By removing sourceMaps, the size of @fastify/swagger-ui package is reduced by ~2.7MB.
This PR modifies prepare-swagger-ui.js to not bundle .map files, but also removes the source map annotation from the source files so browsers do not attempt to retrieve the sourceMaps.
Please see the Source Map SPEC for the definition of the sourceMap annotations we are removing.
The annotation comments are slightly different for js/css, and I'm using a regex to handle both cases
Js://# sourceMappingURL=swagger-ui.js.map
css:/*# sourceMappingURL=swagger-ui.css.map*/
Build performance
I was worried searching/removing the annotations from the source files would be quite slow but there does not seem to be a performance impact.
