Package Exports

mimetype

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mimetype) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Overview

I find keep making these file extension lookup tables for mime types. It's about time I put it in a module to save me the trouble.

Example general case.

var mimetype = require('mimetype');

console.log(mimetype.lookup("myfile.txt")); // Should display text/plain
mimetype.set('.exotic', 'x-application/experimental'); // Add/update a mime type in the catalog
console.log(mimetype.lookup("myfile.exotic")); // Should display x-application/experimental
mimetype.del('.exotic'); // Removes the mime type from the catalog
console.log(mimetype.lookup("myfile.exitoc")); // Should display false
mimetype.forEach(function (ext, mime_type_string) {
  console.log(ext, mime_type_string); // Display the extension and matching mimetype in catalog
});

Special cases

Sometimes detecting by filename extensions isn't work and you want to default to a general purposes mime-type (e.g. text/plain, application/octet-stream).

var mimetype = require('mimetype');

// This should display 0 (false)
console.log(mimetype.lookup("filename.unknownMimeType");
// This should display the string text/plain
console.log(mimetype.lookup("filename.unknownMimeType", false, "text/plain");
// This should display the string text/plain; charset=UTF-8
console.log(mimetype.lookup("filename.unknownMimeType", "UTF-8", "text/plain");
