build
npx extension build [extension-path | extension-url] [options]Responsible for building the extension in production mode. Builds the extension for production, based on the browser choice. The build/ folder will include as many subfolders as the user browser choices. Each subfolder includes the code for that specific browser, with proper code transforms for each platform.
Users can also opt for a different port to run their extensions. Defaults to :8889.
