Five Things I Hate About React (And How to Overcome Them)

React has become the cornerstone of modern web development. With its declarative style and reusable component-based structure, it revolutionized how developers think about building interfaces. But no tool is flawless. As much as I appreciate React, there are certain frustrations that developers, including myself, often encounter when using it.

In this blog, I’ll dive deep into the five things I hate about React, explore why they’re problematic, and provide actionable solutions to tackle them. Whether you’re a seasoned developer or just starting out, there’s something here for everyone.

1. Steep Learning Curve for Beginners

React prides itself on being “just JavaScript,” but the reality for beginners is more complicated. Here’s why:

JSX Syntax: At first glance, JSX can look intimidating. Mixing HTML-like syntax with JavaScript feels unnatural to many new developers.
State and Props: Managing data flow between parent and child components requires understanding concepts like immutability and unidirectional data flow.
Hooks: While useState and useEffect are game-changers, they can overwhelm beginners who are still grappling with React basics.

Why This Matters

React is often marketed as beginner-friendly, but these complexities can discourage newcomers. If someone struggles early on, they might abandon it altogether.

Solutions

Start Simple

Focus on foundational concepts first. Begin with functional components, props, and simple state management. Avoid diving into hooks, context, or libraries like Redux until you’ve mastered the basics.
Resources for Learning
- Official React Docs: React’s new documentation is beginner-friendly with interactive examples.
- Courses: Platforms like Codecademy and Udemy have step-by-step React tutorials. Choose one that aligns with your learning style.
Practice Building Small Projects

Create to-do apps, simple blogs, or weather apps to get comfortable with React concepts. Start small before building larger projects.
Allais UI Generator

Use Allais UI Generator to scaffold pre-designed UI components. It’s a great way to focus on functionality without worrying about styling or structure, especially for beginners.

2. Boilerplate Everywhere

One of React’s greatest strengths—its flexibility—can also be a weakness. Setting up a React project often involves repetitive tasks like configuring routing, state management, and build tools. Even with modern tools like create-react-app and Vite, boilerplate can feel excessive.

Real-World Scenario

Imagine you’re starting a new React app. You’ll likely need to:

Install dependencies (react-router-dom, redux, etc.)
Create folder structures for components, styles, and assets.
Configure your app for routing, API calls, and state management.

For small projects, this setup feels like overkill. For large projects, it’s tedious.

Solutions

Use Starter Kits

Leverage starter kits that include pre-configured setups for routing, state management, and testing. Examples include:
- CRA (Create React App): A classic choice for beginners.
- Next.js: Ideal for production-ready apps with built-in routing and server-side rendering.
- Vite: Lightweight and fast for modern development.
Modularize Your Code

Create reusable modules for common functionalities like authentication or API services. This reduces redundancy and speeds up development.
Automate with Allais UI Generator

Allais UI Generator minimizes boilerplate by offering pre-configured templates compatible with React, Svelte, and Vue.js. This tool accelerates development, letting you focus on building rather than setting up.

3. Performance Optimization Can Be Tricky

React’s virtual DOM is a marvel, but optimizing apps for performance remains a challenge. Here are common issues developers face:

Unnecessary Re-Renders: Components re-rendering unnecessarily due to improper use of props or state.
Large Bundles: Including too many dependencies or failing to code-split can bloat your bundle size.
Inefficient State Management: Mismanaging state (e.g., keeping too much state in a top-level component) can hurt performance.

Why This Matters

Slow apps lead to poor user experiences, especially for users on slower devices or networks. Performance is critical in competitive markets.

Solutions

React Profiler

Use the React Profiler tool to identify components causing unnecessary re-renders.
Memoization

Use React.memo for functional components and useMemo or useCallback hooks to prevent unnecessary computations.

const MemoizedComponent = React.memo(MyComponent);

Code Splitting Use dynamic imports and tools like React.lazy and Suspense to split your code and load components only when needed.

const LazyComponent = React.lazy(() => import('./LazyComponent'));

Adopt Efficient State Management
Libraries like Zustand, Jotai, or React Query are often more lightweight than Redux and can improve state handling efficiency.
Leverage Tools
Tools like Allais UI Generator help you create optimized, pre-built UI components, reducing your workload.

4. Too Many Choices

React’s ecosystem is enormous. For every challenge, there’s an abundance of libraries claiming to solve it. While this diversity is empowering, it can also be paralyzing.

Real-World Scenario
Imagine you need to pick a state management library. Should you use Redux, MobX, Zustand, or Context API? Each has its pros and cons, and choosing the wrong one could create unnecessary headaches.

Why This Matters
Spending hours evaluating tools distracts from the actual work of building your app. Worse, the wrong choice could lead to costly refactors down the line.

Solutions

Stick to Proven Tools Don’t reinvent the wheel. Use well-documented libraries with active communities, such as:

Routing: React Router or Next.js routing.
State Management: React Query or Redux Toolkit.
UI Components: Allais UI Generator for cross-framework compatibility.
Evaluate Libraries Based on Needs
Ask yourself:
Does this library solve my problem?
Is it actively maintained?
Does it align with my project’s size and complexity?
Document Your Stack

Create a “technology stack” document for your project. This will serve as a reference for future decisions and onboarding new developers.

5. Frequent Updates and Breaking Changes

React’s fast-paced development can feel like a double-edged sword. While new features like Concurrent Mode and Server Components are exciting, keeping up with updates can be exhausting.

Real-World Scenario
You’ve just upgraded to the latest version of React, only to find that your app’s tests are breaking because of changes in a popular library.

Why This Matters
Frequent updates require constant learning and maintenance. This can be particularly challenging for teams with tight deadlines or legacy codebases.
Solutions

Stay Updated Gradually
Don’t upgrade React or its dependencies the moment new versions are released. Wait for community feedback and updated documentation.
Use LTS Versions
Focus on long-term support (LTS) versions of dependencies to minimize breaking changes.
Monitor Release Notes
Follow the React blog and GitHub release notes to understand changes before updating your projects.
Build Scalable UI with Allais UI Generator
Tools like Allais UI Generator provide future-proof templates that align with the latest best practices in React, Svelte, and Vue.js.
