Choosing the Right Framework: Vanilla JS, React, or React+TypeScript

Three Frameworks, Different Strengths

GenMB can generate apps in Vanilla JavaScript, React, or React + TypeScript. Each has its place. Here's how to choose.

Vanilla JavaScript

Best for:

• Simple, single-purpose apps
• Maximum performance needs
• Minimal bundle size
• Static sites with light interactivity

Examples:

• Calculators and converters
• Simple games
• Landing pages
• Utility tools

Prompt tip:

"Create a unit converter using vanilla JavaScript for fastest performance"

Pros:

• Fastest load times
• No framework overhead
• Simplest mental model
• Works everywhere

Cons:

• Manual DOM manipulation
• Harder to manage complex state
• Less structure for large apps

React

Best for:

• Complex, stateful applications
• Apps with many interactive components
• Projects that may grow in scope
• Familiar patterns for most developers

Examples:

• Dashboards
• E-commerce interfaces
• Social media-style feeds
• Multi-page applications

Prompt tip:

"Build a task management dashboard using React with component-based architecture"

Pros:

• Excellent state management
• Component reusability
• Large ecosystem
• Industry standard

Cons:

• Larger bundle size
• Learning curve for JSX
• More boilerplate

React + TypeScript

Best for:

• Professional, production-grade applications
• Teams that value type safety
• Large codebases that need maintainability
• Apps with complex data structures

Examples:

• Enterprise dashboards
• SaaS applications
• Complex forms with validation
• Apps with API integrations

Prompt tip:

"Create a customer management app using React with TypeScript for type safety"

Pros:

• Catch errors at compile time
• Better IDE autocomplete and refactoring
• Self-documenting code
• Easier maintenance as apps grow

Cons:

• Slightly more verbose
• Learning curve for TypeScript
• Larger bundle than plain React

Quick Decision Guide

Framework Comparison by Feature

State Management

• Vanilla JS: Manual (variables, localStorage)
• React: useState, useReducer, Context
• React + TS: Same as React, with typed state

Component Structure

• Vanilla JS: Functions and classes
• React: JSX components
• React + TS: Typed JSX components with interfaces

Learning Curve

• Vanilla JS: Low (just JavaScript)
• React: Medium (JSX, hooks)
• React + TS: Medium-High (JSX, hooks, TypeScript)

Type Safety

• Vanilla JS: None (runtime errors only)
• React: None (unless using PropTypes)
• React + TS: Full compile-time type checking

When in Doubt

If you're unsure, here's the default recommendation:

• Simple app (< 5 features): Vanilla JS
• Medium app (5-15 features): React
• Complex/production/enterprise app: React + TypeScript

Or just ask GenMB:

"I want to build [describe app]. Which framework would you recommend?"

The AI will suggest the best fit based on your requirements.

Switching Frameworks

Already generated an app but want to try a different framework?

"Recreate this app using React instead of Vanilla JS"

GenMB will rebuild with the new framework while maintaining your features.

Choose wisely, but don't overthink it—you can always regenerate.
