The Frustrating Reality of User Interfaces
Every day, we interact with numerous user interfaces (UIs) that shape our daily lives. From waking up to checking our schedules and social media, UIs are an integral part of our routines. However, most UIs have one thing in common: they’re plagued by bugs. The more complex the interface, the more bugs it tends to have. While these bugs may seem like minor inconveniences, they can quickly escalate into major frustrations.
The Root of the Problem: A Bad-Fit Development Approach
So, why do UI bugs persist despite decades of computer development? The answer lies in our approach to building UIs. We’re trying to predict how users will interact with our interfaces, but it’s a futile effort. Users can take multiple paths, and some of these paths lead to unintended behavior. These edge cases are the primary source of UI bugs.
The Limitations of Event-Driven Development
Event-driven development is a common approach to building UIs. It focuses on events, such as button clicks, and then checks the state to determine the outcome. However, this approach has significant drawbacks. It leads to code that doesn’t accurately represent the component’s intended behavior, and it entangles state logic with UI implementation. As a result, we end up with complex, hard-to-read code that’s prone to errors.
A Better Approach: State-Driven Development
State-driven development offers a promising alternative. It prioritizes states over events, giving users a defined group of events within a specific state. This approach makes UI code simpler, more scalable, and robust. With state-driven development, we can create more confidence in how our components will behave, separate concerns, and make testing easier.
The Advantages of State-Driven Development
State-driven development offers several benefits:
- Named states: Clear and understandable states make it easier to comprehend the component’s behavior.
- More confidence: By checking the state first, we gain more control over what the user can do.
- Separation of concerns: State logic is independent from UI implementation, making code more readable and easier to migrate.
- Easier testing: We can generate tests using the machine, reducing the need for mundane testing and catching more edge cases.
- Visualization: We can create interactive state charts that provide a clear understanding of the system.
A Brighter Future for UI Development
By adopting state-driven development, we can create UIs that are simpler, more scalable, and more robust. This approach has the potential to transform frustrating user experiences into pleasant ones.
