The State of Elixir HTTP Clients

In today’s post, we’ll look at two Elixir HTTP client libraries: Mint and Finch. Finch is built on top of Mint. We’ll see the benefits offered by this abstraction layer.

Finally, we’ll put together a quick project that makes use of Finch to put all of our learning into action. Let’s jump right in!

Node.js Resiliency Concepts: The Circuit Breaker

In 2009 Node.js opened up a door for front-end developers to dip their toes into the world of servers without having to leave the comfort of their language. It’s almost effortless to get started with Node. You can basically copy-paste an entire HTTP server into existence and then install an ODM and you’ve got your CRUD app ready to roll!
