ReactJS

Because technology moves fast, it’s easy to feel left behind. An old version of a JavaScript library is making your application perform slowly. You spend most of your time patching old code. Your UI looks like it was created years ago, but you don’t have time to update it.

Our team recently faced all these challenges when our 10-year-old product was using an old version of the Dojo toolkit. To migrate to the latest version of Dojo, we needed to rewrite the whole code with an asynchronous model. Our solution also needed to improve performance and provide a rich UI experience that complies with the IBM Carbon theme.

After a lot of research, we decided to use React JS instead of upgrading to a new version of Dojo. This blog post introduces ReactJS, highlights the research we did when comparing ReactJS with other JavaScript languages, and explains how we integrated ReactJS with our current Dojo library.

Solution: Our goal was to develop new pages with ReactJS and integrate them into our existing legacy Dojo application. We also needed to create reusable components of React in order to implement a single-page application quickly and migrate our whole application page-by-page in the long run.
