react-tiny-popover

What is react-tiny-popover?

The react-tiny-popover package is a lightweight and highly customizable popover component for React. It allows developers to create popovers that can be attached to any element, providing additional information or interactive content in a small overlay.

What are react-tiny-popover's main functionalities?

Basic Popover

This code demonstrates a basic usage of the react-tiny-popover package. It shows how to create a popover that toggles open and closed when a button is clicked.

import React from 'react';
import Popover from 'react-tiny-popover';

const App = () => {
  const [isPopoverOpen, setIsPopoverOpen] = React.useState(false);

  return (
    <div>
      <Popover
        isOpen={isPopoverOpen}
        position={['top', 'right', 'bottom', 'left']}
        content={<div>Popover Content</div>}
      >
        <button onClick={() => setIsPopoverOpen(!isPopoverOpen)}>Toggle Popover</button>
      </Popover>
    </div>
  );
};

export default App;

Custom Popover Content

This example shows how to use custom content within the popover. The content can be styled and structured as needed.

import React from 'react';
import Popover from 'react-tiny-popover';

const CustomContent = () => (
  <div style={{ padding: '10px', backgroundColor: '#f0f0f0', borderRadius: '5px' }}>
    <h3>Custom Content</h3>
    <p>This is a custom popover content.</p>
  </div>
);

const App = () => {
  const [isPopoverOpen, setIsPopoverOpen] = React.useState(false);

  return (
    <div>
      <Popover
        isOpen={isPopoverOpen}
        position={['top', 'right', 'bottom', 'left']}
        content={<CustomContent />}
      >
        <button onClick={() => setIsPopoverOpen(!isPopoverOpen)}>Toggle Popover</button>
      </Popover>
    </div>
  );
};

export default App;

Popover with Arrow

This code demonstrates how to add an arrow to the popover, making it clear which element the popover is associated with.

import React from 'react';
import Popover from 'react-tiny-popover';

const App = () => {
  const [isPopoverOpen, setIsPopoverOpen] = React.useState(false);

  return (
    <div>
      <Popover
        isOpen={isPopoverOpen}
        position={['top', 'right', 'bottom', 'left']}
        content={<div>Popover Content with Arrow</div>}
        padding={10}
        arrow={true}
      >
        <button onClick={() => setIsPopoverOpen(!isPopoverOpen)}>Toggle Popover</button>
      </Popover>
    </div>
  );
};

export default App;

Other packages similar to react-tiny-popover

react-popper

react-popper is a powerful library for positioning tooltips and popovers in React. It provides more advanced positioning capabilities and flexibility compared to react-tiny-popover, but it may require more configuration.

react-tooltip

react-tooltip is a simple and easy-to-use tooltip library for React. While it focuses primarily on tooltips, it can be used to create popovers as well. It is less customizable than react-tiny-popover but is very straightforward to use.

react-bootstrap

react-bootstrap is a popular library that provides Bootstrap components for React, including popovers. It offers a wide range of pre-styled components and is ideal for projects already using Bootstrap. It is heavier than react-tiny-popover but integrates well with the Bootstrap framework.

README

react-tiny-popover

A lightweight, highly customizable, and non-intrusive popover react HOC with no other dependencies! Typescript friendly, as well!

The component renders its child directly, without wrapping it with anything on the DOM, and in addition renders solely the JSX you provide when shown. It simply grabs the child component's coordinates and provides a robust and non-intrusive way for you to position your own content around the child. Your content will be appended to document.body when shown, and removed when hidden. You can use it to generate little popups around input or button elements, menu fly-outs, or in pretty much any situation where you want some content to appear and disappear dynamically around a target. You can also specify your own location for your popover content or hook into the existing positioning process, allowing you to essentially make modal windows and the like, as well!

react-tiny-popover will also guard against your window's current dimensions and reposition itself to prevent any kind of hidden overflow. You can specify a priority of desired positions to fall back to, if you'd like.

Optionally, you can provide a renderer function for your popover content that injects the popover's current position, in case your content needs to know where it sits in relation to its target.

Since react-tiny-popover tries to be as non-invasive as possible, it will simply render the content you provide with the position and padding from the target that you provide. If you'd like an arrow pointing to the target to appear along with your content and don't feel like building it yourself, you may be interested in wrapping your content with the customizable ArrowContainer component, also provided! ArrowContainer's arrow will follow its target dynamically, and handles boundary collisions as well.

