We have been busily re-building our core property listings experience using ReactJS for a while now. After the release of our revamped sold property section, we decided to find a way to engage the other areas of the company and give back to the local tech community.
With that in mind, REA Group is very excited to announce that on the 8th – 10th February 2017 we will be hosting a ReactJS workshop run by the amazing React Training team. React Training is a US based group comprised of ReactJS experts and the creators of some of the most popular open source libraries in the space, many of which we use here.
In this blog post, I'm going to demonstrate how Reactive Streams can allow us to elegantly work with DynamoDB, a key-value data store with a predetermined write capacity.
DynamoDB is an Amazon managed NoSQL database.
Amazon DynamoDB Documentation
The performance characteristics and client behaviour of DynamoDB are very different to traditional data stores (for example, databases). When working with a relational database, performance may gradually decrease as load on the database increases. DynamoDB tables have a configurable read and write capacity, specified as the number of reads / writes per second the table will accept. AWS charges based on the provisioned capacity. Exceed this limit and DynamoDB will reject the read / write. If using the AWS Java client, this failure will be represented as a
In this blog post, I'm going to provide a very simple explanation for Applicatives (aka "Applicative Functors") just the way I know them. I'm not going to cover the math behind it, or the laws which applicatives must obey.
I've taken a reverse approach compared to many other posts explaining Applicatives: rather than starting with what Applicatives are, I'm going to start with some examples to demonstrate the need for them, then I'll show how Applicatives can be used and at the end, I'll briefly cover how they can be implemented.

I have recently been on a Higher Order Component (HOC) craze. HOCs are a good tool for implementing cross-cutting concerns or common functionalities, such as logging and tracking. For more information on HOCs, check out this recent post by my colleague Mehdi Mollaverdi!
Then I discovered Functions as Child Components (FaCC) and a couple of my brain cells perished. FaCC’s are components that receive a function as their child. For example:
So let’s take a trip through struggle town.
After making our journey from Flux to Redux, we were happy with how clean and simple our state management had become so we kept ticking along.
