Async Throttler

This utility will delay the resolution of a promise until a delay has elapsed. It also exposes state of the passed promise so that ui events can be keyed off that.

Usage - AsyncThrottler

create

Pass in your state update handler so that you can receive throttler updates. Returns a throttler instance

import asyncThrottler from '@scoir/async-throttler';

class ExampleComp extends React.Component {
    componentWillMount () {
        this.throttler = asyncThrottler.create(state => this.setState(state))
    }
    ...
}

state update handler

When the throttler state changes, it will execute the callback that was passed into the create function. That object looks like this:

{
    isProcessing: <boolean>,
    isProcessed: <boolean>,
    isComplete: <boolean>,
    isError: <boolean>,
}

Usage - throttler instance

execute

Pass in the promise you would like to throttle and an optional delay (default is 700ms)

this.throttler.execute(this.doAsync());
this.throttler.execute(this.doAsync(), 1000);

reset

Restores the throttler instance state back to its initial state.

this.throttler.reset();

{
    isProcessing: false,
    isProcessed: false,
    isComplete: false,
    isError: false,
}
