Pixlet serve with query params

In the authoring tutorial, it says you can pass config variables with either

  1. Passing URL query parameters when using pixlet serve .
  2. Setting command-line arguments via pixlet render .

I was at least trying to do 1), but how do you pass query params with pixlet serve? I tried appending query params to http://127.0.0.1:8080 with no affect. It would be helpful if there were actual examples of each of these approaches.

run pixlet serve on a star file in the community repo. Then navigate to http://127.0.0.1:8080/
When you change the preference schemas they are added to the query params in the url. They should be accessible via the config object.
