useThrottle

useThrottle adds the ability to specify an array "throttles" of functions to throttle.

All you need to do is to add a static array of function names throttles, as you would define your targets. Then call useThrottle(this) in your connect() callback and your functions are throttled.

Reference

useThrottle(controller, options = {})

controller: A Stimulus Controller (usually 'this')

options:

Option	Description	Default value
wait	The number of milliseconds to wait	200

Example:

import { ApplicationController, useThrottle } from 'stimulus-use'

export default class extends ApplicationController {
  static throttles = ['add']

  connect() {
    useThrottle(this, { wait: 100 })
  }

  add() {
    // this function is throttled.
  }

  instant() {
    //this function is not throttled.
  }
}

Per function wait option

If you need to set a different wait option for each function, you can specify it within the throttles array like so :

export default class extends ApplicationController {
  static throttles = [
    'click',
    {
      name: 'fetch',
      wait: 500
    }
  ]

  connect() {
    useThrottle(this, { wait: 100 })
  }

  click() {
    // this function is throttled with a wait time of 100ms.
  }

  fetch() {
    // this function is throttled with a wait time of 500ms.
  }

  instant() {
    // this function is not throttled.
  }
}
