How to disable CSS imports in JSPM / SystemJS

Question

My issue is JSPM / SystemJS manually inserting CSS dependencies (namely Angular Material's CSS) when I have a different pipeline for those (Gulp + SASS).

How can I tell JSPM to not import CSS files or interpret CSS dependencies in any way? I found only this discussion - https://github.com/jspm/jspm-cli/issues/791 - but it did not help me at all.

Answer 1

Seems that JSPM prefers local package overrides rather than turning off CSS features completely.

The culprit of my original issue is Angular Material's package.json, which contains the following JSPM configuration:

"shim": {
    "angular-material": {
        "deps": [ "./angular-material.css!" ]
      }
}

So what really solved my issue was to override that configuration:

jspm install angular-material -o '{ shim: {} }'
