es-query-builder

es-query-builder

build elasticsearch queries the sane way

Motivation

the elasticsearch json query syntax is painful

Setup

es-query-builder expects both ES_URL and ES_INDEX environment variables to be definied

so you may have a config file that looks something like:

export ES_INDEX=events
export ES_URL=https://mysearch:9200

Usage

var Query = require('es-query-builder')

// create a fresh query:
var q = new Query

// chain modifications:
q.size(10) 
q.queryString('event.type:foo')
q.range('timestamp', 1467817775660, 1467817785860)
q.agg('min', 'min_timestamp', 'timestamp')
q.agg('max', 'max_timestamp', 'timestamp')

// call it!
q.fetch() // no args returns a promise

q.fetch(function(err, res) {
  // or with callback 
})
