react-countup

What is react-countup?

The react-countup package is a React component that allows you to create animated number counters. It is useful for displaying statistics, financial data, or any other numerical information that benefits from a dynamic presentation.

What are react-countup's main functionalities?

Basic Count Up

This feature allows you to create a simple count-up animation from 0 to a specified number. In this example, the counter will animate from 0 to 100.

<CountUp end={100} />

Custom Start and End Values

You can specify both the start and end values for the count-up animation. Here, the counter will animate from 50 to 150.

<CountUp start={50} end={150} />

Duration

This feature allows you to set the duration of the count-up animation. In this example, the counter will animate from 0 to 100 over a period of 5 seconds.

<CountUp end={100} duration={5} />

Formatting Numbers

You can format the numbers with separators for better readability. In this example, the counter will animate to 1,000 with a comma as the thousands separator.

<CountUp end={1000} separator=',' />

OnComplete Callback

This feature allows you to execute a callback function once the count-up animation is complete. Here, a message 'Completed!' will be logged to the console when the counter reaches 100.

<CountUp end={100} onEnd={() => console.log('Completed!')} />
