A simple way to do a debounce with Vue (not dependencies required)

debounce.vue

<template>
<input type=text v-model='value' @kepup='debounceExpensiveMethod' />
</template>
<script>
export default {
  name: 'SomeComponent',
  data () {
    return {
      timeout: null
    }
  },
  methods: {
    debounceExpensiveMethod () {
      if (this.timeout) {
        window.clearTimeout(this.timeout)
      }
      this.timeout = window.setTimeout(this.expensiveMethod, 1000)
    },
    expensiveMethod () {
    }
  }
}
</script>
