I have made little functional progress on the project recently. I have focused on the foundation of the product.
Refactoring edit screens is rarely the most exciting part of development—but it’s often where complexity quietly grows. Over time, my UI layer became a mix of bindings, event handlers, validation logic, and lifecycle code scattered across multiple methods. It worked, but it wasn’t elegant, and more importantly—it wasn’t scalable.
So I decided to take a different approach: I built a small domain-specific language (DSL) to describe my edit screens declaratively.
The Shift: From Imperative to Declarative
Instead of wiring everything manually, my screens are now defined like this:
Form.For<Entity>()
.Section("General",
f => f.Text(x => x.Name).Required().Bind(this),
f => f.Editor(x => x.Description).Max(500).Bind(this)
)
.Build();
No more scattered bindings. No more duplicated validation logic. Everything lives in one place.
What Changed?
This DSL allowed me to unify several concerns:
UI definition
Data binding
Validation rules
Reactive behavior
All of it is now expressed fluently and consistently.
The Benefits
1. Clarity and Readability
Each screen now reads like a structured definition instead of a procedural script. You can understand what the form does at a glance.
2. Less Boilerplate
I removed a large amount of repetitive code: no more manual BindEntry, OnInitializeEntity, or event wiring everywhere.
3. Consistency Across the App
Every edit screen now follows the same pattern. That makes the codebase easier to navigate and reason about.
4. Built-in Validation
Validation rules like .Required(), .Min(), and .Max() are defined right next to the field they belong to—no more jumping between files.
5. Reactive by Design
With simple constructs like .Effect(...), I can react to changes in the model without adding complex event logic.
6. Extensibility
Need a new behavior? Add it once to the DSL, and it’s available everywhere. This has already paid off with features like ID binding and conditional visibility.
The Trade-off
This approach did cost me more time upfront.
Designing the DSL, refactoring existing screens, and solving edge cases (like mapping IDs to UI objects) wasn’t trivial. There were moments where the old way felt faster.
But that investment is already starting to pay off.
The Long-Term Payoff
Now that the foundation is in place:
Adding new screens is significantly faster
Changes are easier and safer to implement
The architecture is cleaner and more predictable
The UI layer finally feels like a system—not a collection of hacks
Most importantly, I’ve reduced cognitive load. I spend less time figuring out how things work and more time building features.
This DSL turned my edit screens from a maintenance burden into a structured, scalable system.
It wasn’t the quickest path—but it was the right one.
And I’m confident it will keep paying dividends as the application grows.
