ElementTarget is a union type that represents the various types of elements that can be targeted in React.


  • It's common to access elements in React for actions like clicking, hovering, etc.
  • Traditional methods include using Ref or DOM queries, which can be challenging in Server-side Rendering (SSR) environments.
  • To enhance Developer Experience (DX) and support for SSR, we introduce useTargetElement.
  • It's a SSR friendly React Hook that simplifies the process of targeting elements.

Frequently, React Hooks require access to DOM elements to perform actions such as clicking outside a component (useClickAway), hovering (useHover), or scrolling (useScroll).

Traditionally, there are mainly two methods to access HTML elements in React:

  • React Ref: Attach a Ref to an element using ref={ref} and access it via ref.current.
  • DOM Query: Directly obtain the element using the document's method, like querySelector.
// React Ref
useEffect(() => {
if (ref.current) {
// do something with ref.current
}, [])

// DOM Query
useEffect(() => {
const el = document.getElementById('target')
// do something with el
}, [])

While these approaches work well, they introduce challenges in SSR environments where direct access to elements or browser-specific objects during the render stage isn't possible. Instead, developers must utilize useEffect or Ref to access these elements or objects on the client side.

Additionally, it is often desirable to access an element directly by passing a Ref, a common requirement in many Hooks and daily use scenarios.

Introducing useTargetElement

To address these issues, we've created the useTargetElement Hook, which simplifies the process of obtaining a target element. This Hook returns a React Ref containing the target element:

const targetRef = useTargetElement(elementTarget)

It accepts a getter function as input to avoid SSR-related errors and also supports a Ref containing the element to enhance DX and accommodate a broad range of use cases.

This Hook has found its place in numerous Hooks that require element targeting. It represents a best practice for developers needing to access elements within their Hooks.

ElementTarget Types


A "🚥" prefix indicates that the target can be a getter function, which is particularly useful in SSR contexts. The "⚛️" prefix denotes that the target can be a Ref that contains it.

  • 🚥 ⚛️ window/document: The global window or document object.
  • 🚥 ⚛️ Element: Any HTML element.
  • 🚥 ⚛️ Element Selector: A CSS selector string, such as #id, .class.subclass, tag, etc.
  • 🚥 ⚛️ null/undefined: These indicate the absence of a target, simplifying error handling while ensuring smooth integration with TypeScript.

Valid Examples

const ref = useRef<HTMLDivElement>(null) // <div ref={ref} />
const targetRef = useTargetElement(ref)

const targetRef = useTargetElement('#my-div')
const targetRef = useTargetElement('#my-div .container')

const targetRef = useTargetElement(() => window)
const targetRef = useTargetElement(() => document.getElementById('my-div'))

// NOT recommended, will cause SSR issues
const targetRef = useTargetElement(window)
// NOT recommended, will cause SSR issues
const targetRef = useTargetElement(document.getElementById('my-div'))
