A simple javascript library for working with ElasticSearch.
It also provides a backend interface to ElasticSearch suitable for use with the Recline suite of data libraries.
The library requires:
- underscore
- jQuery (for Ajax requests)
Load the library in your web page, e.g. do:
<script type="text/javascript" src="http://okfnlabs.org/elasticsearch.js/elasticsearch.js"></script>
(You can replace the src url with the url to your copy of elasticsearch.js).
Here's an example of using the library to create, get and query some data.
// Your ElasticSearch instance is running at http://localhost:9200/
// We are using index 'twitter' and type (table) 'tweet'
var endpoint = 'http://localhost:9200/twitter/tweet';
// Table = an ElasticSearch Type (aka Table)
// http://www.elasticsearch.org/guide/reference/glossary/#type
var table = ES.Table(endpoint);
// Create some data
table.upsert({
id: '123',
title: 'My new tweet'
}).done(function() {
// now get it
table.get('123').done(function(doc) {
console.log(doc);
});
});
// Query for data
// Queries follow Recline Query spec -
// http://okfnlabs.org/recline/docs/models.html#query-structure
// (very similar to ES)
table.query({
q: 'hello'
filters: [
{ term: { 'owner': 'jones' } }
]
}).done(function(out) {
console.log(out);
});
// get the mapping for this "table"
// http://www.elasticsearch.org/guide/reference/glossary/#mapping
table.mapping().done(function(theMapping) {
console.log(theMapping)
});
