Server Driven UI
In a traditional mobile app development cycle, every changes or new feature requires to go through app store release, which may take days. Even when the app is released, there is no guarantee that user will update it. This creates a cycle where improvements and bug fixes take much longer than necessary.
With Server-Driven UI (SDUI) development, the server sends both the content and the design elements to the client and UI is rendered dynamically. The UI is generated based on the data provided by the server. This way tiny changes like text change, layout type can be easily managed from backend, without releasing new version.
Here is a simplified code illustration in React Native-
The data from the API response can be cached based on its version, eliminating the need to download it every time. Also, the response can be made more detailed if needed, including features like specifying the screen name or allowing nested child components within a parent component.
SDUI is not a one-size-fits-all solution, but it’s ideal for applications that needs frequent updates or high personalization.
You should avoid SDUI for apps with complex UI interactions like animations, real-time updates such as gaming applications, or simple, small-scale apps that rarely require updates.

The IKEA Effect: How LEGO and Spotify Drive User Engagement
The IKEA effect is basically when people love something more just because they made it themselves. The name IKEA comes from the Swedish furniture company, because they're famous for selling furniture that customers have to assemble themselves. People feel more competent when they make something on their own, it gives them a sense of pride and accomplishment.
Lego leverages the IKEA effect by encouraging customers to engage in hands-on assembly, following instructions, and adding their own creativity in the process. Additionally, Lego Ideas, where fans can submit designs for possible production, taps into this effect by making users part of the product creation journey.
Both Spotify and Tumblr uses the IKEA effect by enabling users to shape and personalize their experiences on the platforms. On Spotify, users can create their own playlist, spend time selecting songs for different mood and events, allowing them to craft something unique to them. Tumblr allows users design their blogs by choosing themes, colors, fonts, and layouts, making their Tumblr a true reflection of their personality. In both cases, users value these platforms more because they’ve put effort into making them personally meaningful and reflective of their tastes and identities.
