Overview

Implement scalable pagination strategies for handling large datasets with efficient querying, navigation, and performance optimization.

When to Use

• Returning large collections of resources
• Implementing search results pagination
• Building infinite scroll interfaces
• Optimizing large dataset queries
• Managing memory in client applications
• Improving API response times

Quick Start

Minimal working example:

// Node.js offset/limit implementation
app.get('/api/users', async (req, res) => {
  const page = parseInt(req.query.page) || 1;
  const limit = Math.min(parseInt(req.query.limit) || 20, 100); // Max 100
  const offset = (page - 1) * limit;

  try {
    const [users, total] = await Promise.all([
      User.find()
        .skip(offset)
        .limit(limit)
        .select('id email firstName lastName createdAt'),
      User.countDocuments()
    ]);

    const totalPages = Math.ceil(total / limit);

    res.json({
      data: users,
      pagination: {
        page,
        limit,
        total,
        totalPages,
        hasNext: page < totalPages,
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Use cursor pagination for large datasets
• Set reasonable maximum limits (e.g., 100)
• Include total count when feasible
• Provide navigation links
• Document pagination strategy
• Use indexed fields for sorting
• Cache pagination results when appropriate
• Handle edge cases (empty results)
• Implement consistent pagination formats
• Use keyset for extremely large datasets

❌ DON'T

• Use offset with billions of rows
• Allow unlimited page sizes
• Count rows for every request
• Paginate without sorting
• Change sort order mid-pagination
• Use deep pagination without cursor
• Skip pagination for large datasets
• Expose database pagination directly
• Mix pagination strategies
• Ignore performance implications
