Hi, My front end is a browser-based javascript program that generates read- only queries. Should I have the js program communicating directly with elasticsearch? If not, is there any proxy/middleware setup you would recommend? Thanks. ---

I just started using ES too. I have a setup with a JS frontend directly communicating with ES. I'm using jQuery for JSONP and jQuery tmpl for templating. ES is fast, and returns a clean JSON file that you can dig out what you need with JS. I've had no problems communicating directly with ES, but it might depend on your environment and what you need to do with the results. ---

How did you solve security vulnerability issues?

There is a node.js proxy for elasticsearch: > **[GitHub - lukas-vlcek/node.es: Node gadgets for Elastic Search](https://github.com/lukas-vlcek/node.es)** > > Node gadgets for Elastic Search. Contribute to lukas-vlcek/node.es development by creating an account on GitHub. I was considering writing one for nginx, but I believe someone might already have done so. -- Ivan On Thu, Aug 18, 2011 at 4:33 AM, Andy [selforganized@gmail.com](mailto:selforganized@gmail.com) wrote: > Hi, > > My front end is a browser-based javascript program that generates read- > only queries.

Hi, note that this proxy hasn't been updated for a while but I think it probably still works fine in most cases (it is highly configurable). But generally speaking you should not directly expose ES api. It can be really dangerous. You should deploy proxy (and there are more option, not only node.js) Regards, Lukas On Thu, Aug 18, 2011 at 10:22 PM, Ivan Brusic [ivan@brusic.com](mailto:ivan@brusic.com) wrote: > There is a node.js proxy for elasticsearch: > [GitHub - lukas-vlcek/node.es: Node gadgets for Elastic Search](https://github.com/lukas-vlcek/node.es) > > I was considering writing one for nginx, but I believe someone might > already have done so. > > -- > Ivan > > On Thu, Aug 18, 2011 at 4:33 AM, Andy [selforganized@gmail.com](mailto:selforganized@gmail.com) wrote: > > > Hi, > > > > My front end is a browser-based javascript program that generates read- > > only queries.

It's running on a restricted network, so it's not really a problem. But for my next project, I could need a Python proxy for ES. Someone make. 😉 ---
