❓ Frequently Asked Questions

Q1: Which libraries should I prioritize for a new project in 2025?

A: For a new project in 2025, I recommend this priority order:

Immediate Essentials (Day 1):

i18n-ally - Even if you're starting with one language, future-proofing is crucial
Lenis - Easy 5-minute setup with immediate UX improvements

Core Features (Week 1): 3. Tiptap - If your project involves any content creation or editing 4. PDF.js - If you need document viewing capabilities

Advanced Features (Month 1): 5. XYFlow - For complex visual interfaces or workflow builders

Decision Matrix:

Content-heavy projects: Prioritize Tiptap + Lenis
International applications: Start with i18n-ally + PDF.js
Visual tools: Focus on XYFlow + Lenis
Enterprise applications: All five for comprehensive functionality

Q2: How do these libraries impact bundle size and performance?

A: Bundle size impact varies significantly:

Lightweight Libraries:

Lenis: 2.1KB - negligible impact
i18n-ally: VS Code extension - zero bundle impact

Medium Libraries:

Tiptap: 28KB (core) + extensions
XYFlow: 45KB (core) + custom nodes

Large Libraries:

PDF.js: 1.2MB - requires strategic loading

Optimization Strategies:

// Dynamic imports for large libraries
const loadPDF = () => import('pdfjs-dist').then(module => {
  // Initialize PDF.js only when needed
});

// Lazy loading XYFlow
const FlowBuilder = lazy(() => import('./FlowBuilder'));

// Tree shaking with Tiptap
import { Editor } from '@tiptap/core';
import StarterKit from '@tiptap/starter-kit';
// Only import needed extensions

Performance Best Practices:

Use code splitting by route
Implement lazy loading for PDF.js
Consider service worker caching
Monitor bundle size regularly
