useEventCallback

Overview

Copy the source into your project, then import the parts you need. Styles use local StyleX declarations and shared theme tokens. You can change the source without wrapping or replacing a package.

Installation

Run bunx @yopem-ui/cli init from your project root first. The CLI configures StyleX and installs shared files and dependencies.

bunx @yopem-ui/cli init

bunx @yopem-ui/cli add use-event-callback

Run from your project root. The CLI installs required components, shared files, and packages. Previews may need additional components. Existing files are preserved. To refresh installed source, use update; locally edited files need an explicit --force to overwrite.

bunx @yopem-ui/cli update use-event-callback

Preview

"use client"

import { Box } from "@/components/ui/box"
import { Button } from "@/components/ui/button"
import { VStack } from "@/components/ui/vstack"

Usage

The returned function keeps its identity and calls the latest committed callback. Arguments, return values, promises, and errors pass through unchanged.

Use it only for event handlers and effect callbacks, never during render. Calling it before the first commit throws. Updates publish during insertion effects, so aborted renders do not replace the committed callback.

Import from the local file installed by the CLI.

"use client"

import { Button } from "@/components/ui/button"
import { Box } from "@/components/ui/box"
import { VStack } from "@/components/ui/vstack"
import { useEventCallback } from "@/hooks/use-event-callback"
import { useState } from "react"

export function Preview() {
  const [count, setCount] = useState(0)

  const increment = useEventCallback(function () {
    setCount(count + 1)
  })

  return (
    <VStack>
      <Button onClick={increment}>Increment count</Button>
      <Box as="output">Count: {count}</Box>
    </VStack>
  )
}
