dsh-mime

In everyday development—whether configuring Content-Type headers, handling file uploads, or processing email attachments—you often need to quickly confirm which MIME type maps to a given file extension. dsh-mime exists for exactly this: it bundles a complete MIME type table into a pure Node.js plugin, so a single call returns the answer with zero network requests and no external service dependency.

This means the plugin works entirely offline. Inside a corporate intranet, a CI pipeline, or any network-restricted environment, you can still get accurate type/subtype values in milliseconds—no third-party API quota, no DNS resolution, no timeout risk. Everything runs in-process on your local Node runtime.

Who is it for? Any front-end, back-end, or full-stack developer who frequently needs to look up MIME mappings while coding, especially in workflows where network isolation is a hard requirement or where response latency matters. Once installed, simply invoke the registered tool in your session—no extra configuration needed.
