Angular5 SVG Round Progressbar

Ionic/Angular module that uses SVG to create a circular progressbar with Angular5 and AOT(Ahead of Time) compiler support. Originally made by crisbeto, crisbeto/angular-svg-round-progressbar. Go give that repo a star for his efforts!

Note

responsive and semicircle option is not available in this versio because of some issues. Will fix that later or you may contirubte to this repo.

NPM

https://www.npmjs.com/package/angular5-svg-round-progressbar

Installation

First you have to install the module through npm:

npm install angular5-svg-round-progressbar --save

Afterwards you need to import the RoundProgressModule in your module:

import {NgModule} from '@angular/core';
import {RoundProgressModule} from 'angular5-svg-round-progressbar';

@NgModule({
  imports: [RoundProgressModule]
})
export class YourModule {};

Options

Name	Description	Required	Default value	Possible values
current	The current progress. Limited by the max option.	Yes	undefined	number
max	The progress' maximum value.	Yes	undefined	number
radius	Radius of the circle.	No	125	number
color	The color of the current value on the circle.	No	#45ccce	string
background	Color of the circle's background.	No	#eaeaea	string
stroke	Specifies the circle's thickness.	No	15	number

rounded	Whether the current progress ending should be rounded or straight.	No	false	boolean
duration	The duration of the animation. Pass 0 for no animation.	No	800	number
animationDelay	Milliseconds to wait before starting an animation.	No	0	number
onRender	Callback function that gets executed every time the circle is animated. The function gets called with the current progress as it is being animated.	No	undefined	Function
animation	The easing function that will be used when animating.	No	easeOutCubic	linearEase easeInQuad easeOutQuad easeInOutQuad easeInCubic easeOutCubic easeInOutCubic easeInQuart easeOutQuart easeInOutQuart easeInQuint easeOutQuint easeInOutQuint easeInSine easeOutSine easeInOutSine easeInExpo easeOutExpo easeInOutExpo easeInCirc easeOutCirc easeInOutCirc easeInElastic easeOutElastic easeInOutElastic easeInBack easeOutBack easeInOutBack easeInBounce easeOutBounce easeInOutBounce

Minimal example:

Full example:

<round-progress
    [current]="current"
    [max]="max"
    [color]="'#45ccce'"
    [background]="'#eaeaea'"
    [radius]="125"
    [stroke]="20"
    [semicircle]="true"
    [rounded]="true"
    [clockwise]="false"
    [responsive]="false"
    [duration]="800"
    [animation]="'easeInOutQuart'"
    [animationDelay]="0"
    (onRender)="doSomethingWithCurrentValue($event)"></round-progress>

Configuring the default values

The module comes with some pre-configured options for things like colors, size, stroke etc. If these don't match your app's design, you can change the global defaults by using the RoundProgressConfig service. Whenever an option isn't defined on a round-progress element, it's value will be taken from the defaults.

import {NgModule} from '@angular/core';
import {RoundProgressModule, RoundProgressConfig} from 'angular5-svg-round-progressbar';

@NgModule({
  imports: [RoundProgressModule]
})
export class YourModule {
  constructor(private _config: RoundProgressConfig) {
    _config.setDefaults({
      color: '#f00',
      background: '#0f0'
    });
  }
};
