What are the best practices for data preloading in web applications?

What are the best practices for data preloading in web applications?

Data preloading involves loading data before it's needed to improve performance. Key practices include using caching, lazy loading, and optimizing API calls.

Can you explain lazy loading and how it fits into data preloading?

Lazy loading is a technique where data is loaded only when it's needed, reducing initial load time and resource usage.

What are some common pitfalls to avoid when implementing data preloading?

Common pitfalls include overloading the initial load with too much data, not considering user experience, and failing to manage cache effectively.

How can I measure the effectiveness of my data preloading strategy?

You can measure effectiveness by tracking load times, user engagement metrics, and monitoring server performance before and after implementation.
