Mimex is a lightweight TypeScript/JavaScript utility for handling file extensions and MIME types. It provides an easy-to-use manager to look up MIME types from file extensions and vice versa, with full type safety when used in TypeScript projects.
Key features include:
- Retrieve one or multiple MIME types associated with a file extension.
- Retrieve all file extensions associated with a MIME type.
- Predefined, comprehensive list of common file extensions and MIME types.
- Fully typed for TypeScript with literal types for complete type safety.
- Exposes convenient readonly lists of all supported MIME types and extensions.
