Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Popper

A React hooks wrapper for popper.js to dynamic positioning of containers around a reference.

This is an internal hook of Chakra-UI, and it's not covered by semver, and may cause unexpected or broken application behavior. Use them at your own risk.

Installation

yarn add @chakra-ui/popper

Basic usage

By default, the usePopper hook returns props for the popper, reference and arrow.

import { Box } from "@chakra-ui/layout"
import { Button } from "@chakra-ui/button"
import { useDisclosure } from "@chakra-ui/hooks"
import { usePopper } from "@chakra-ui/popper"

function Example() {
  const { isOpen, onToggle } = useDisclosure()
  const { popperRef, referenceRef, getArrowProps } = usePopper()
  return (
    <>
      <Button ref={referenceRef} onClick={onToggle} mb={2}>
        {isOpen ? "Click me to see less" : "Click me to see more"}
      </Button>
      {isOpen && (
        <Box ref={popperRef} bg="red">
          <div
            {...getArrowProps({
              style: {
                background: "red",
              },
            })}
          />
          This is a popover for the button!
        </Box>
      )}
    </>
  )
}

Parameters

Changing the placement

You can change the placement of the popper by passing the placement option to usePopper and set it to the popper.js placement.

const { popperRef, referenceRef } = usePopper({
  placement: "right-start",
})

Match reference's width

In some cases, you might want to allow the popper take the width of the reference. For example, autocomplete, select, etc.

To achieve this, pass the matchWidth option and set it to true

const { popperRef, referenceRef } = usePopper({
  matchWidth: true,
})

Place the popper next to the reference

You can place the popper next to the reference without margin or distance between them. Useful to create an autocomplete or typeahead feature.

const { popperRef, referenceRef } = usePopper({
  gutter: 0,
})

Using inside a fixed container

If the reference element is inside a fixed container, you should use the fixed strategy.

const { popperRef, referenceRef } = usePopper({
  strategy: "fixed",
})

Adding transition

When add transitions to a popper component, it is usually advised to apply popper and transition to different elements.

// 1. Import components
import { useDisclosure } from "@chakra-ui/hooks"
import { usePopper } from "@chakra-ui/popper"
import { motion, AnimatePresence, Variants } from "framer-motion"

export function Example() {
  // 2. Create toggle state
  const { isOpen, onToggle } = useDisclosure()

  // 3. Create motion variants
  const slide: Variants = {
    exit: {
      y: -2,
      opacity: 0,
    },
    enter: {
      y: 0,
      opacity: 1,
    },
  }

  // 4. Consume the `usePopper` hook
  const { getPopperProps, getReferenceProps, getArrowProps, transformOrigin } =
    usePopper({
      placement: "bottom-start",
    })

  return (
    <>
      <button {...getReferenceProps({ onClick: onToggle })}>Toggle</button>
      <div {...getPopperProps()}>
        <AnimatePresence>
          {isOpen && (
            <motion.div
              transition={{
                type: "spring",
                duration: 0.2,
              }}
              variants={slide}
              initial="exit"
              animate="enter"
              exit="exit"
              style={{
                background: "red",
                width: 200,
                transformOrigin,
                borderRadius: 4,
              }}
            >
              Testing
              <div
                {...getArrowProps({
                  style: {
                    background: "red",
                  },
                })}
              />
            </motion.div>
          )}
        </AnimatePresence>
      </div>
    </>
  )
}

When not rendering the popper conditionally, we recommend using visibility: hidden instead of hidden or display: none
