Migration guide

1.x.x to 2.0.0

Use a named import to import CircularProgressbar

Before:

import CircularProgressbar from 'react-circular-progressbar';

After:

import { CircularProgressbar } from 'react-circular-progressbar';

Use props.value instead of props.percentage

Before:

<CircularProgressbar percentage={66} />

After:

<CircularProgressbar value={66} />

Replace props.initialAnimation with a setTimeout value transition

This is only applicable if you're using props.initialAnimation, which is removed in v2.0.0. Instead, you must trigger the animation by changing value from one value to another yourself.

Before:

<CircularProgressbar percentage={66} initialAnimation />

After:

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. Then you can do:

<ProgressProvider valueStart={0} valueEnd={66}>
  {(value) => <CircularProgressbar value={value} />}
</ProgressProvider>

0.x.x to 1.0.0

The main breaking change is the replacement of the classForPercentage prop with className, and the textForPercentage prop with text [#61].

How to migrate:

Previously, the text would by default display as "{yourPercentage}%". With 1.0, if you want to display that text, you need to supply the text prop explicitly:

const percentage = 60;

<CircularProgressbar percentage={percentage} text={`${percentage}%`} />;

If you had customized either classForPercentage or textForPercentage functions before 1.0, you can reuse the same function for className and text. But instead of passing the function as a prop, you now need to pass the called function's value.

So if your pre-1.0 usage looked like this:

function customClassForPercentage(percentage) {
  if (percentage < 50) {
    return 'red';
  } else {
    return 'blue';
  }
}

function customTextForPercentage(percentage) {
  if (percentage === 100) {
    return `${percentage}!!!`;
  } else {
    return `${percentage}%`;
  }
}

const percentage = 60;

<CircularProgressbar
  percentage={percentage}
  classForPercentage={customClassForPercentage} // pass function
  textForPercentage={customTextForPercentage} // pass function
/>;

...you can make a small change to make it work in 1.0 by using the new props and calling the functions instead:

<CircularProgressbar
  percentage={percentage}
  className={customClassForPercentage(percentage)} // call function directly
  text={customTextForPercentage(percentage)} // call function directly
/>
