Server-driven UI continues to be a hot topic of discussion in mobile circles because it offers the potential for developers to take advantage of faster change cycles without falling foul of an app store's policies around revalidation of the mobile app itself. Server-driven UI separates the rendering into a generic container in the mobile app while the structure and data for each view is provided by the server. This means that changes that once required a round trip to an app store can now be accomplished via simple changes to the responses the server sends. While some very large mobile app teams have had great success with this technique, it also requires a substantial investment in building and maintaining a complex proprietary framework. Such an investment requires a compelling business case. Until the case is made, it might be best to proceed with caution; indeed, we've experienced some horrendous, overly configurable messes that didn't actually deliver on the promised benefits. But with the backing of behemoths such as Airbnb and Lyft, we may very well see some useful frameworks emerge that help tame the complexity. Watch this space.
When putting together a new volume of the Radar, we're often overcome by a sense of déjà vu, and the technique of server-driven UI sparks a particularly strong case with the advent of frameworks that allow mobile developers to take advantage of faster change cycles while not falling foul of an app store's policies around revalidation of the mobile app itself. We've blipped about this before from the perspective of enabling mobile development to scale across teams. Server-driven UI separates the rendering into a generic container in the mobile app while the structure and data for each view is provided by the server. This means that changes that once required a round trip to an app store can now be accomplished via simple changes to the responses the server sends. Note, we're not recommending this approach for all UI development, indeed we've experienced some horrendous, overly configurable messes, but with the backing of behemoths such as AirBnB and Lyft, we suspect it's not only us at Thoughtworks getting tired of everything being done client side. Watch this space.
