Can I use a library to simplify saving Base64 images in Node.js, and which one would you recommend?

While not strictly necessary, libraries can provide utility functions that simplify the process and handle edge cases. A good option is the built-in `fs` module combined with a library like `mime-types` for determining file extensions. Alternatively, you could consider using image processing libraries like `jimp` if you need to perform additional image manipulation beyond just saving. However, for simple saving, the built-in `fs` module is generally sufficient and avoids unnecessary dependencies.
