Getting set up
Install
npm install @wethegit/react-modal
CSS
Import this wherever it makes sense to, based on your project structure:
import "@wethegit/react-modal/style.css"
Usage
The useModal
hook provides mechanisms for hooking into the modal state. We'll need to pass said state
to the <Modal>
component, as shown below. This approach allows us to abstract away state management, which becomes especially useful when using a URL hash to manage the modal's state.
The snippet below demonstrates the minimum required setup. No focus management, no animations.
import {
Modal,
ModalBackdrop,
ModalContent,
useModal
} from "@wethegit/react-modal"
function MyModal() {
const { isOpen, toggle } = useModal()
return (
<>
<button onClick={toggle}>
Open the modal window!
</button>
{isOpen && (
<Modal>
<ModalBackdrop onClick={toggle} />
<ModalContent>
<button onClick={toggle}>Close</button>
<p>Voluptate Lorem ut minim excepteur sit fugiat anim magna aliquip.</p>
</ModalContent>
</Modal>
)}
</>
)
}
Using a URL hash to manage the modal state
It's as easy as passing a hash
prop to the useModal
hook. The hook will then use the URL hash to manage the modal's state. This is useful for when you want to allow your users to share a link to a modal window, or when you want to allow your users to navigate to a modal window via a URL.
import {
Modal,
ModalContent,
ModalBackdrop,
useModal
} from "@wethegit/react-modal"
function MyModal() {
const { isOpen, toggle } = useModal({
hash: "my-modal-hash"
})
return (
<>
<button onClick={toggle}>
Open the modal window!
</button>
{isOpen && (
<Modal>
<ModalBackdrop onClick={toggle} />
<ModalContent>
<button onClick={toggle}>Close</button>
<p>Voluptate Lorem ut minim excepteur sit fugiat anim magna aliquip.</p>
</ModalContent>
</Modal>
)}
</>
)
}
Full example
Custom transition, focus management and hash-based state management.
Use your favorite animation library, @wethegit/react-hooks provides a simple one for these cases.
import { useRef } from 'react'
import { useAnimatePresence } from '@wethegit/react-hooks'
import {
Modal,
ModalContent,
ModalBackdrop,
useModal
} from "@wethegit/react-modal"
function MyModal() {
const triggerButton = useRef(null)
const modalRootRef = useRef(null)
const { isOpen, toggle } = useModal({
// `triggerRef` allows the focus to shift to whatever triggered the modal
triggerRef: triggerButton,
// `hash` will automatically open the modal when hash changes and will also update the hash when the modal opens/closes
hash: "modal-with-hash",
})
const { render, animate } = useAnimatePresence({
isVisible: isOpen,
duration: 800
})
return (
<>
<button ref={triggerButton} onClick={toggle}>
Open the modal window!
</button>
<div ref={modalRootRef}></div>
{render && modalRootRef.current && (
<Modal
renderTo={modalRootRef.current}
style={{
transition: `opacity 800ms ease-in-out`,
opacity: animate ? 1 : 0
}}>
<ModalBackdrop onClick={toggle} />
<ModalContent>
<button onClick={toggle}>
Close
</button>
<p>Voluptate Lorem ut minim excepteur sit fugiat anim magna aliquip.</p>
</ModalContent>
</Modal>
)}
</>
)
}
Props
<Modal>
| prop | type | default value | description | | -------------------- | --------- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | renderTo | HTMLElement | null | If a valid HTMLElement is provided, the modal will be appended to that element. Otherwise will be rendered in place. | | className | String | null | | | children | ReactNode | null | |
<ModalContent>
A wrapper for the modal's content. This component is optional, but it's recommended to use it for styling purposes.
Any valid <div>
props can be passed to this component.
<ModalBackdrop>
A wrapper for the modal's backdrop. This component is optional, but it's recommended to use it for styling purposes.
Any valid <div>
props can be passed to this component.
useModal
| prop | type | default value | description | | -------------------- | --------- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | hash | String | null | Optional. If provided, the hook will use the URL hash to manage the modal's state. This is useful for when you want to allow your users to share a link to a modal window, or when you want to allow your users to navigate to a modal window via a URL. | | triggerRef | RefObject | null | Optional. If provided, the hook will shift the user's focus to this element when the modal closes. |
Styling
The component comes with minimal and sensible defaults.
You can override these as you see fit and as your setup allows.
Accessibility
This component was built with focus accessibility best-practices at top-of-mind, and provides enough flexibility to allow you to create an accessible modal window.
Focus loop
There are hidden elements at the start and end of the modal component, which, on focus, shift the user's focus to either the end or start of the content, respectively.
Focus on close
The triggerRef
prop of the useModal
hook ensures that—on close of a modal—your user's focus is shifted back to where it was before opening the modal.
