# Code Splitting Helper

## Overview

This skill provides automated assistance for code splitting helper tasks within the Frontend Development domain.

## When to Use

This skill activates automatically when you:
- Mention "code splitting helper" in your request
- Ask about code splitting helper patterns or best practices
- Need help with frontend skills covering react, vue, css, accessibility, performance optimization, and modern web development patterns.

## Instructions

1. Provides step-by-step guidance for code splitting helper
2. Follows industry best practices and patterns
3. Generates production-ready code and configurations
4. Validates outputs against common standards

## Examples

**Example: Basic Usage**
Request: "Help me with code splitting helper"
Result: Provides step-by-step guidance and generates appropriate configurations


## Prerequisites

- Relevant development environment configured
- Access to necessary tools and services
- Basic understanding of frontend development concepts


## Output

Overview

This skill automates guidance and configuration for code splitting helper tasks in frontend projects. It focuses on practical, production-ready code splitting patterns to improve load performance and maintainability. Use it to generate configurations, validate outputs, and get step-by-step implementation advice for frameworks like React and Vue.

How this skill works

The skill inspects your project context and requested target (framework, bundler, or runtime) and produces tailored code split strategies and configuration snippets. It generates lazy-loading patterns, route-based splitting, bundle analysis commands, and CI-friendly validation steps. Outputs include ready-to-drop code, recommended tooling commands, and checks against common performance and accessibility standards.

When to use it

  • When you want to implement route-based or component-level lazy loading in React or Vue
  • When optimizing initial load time, reducing bundle size, or enabling long-term caching
  • When creating or updating bundler configs for Webpack, Rollup, or Vite
  • When validating code splitting correctness and bundle content after builds
  • When you need production-ready examples and CI checks for code splitting

Best practices

  • Prefer route-based splitting for large pages and component-level splitting for heavy widgets
  • Keep split boundaries logical to avoid duplicate dependencies across chunks
  • Use dynamic imports with explicit chunk names when needed for easier debugging
  • Analyze bundles with tools like source-map-explorer or webpack-bundle-analyzer
  • Add runtime fallbacks and loading states to maintain UX during lazy loads

Example use cases

  • Add React.lazy and Suspense patterns for a multi-page app and generate Webpack dynamic import config
  • Create route-based code splitting for a Vue Router app with async components and prefetch hints
  • Produce a build-time bundle analysis script and a CI check that fails on size regressions
  • Migrate a monolithic entry to multiple async entries with caching-friendly filenames
  • Suggest accessibility-safe loading placeholders and focus management during lazy loads

FAQ

Which bundlers and frameworks does this support?

Common frameworks and bundlers including React, Vue, Webpack, Vite, and Rollup are supported via tailored snippets and patterns.

Will it change my project files automatically?

It generates ready-to-apply code and configuration suggestions. You apply changes manually or integrate them into automation pipelines.

How does it validate outputs?

Validation includes recommended bundle analysis commands, simple heuristics for duplicate modules, and checks against common performance thresholds.
