How to Integrate yrWeather into Your Weather App

Overview

This guide shows a clear, step-by-step approach to integrating yrWeather into a weather app. It covers authentication, requesting forecasts, parsing responses, caching, error handling, and example code for common platforms. Assumed stack: REST API access to yrWeather JSON endpoints; adapt as needed.

1. Plan your integration

Data needed: current conditions, hourly forecast, daily forecast, alerts, locations.
Update frequency: current conditions every 5–15 minutes; hourly forecasts every 30–60 minutes; daily once per hour.
Rate limits & quotas: assume limits—use caching and backoff.
User experience: decide on offline behavior, error messages, and permission prompts for location.

2. Authentication & endpoints

API key: obtain a key if required by yrWeather.
Endpoints: typical endpoints you’ll use:
- GET /v1/current?lat={lat}&lon={lon}
- GET /v1/hourly?lat={lat}&lon={lon}&hours={n}
- GET /v1/daily?lat={lat}&lon={lon}&days={n}
- GET /v1/alerts?lat={lat}&lon={lon}

(Adjust paths per yrWeather’s docs.)

3. Requesting data

HTTP client: use stable libraries (fetch, axios, NSURLSession, OkHttp).
Example REST call (pseudocode):

Code
GET https://api.yrweather.example/v1/hourly?lat=59.91&lon=10.75&hours=48
Headers: Authorization: Bearer YOUR_API_KEY

Query params: units (metric/imperial), language, timezone.

4. Parsing responses

Map JSON fields to your app models: timestamp, temp, feels_like, wind_speed, wind_dir, precipitation, icon_code, description.
Convert timestamps to user’s timezone; normalize units.

Example model (fields):

time (ISO8601)
temp_c
wind_kph
precip_mm
icon_code
summary

5. Caching & rate limiting

Short-term cache: store current/hourly responses for 5–15 minutes.
Long-term cache: daily forecasts for 30–60 minutes.
ETag/If-None-Match: use conditional requests to reduce bandwidth.
Backoff: exponential backoff on 429/5xx responses.

6. Error handling & fallbacks

Show cached data if network fails.
Display friendly messages for permission denied, offline, or API errors.
Implement retry with jitter for transient errors.
Monitor API error rates and log analytics.

7. Icons & visualization

Use yrWeather icon set if provided; otherwise map icon_code to your assets.
Animate transitions between states (sunny→cloudy→rain).
Show precipitation probability bars for hourly view and confidence ranges for daily highs/lows.

8. Location management

Use device geolocation with permission prompts.
Provide manual search by city/ZIP coordinates.
Reverse geocode coordinates to display place names.

9. Notifications & alerts

Subscribe to alerts endpoint and schedule local push notifications for severe weather.
Throttle notifications to avoid spamming.

10. Testing & monitoring

Test across timezones and DST transitions.
Validate parsing with mocked API responses: empty fields, nulls, new enum values.
Monitor latency, error rates, and API usage.

11. Example implementations

Web (JavaScript): fetch + cache in IndexedDB/localStorage; render with React.
iOS (Swift): URLSession, Codable models, background fetch for updates.
Android (Kotlin): Retrofit + Coroutine + Room for caching.

12. Quick checklist before release

API key securely stored (not in source).
Caching & backoff implemented.
Graceful offline mode.
Unit tests for parsing and timezone handling.
Accessibility for color/contrast in icons.

If you want, I can generate sample request/response JSON and a complete code example for one platform (specify: JavaScript, Swift, or Kotlin).
