Example

Usage

npm install react-popper-tooltip

or

yarn add react-popper-tooltip

import React from 'react';
import {render} from 'react-dom';
import TooltipTrigger from 'react-popper-tooltip';

const Tooltip = ({
  getTooltipProps,
  getArrowProps,
  tooltipRef,
  arrowRef,
  placement
}) => (
  <div
    {...getTooltipProps({
      ref: tooltipRef,
      className: 'tooltip-container'
      /* your props here */
    })}
  >
    <div
      {...getArrowProps({
        ref: arrowRef,
        'data-placement': placement,
        className: 'tooltip-arrow'
        /* your props here */
      })}
    />
    Hello, World!
  </div>
);

const Trigger = ({getTriggerProps, triggerRef}) => (
  <span
    {...getTriggerProps({
      ref: triggerRef,
      className: 'trigger'
      /* your props here */
    })}
  >
    Click Me!
  </span>
);

render(
  <TooltipTrigger
    placement="right"
    trigger="click"
    tooltip={Tooltip}
  >
    {Trigger}
  </TooltipTrigger>,
  document.getElementById('root')
);

TooltipTrigger is the only component exposed by the package. It's just a positioning engine. What to render is left completely to the user, which can be provided using render props. Your props should be passed through getTriggerProps, getTooltipProps and getArrowProps.

Quick start

If you would like our opinionated container and arrow styles for your tooltip for quick start, you may import react-popper-tooltip/dist/styles.css, and use the classes tooltip-container and tooltip-arrow as follows:

Tooltip.js

import React from 'react';
import TooltipTrigger from 'react-popper-tooltip';
import 'react-popper-tooltip/dist/styles.css';

const Tooltip = ({tooltip, children, hideArrow ...props}) => (
  <TooltipTrigger
    {...props}
    tooltip={({
      getTooltipProps,
      getArrowProps,
      tooltipRef,
      arrowRef,
      placement
    }) => (
      <div
        {...getTooltipProps({
          ref: tooltipRef,
          className: 'tooltip-container'
        })}
      >
        {!hideArrow && <div
          {...getArrowProps({
            ref: arrowRef,
            'data-placement': placement,
            className: 'tooltip-arrow'
          })}
        />}
        {tooltip}
      </div>
    )}
  >
    {({getTriggerProps, triggerRef}) => (
      <span
        {...getTriggerProps({
          ref: triggerRef,
          className: 'trigger'
        })}
      >
        {children}
      </span>
    )}
  </TooltipTrigger>
);

export default Tooltip;

Then you can use it as shown in the example below.

<Tooltip placement="top" trigger="click" tooltip="Hi there!">Click me</Tooltip>

Props

children

function({}) | required

This is called with an object. Read more about the properties of this object in the section "Children and tooltip functions".

tooltip

function({}) | required

This is called with an object. Read more about the properties of this object in the section "Children and tooltip functions".

defaultTooltipShown

boolean | defaults to false

This is the initial visibility state of the tooltip.

onVisibilityChange

function(tooltipShown: boolean)

Called with the tooltip state, when the visibility of the tooltip changes

tooltipShown

boolean | control prop

Use this prop if you want to control the visibility state of the tooltip.

react-popper-tooltip manages its own state internally. You can use this prop to pass the visibility state of the tooltip from the outside. You will be required to keep this state up to date (this is where onVisibilityChange becomes useful), but you can also control the state from anywhere, be that state from other components, redux, react-router, or anywhere else.

delayShow

number | defaults to 0

Delay in showing the tooltip (ms).

delayHide

number | defaults to 0

Delay in hiding the tooltip (ms).

placement

string | defaults to right

The tooltip placement. Valid placements are:

• auto
• top
• right
• bottom
• left

Each placement can have a variation from this list:

• -start
• -end

trigger

string | defaults to hover

The event that triggers the tooltip. One of click, hover, right-click, none.

getTriggerRef

function(HTMLElement) => void

Function that can be used to obtain a trigger element reference.

closeOnOutOfBoundaries

boolean | defaults to true

Whether to close the tooltip when it's trigger is out of the boundary.

usePortal

boolean | defaults to true

Whether to use React.createPortal for creating tooltip.

portalContainer

HTMLElement | defaults to document.body

Element to be used as portal container

followCursor

boolean | defaults to false

Whether to spawn the tooltip at the cursor position.

Recommended usage with hover trigger and no arrow element

modifiers

object

Modifiers passed directly to the underlying popper.js instance. For more information, refer to Popper.js’ modifier docs

Modifiers, applied by default:

{
  preventOverflow: {
    boundariesElement: 'viewport'
  }
}

Children and tooltip functions

This is where you render whatever you want. react-popper-tooltip uses two render props children and tooltip. Children prop is used to trigger the appearance of the tooltip and tooltip displays the tooltip itself.

You use it like so:

const tooltip = (
  <TooltipTrigger
    tooltip={tooltip => (<div>{/* more jsx here */}</div>)}
  >
    {trigger => (<div>{/* more jsx here */}</div>)}
  </TooltipTrigger>
)

prop getters

See the blog post about prop getters

These functions are used to apply props to the elements that you render. It's advisable to pass all your props to that function rather than applying them on the element yourself to avoid your props being overridden (or overriding the props returned). For example <button {...getTriggerProps({onClick: event => console.log(event))}>Click me</button>

children function

property	type	description
getTriggerProps	function({})	returns the props you should apply to the trigger element you render.
triggerRef	node	returns the react ref you should apply to the trigger element.

tooltip function

property	type	description
getTooltipProps	function({})	returns the props you should apply to the tooltip element you render.
tooltipRef	node	return the react ref you should apply to the tooltip element.
getArrowProps	function({})	return the props you should apply to the tooltip arrow element.
arrowRef	node	return the react ref you should apply to the tooltip arrow element.
placement	string	return the placement of the tooltip.

Inspiration and Thanks!

This library is based on react-popper, the official react wrapper around Popper.js.

Using of render props, prop getters and doc style of this library are heavily inspired by downshift.
