Interacting with CouchDB using AJAX

Currently, I am creating a sample project using CouchDB. My plan is to develop a web application with AJAX and host it in the tomcat environment. I am interested in learning how to effectively communicate with the CouchDB server. While researching, I came across some examples but I have a few concerns.

1) Given that my application will be hosted on a web server, is it possible to connect to a CouchDB instance externally? Many examples seem to focus on applications deployed in CouchApp or Couch environments.

2) If connecting externally is feasible, will this lead to cross-domain issues? I came across a discussion regarding this topic at Connection AJAX, CouchDB and JavaScript.

3) To avoid the aforementioned problems, would utilizing a server-side JavaScript implementation such as Rhino be a viable solution? More information on Rhino can be found at .

4) If Rhino restricts the use of many JavaScript libraries, how can I effectively interact with CouchDB? Will I need to rely solely on native JavaScript or could a library like jQuery be utilized?

5) What are some recommended client-side libraries for achieving my objectives?

I would greatly appreciate any assistance you can provide. Thank you.

Answer №1

If you find yourself needing to utilize Tomcat, my recommendation would be to consider using Ektorp (http://ektorp.org/). Think of Ektorp as a JDBC driver - there's no need for AJAX from the user interface or utilizing JavaScript from Java on your server.

Ektorp also allows you to annotate your Java classes with the necessary JavaScript for CouchDB to create views. You can check out an example here:

I hope this information is helpful to you.
