fix: node_modules sourceMaps

[m1ga]

Currently if you have npm modules that have source map files compiling will fail with:

[ERROR] TypeError [ERR_INVALID_ARG_TYPE]: The "paths[1]" argument must be of type string. Received undefined

The fix is to exclude files that are in the node_modules folder.

Test

• create a new app ti create --alloy
• create a app/lib folder
• go into that folder and install e.g. underscore using npm
• compile the app
