API-First SaaS 2.0 Single Page Apps

Two of the core components of SaaS 2.0 products are actually related: API-first platform and rich, responsive user interfaces. Ever since Gmail made the first mainstream Javascript-heavy web experience that feels more like a desktop app, developers have been building open source platforms to make that type of “Single Page App” easier and faster to build. Single Page Apps reload only the portions of the screen that have changed, instead of the traditional way which refreshed the whole screen. And, these Single Page Apps work best against REST APIs, the same APIs that make a product API-first.

Now, there are powerful Javascript libraries like Angular (MVC framework backed by Google) and React (view framework backed by Facebook) that are popular with strong developer communities and a long list of additional open source projects that plug in nicely. By having quality, proven open source platforms, more apps are going to adopt them thereby applying more pressure to the legacy incumbents. The incumbents are going to have an incredibly hard time modernizing. Just like many software companies couldn’t make the transition from on-premise to the cloud, many SaaS companies aren’t going to be able to make the transition from SaaS 1.0 to SaaS 2.0, and it’ll be most apparent in the user experience.

Look for Single Page Apps to be a defining characteristic of API-first SaaS 2.0 companies.
