simple elasticsearch client for node.js
Latest commit d0d3dca Nov 5, 2014 @printercu Update
Added notice about ruby version


Simple & handy client for elasticsearch. It's just a wrapper around http.request with shortcuts for elasticsearch.

It implements all available functionality & even upcoming.

Be careful while using settings for default type & index: they are client's instance variables. So if you are going to have one client in an application you'd better set them explicitly in each call. JS is so asynchronous...

Looking for easy indices and mappings management with zero-downtime migrations? Check out ruby version.


Elastics = require 'elastics'
es = new Elastics
  host:  hostname # default 'localhost'
  port:  port     # default 9200
  index: index    # default null
  type:  type     # default null

This params are stored in es.defaults. You can change them with:

  • setIndex(index, [type = null])
  • setType(type)

For the first time I've made all the methods adaptive to arguments. But then there have appeared to much significant arguments so I gave it up.

So all the methods take two args: object with parameters & callback. For now you can omit callback but not params.

params fields:

  • method - http request method
  • index
  • type
  • path - last part for url
  • id - same as path but with higher priority
  • query - query string for url. you can set routing params here
  • data - request body

You can omit fields stored in defaults

lowest level

request(params, [callback])

request-type level

get(), put(), post(), delete() - just set the method

highest level

  • putMapping() - put with path = '_mapping'
  • search() - post with path = '_search'
  • index() - if id field is set then put else post

few examples

# index:null, type: null

es.get {}
# GET http://host::port/ index: 'index'
# POST http://host::port/index

es.setIndex 'other_index', 'type'
mapping = type:
    field_one: type: 'string'
es.putMapping data: mapping
# PUT http://host::port/other_index/type/_mapping
# body is json of mapping

es.get index: 'one', type: 'two', id: 'three'
# GET http://host::port/one/two/three
