React component that renders Input with debounced onChange
React component that renders an Input, Textarea or other element with debounced onChange. Can be used as drop-in replacement for <input type="text" /> or <textarea />

npm install --save react-debounce-input
yarn add react-debounce-input
<script src="https://unpkg.com/react@16.0.0/umd/react.production.min.js"></script> <script src="https://unpkg.com/react-debounce-input/build/react-debounce-input.js"></script> (Module exposed as `DebounceInput`)
import React from 'react'; import ReactDOM from 'react-dom'; import {DebounceInput} from 'react-debounce-input'; class App extends React.Component { state = { value: '' }; render() { return ( <div> <DebounceInput minLength={2} debounceTimeout={300} onChange={event => this.setState({value: event.target.value})} /> <p>Value: {this.state.value}</p> </div> ); } } const appRoot = document.createElement('div'); document.body.appendChild(appRoot); ReactDOM.render(<App />, appRoot);
You can specify element="textarea". For Example:
<DebounceInput element="textarea" />
Will result in
<textarea />
Note: when rendering a <textarea /> you may wish to set forceNotifyByEnter = {false} so the user can make new lines without forcing notification of the current value.
This package has only been tested with <input /> and <textarea /> but should work with any element which has value and onChange props.
You can also use a custom react component as the element. For Example:
<DebounceInput element={CustomReactComponent} />
Will result in
<CustomReactComponent />
Function called when value is changed (debounced) with original event passed through
Value of the Input box. Can be omitted, so component works as usual non-controlled input.
Minimal length of text to start notify, if value becomes shorter then minLength (after removing some characters), there will be a notification with empty value ''.
Notification debounce timeout in ms. If set to -1, disables automatic notification completely. Notification will only happen by pressing Enter then.
Notification of current value will be sent immediately by hitting Enter key. Enabled by-default. Notification value follows the same rule as with debounced notification, so if Length is less, then minLength - empty value '' will be sent back.
NOTE if onKeyDown callback prop was present, it will be still invoked transparently.
Same as forceNotifyByEnter, but notification will be sent when focus leaves the input field.
Will pass ref={inputRef} to generated input element. We needed to rename ref to inputRef since ref is a special prop in React and cannot be passed to children.
See ./example/Ref.js for usage example.
<DebounceInput type="number" onChange={event => this.setState({value: event.target.value})} placeholder="Name" className="user-name" />
Will result in
<input type="number" placeholder="Name" className="user-name" />
This library has typescript typings, import them the same way as in javascript:
import {DebounceInput} from 'react-debounce-input';
Also there are helper types DebounceTextArea and Debounced to provide strict interfaces for wrapping components different from standard <input />. Check usage examples in example/typescript-example.tsx.
NOTE library author is not using Typescript, so if you are using typings and found an issue, please submit a PR with fix. Thanks @iyegoroff for the initial TS support!
Currently is being developed and tested with the latest stable Node on OSX.
To run example covering all DebounceInput features, use yarn start, which will compile example/Example.js
git clone git@github.com:nkbt/react-debounce-input.git cd react-debounce-input yarn install yarn start # then open http://localhost:8080
# to run ESLint check yarn lint # to run tests yarn test
