Eager Loading vs Lazy Loading

Developers should use eager loading when building applications that require efficient data retrieval for related entities, such as in web APIs, reporting tools, or data-intensive dashboards meets developers should use lazy loading when building applications with large datasets, media-heavy content, or complex user interfaces to enhance performance and user experience. Here's our take.

Eager Loading

Nice Pick

Developers should use eager loading when building applications that require efficient data retrieval for related entities, such as in web APIs, reporting tools, or data-intensive dashboards

Pros

• It is particularly beneficial in scenarios where you know in advance that related data will be needed, such as displaying a list of blog posts with their comments or user profiles with associated orders
• Related to: object-relational-mapping, database-optimization

Cons

• Specific tradeoffs depend on your use case

Lazy Loading

Developers should use lazy loading when building applications with large datasets, media-heavy content, or complex user interfaces to enhance performance and user experience

Pros

• It is particularly useful in web development for loading images, videos, or JavaScript modules only when they become visible in the viewport, reducing bandwidth and speeding up page loads
• Related to: code-splitting, dynamic-imports

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Eager Loading if: You want it is particularly beneficial in scenarios where you know in advance that related data will be needed, such as displaying a list of blog posts with their comments or user profiles with associated orders and can live with specific tradeoffs depend on your use case.

Use Lazy Loading if: You prioritize it is particularly useful in web development for loading images, videos, or javascript modules only when they become visible in the viewport, reducing bandwidth and speeding up page loads over what Eager Loading offers.

The Bottom Line

Eager Loading wins

Developers should use eager loading when building applications that require efficient data retrieval for related entities, such as in web APIs, reporting tools, or data-intensive dashboards
