Weather App

Part of the Frontend Developer Roadmap.

Summary

A city-search weather app consuming a real external API — practice for `fetch`, async/await, loading/error states and rendering API data. The project also teaches real-world API integration patterns, including query parameters, asynchronous state, unreliable networks, rate limits, and user-friendly errors.

How to Learn This

  • 1Handle loading, error and empty states explicitly, not just the happy path. Validate your understanding by applying it in a small practical example.
  • 2Debounce the search input so you don't spam the API on every keystroke. Validate your understanding by applying it in a small practical example.
  • 3Cache recent searches in localStorage to avoid redundant API calls.
