After the completion of Sealights scanning and/or instrumentation command, the source map files are not required anymore from Sealights' point of view. In order to avoid publishing those files in your production environments and/or optimize the size of the deployed folder, you can delete them.
For example, you can use the following command to find and delete all the files before packing and deploying:
Linux:
find . -name "*.js.map" -exec rm {} \;Windows command prompt:
del /s **\*dist\*.js.map
