React Folder Component Architecture: A C# Developer’s Perspective
As a C# developer, organizing code in a clear, scalable way is familiar—whether using layered architectures like MVC or modular patterns. React’s component-based approach offers similar goals but requires adapting to a different mindset. Here’s how React folder structures work, whether Next.js’s opinionated setup is ideal, and options to consider. React Component Architecture Basics In React, components are reusable building blocks (like C# classes or Razor components). However, structuring them can feel chaotic without guidelines. Common approaches include: Grouping by File Type - /src - /components (e.g., Button, Header) - /pages (e.g., HomePage, ProfilePage) - /hooks (custom hooks) - /utils (helper functions) Pros: Simple, easy for small projects. Cons: Hard to scale; components lack context (like grouping unrelated C# models and controllers). Feature-Based Folders - /src - /features - /authentication - components (LoginForm, SignupButton) - hooks (useAuth) - /dashboard - components (Chart, StatsPanel) Pros: Logical grouping (similar to C# modules or vertical slices). Easier maintenance. Cons: Risk of duplication (e.g., reusable buttons buried in features). Atomic Design Split components into atoms (smallest UI pieces), molecules, organisms, etc. Pros: Encourages reusability (like C# base classes). Cons: Overkill for simple apps; rigid for dynamic features. Is Next.js’s Opinionated Structure the Best Choice? Next.js enforces conventions like /pages or /app for routing, which can feel familiar to C# developers used to MVC’s predefined structures. Pros: Built-in Routing: Automatic page routing (like ASP.NET Core’s endpoint mapping). Optimization: Server-side rendering (SSR), static site generation (SSG)—similar to Razor Pages but for React. Less Configuration: Focus on features, not setup (like .NET templates). Cons: Flexibility Limits: Hard to customize if your project needs unique routing or state logic. Learning Curve: New concepts (e.g., Server Components) require time. When to Choose Next.js: Full-stack apps needing SEO-friendly rendering. Teams valuing convention over configuration (like using ASP.NET Core’s defaults). Recommended Structure for C# Developers A hybrid approach works well for most projects: - /src - /components - /ui (reusable atoms: buttons, inputs) - /features (feature-specific components) - /lib (C#-like utilities, API clients) - /hooks (global hooks like useFetch) - /pages or /app (Next.js routing) Pros: Balances reusability and feature context. Feels intuitive if you’re used to layered .NET architectures. Cons: Requires discipline to avoid mixing UI and logic. Conclusion Next.js’s opinionated structure is excellent for full-stack apps requiring SSR/SSG, much like ASP.NET Core simplifies backend logic. However, for smaller projects or teams wanting full control, a custom React setup with feature-based folders might be better. As a C# developer, lean on patterns you know—modularity, separation of concerns—and adapt them to React’s component-driven world.

React Component Architecture Basics
In React, components are reusable building blocks (like C# classes or Razor components). However, structuring them can feel chaotic without guidelines. Common approaches include:
- Grouping by File Type
- /src
- /components (e.g., Button, Header)
- /pages (e.g., HomePage, ProfilePage)
- /hooks (custom hooks)
- /utils (helper functions)
Pros: Simple, easy for small projects.
Cons: Hard to scale; components lack context (like grouping unrelated C# models and controllers).
- Feature-Based Folders
- /src
- /features
- /authentication
- components (LoginForm, SignupButton)
- hooks (useAuth)
- /dashboard
- components (Chart, StatsPanel)
Pros: Logical grouping (similar to C# modules or vertical slices). Easier maintenance.
Cons: Risk of duplication (e.g., reusable buttons buried in features).
- Atomic Design Split components into atoms (smallest UI pieces), molecules, organisms, etc. Pros: Encourages reusability (like C# base classes). Cons: Overkill for simple apps; rigid for dynamic features.
Is Next.js’s Opinionated Structure the Best Choice?
Next.js enforces conventions like /pages or /app for routing, which can feel familiar to C# developers used to MVC’s predefined structures.
Pros:
- Built-in Routing: Automatic page routing (like ASP.NET Core’s endpoint mapping).
- Optimization: Server-side rendering (SSR), static site generation (SSG)—similar to Razor Pages but for React.
- Less Configuration: Focus on features, not setup (like .NET templates).
Cons:
- Flexibility Limits: Hard to customize if your project needs unique routing or state logic.
- Learning Curve: New concepts (e.g., Server Components) require time.
When to Choose Next.js:
- Full-stack apps needing SEO-friendly rendering.
- Teams valuing convention over configuration (like using ASP.NET Core’s defaults).
Recommended Structure for C# Developers
A hybrid approach works well for most projects:
- /src
- /components
- /ui (reusable atoms: buttons, inputs)
- /features (feature-specific components)
- /lib (C#-like utilities, API clients)
- /hooks (global hooks like useFetch)
- /pages or /app (Next.js routing)
Pros:
- Balances reusability and feature context.
- Feels intuitive if you’re used to layered .NET architectures.
Cons:
- Requires discipline to avoid mixing UI and logic.
Conclusion
Next.js’s opinionated structure is excellent for full-stack apps requiring SSR/SSG, much like ASP.NET Core simplifies backend logic. However, for smaller projects or teams wanting full control, a custom React setup with feature-based folders might be better. As a C# developer, lean on patterns you know—modularity, separation of concerns—and adapt them to React’s component-driven world.
