React Dennis Progressbar

A simple and reusable Progressbar

Installation

The package can be installed via npm:

npm install react-dennis-progressbar --save

Or via yarn:

yarn add react-dennis-progressbar

You’ll need to install React separately since this dependency isn’t included in the package. Below is a simple example of how to use the Progressbar within React.

import React from 'react';
import ProgressBar from 'react-dennis-progressbar';


class Example extends React.Component {
  state = {
     stepNumber: 6,
  };

  changeStep = e => {
    e.preventDefault();
    this.setState((state) => 
    { 
      return {
        stepNumber: state.stepNumber + 1
      }
    })
  };

  render() {
    return (
      <div>
        <ProgressBar
            stepNumber={this.state.stepNumber}
            steps={[2,6,4,1,5]}
            bullets={true}
        />
        <button onClick={this.changeStep}>Click me</button>
      </div>
    );
  }
}

Configuration & Examples

The most basic use of the ProgressBar can be described with:

<ProgressBar stepNumber={6} steps={[2,6,4,1,5]}/>

The main formula to calculate and display percentage is:

let calculatedPercentage = Math.round(100 * this.state.stepNumber / [2,6,4,1,5].reduce((a,b) => a+b));

You can use bullets to visualize steps and substeps. It will split Progressbar into substeps. The number of bullets will be the length of your steps array + 1.

<ProgressBar
  stepNumber={6}
  steps={[2,6,4,1,5]}
  bullets={true}
/>

You also have possibility to add custom styles to Progressbar:

<ProgressBar
  stepNumber={6}
  steps={[2,6,4,1,5]}
  bullets={true}
  bulletColor={{
    active: '#ffc438',
    inactive: '#929292'
  }}
  lineColor={{
    active: '#1c2393',
    inactive: 'rgb(232, 9, 50)'
  }}
  lineHeight={5}
/>

How it works

The main point is your steps array. For example: we have the following steps array: [2,6,4,1,5]. If you want to use it without bullets: depends of your step it will calculate and fill the percentage of how many steps left, automatically. Just pass step. If you want to use Progressbar with bullets: the logic completely the same but with additional points. That each item of steps array will be a bullet, and each value of this item will be a number of substeps.

Props Description

Props	Type	Meaning
stepNumber	Number	Number of your current step
steps	Array	Array with steps and substeps. Element is the step itself, and its value is the number of substeps. For example: [3] means that in your steps array you'll have only one step which consists of 3 substeps.
bullets	Bool	To visualize and split steps and substeps.
bulletColor	Object	Option to style filled and unfilled bullets. Object which accepts two keys: active and inactive. To style both of them, just pass the color into their value.
lineColor	Object	Object
lineHeight	Number	This value will be applied as height of your Progressbar

Compatibility

React

We're always trying to stay compatible with the latest version of React. We can't support all older versions of React.

Latest compatible versions:

• React 16 or newer
• React 15.5
• React 15.4.1

Browser Support

The Progressbar is compatible with the latest versions of Chrome, Firefox, and IE10+.

Local Development

The master branch contains the latest version of the Progressbar component.

To begin local development:

1. npm install
2. npm start
3. npm run build

The last step starts documentation app as a simple webserver on http://localhost:3000.

You can run npm run test to execute the test suite and snapshots.
