Front-end development engineer core learning architecture (lite version)

1. Basic core layer (must be proficient)

  1. Basic three-piece set
    • HTML5: Semantic tags, Accessibility (ARIA), SEO optimization.
    • CSS3: Flex/Grid layout, animation, responsive design (media query, Viewport adaptation).
    • JavaScript (ES6+): modular, asynchronous programming (Promise/Async), prototype chain, closure, memory management.
  2. Modern Framework and Type Safety
    • Vue 3 + Composition API: Responsive principle (Proxy/Reflect), component communication, Pinia state management.
    • TypeScript: type system, generics, tool types (Utility Types), engineering integration.
  3. Network and protocol
    • HTTP/HTTPS: Cache policy (strong cache/negotiation cache), cross-domain (CORS/JSONP), HTTPS handshake process.
    • RESTful API: Design specifications, debugging tools (Postman/Thunder Client).

2. Engineering and performance layer (deep mastery)

  1. Build and deploy
    • Webpack/Vite: Configuration optimization (code segmentation, Tree Shaking), plug-in development (Loader/Plugin).
    • CI/CD: GitHub Actions/Vercel automation deployment, Docker containerization.
  2. Performance optimization
    • Core indicators: Lighthouse analysis (FCP/LCP/CLS), first-screen loading optimization (SSR/SSG).
    • Resource management: Lazy image loading (Intersection Observer), format compression (WebP/AVIF), CDN acceleration.
  3. Safety protection
    • Attack Defense: XSS (Input Filtering/CSP), CSRF (Token Verification), SQL Injection (ORM Protection).
    • Dependency security: npm audit/Snyk vulnerability scanning, dependency version lock ().

3. Multi-end development layer (in-depth on demand)

  1. Mobile adaptation
    • Responsive development: dynamic REM schemes, touch events (Tap/Swipe), 1px border issues.
    • Performance Tuning: Reduce redraw and reordering, Web Workers multi-threading, offline caching (Service Worker).
  2. Cross-end technology
    • Mini Program: Taro/UniApp multi-terminal development, native API calls (WeChat Payment/Geolocation).
    • Desktop application: Electron main process communicates with the rendering process and operates local files.

4. Frontier architecture layer (differentiated competitiveness)

  1. High-performance architecture
    • Islands architecture: Partial Hydration mode of Astro/Qwik, server-side rendering is preferred.
    • Micro front-end: qiankun/Module Federation realizes module splitting and independent deployment.
  2. Visualization technology
    • 3D development: Core (scene/camera/lighting), Shader programming (GLSL).
    • Map development: Mapbox vector tile, Cesium terrain rendering (GeoJSON data processing).
  3. WebAssembly integrates with AI
    • Rust + Wasm: High-performance module development (audio and video decoding), interoperating with JS.
    • AI native applications: LangChain calls, large model front-end display layer optimization (RAG search enhancement).

5. Expand the technology stack (enhance breadth)

  1. Server-side basics
    • : Express middleware, NestJS hierarchical architecture, SSR framework ().
  2. Edge computing
    • Serverless function: Vercel/Cloudflare Workers implements global low-latency distribution.
  3. Testing and quality
    • Unit Test: Jest/Vitest Coverage Optimization.
    • E2E Test: Cypress/Playwright simulates user behavior.

Summary: Learning Path and Priority

  1. Core path
    Basic three-piece set → Vue/TS → Engineering tools → Performance optimization → Mobile adaptation
    (60% energy)
  2. Differentiated breakthrough
    Islands Architecture → WebAssembly → 3D Visualization → AI Integration
    (30% energy)
  3. Extended Supplement
    Server-side basics → Edge computing → Test capabilities
    (10% energy)
