Re: [basex-talk] Cross-Origin Resource Sharing ( CORS) not available in jetty version 8

Hi Rob,

I have used the restxq custom response feature [1] to create the CORS header. Maybe it would work in your case?

http:response <http:header name="Access-Control-Allow-Origin" value="*"/> ... For example see [2]

(of course Jetty 9 support would be great)

Hi Michael.

Thanx fort he extended reply. As you said: a lot of options. Since this is a new area to me, it is a little overwhelming.

Well, didn’t have any plans this weekend.

Since I use NodeJS only for serving and generating Angular0files, I’ll start checking that one out.

Let you guys know when I’ve succeeded.

Thnx,

Rob

Hi Rob,

in addition to Christian’s mail, one more thought:

Great, angular2, haven’t had more than a brief look at it so far :-)

I guess you are using that NodeJS-application to serve and generate your AngularJS-files, right? Or are there any other reasons you need NodeJS for?

If you only need to serve your static files, you may as well use BaseX to serve static contents and put all (e.g. symlink) Angular related stuff to your `webapp/static`-folder.

The documentation is here: http://docs.basex.org/wiki/Web_Application# Available_Services

An example can be found here (https://github.com/BaseXdb/ basex/tree/master/basex-api/src/main/webapp) , there is a static folder that will be mapped to localhost:8984/restxq/static

If by any means you need the NodeJS Server next to RestXQ a possible solution might be proxying the requests from NodeJS to your BaseX instance; so from the Browsers perspective all requests are sent to localhost:3000 :-)

I used https://www.npmjs.com/package/express-http-proxy to redirect all request to http://localhost:3000/restxq -> http://localhost:8989/restxq/

If you can not modify your NodeJS-service you might have a look at https://github.com/gr2m/CORS-Proxy: it provides out-of-the-box CORS headers for arbitrary URLs

Lots of options for these OPTIONS headers ;-)

Hope this helps a bit.

P.S. in production it’s usually beneficial to have only a single web-server face the world

Hi Christian,

I’m trying to build a web based frontend with Angular(2) with Basex as backend.

Since Angular uses localhost:3000 and basex uses localhost:8984 I need CORS to be activated in the bachend’s jetty-service.

If I try to activate this by editing the web.xml file I get the message from the jetty that this service is not available.

Obviously version 8 of jetty does not support CORS. According to the documentation Jetty 9 should support CORS.

Is replacing jett 8 with version 9 somewere on the agenda? Or can I do this myself? (new area for me)

I wouldn’t mind testrunning it.

TIA,

Rob Stapper

PS. I see the request the request being handled and send back by the backend (basex) but it misses the necessary header. Debugging my Angular app in the browser say that CORS-header is missing.
