react-debounce-render

react-debounce-render is a Higher Order Component that wraps your react components and debounces their rendering.

This method can be used to prevent extra renders when a react component rapidly receives new props by delaying the triggering of the render until updates become less frequent. Doing so will improve the overall rendering time of the application, thus improve the user experience. It uses lodash debounce under the hood.

Rationale:

Sometimes it's difficult, impractical or impossible to batch props updates before they're passed down to a react component, resulting in a react component being rendered too often while only the last props update might have been useful and should have triggered a rendering of the component. In these cases, debouncing the rendering of a react component may be the only solution to improve performance.

react-debounce-render is a react component that will wrap any of your react components, persist the last props update that was received while discarding the previous ones, and only rendering the wrapped component when no new updates has been received in the last few milliseconds by default. Since the debounce function used under the hood is lodash's debounce, you may also pass in a few options such as the number of milliseconds to delay the render by, a maximum delay, or whether to call render on a leading or trailing edge of the timeout.

Usage:

Default usage:

import debounceRender from 'react-debounce-render';

const debouncedMyReactComponent = debounceRender(MyReactComponent);

// do whatever you want with the debounced component such as connecting to a redux store:
connect(state => {
    myProp: (state) => getProp(state)
})(debouncedMyReactComponent);

With options:

See lodash debounce for all options. Debounce render takes its parameters similarily to lodash debounce:

import debounceRender from 'react-debounce-render';

const debouncedMyReactComponent = debounceRender(MyReactComponent, 100, { leading: false });

Changelog

5.0.0 - OCT 04 2018

There is no breaking change in this version despite the major version change, this is only to highlight the fact that most of the internal implementation has changed since PR #12.

Removes unused lodash dependency since we're using lodash/debounce. Thanks @yched for raising the issue!
Using @yched cleaner implementation which doesn't use the deprecated lifecycle methods nor trigger any warning. See Issue #11.

4.0.3 - JULY 19 2018

Revert 4.0.2 change and use latest lodash version again, though importing lodash/debounce directly. Thanks @faizrr for raising the issue!

4.0.2 - JULY 6 2018

Use lodash.debounce instead of lodash to reduce built package size. Thanks @faizrr for raising the issue!

4.0.1 - APRIL 3 2018

Ensure that debounce is properly canceled when the component is unmounted which removes the "Warning: Can only update a mounted or mounting component." warning. Resolves Issue #5. Thanks @mjhm for the fix.

4.0.0 - NOVEMBER 20 2017

Move react to the peerDependencies in package.json and accept major versions greater than 15. Resolves Issue #4. Thanks @TheSharpieOne for raising the issue.

3.0.0 - AUGUST 16 2017

import debounceRender from 'react-debounce-render' should now consistently work. See Issue #2. Thanks @CameronAckermanSEL for raising the issue. As a result, using a destructuring assignment in the import statement (import { debounceRender } from 'react-debounce-render'') shouldn't accidentally work anymore which is a potential breaking change.

2.0.0 - JULY 31 2017

Module isn't built as standalone before being published to npm, resulting in a cleaner and lighter package. Also removes non lib related files from the package. See PR #1. Thanks @wbazant for the contribution.

1.0.0 - JUNE 25 2017

debounces a React component's render method()
includes e2e tests and documentation
