Keep Your Library Simple: Scala API Design Case Study

Keep Your Library Simple: Scala API Design Case Study

We've been using Play Framework with Elasticsearch and elastic4s for a while. Getting it all to work together requires some boilerplate code, though. We decided to create a small library that would make things easier in future projects. We learned some lessons about building Scala libraries along the way.

Practical Intro to Monads in JavaScript

Practical Intro to Monads in JavaScript

If you’ve heard about Monads but never had time learn them, here’s a simple explanation. Not a theoretical nonsense. It’s a simple, practical tutorial for JavaScript developers showing how some monads can be used. It’s for engineers, not scientists.

Overcoming Pre-Commit Code Review Challenges

Overcoming Pre-Commit Code Review Challenges

Pre-commit code review can provide some tremendous benefits: It improves quality of the final code, it helps team members to learn from each other. It also propagates knowledge about projects and best practices. But it also generates additional problems. Here's how we dealt with them.

Static Typing in JavaScript & Best Tools to Do It

There are three popular possibilities – jsDoc (with e.g. Google Closure Compiler), Facebook Flow and Microsoft TypeScript. First one uses comment like annotations – does not corrupt pure JS – while next two extend JS so they have to be transpiled. I will compare them briefly in a moment.

Before You Build A Web App - Pre-development REST Checklist

The abundance of all the tools and resources makes building web applications seemingly effortless. The framework will handle the routing, the library will process the requests and the template engine will take care of any UI you need. This is all very convenient, but it doesn't deal with the greatest risk of all: having your web service destroyed before you start coding.

Open Source Async MongoDB driver for Scala & Play Framework (early version)

Here at Evojam we're heavy users of Scala, MongoDB, and the Play Framework. So naturally, when MongoDB introduced the 3.0 Java Driver we were quite excited to see that it featured an aysnchronous core. Unfortunately after some research it seemed that the Scala community didn't share our enthusiasm.

API landscape 2015: Swagger, Hypermedia & Microservices

Joint conferences API Days and API Strategy & Practice took place during the last weekend in  Berlin. We’ve had the pleasure of spending great time with the people at the epicenter of the exploding API ecosystem. Read to learn what are the hot topics and possible implications for your apps.

Glimpse at the State of Functional Programming

Recently, our whole backend team visited Lambda Days - The Functional Programming Conference. Two days, multiple presentation tracks, lobby and pub talks gave our five agents unique glimpse into the state of the functional programming ecosystem.
