Question

Creating an asynchronous function in a Vue.js component that utilizes the Lodash library

I'm struggling with writing an async function correctly. Can someone provide guidance on how to achieve this?

async search (loading, search, vm) {
  let vm = this
  _.debounce(() => {
    let ApiURL = '/users/'
  }

  let { res } = await api.get(ApiURL) //Error
    vm.options = res.data
  }, 800)

Answer №1

Avoid using the debounce function from Lodash with promises because it doesn't differentiate between synchronous and asynchronous functions. It behaves as if the function provided is synchronous, not waiting for the promise to resolve or reject before returning. This can lead to issues where the function execution time does not account for delays, such as network requests potentially returning in a different order.

Consider utilizing the awesome-debounce-promise library from npm instead.

To utilize the lodash function as a component method, simply assign it directly.

new Vue({
    el: '#app',
    data: { requests: 0 },


  methods: {
    search: _.throttle(async function () {  
      const res = await fetch('/echo/json/')
      this.requests++
      console.log(res)
    }, 1000)
  },


  created () {
    // 100ms interval but throttle works at 1000ms
    setInterval(() => {
        this.search()
    }, 100)
  }
})

If you are facing a similar scenario:

methods: {
    search: _.debounce(async function () {
      // this code may differ from your actual implementation
      const res = await api.get('/users/')
      this.options = res.data
    }, 1000)
  }
}
