Elastical

Elastical is a Node.js client library for the ElasticSearch REST API.

It's not quite finished, but what's done so far has doc comments and unit tests. Keep an eye on this repo for updates.

Installing

Latest released version:

npm install elastical

Latest dev code:

npm install https://github.com/rgrove/node-elastical/tarball/master

Basic Usage

Require elastical:

var elastical = require('elastical');

Instantiate an Elastical client that will connect to http://127.0.0.1:9200:

var client = new elastical.Client();

Or specify a custom host and port:

var client = new elastical.Client('example.com', {port: 1234});

Index a document:

// Specify the index name, document type, and document to index.
client.index('blog', 'post', {
    title: "Welcome to my stupid blog",
    body : "This is the only thing I'll ever post.",
    tags : ["welcome", "first post", "last post"]
}, function (err, res) {
    // `err` is an Error, or `null` on success.
    // `res` is the parsed ElasticSearch response data.
});

Retrieve a previously-indexed document by id:

// Specify the index and the document id.
client.get('blog', '42', function (err, doc, res) {
    // `err` is an Error, or `null` on success.
    // `doc` is the parsed document data.
    // `res` is the full parsed ElasticSearch response data.
});

Perform a search:

// Simple string query (automatically turned into a query_string query).
client.search({query: 'welcome'}, function (err, results, res) {
    // `err` is an Error, or `null` on success.
    // `results` is an object containing search hits.
    // `res` is the full parsed ElasticSearch response data.
});

// Custom query options (this is equivalent to the previous example, just
// without the magic).
client.search({
    query: {query_string: {query: 'welcome'}}
}, function (err, results, res) {
    // ...
});

See the doc comments in the source for more details on available methods and options.

Developing

Fork the git repo, clone it, then install the dev dependencies.

cd elastical
npm install

Make your changes, add tests, then run the tests to make sure nothing broke.

make test

This will run both offline and online tests. Online tests require an ElasticSearch server running at http://127.0.0.1:9200/. If you only want to run the offline tests (which don't require a server), run:

make offline-tests

Pull Requests

Before embarking on any major changes, please drop me a note first just to make sure I'm not already working on something similar. This could save us both some trouble.

Please make your changes in a topic branch and submit a pull request describing what the changes do and why I should merge them. Save time by including good offline and online tests for your changes (if you don't, I'll just ask you to add them). Thanks!

Support

Nope.
