React hook that triggers a callback after hot-module reloading has been performed
use-hot-module-reload
React hook that triggers a callback after hot-module reloading has been performed (for any module, not just the one it was used in).
Works with modern versions of Webpack and Vite. Other bundlers may be added if they expose a way to listen for updates.
Installation
npm install --save use-hot-module-reload
Usage
import {useState, useCallback} from 'react'
import {useHotModuleReload} from 'use-hot-module-reload'
export function MyComponent() {
const [lastHMRed, setLastHMRed] = useState('')
const updateHMRTime = useCallback(() => setLastHMRed(new Date().toISOString()), [])
useHotModuleReload(updateHMRTime)
return <div>{lastHMRed && `Last hot module reload at: ${lastHMRed}`}</div>
}
