# React Circular Progressbar [![npm version](https://badge.fury.io/js/react-circular-progressbar.svg)](https://www.npmjs.com/package/react-circular-progressbar) [![Bundle size](https://img.shields.io/bundlephobia/min/react-circular-progressbar.svg)](https://bundlephobia.com/result?p=react-circular-progressbar) A circular progressbar component, built with SVG and extensively customizable. [**Try it out on CodeSandbox**](https://codesandbox.io/s/vymm4oln6y).

## Version 2.0.0 is out! 👋 **New features:** - Use `import { CircularProgressbarWithChildren }` in order to [put arbitrary JSX inside the component](/README.md#adding-arbitrary-text-or-content-inside-the-progressbar). - Use `import { buildStyles }` to make it easier to [customize styles](/README.md#using-the-styles-prop). - Use `props.minValue` and `props.maxValue` to specify a range other than 0-100. **Breaking changes:** if you're upgrading from an older version, take a look at [UPGRADING.md](/UPGRADING.md) for instructions on how to migrate. Documentation for v1.x.x will still be available at [README_v1.md](/README_v1.md). ## Installation Install with yarn: ```bash yarn add react-circular-progressbar ``` or npm: ```bash npm install --save react-circular-progressbar ``` ## Usage Import the component and default styles: ```javascript import { CircularProgressbar } from 'react-circular-progressbar'; import 'react-circular-progressbar/dist/styles.css'; ``` **Note**: Importing CSS requires a CSS loader (if you're using create-react-app, this is already set up for you). If you don't have a CSS loader, you can copy [styles.css](src/styles.css) into your project instead. Now you can use the component: ```jsx const percentage = 66; ; ``` If your values are not in percentages, you can adjust `minValue` and `maxValue` to select the scale you want: ```jsx const value = 0.66; ; ``` The progressbar is designed to fill the width of its container. You can size the progressbar by sizing its container: ```jsx

``` This makes the progressbar work well with responsive designs and grid systems. ## Props [**Take a look at the CodeSandbox**](https://codesandbox.io/s/vymm4oln6y) for interactive examples on how to use these props. ℹ️ Version 1.0.0 removed the `classForPercentage` and `textForPercentage` props in favor of `className` and `text` props. Version 2.0.0 replaces `percentage` with `value` and removes the `initialAnimation` prop. Take a look at [UPGRADING.md](/UPGRADING.md) for instructions on how to migrate. | Name | Description | | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `value` | Completion value of the progressbar, from `minValue` to `maxValue`. Required. | | `minValue` | Minimum value of the progressbar. Default: `0`. | | `maxValue` | Maximum value of the progressbar. Default: `100`. | | `className` | Classes to apply to the svg element. Default: `''`. | | `text` | Text to display inside progressbar. Default: `''`. | | `strokeWidth` | Width of circular line relative to total width of component, a value from 0-100. Default: `8`. | | `background` | Whether to display background color. Default: `false`. | | `backgroundPadding` | Padding between background circle and path/trail relative to total width of component. Only used if `background` is `true`. Default: `0`. | | `counterClockwise` | Whether to rotate progressbar in counterclockwise direction. Default: `false`. | | `circleRatio` | Number from 0-1 representing ratio of the full circle diameter the progressbar should use. Default: `1`. | | `classes` | Object allowing overrides of classNames of each svg subcomponent (root, trail, path, text, background). Enables styling with react-jss. See [this PR](https://github.com/kevinsqi/react-circular-progressbar/pull/25) for more detail. | | `styles` | Object allowing customization of styles of each svg subcomponent (root, trail, path, text, background). | ## Theming (customizing styles) Use CSS or inline styles to customize the styling - the default CSS is a good starting point, but you can override it as needed. #### Using the `styles` prop You can use the `styles` prop to customize each part of the progressbar (the root svg, path, trail, text, and background). This uses the native `style` prop for each subcomponent, so you can use any CSS properties here, not just the ones mentioned below. As a convenience, you can use `buildStyles` to