I upgraded a npm and now my webpack fails around this line here.
const { theme } = params;
What does this mean when you have { } around the variable name?

This is called destructuring assignment. The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.
