dejaVu - the missing web UI for elasticsearch

GitHub License Code Climate GitHub Stars

dejaVu fits the unmet need of being a modern Web UI for Elasticsearch. Existing UIs were either built with a legacy UI and have left much to be desired from a Ux perspective or have been built with server side page rendering techniques (I am looking at you, Kibana).

Thus started the journey of dejaVu, with a goal of 100% client side rendering and usage of modern UI elements (zero page reloads, infinite scrolling, filtered views). It’s available as a github hosted page, chrome app and as an Elasticsearch plugin.

Elasticsearch plugin - Installation

bin/plugin install appbaseio/dejaVu

Note: To make sure you enable CORS settings for your ElasticSearch instance, add the following lines in the ES configuration file.

 http.port: 9200
 http.cors.allow-origin: ""
 http.cors.enabled: true
 http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length, Authorization
 http.cors.allow-credentials: true

After installing the plugin, start elasticsearch service


and visit the following URL to access it. 

Note: If you use Elasticsearch from a different port, the URL to access and the http.cors.allow-origin value in the configuration file would change accordingly.


dev branch is the bleeding edge version of dejavu, all new changes go here.

master branch is more suitable for installing dejavu locally. The Elasticsearch site plugin for dejavu uses master branch.

chrome-extension branch is where we make chrome app related changes. The main difference in the chrome app is the lack of support for the localStorage API (It has it’s own API, which is asynchronous in nature).

Local Installation

  1. git clone
  2. git checkout master
  3. npm install
  4. bower install
  5. gulp watch (runs dejavu on http://localhost:1358)


The source code is under the _site/src directory. You can make pull requests against the dev branch.


Filter Views

Filter Views

Sort through the data, find things visually, hide irrelevant data and make sense of all the numbers and dates. Filters work by identifying data mappings from the Elasticsearch index. If dejavu sees a string field, it will provide filters for search, has and has not and is also mindful if the data is analyzed. Similarly a numeric field allows filtering on ranges and a date field allows filtering data by dates.

dejavu also supports local filters like column sorting and showing a subset of columns.

To-do: dejavu doesn’t support filtering on advanced data types (like geopoint, parent-child); but it’s possible to add those at some point.

Modern UI elements


It’s not uncommon to have thousands of records in a type. dejavu supports an infinite scroll based UI, pagination is so old school.

dejavu also supports browsing data from multiple types and bulk deletions. It also let’s you add new records and update existing records.

Realtime data updates

dejavu uses a websockets based API and subscribes for data changes for the current filtered view. For this to work, the Elasticsearch server needs to support a websockets based publish API. Currently, you can take advantage of this feature by hosting your data with

Modern UI Built with React v0.14.0, uses a live-reload interface. Built with jQuery v1.6.1, slightly stodgy Built with Angular 1.x Built with ExtJs, but a bit stodgy Built with Node.JS, Hapi, Jade
Browser features CRUD with support for data filters. Read data with support for full-text search. No data view Data view support for a single type Read view with support for visualizations / charting

Here’s a rough roadmap of things to come in the v1.0 release.

  • Create a test coverage suite
  • Battle-testing with different datasets
  • Feature support for advanced filtering
  • Offline detection and reconnection for realtime updates
  • Performance improvements while scrolling
