We first did a Show HN ~1.5 years ago; this is a super major overhaul with active development since and close to 100 issue fixes.<p>Direct link to try it out - <a href="https://opensource.appbase.io/dejavu/" rel="nofollow">https://opensource.appbase.io/dejavu/</a>.<p>* The biggest change today is the ability to import data into Elasticsearch directly via JSON and CSV files. Their is a guided process for setting the mappings correctly.<p>* Filtered views and query views.<p>* Ability to export filtered data as JSON / CSV, apparently other web UIs don't support this.<p>* There is also a docker image option to run it as Elasticsearch removed website plugins starting v5.0.<p>We originally wrote it in React v0.14.0 and have made it compatible with the React v15.6. There is an ongoing refactoring effort to translate all the code to use ES6 idioms.<p>Would like to hear what improvements can be made, I am not perfectly happy with how we are supporting mappings in the import process.
