A simple and responsive Pokédex built with HTML5, CSS3, and JavaScript that demonstrates efficient data fetching with batch requests, lazy loading, and local caching.
This project fetches Pokémon data from the PokéAPI and displays it in a clean, minimal interface. It uses performance techniques like batch requests and lazy loading to handle a large dataset smoothly, while caching data in localStorage for faster subsequent loads.
During the development of this Pokédex, I deepened my understanding of key frontend performance techniques, such as:
-
Batch requests: Grouping multiple API calls together to avoid server overload and efficiently control data flow.
-
Lazy loading: Loading data and UI elements progressively, fetching only what’s necessary initially and deferring the rest to optimize initial load times.
-
Local caching (localStorage): Storing data in the browser to speed up future accesses, reducing the number of API calls and improving the overall app responsiveness.
These practices are essential when working with large datasets and help deliver a faster, smoother user experience.
