In this episode we’ll update an existing JSON API to follow the JSON:API specification. To help us, we’ll use the the JaSerializer package.

#82: JSON API with Phoenix 1.4

This episode is a great introduction for anyone wanting to build a JSON API with Phoenix. We’ll build a simple read-only API for an existing Elixir application.

In this episode we’ll use proactive caching with Cachex. Proactive caching can help ensure there is never a cache miss since data is loaded when the application starts.

Alchemist's Edition

#79: Caching with Cachex

Here we look at how to use Cachex to create a cache in an Elixir application. We’ll start by seeing how to interact with Cachex and then we’ll implement a simple cache in our application.

#78: Phoenix Contexts

Phoenix contexts are modules that group associated functionality. To see how they work, we’ll build a simple blog with comments. This is a great episode for anyone new to Phoenix or wanting to see how contexts work.

#77: Validating API Parameters Part 2

In this episode we’ll explore another way to validate API params. We’ll update our existing example to use the Params package, which reduces much of the boilerplate of defining Ecto schemas and changesets.

Alchemist's Edition

#76: Validating API Parameters Part 1

In this episode we’ll see how we can validate API parameters . We’ll take a simple search API and use schemaless Ecto changesets to validate the request parameters.
