build status Elastic Search Client

A node.js client for elasticsearch (http://www.elasticsearch.com).

Installation

npm install elasticsearchclient

Executing commands on elasticsearch

ElasticSearchClient = require('elasticsearchclient');

var serverOptions = {
    host: 'localhost',
    port: 9200,
    pathPrefix:'optional pathPrefix',
    secure: true||false,
    //Optional basic HTTP Auth
    auth: {
   	username: process.env.ES_USERNAME,
    	password: process.env.ES_PASSWORD
  }
};



OR specify multiple hosts

var serverOptions = {
    hosts:[
        {
            host: 'localhost',
            port: 9200
        }]
};
var elasticSearchClient = new ElasticSearchClient(serverOptions);

var qryObj = {
    field : term
}

elasticSearchClient.search('my_index_name', 'my_type_name', qryObj)
    .on('data', function(data) {
        console.log(JSON.parse(data))
    })
    .on('done', function(){
        //always returns 0 right now
    })
    .on('error', function(error){
        console.log(error)
    })
    .exec()

//Canonical search
 elasticSearchClient.search('my_index_name', 'my_type_name', qryObj, function(err, data){
    console.log(JSON.parse(data))
 })

//Search call as a reusable object with a canonical callback
mySearchCall = elasticSearchClient.search('my_index_name', 'my_type_name', qryObj);
//Do it once
mySearchCall.exec(function(err, data){
    console.log(JSON.parse(data))
})
//Do it twice
mySearchCall.exec(function(err, data){
    console.log(JSON.parse(data))
})



elasticSearchClient.index(indexName, typeName, document, id, options)
    .on('data', function(data) {
        console.log(data)
    })
    .exec()

//Bulk index example
var commands = []
commands.push({ "index" : { "_index" :'my_index_name', "_type" : "my_type_name"} })
commands.push({field1:'value',field2:'value'})


    elasticSearchClient.bulk(commands, {})
            .on('data', function(data) {})
            .on('done', function(done){})
            .on('error', function(error){})
            .exec();

Twitter stream: Seems to be a problem in the es with deleting streams. May require a node restart for modifications/deletes to take effect

elasticSearchClient.createOrModifyTwitterRiver(riverName, riverData)
    .on('data', function (data) {
        console.log(data)
        assert.ok(JSON.parse(data).ok)
    })
    .on('error',
    function (error) {
        console.log(error)
        assert.ok(false)
    }).exec()
