<script src="https://unpkg.com/vue-bootstrap-typeahead"></script>

Usage

Import and register the component

import VueBootstrapTypeahead from 'vue-bootstrap-typeahead'

// Global registration
Vue.component('vue-bootstrap-typeahead', VueBootstrapTypeahead)

// OR

// Local registration
export default {
    components: {
        VueBootstrapTypeahead
    }
}

Basic Usage

The only required attribute is a data array.

<vue-bootstrap-typeahead 
  v-model="query"
  :data="['Canada', 'USA', 'Mexico']"
/>

Working with API's

The typeahead does not fetch any data, for maximum flexibility it will only work with already loaded API responses in the form of arrays. The serializer attribute allows you to define a function to turn each array item in the response into a text string, which will appear in the results.

<template>
  <vue-bootstrap-typeahead
    :data="addresses"
    v-model="addressSearch"
    size="lg"
    :serializer="s => s.text"
    placeholder="Type an address..."
    @hit="selectedAddress = $event"
  >
</template>

<script>
import _ from 'underscore'

const API_URL = 'https://api-url-here.com?query=:query'

export default {
  name: 'TestComponent',

  data() {
    return {
      addresses: [],
      addressSearch: '',
      selectedAddress: null
    }
  },

  methods: {
    async getAddresses(query) {
      const res = await fetch(API_URL.replace(':query', query))
      const suggestions = await res.json()
      this.addresses = suggestions.suggestions
    }
  },

  watch: {
    addressSearch: _.debounce(function(addr) { this.getAddresses(addr) }, 500)
  }
}
</script>