API

Popover

Property	Type	Required	Description
children	JSX.Element	✔️	This is the JSX.Element target that you'd like the popover content to track. Sweet.
isOpen	boolean	✔️	When this boolean is set to true, the popover is visible and tracks the target. When the boolean is false, the popover content is neither visible nor present on the DOM.
content	JSX.Element or Function	✔️	Here, you'll provide the content that will appear as the popover. Rather than a JSX element like a <div>, you may supply a function that returns a JSX.Element, which will look like this: ({ position, targetRect, popoverRect, align, nudgedLeft, nudgedTop }) => JSX.Element. Here, position is of type 'top', 'bottom', 'left', 'right'. align is of type start, center, or end. Both targetRect and popoverRect are ClientRect objects of format { height: number, width: number, top: number, left: number, right: number, bottom: number }, and represent the popover content and target div's coordinates within your browser's window. nudgedLeft and nudgedTop specify the X and Y offset the popover content is shifted by to keep it within the window's bounds during a boundary collision. You may want to use these values to adjust your content depending on its location in relation to the window and the target, especially if you have repositioning disabled. Sweet.
padding	number		This number determines the gap, in pixels, between your target content and your popover content. Defaults to 6.
windowBorderPadding	number		This number specifies the padding around the browser window's border that boundary violations are determined at. Defaults to 6.
position	string or string[]		You may provide a preferred position for your popover content in relation to its target. Valid values are 'top', 'bottom', 'left', 'right'. The default is 'top'. If you'd like, you can supply an array of preferred positions ranked in priority order. If the popover reaches the edge of the window, it will attempt to render in the order you specify. The default order is ['top', 'right', 'left', 'bottom']. If you'd like, you can provide a shorter array like ['top', 'left']. The remaining positions will be automatically filled in. If you provide any duplicate or other values in the array, they will be ignored.
contentLocation	object or Function		If you'd like to hook directly into the positioning process, you may do so here! You can provide an object of type { top: number, left: number } to completely override the popover content's (popoverRect) location. You can also provide a function that looks like this: ({ targetRect, popoverRect, position, align, nudgedLeft, nudgedTop }) => { top: number, left: number } (The arguments to this function are the same as the content renderer function above). Note that if repositioning is enabled, it happens before this step, so within here you'll be responsible for keeping popoverRect within the window's bounds if that matters to you!
align	string		Possible values are start, center, and end. If start is specified, the popover content's top or left location is aligned with its target's. With end specified, the content's bottom or right location is aligned with its target's. If center is specified, the popover content and target's centers are aligned. Defaults to center.
onClickOutside	Function		If react-tiny-popover detects a click event outside of the target and outside of the popover, you may handle this event here, in the form of (e: MouseEvent) => void.
disableReposition	boolean		If this property is enabled, rather than the popover content repositioning on a boundary collision, the popover content container will move beyond the window's bounds. You are, however, supplied with nudgedLeft and nudgedTop values, so you may choose to handle content overflow as you wish.
transitionDuration	number		The length of the popover content's fade transition in seconds. Defaults to 0.35.
containerStyle	object (CSSStyleDeclaration)		Your popover content is rendered to the DOM in a single container div. If you'd like to apply style directly to this container div, you may do so here! Be aware that as this div is a DOM element and not a React element, all style values must be strings. For example, 5 pixels must be represented as '5px', as you'd do with vanilla DOM manipulation in Javascript.
containerClassName	string		If you'd like to apply styles to the single container div that your popover content is rendered within via stylesheets, you can specify a custom className for the container here.

ArrowContainer

Property	Type	Required	Description
position	string	✔️	The ArrowContainer needs to know its own position in relation to the target, so it can point in the correct direction!
children	JSX.Element	✔️	You'll provide the ArrowContainer with a JSX.Element child to render as your popover content.
targetRect	object	✔️	The ArrowContainer must know its target's bounding rect in order to position its arrow properly. This object is of type { width: number, height: number, top: number, left: number, right: number, bottom: number }.
popoverRect	object	✔️	This allows the ArrowContainer to know its own bounding rect in order to position its arrow properly. This object is of type { width: number, height: number, top: number, left: number, right: number, bottom: number }.
arrowSize	number		The size of the triangle arrow. Defaults to 10 or something like that.
arrowColor	string		The color of the arrow! Exciting.
arrowStyle	object		You may append to the arrow's style here.
style	object		If you'd like to append to the style of the ArrowContainer itself, do so here. Rad.
