Better development stack
Ushahidi 3.x is built on a modern PHP stack: dependencies are managed with composer, we’re using Kohana 3 but phasing that out, and we’ve isolated the core logic of the platform standalone Entity and Usecase classes.
The user interface of Ushahidi 3.x is now a separate app (the client) built purely in JS, HTML + CSS using AngularJS and a collection of other libraries. Again this uses a modern stack, with a build pipeline using gulp and browserify.
What’s new (and improved)?
Dependencies are properly managed and easier to update or replace needed.
We’re using our own API to build the app, it gets first class support.
You can work on just the UI without delving into the API code
Modern libraries mean they’re still being supported, we don’t have the burden of supporting legacy libraries ourselves.
Code is easier to customize
It’s more structured making it easier to find what you want
It doesn’t repeat itself so a change can be made in one place, not need to be copied everywhere else
UI is isolated to the client, allowing work on just the UI without having to delve into the API code
