static defined in the endpoint. But what if we want to serve additional static files from subpaths?

TIL is an open-source project by Hashrocket that exists to catalogue the sharing & accumulation of knowledge as it happens day-to-day.

A brief guide to build an extensible API client

Formating automatically each time a file is saved improves legibility and consistency, making it easier to spot mistakes.

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.

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.

Recently, I have been looking for ways to optimize my Stream Closed Captioner application. During one of my typical scroll-throughs of my Following lists and other sites, I discovered Nebulex. Nebulex, a local and distributed caching toolkit for Eli...

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.
