Where does Polymer 2 CLI store variants?

Question

When you have a Polymer 2 bower.json with dependency variants and run polymer install --variants, where does it store the variant dependent components?

Answer 1

The variants are stored in the same parent directory of the default bower_components/. For example, given variants named "variant-1" and "variant-2", the resulting directory structure of the command is:

bower-variant-1.json
bower-variant-2.json
bower.json
bower_components/
bower_components-variant-1/
bower_components-variant-2/

You can find an example test fixture for the polymer install --variants command in polymer-cli source. Run the command in that directory to see the result described above.