configure the most common style changes: ```jsx import { CircularProgressbar, buildStyles } from 'react-circular-progressbar'; const percentage = 66; ; ``` `buildStyles` is a shorthand, but you can also build the `styles` object yourself. It's an object with `root`, `path`, `trail`, `text`, and `background` properties, which are each a set of inline styles to apply to the relevant SVG subcomponent. Here's the equivalent set of styles as above, without using `buildStyles`: ```jsx ``` However, you're not limited to the CSS properties shown above—you have the full set of SVG CSS properties available to you when you use `prop.styles`. See the [CodeSandbox examples](https://codesandbox.io/s/vymm4oln6y) for a live example on how to customize styles. #### Using CSS You can also customize styles with CSS. There are equivalent CSS hooks for the root, path, trail, text, and background of the progressbar. If you're importing the default styles, you can override the defaults like this: ```jsx import 'react-circular-progressbar/dist/styles.css'; import './custom.css'; ``` ```css // custom.css .CircularProgressbar-path { stroke: red; } .CircularProgressbar-trail { stroke: gray; } .CircularProgressbar-text { fill: yellow; } .CircularProgressbar-background { fill: green; } ``` ## Adding arbitrary text or content inside the progressbar If you want to add multiple lines of text or images within the progressbar, you can overlay it on top of a regular `` using absolute positioning. `react-circular-progressbar` ships with a `CircularProgressbarWithChildren` component which makes it easy to do that by using JSX children: ```jsx import { CircularProgressbarWithChildren } from 'react-circular-progressbar'; {/* Put any JSX content in here that you'd like. It'll be vertically and horizonally centered. */} doge

; ```

`CircularProgressbarWithChildren` has all the same props as `CircularProgressbar` - you can use it the exact same way otherwise. ## Animating text If you want to animate the text as well as the path, you'll need to transition the `value` prop from one value to another using a third-party animation library like `react-move` and an easing library like `d3-ease`. You can use a render prop wrapper like **[AnimatedProgressProvider.js inside this Codesandbox](https://codesandbox.io/s/vymm4oln6y)** to help manage the transitioning value, and use it like this: ```jsx import { easeQuadInOut } from 'd3-ease'; {(value) => { const roundedValue = Math.round(value); return ( ); }} ; ``` ## Animating progressbar upon component mount or upon visible **Upon component mount** In order to trigger the default CSS animation on mount, you'll need to change `props.value` from 0 to your desired value with a `setTimeout` in `componentDidMount`. You can use a wrapper component to help manage this like [ProgressProvider.js in this Codesandbox](https://codesandbox.io/s/0zk372m7l). Then you can do: ```jsx {(value) => } ``` **Upon visible** To animate the progressbar only when it becomes visible (e.g. if it's below the fold), you can use something like `react-visibility-sensor` which detects whether the component is visible or not. [Here's a Codesandbox example](https://codesandbox.io/s/81wzmm8n00). ## Fixing text centering in Internet Explorer (IE) Because the `dominant-baseline` CSS property does not work in IE, the text may not be centered in IE. The **recommended way to fix this** is to instead of using `props.text`, use `CircularProgressbarWithChildren` and put your text in `props.children`, [as described here](/README.md#adding-arbitrary-text-or-content-inside-the-progressbar). However, you can also work around this by setting the `text` prop to be a `` element and then adjusting the `dy` vertical offset, like so: ```jsx // Use feature or browser detection to determine if IE const needDominantBaselineFix = ... {percentage}} /> ``` [See this Codesandbox example](https://codesandbox.io/s/x8o1zx7j4) to see this in action. ## Advanced usage - [Applying a gradient to the progressbar](https://github.com/kevinsqi/react-circular-progressbar/issues/31#issuecomment-338216925) - [Creating a dashboard/speedometer style progressbar](https://github.com/kevinsqi/react-circular-progressbar/issues/49) ## Supported platforms react-circular-progressbar does not work with React Native, because React Native does not support `
