Exploring Vue.js integration with Elasticsearch API functions

I have a script written in Vue.js and I am looking to incorporate an Elasticsearch API method.

// ./main.js
var Vue = require('vue');

Vue.use(require('vue-resource'));

import ES from './elasticsearch.js';

new Vue({

    el: 'body',

    methods: {
        search: function() {
            // need to implement calling the es.search method here...
        }
    }
});

Here is the Elasticsearch script for reference:

// ./elasticsearch.js
var es = require('elasticsearch');

var client = new es.Client({
  host: 'localhost:9200'
  ,log: 'trace'
});

client.search({
  index: 'my_index',
  type: 'my_type',
  body: {
    fields: {},
    query: {
      match: {
        file_content: 'search_text'
      }
    }
  }
}).then(function (resp) {
    var hits = resp.hits.hits;
}, function (err) {
    console.trace(err.message);
});

My goal is to call the client.search method within the search method in main.js and send the search text to my server. How can this be achieved? Is there a way to access and use the elasticsearch object within a vuejs method?

Any suggestions or guidance would be greatly appreciated!

Answer №1

your elasticsearch.js file needs to be properly configured as a module: import ES from './elasticsearch'. This code won't work because the file is not exporting anything.

A correct setup should resemble this:

// ./elasticsearch.js
var es = require('elasticsearch');

var client = new es.Client({
  host: 'localhost:9200',
  log: 'trace'
});

function search(myIndex, myType, searchText) {
    return client.search({
        index: myIndex,
        type: myType,
        body: {
            fields: {},
            query: {
                match: {
                    file_content: searchText
                }
            }
        }
    }).then(function(resp) {
        return hits = resp.hits.hits;
    }, function(err) {
        console.trace(err.message);
    });
}

export { search };

We have defined a function called search and exported it with proper return statements to handle Promise responses.

In your main.js file, you can import the function and use it like this:

// ./main.js
var Vue = require('vue');

Vue.use(require('vue-resource'));

import { search } from './elasticsearch.js';

new Vue({

    el: 'body',

    methods: {
        search: function() {
            var result = search('someindex', 'sometype', 'Search text here').then(function(res) {
                // do something with the result
            })
        }
    }
});

If the "resp.hits.hits" in your code represents the search result as a JSON Object Array, then you can set up your Vue instance like this:

// ./main.js
var Vue = require('vue');

Vue.use(require('vue-resource'));

import ES from './elasticsearch.js';

new Vue({

    el: 'body',
    data:{
       searchResults:[] //specifying that it is an array
    }

    methods: {
        search: function() {
           var self = this;
           // make the search and fetch response data
           client.search(function(resp){
                self.searchResults = resp.hits.hits
           })
        }
    }

});

Then, in your HTML, simply bind the DOM to searchResults.
