In web development, one of the most important part is to use REST api. When I start working on api with vanilla JS, I noticed small time difference between call and response. It's good practice to show end user something is happening after his interaction with website.
So here's the guide of showing loading animation on fetch api calls with vanilla JS.
Let's get started
Let's start with html.
We are displaying loading animation using
<div id="loading"></div>. This element is hidden by default. We are going to manipulate it, to show or hide it according our requirement.
loader.className = "display";this will add display class to
<div id="#loading"></div>, which turn
We are using
setTimeoutto hide loading animation after 5 second. Sometimes we may get late response, then timeout time should be increased.
displayLoading() called it will display loading animation and when
hideLoading() called it will hide loading animation setting
Now for remaining JS
This part is straight forward.
fetchHandler() to fetch data from api.
url I'm using is dummy url which only return 'Testing, you are' for any input.
Here's the pen.
