Serving encoded JSON with POISON
When building JSON APIs you often find yourself in a situation when you have part of the JSON already encoded and want to embed it in a bigger structure. A common solution is to decode the encoded part and embed the outer structure just to encode it back again. It’s obvious how that back-and-forth decoding and encoding is wasteful. Fortunately with poison we have a much better alternative.

Flowex - Railway Flow-Based Programming with Elixir GenStage
Flowex is a set of abstractions build on top Elixir GenStage which allows writing program with Flow-Based Programming paradigm. I would say it is a mix of FBP and so-called Railway Oriented Programming (ROP) approach. Flowex DSL allows you to easily create “pipelines” of Elixir GenStages.

HTML parsing in Elixir with leex and yecc
As part of my attempt to build a text-based web browser, I needed an HTML parser I could use from Elixir.
Rather than jump straight into an existing solution, I decided to see how writing a parser with leex and yecc would go (ultimately deciding a library was a better option).
Using Elixir's GenStage and Flow to build product recommendations
A real-world example of building a computational parallel pipeline using Flow.
Crowdsourcing product mentions, applying sentiment analysis, and scoring to rank products. Used to build the Start learning Elixir recommendation website.
Step-by-step guide to building, visualising and optimising a pipeline built with the new Flow library.

A project I started a few months back to learn Elixir.
Simplifying Elixir Releases with Edeliver
Check out this article about using edeliver to simplify your Distillery-powered Elixir releases.
OK 1.3.0: Added `with` special form for `:ok/:error` tuples
Improved sugar for combining multiple functions that may fail. Very useful in clearing up code with a high branching factor due to error cases. Works by considering tagged tuples as a result monad and providing the relative for comprehension.
