HTML - What is a Web API?

A Web API is a developer's dream. It can extend the functionality of the browser

It can provide easy syntax to complex code

A pplication P rogramming I nterface. An API is some kind of interface that includes a set of functions and subroutines that allow programmers to access specific features or data of an application, operating system or other services. A Web API is an application programming interface for the Web.

Here are some of the main HTML5 APIs:

1.

• This API is used to access the current location of a user (with latitude and longitude).

2.

3.

• This API

4.

• This API allows a JavaScript to run in the background, without affecting the performance of the page. Users can continue to do whatever they want: clicking, selecting things, etc., while the web worker runs in the background.

5.

• This API allows a web page to automatically get updates from a server.

6.

• This API lets you draw graphics, on the fly, via JavaScript.

When implementing an HTML API, you should always:

• Always check that the target browsers support the API. Always add script or message to be run if a browser does not support it.

• Add robust error handling to take care of scenarios where an API may not function as expected, to ensure a seamless user experience.

• When using an API that accesses sensitive data, like the Geolocation API (which will access the user's geographical position), always prompt the user for consent before proceeding.

Third party APIs are not built into your browser. To use these APIs, you will have to download the code from the Web.
