dejavu is the missing web UI for Elasticsearch. Existing web UIs leave much to be desired or are built with server side page rendering techniques (I am looking at you, Kibana).
Thus started the journey of dejavu, with a goal to build a modern Web UI (no page reloads, infinite scroll, filtered views, realtime updates) with 100% client side rendering. It is available today as a hosted app, chrome extension and as a docker image.
Starting version 1.0.0, dejavu is the only web UI that supports importing data via JSON and CSV files.
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.
dejavu also supports query filtered view, where a user can write an Elasticsearch query and the data view will be filtered according to the query.
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.
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 appbase.io.
This newly supported feature allows importing CSV or JSON data directly into Elasticsearch through a guided data mappings configuration.

Here's a rough roadmap of things to come in the version 1.0.0 release.
🎆 We just hit the 1.0.0 roadmap.
- Battle-testing with different datasets
- Feature support for advanced filtering
Offline detection and reconnection for realtime updates - Performance improvements while scrolling
- Support for importing and exporting data
- Support for a continuous query view
- Available as a docker image
Roadmap for version 2.0.0 release, subject to change:
- An intuitive data editing experience in tabular mode (v/s JSON edit mode)
- View data types from within the data browser view
- A more streamlined import process
- Create a test coverage suite
dev branch is the bleeding edge version of dejavu, all new changes go here.
chrome-extension branch is where we make chrome extension related changes.
gh-pages branch is for the hosted app, as well as for the version that runs on https://dashboard.appbase.io.
- git clone https://github.com/appbaseio/dejavu
- git checkout master
- npm install
- bower install
- npm start (open dejavu in the browser on http://localhost:1358/live)
$ npm run build_chrome_extension$ npm run build_gh_pagesThe source code is under the live/src directory. You can make pull requests against the dev branch.
docker run -p 1358:1358 -d appbaseio/dejavu
open http://localhost:1358/live
You can also run a specific version of dejavu by specifying a tag. For example, version 1.0.0 can be used by specifying the docker run -p 1358:1358 appbaseio/dejavu:1.0.0 command.
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://localhost:1358"
http.cors.enabled: true
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization
http.cors.allow-credentials: trueIf you are running your Elasticsearch with docker, you can use flags to pass the custom CORS configuration.
docker run --name es -d -p 9200:9200 elasticsearch:2 -Des.http.port=9200 -Des.http.cors.allow-origin="http://localhost:1358" -Des.http.cors.enabled=true -Des.http.cors.allow-headers=X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization -Des.http.cors.allow-credentials=true
docker run --name es -d -p 9200:9200 -d elasticsearch:5 -E http.port=9200 -E http.cors.allow-origin="http://localhost:1358" -E http.cors.enabled=true -E http.cors.allow-headers=X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization -E http.cors.allow-credentials=true
can also be run via hosted app at https://opensource.appbase.io/dejavu/live or installed as a chrome extension.
For example: If you are using the chrome-extension instead of docker image, the http.cors.allow-origin in Elasticsearch.yml file would change accordingly:
http.port: 9200
http.cors.allow-origin: "chrome-extension://jopjeaiilkcibeohjdmejhoifenbnmlh"
http.cors.enabled: true
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type,Content-Length,Authorization
http.cors.allow-credentials: true
