Serving script files from karma server

Question

I'm running tests on phantomjs via the karma runner and some of my code makes ajax calls which all fail with a 404.

I've struggled with where to place the file (see: Including libraries fails - what is document root?) but I came across a post (Loading external file from Karma/Jasmine test) that indicates I can configure the karma web server to serve other files.

in particular the ajax calls are attempting to load files from the node_modules directory so I've configured the karma.config.js like this:

files: [{
    pattern: 'node_modules/*',
    served: true,
    included: false
}]

and my ajax calls look generally like this (I've placed a blah.js in the directory for testing):

$.ajax({url: 'node_modules/blah.js', ...});

but still it doesn't work. what am I missing?

well... this is odd but according to the karma docs:

By default all assets are served at http://localhost:[PORT]/base/

so this works: 1) in the karma.conf.js:

files: [{
  pattern: 'node_modules/**',
  served: true,
  included: false
}]

and 2) the call:

$.ajax({url: '/base/node_modules/blah.js', ...});

...which leaves the question of how that base can be configured, but for now, this works.
