Frontend Frameworks & Libraries

Frontend frameworks and libraries are essential tools that accelerate UI development and standardize application architecture across web and mobile platforms. The landscape shows React's dominance in web development, appearing in >40% of Frontend Development positions, while Angular maintains strong enterprise presence (>30%). Mobile development is increasingly framework-driven, with React Native enabling cross-platform development across iOS Development and Android Development roles (>10% each), while Flutter emerges as a strong alternative. Native mobile frameworks like SwiftUI, UIKit, and Jetpack Compose show high specialization within their respective platforms. Modern meta-frameworks like Next.js are rapidly growing (>5% prevalence) for server-side rendering and full-stack capabilities. UI libraries like Tailwind CSS and Bootstrap accelerate styling workflows. Entry-level positions strongly emphasize React and React Native, with >35% of entry-level frontend roles requiring React experience. Framework expertise significantly influences specialization paths, with choices between native performance and cross-platform efficiency shaping career trajectories.

Web Application Frameworks

Core frameworks for building modern web applications with component-based architectures. React leads the ecosystem with exceptional market penetration across Frontend Development positions, followed by Angular in enterprise contexts and Vue as a progressive alternative. These frameworks define the modern web development landscape and offer strong entry-level opportunities.

React

Vue.js

Moderate Demand
Rank: #3
Entry-Level: Low
Progressive framework in Frontend Development (>10% prevalence) valued for its approachability and flexibility. Lower entry-level presence but growing. Used for building user interfaces incrementally, smaller to medium web applications, projects requiring gentle learning curve, and integrating into existing projects gradually.

jQuery

Low Demand
Rank: #4
Entry-Level: Low
Legacy presence in Frontend Development (>5% prevalence), primarily for maintaining older codebases. Declining demand with limited entry-level opportunities. Still used for legacy application maintenance, simple DOM manipulation in older projects, and working with existing jQuery-based systems.

Svelte

Low Demand
Rank: #5
Entry-Level: Low
Emerging modern framework with limited but growing presence in Frontend Development (<5% prevalence). Minimal entry-level demand currently. Used for performance-critical web applications, projects valuing small bundle sizes, and modern development with compile-time optimization rather than virtual DOM.

State Management & Meta-Frameworks

Tools for managing application state and extending framework capabilities. Redux remains the standard for React state management in Frontend Development roles, while Next.js represents the growing trend toward full-stack React frameworks with server-side rendering capabilities. These tools are critical for complex application development.

Redux

High Demand
Rank: #1
Entry-Level: Moderate
Primary state management library for React in Frontend Development (>10% prevalence). Moderate entry-level demand with >10% of entry-level positions mentioning it. Used for managing complex application state, predictable state containers, centralized data flow in large React applications, and coordinating state across multiple components.

Next.js

Moderate Demand
Rank: #2
Entry-Level: Low
Rapidly growing React meta-framework in Frontend Development (>5% prevalence). Lower but increasing entry-level demand with >5% prevalence. Used for server-side rendering, static site generation, full-stack React applications, SEO-optimized web apps, and building production-ready React applications with routing and API routes.

Cross-Platform Mobile Frameworks

Frameworks enabling code sharing across iOS and Android platforms. React Native and Flutter dominate cross-platform development, appearing significantly in both iOS Development and Android Development roles. These frameworks offer compelling alternatives to native development, with strong entry-level markets for developers seeking multi-platform capabilities.

React Native

High Demand
Rank: #1
Entry-Level: Moderate
Leading cross-platform framework in iOS Development (>15%) and Android Development (>10%). Also present in Frontend Development (>5%). Moderate entry-level demand with >10% prevalence across mobile roles. Leverages JavaScript/React knowledge for native mobile apps. Used for building iOS and Android apps from single codebase, rapid mobile prototyping, and leveraging web development skills for mobile.

Flutter

Moderate Demand
Rank: #2
Entry-Level: Moderate
Google's cross-platform framework in iOS Development (>10%) and Android Development (>5%). Moderate entry-level presence with >10% prevalence in mobile development. Uses Dart language. Used for building beautiful native interfaces across platforms, high-performance mobile apps, custom UI designs, and applications requiring consistent look across iOS and Android.

Native Mobile Frameworks

Platform-specific frameworks for iOS and Android development. These frameworks show high specialization within their ecosystems, with SwiftUI modernizing iOS Development workflows while UIKit remains essential for legacy support. Jetpack Compose represents Android's declarative UI future for Android Development roles.

SwiftUI

High Demand
