Delivering script files directly from the karma server

I am currently conducting tests on phantomjs using the karma runner, and I have encountered a problem where my ajax calls are consistently failing with a 404 error.

After some struggle in determining the correct placement of the file (refer to: Including libraries fails - what is document root?), I stumbled upon a post (Loading external file from Karma/Jasmine test) that suggests configuring the karma web server to serve additional files.

Specifically, the ajax calls are attempting to access files from the node_modules directory, so I have adjusted the karma.config.js as follows:

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

Despite this configuration, my ajax calls still fail. Here is an example of how my ajax calls are structured (I have created a blah.js file in the directory for testing):

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

What could be causing this issue to persist? Any insights would be greatly appreciated.

Answer №1

It may seem strange, but the karma documentation states:

By default, all assets are served at

So, to make it work: 1) Add this code to your karma.conf.js:

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

2) Use the following AJAX call:

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

This raises the question of how to configure that base, but for now, this method works.
