ElasticSearch Tool Kit

Makes life easy with ElasticSearch.

elastic = require('elasticsearch');
Etk = require('etk');

// Elasticsearch instance is initialized as documented at it's
// project space
var client = elastic.Client({hosts: ['localhost:9200']});

// Etk instance "tk_1" calls against index = my_index and type = my_type
var tk_1 = Etk(client, {index: "my_index", type: "my_type"});

// search Etk API call returns back the search result
tk_1.search("foo", "bar", function (err, resp) {

    // Etk inserts "source()" method to response, so you can easily get 
    // the data array found in search
    console.log(JSON.stringify(resp.source());
    
    // Etk inserts "score()" method to response, so you can easily get 
    // the score array found in search
    console.log(JSON.stringify(resp.score());
            
    // elasticsearch original response can be reached from resp.resp 
    // for further data manipulation for special cases.
    console.log(JSON.stringify(resp.resp);
});

// Etk instance "tk_2" forwards elasticsearch error and response messages
// to application. See class documentation for full list of options
// you can configure
var tk_2 = Etk(client, {index: "another_index",
                        type: "another_type",
                        raw_response: true,
                        raw_error: true});

// search Etk API call returns back the search result
tk_2.search("baz", "bar", function (err, resp) {

        // Application should handle raw error and response messages
        // received from elasticsearch.
        ...
});

Installation

$ npm install etk

Features

• Provides high level, easy to use interface for Elastic Search in your Node.js project.
• Etk extents the official elasticsearch project with well documented function calls.
• Parses elasticsearch error and response messages in useful ways. Yet you have the option to receive them as they are with configuration options.
• Uses same elasticsearch instance in multiple Etk clients.
• All API calls are tested against the latest elasticsearch release.
• Elasticsearch can be used alongside with Etk without any code change.

API Documentation with Examples

Project site documents the latest NPM release.

TODO

• Currently project covers a very small subset of possible function calls. Please extend the library and open a pull request for merge.
• Promise support is missing. Only callback mechanism is implemented.
• Browser support is not available yet.
