Sourcemaps bridge the gap between minified production code and readable source code, enabling effective debugging. They work by creating JSON mappings between transformed and original code, with options for inline, external, or hidden implementations. While essential in development, production sourcemaps require careful consideration—they improve error tracking and debugging but can expose code structure and internal logic. Best practices include restricting access via server configuration, using services like Sentry for private sourcemap uploads, and ensuring no sensitive data exists in client code. The choice depends on your security requirements and debugging needs.
