Clean Architecture is Not a Shower for Your Codebase

Alright kids, gather ‘round. Let me tell you the tale of Clean Architecture—that magical spell developers cast on their codebase, hoping it’ll turn into a well-oiled, unicorn-powered machine.

But plot twist: sometimes it turns into a Frankenstein monster with too many interfaces, layers of abstraction thicker than grandma’s lasagna, and a team screaming “YAGNI!” like it’s a battle cry.

Let’s dive into why Clean Architecture is great... but not the silver bullet we hoped it’d be.

What is Clean Architecture?

If you’re new to this world, here’s a quick primer. Clean Architecture is an approach to structuring software projects with layers:

• Entities (aka your pure domain models)
• Use Cases / Interactors (business logic)
• Interface Adapters (converts data for the UI or frameworks)
• Frameworks & Drivers (databases, web stuff, devices—"the outer circle")

Sounds tidy, right? Like a Marie Kondo’d codebase.

And that’s the idea. You separate concerns, make your codebase testable, independent from frameworks, and scalable. Chef’s kiss. But like all good things in software...

The Problems Begin...

1. Layer Cake Hell (aka “Abstraction for Abstraction’s Sake”)

Clean architecture introduces layers. But sometimes those layers become so nested it feels like you're navigating the Inception of codebases.

Example:

interface IUserRepository { ... }
class UserRepository : IUserRepository { ... }
interface IUserService { ... }
class UserService : IUserService { ... }
interface IUserController { ... }
class UserController : IUserController { ... }

And all this just to get a dang user profile?

"Ah yes, the cleanest way to write one line of logic... is with 42 interfaces and a ritual sacrifice to the Dependency Injection gods."

Why it happens: Developers often mistake "Clean" for "Make it as abstract and decoupled as possible even if it’s only used once."

Lesson: You don’t always need every layer for every feature. Clean ≠ Complex. Don’t be afraid to simplify.

2. Premature Architecture-ization™

You're building a to-do list app. It has one screen. One button. But you implemented Clean Architecture like you’re scaling Netflix.

You now have:

• Domain layer with abstract TaskManager logic
• Use case AddTaskUseCase
• Interface adapters with a presenter
• Firebase implementation in the data layer

“Sir, this is a Wendy’s.”

Why it’s a problem: Clean Architecture’s biggest enemy is overengineering, especially in MVPs or solo-dev projects.

Lesson: Architecture is not a flex. It's a tool. Build what you need, when you need it.

3. Hard to Onboard New Devs (“The Maze Runner: Clean Arch Edition”)

New devs: “Where is the actual logic?”

Veteran devs: “You need to go to the Interactor, then the Gateway, then the Adapter, then summon the interface spirit with a Factory before you touch the Repository.”

It’s like playing a text-based RPG just to read a user from the DB.

Why it sucks: Clean Architecture can make the learning curve for your project steep AF. Especially when team members are juniors or new to the codebase.

Lesson: Complexity is only worth it when it actually adds value. Otherwise, you’re building an ivory tower no one can live in.

4. Testing Utopia… or so we thought.

One of the big selling points: “Clean architecture makes unit testing so easy!”

And yes... BUT.

When you’ve got 10 layers and mock everything, your tests start to look like you’re testing the mocks instead of the app.

Example:

when(mockUserRepository.getUser()).thenAnswer(...);
when(mockUseCase.execute()).thenReturn(...);

You run the test and it passes. But nothing real got tested. It's a fake city of fake people living fake lives. (Welcome to Mocksville, population: lies.)

Lesson: Mocking everything to test one thing often just tests... mocking. Consider where integration or functional tests are better.

5. Doesn’t Play Well With Some Frameworks

Frameworks like Flutter, React, or even Django have opinions.

You know, like that one friend who “doesn’t like pineapple on pizza” and won’t shut up about it.

These frameworks often have built-in patterns and conventions. Trying to force Clean Architecture into their mold can result in:

• Fighting the framework
• Too many wrappers
• Having 50% boilerplate, 50% glue code

Example: In Flutter, putting every little logic into use cases and repositories might slow you down, especially for UI-focused features.

Lesson: Respect the framework’s conventions. Marry them with Clean Architecture where it makes sense.

6. Slower Development Speed (Especially in Small Teams)

When every small change means touching 5 files across 3 layers with 2 DI bindings... productivity dips.

For startups or solo devs, that overhead adds up faster than bugs in legacy PHP code.

You wanted to change a button’s behavior.
Now you're refactoring a use case, updating an interface, injecting a new service, and wondering why you chose this life.

Lesson: Clean is good. But pragmatism is better. Favor development velocity over perfect structure in early stages.

7. Cargo Culting Clean Architecture

Some devs follow it religiously, without understanding the why.

“Because Uncle Bob said so!”

That’s how you end up with classes like:

LoginUseCaseImplAdapterProxyFactory

...and no one knows what it does.

Lesson: Clean Architecture is a guideline, not a gospel. Think critically. Adapt, don’t adopt blindly.

So... Is Clean Architecture Bad?

Absolutely not. In fact, it’s awesome when:

• Your project is large-scale or growing
• You need clear separation of concerns
• You want maintainability and testability
• You have multiple devs, teams, or shared components
• You enjoy structure more than chaos (good for you, you star!)

But Clean Architecture is not a one-size-fits-all. It’s like trying to wear a three-piece suit to the beach. Sure, you can—but should you?

The Balanced Way Forward

Here’s how to be smart with Clean Architecture:

1. Start dirty, clean as you go.
   MVPs don’t need a cathedral. A shack will do.

2. Only abstract when there’s more than one implementation.
   One IUserRepository with one implementation? Not needed yet.

3. Understand your app’s real complexity.
   Not every project is a bank transaction system.

4. Think in “useful layers,” not “maximum layers.”
   Let your layers be meaningful, not ritualistic.

5. Use Clean Arch principles, not dogma.
   You can borrow ideas like dependency inversion, separation of concerns, etc., without doing the whole dance.

TL;DR

• Clean Architecture is powerful.
• But misused, it’s a trap.
• Think before you abstract.
• Respect your app’s context.
• Balance purity with pragmatism.

Final Words

Clean Architecture is like salad. Healthy, crisp, full of benefits... but if you put too much kale and not enough dressing, no one’s gonna eat it.

So, keep it clean—but keep it real.
