Table of Contents

Introduction

SProgress is a simple on-scroll progress bar developed for web apps. It aims to give a user feedback as to how far they are in an article. Inspired by Alligator.io. A brief usage can be seen below 👇🏻

SProgress Usage

Installation

Npm or Bower

To install the package via npm, simply run the command below

$ npm install sprogress --save
$ yarn add sprogress -S

Via CDN links

You can also make use of the cdn links if you dont want to install the package. Add the following to your html file

<script src="https://unpkg.com/sprogress@1.0.2/lib/sprogress.min.js"></script>

Usage

After installing the package, you can simply make use of it by call the init function provided.

import SProgress from 'sprogress';

SProgress.init({});

The init function takes in an object which is used to customize the SProgress bar. More on that below

N.B - If you are using the CDN, you don't need to call the init method simply add the script tag and you all set 😁

Events

SProgress also triggers the scrollDistanceEvent event when the specified scrollDistanceTarget is reached by the progress bar. This can be useful if you want to display a feature to the user(maybe a newsletter modal) when they are half way into the page/article.

Event - scrollDistanceEvent

Implementation

import SProgress from 'sprogress';

SProgress.init({
	scrollDistanceTarget: 60,
});

document.addEventListener('scrollDistanceEvent', displayNewsLetterModal, {
	once: true,
});

N.B - The once object passed to the addEventListener in other to invoke the handler only once. Highly recommended if you don't want the handler trigger more than once. Have a look here to learn more

Options

The following are the options that SProgress supports:-

color

String

This basically customizes the color of the progress bar.

height

Integer

This can be used to manipulates the height of the progress bar.

scrollDistanceTarget

Integer

This is used to specify a certain distance for the scrollDistanceEvent to fire.

Customization

With SProgress, the following properties can be customized:-

Color

String

  import SProgress from 'sprogress';

  SProgress.init({
    color: // Your color here in hex |rgb |rgba format
  });

Height

Integer

import SProgress from 'sprogress';

SProgress.init({
	height: 10,
});

Using Classname

The default classname for the progress bar is scroll-progress and with that you can create you very own css file and manipulate the class to best suit your needs.

.scroll-progress {
	/* CSS styles here */
}
