then coined “Isomorphic Ja*ascript”. The architecture seeks to achieve SEO, Performance and Maintainability for web applications. It uses Ja*aScript on the entire stack for the web client, and talks to an external service for data. This was a unique approach that solves one of the major pains of web development: Rendering markup in two different ways on the server and this blog post so that it may help those who are considering the same move. Like many companies, we initially wanted to adopt technologies already familiar to the rest of our engineers. Python was our language of This approach served us well for a while and we shipped a working website into the wild. As the source code grew, we started to have Our web server has mixed concerns of api duties, caching, and rendering of the user interface (UI). Often, when we require a bit of client-side routing (for a snappier interface), we ended up writing the same type of controllers and templates on Flask and Backbone.js. Writing views, controllers and filters in different languages and frameworks is unsurprisingly error Bootstrapping state from the server side to client side is not straightforward. The server should create the initial UI, and the frontend should take over and attach event handlers. This process is made more challenging when we have two different ways of rendering UI Too much context switching because of the different languages and frameworks involved. Naturally, we sought to unify the duties of rendering UI under a single language and framework to solve these problems. This forms a UI layer that consistently produce the same markup on the server and client side. Core to this design is a routing layer that maps pages to different routes. Each page request may fire a data fetching action and the results are then used to prerender markup on the server side. All navigation and interactions after the first page behaves like a Single Page Application (SPA), accu*ulating state through more data fetching and mutating markup on the fly.
