Sample Guide​

docs/guides/pagination.mdx:

---
title: "Pagination Guide"
description: "Handle large datasets with pagination"
sidebar_position: 1
---

# Pagination

APIs return large datasets. Pagination reduces payload and improves performance.

## Skip and Take

Use \`skip\` and \`take\` parameters:

\`\`\`bash
GET /api/students?skip=0&take=10    # First 10 records
GET /api/students?skip=10&take=10   # Next 10 records
GET /api/students?skip=20&take=10   # Third batch
\`\`\`

Response includes total count:

\`\`\`json
{
  "data": [ ... 10 students ... ],
  "total": 245,
  "page": 1
}
\`\`\`

## Implementation

Calculate pages:

\`\`\`typescript
const pageSize = 10;
const total = 245;
const totalPages = Math.ceil(total / pageSize);

// Get page N (1-indexed)
function getPage(page: number) {
  const skip = (page - 1) * pageSize;
  return fetch(\`/api/students?skip=\${skip}&take=\${pageSize}\`);
}

getPage(1);  // Records 0-9
getPage(2);  // Records 10-19
getPage(3);  // Records 20-29
\`\`\`

Building and Deploying​

# Install dependencies
npm install

# Development
npm start         # http://localhost:3000

# Build
npm run build     # Creates 'build' folder

# Deploy to GitHub Pages
npm run deploy

# Deploy to Vercel
# Connect GitHub repo to Vercel
# Auto-deploys on push

Key Patterns​

  1. Getting Started — Auth, first request, basics
  2. API Reference — One page per endpoint/resource
  3. Guides — How-tos (pagination, filtering, error handling)
  4. Examples — Complete workflows (student enrollment, exam management)
  5. Code tabs — Show examples in multiple languages

Key Takeaways​

  • Organize docs in logical folders (getting-started, api, guides, examples)
  • Each API endpoint = separate page
  • Use tabs for multi-language examples
  • Provide curl, SDK, JavaScript examples
  • Error responses clearly documented
  • Guides for common tasks and patterns
  • Sidebar structure mirrors documentation organization
  • Deploy to Vercel/GitHub Pages for free
💡 Backend Developer Tip

Good API documentation = fewer support questions. Docusaurus makes it easy to maintain. Update docs when you update API. Version docs alongside API versions.

⚠️ Documentation Best Practices
  1. Keep updated — Outdated docs worse than no docs
  2. Show examples — In multiple languages/frameworks
  3. Document errors — What can go wrong and why
  4. Use consistent format — All endpoints documented same way
  5. Include full URLs — Not relative paths
  6. Add response codes — 200, 400, 401, 404, 500
🤖Use AI to Learn Faster

Use ChatGPT, Claude, or Copilot to go deeper on SMS Documentation. Try these prompts:

  • "How do you structure large API documentation?"
  • "Why show code examples in multiple languages?"
  • "What goes in a complete API endpoint page?"
  • "Quiz me on Docusaurus best practices"

💡 Tip: After reading this article, paste your own code into AI and ask "What could go wrong here and why?" — fastest way to find edge cases and deepen understanding.
