This course is a practical guide on using the OpenWeatherMap APIs to retrieve current and forecast weather data for a specific location. 

In this course, you’ll learn how to get weather forecasts for five days, with data after every 3-hour interval. You’ll learn to get the current, forecast, and historical air pollution data for a specific location. This course also introduces the Geocoding API, a simple tool to get geographical coordinates using the location’s name. Also, you’ll integrate the OpenWeatherMap APIs into a functional web application using the React framework and Express backend. Lastly, this course provides recommendations and resources to explore the OpenWeatherMap APIs further.

This course holds relevance in various web applications that utilize weather API to display weather data on their dashboards and machine learning applications that rely on weather data. The Geocoding API is highly valuable in developing location-aware applications, a trend that is currently very popular.

Integrate the OpenWeatherMap APIs in JavaScript

Weather forecasts provide useful information to determine any forthcoming climate changes. They enable people and businesses to guard against any unfavorable circumstances that may arise due to various weather conditions. They also allow them to plan their activities and make informed decisions considering the impacts of the forthcoming weather.

## What are the OpenWeatherMap APIs?

The [OpenWeatherMap APIs](https://openweathermap.org/api) allow us to get weather data for any given location. This data comes with a wide range of meteorological parameters that extend from the historical weather data from the past forty years to the current weather, minutely forecasts over the next two hours, and hourly forecasts over the next week. The OpenWeatherMap APIs come with a variety of subscription packages that provide a number of services and features to match a variety of user requirements.

The weather products are based on open-source data and technologies. These APIs provide access to large amounts of weather data generated from fundamental global forecast models based on convolutional neural networks and various machine learning technologies. Next, these APIs are enhanced with radar-based nowcasts, weather satellite data, a wide network of weather stations, rain gauges, and other weather sensors.

## What is an API?

An **API** is a software gateway that allows different software components to communicate with each other. APIs help expose the capabilities of an application to the outer world, allowing for programmatic access to their data.

Consider the case of an application service like OpenWeatherMap that provides weather data and forecasts. Building and exposing an API for this service will allow others to programmatically fetch the data this service offers, such as the weather forecasts for a given location.

We can provide examples of other popular services that provide APIs for extended use cases. Widely used services such as YouTube, Reddit, Google Maps, and others provide APIs that allow authorized clients to access the resources provided by these systems.

This course is designed for developers interested in developing weather applications. The OpenWeatherMap APIs enable the development of high-quality weather applications that can be delivered to the market quickly.

This course is also meant for users interested in integrating weather APIs into their existing applications. This course will provide an understanding of the various APIs that OpenWeatherMap offers with hands-on examples.

To take this course, a basic understanding of the following is required:

* APIs
* JavaScript programming language
* React, a JavaScript-based free and open-source frontend library
* Express.js, a Node.js backend web application framework for building RESTful APIs
* HTTP request and response formats

By the end of the course, we'll be able to:

* Understand the different endpoints of the OpenWeatherMap APIs, their usage, and their structures.
* Generate current weather data and forecasts for locations of our choice.
* Generate current, forecast, and historical air pollution data for locations of our choice.
* Explore a simple weather application developed in React with a backend server developed in Express.js, integrated with the OpenWeatherMap APIs.

Weather forecasts provide useful information to determine any forthcoming climate changes. They enable people and businesses to guard against any unfavorable circumstances that may arise due to various weather conditions. They also allow them to plan their activities and make informed decisions considering the impacts of the forthcoming weather.
