Popover JS

A lightweight JavaScript/TypeScript library for creating and managing popovers in web applications built on top the Popover API standard. Compatible with React and uses Popper.js for positioning.

Features

Easy integration with any JS/TS project
Supports positioning popovers at the top, bottom, left, or right of the target element
Supports customizing the appearance of the popover with inline CSS
Simple API for showing, hiding, and toggling popovers
React component for seamless React integration
Content can be HTML, or plain text

Demo

Availabe Props

target - The target element for the popover
content - The content of the popover
position - The position of the popover relative to the target element (optional default to bottom)
offset - The offset of the popover from the target element (optional)
style - The style of the popover (optional)

Installation

Install the package via npm:

npm install react-popoverjs

Usage

Declarative Approach

You can create popovers using HTML attributes:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Popover Example</title>
</head>
<body>
  <button popovertarget="mypopover">Toggle the popover</button>
  <div id="mypopover" popover>Popover content</div>

  <script src="popover.js"></script>
</body>
</html>

Programmatic Approach

Basic Example

Import the Popover class and create a new popover instance:

import { Popover } from 'react-popoverjs';

const button = document.querySelector('#myButton');
const popover = new Popover({
  target: button,
  content: 'Hello, Popover!',
  position: 'bottom', // Default position
  offset: [0, 16], // Default offset of 16px
  style: {
    backgroundColor: 'lightblue',
    color: 'black',
  },
});

// Manually control the popover
popover.show();
popover.hide();
popover.toggle();

React Integration

Use the PopoverComponent for integrating popovers within React applications.

Example

App.tsx:

import React, { useRef, useEffect, useState } from 'react';
import { PopoverComponent } from 'react-popoverjs';

const App: React.FC = () => {
  const buttonRef = useRef<HTMLButtonElement>(null);
  const [target, setTarget] = useState<HTMLElement | null>(null);
  const content: string = `
    <div>
      Welcome to react-popoverjs!<br />
      Use this library to create popovers in your React applications.<br />
      You can customize the content, position, and style of the popovers.<br />
      It utilizes the standard <a target="_blank" href="https://developer.mozilla.org/en-US/docs/Web/API/Popover_API">browser Popover API</a>, and Popper.js for positioning, ensuring it is lightweight and fast.
    </div>
  `;

  useEffect(() => {
    if (buttonRef.current) {
      setTarget(buttonRef.current);
    } else {
      console.log('Button ref is not attached yet.');
    }
  }, []);

  return (
    <div style={styles.container}>
      <button ref={buttonRef} style={styles.button}>Toggle Popover</button>
      {target && (
        <PopoverComponent 
          target={target} content={content} position='bottom'
          style={styles.popover}>
          <></> {/* Empty fragment as children */}
        </PopoverComponent>
      )}
    </div>
  );
};

const styles = {
  container: {
    display: 'flex',
    justifyContent: 'center',
    alignItems: 'center',
    height: '100vh',
    padding: '10px',
    boxSizing: 'border-box' as 'border-box',
  },
  button: {
    padding: '10px 20px',
    fontSize: '16px',
  },
  popover: {
    backgroundColor: 'white',
    color: 'black',
    border: '1px solid black',
  },
  '@media (max-width: 600px)': {
    container: {
      flexDirection: 'column' as 'column',
      height: 'auto',
    },
    button: {
      width: '100%',
      marginBottom: '10px',
    },
    popover: {
      marginLeft: '0',
      marginTop: '10px',
    },
  },
};

export default App;
