Build Your Own Weather API

Project Description

The "Weather API" project aims to develop a comprehensive API that provides weather forecasts, weather alerts, and supports user preferences for units of measurement. This API will allow users to check the weather for their location, receive timely alerts about severe weather conditions, and customize their experience by setting preferred units (e.g., Celsius or Fahrenheit).

Detailed Description

Weather information is essential for planning daily activities, travel, and ensuring safety during severe weather conditions. This project will create an API that offers accurate and up-to-date weather data, helping users stay informed and prepared. Here’s a detailed look at how users will interact with the app:

  1. User Registration and Authentication:

    • Sign Up: New users can create an account by providing a username, email, and password. A confirmation email will be sent to verify the account.

    • Login: Registered users can log in using their email and password. Multi-factor authentication (MFA) will be supported for added security.

  2. Location Management:

    • Set Location: Users can set their current location manually or allow the app to detect it automatically using GPS.

    • Save Multiple Locations: Users can save multiple locations to quickly check the weather in different areas (e.g., home, work, travel destinations).

  3. Weather Forecasts:

    • Current Weather: Users can check the current weather conditions for their selected location, including temperature, humidity, wind speed, and precipitation.

    • Daily Forecast: Users can view the weather forecast for the next seven days, with detailed information for each day.

    • Hourly Forecast: Users can see the weather forecast for the next 24 hours, with updates every hour.

  4. Weather Alerts:

    • Severe Weather Alerts: Users will receive alerts about severe weather conditions such as storms, floods, and heatwaves. These alerts will include details about the nature of the threat and recommended actions.

    • Custom Alerts: Users can set custom alerts for specific weather conditions, such as temperature drops or high wind speeds.

  5. Preferences and Settings:

    • Units of Measurement: Users can choose their preferred units for temperature (Celsius or Fahrenheit), wind speed (mph or km/h), and other measurements.

    • Notification Settings: Users can customize their notification preferences, choosing how and when they want to receive weather alerts (e.g., email, SMS, push notifications).

Real-World Example

Consider Sarah, who relies on accurate weather information to plan her daily commute and outdoor activities. Sarah signs up for an account using her email and sets her home and work locations. She prefers to see the temperature in Celsius and wind speed in km/h.

Each morning, Sarah checks the current weather and the daily forecast to decide whether to take an umbrella or wear a jacket. She also receives real-time alerts on her phone about any severe weather conditions, such as thunderstorms or high winds, ensuring she can take necessary precautions.

When planning a weekend trip, Sarah saves her travel destination as an additional location. She checks the weather forecast there to pack appropriately and stay informed about any weather-related risks.

1. Introduction

The "Weather API" project aims to develop a comprehensive API that provides accurate weather forecasts, weather alerts, and supports user preferences for units of measurement. Users will be able to check the weather for their location, receive alerts about severe weather, and customize their experience.

2. Objectives

  • Allow users to sign up, log in, and manage their accounts.

  • Enable users to set and manage their locations.

  • Provide current weather conditions, daily and hourly forecasts.

  • Send real-time weather alerts to users.

  • Support user preferences for units of measurement and notification settings.

3. Functional Requirements

User Management

  • Sign Up: Users can create an account by providing a username, email, and password.

  • Login: Users can log in using their email and password.

  • Profile Management: Users can update their profile information and preferences.

Location Management

  • Set Location: Users can manually set or automatically detect their location.

  • Save Multiple Locations: Users can save multiple locations for quick access.

Weather Information

  • Current Weather: Users can view the current weather conditions.

  • Daily Forecast: Users can view the weather forecast for the next seven days.

  • Hourly Forecast: Users can view the weather forecast for the next 24 hours.

Weather Alerts

  • Severe Weather Alerts: Users receive alerts about severe weather conditions.

  • Custom Alerts: Users can set custom alerts for specific weather conditions.

Preferences and Settings

  • Units of Measurement: Users can set their preferred units for temperature, wind speed, etc.

  • Notification Settings: Users can customize their notification preferences.

4. Non-Functional Requirements

  • Scalability: The API should handle a growing number of users and locations.

  • Performance: The API should have a fast response time and handle concurrent requests efficiently.

  • Security: Implement authentication and authorization mechanisms to protect user data.

  • Reliability: The API should be highly available and handle failures gracefully.

  • Usability: The API should be easy to use and well-documented.

5. Use Cases

  • User Sign Up and Login: New users sign up and existing users log in.

  • Set and Manage Locations: Users set and manage their preferred locations.

  • Check Weather Information: Users check current weather, daily, and hourly forecasts.

  • Receive Weather Alerts: Users receive alerts for severe weather conditions.

  • Customize Preferences: Users set their preferred units of measurement and notification settings.

6. User Stories

  1. As a user, I want to sign up for an account so that I can save my preferred locations.

  2. As a user, I want to log in to my account so that I can access my weather information.

  3. As a user, I want to set my location so that I can check the weather for where I am.

  4. As a user, I want to save multiple locations so that I can quickly check the weather for different places.
