Express: Setting content-type based on path/file?

Question

I know Express has the res.contentType() method, but how to set automatically content type based on path/file (including static content)?

Answer 1

Run the following cmd :

npm install xmimetype ; 

Then , in your code :

  var xm=require("xmimetype");

  xm.mimetypeOf("java"); 
  xm.mimetypeOf("./lib/Person.java"); 
  // -> text/x-java-source

  xm.mimetypeOf("docx"); 
  xm.mimetypeOf("./lib/overview.docx"); 
  // -> application/vnd.openxmlformats-officedocument.wordprocessingml.document

For more info , check GIT repository .

The opposite is available :

  xm.extensionsOf("image/jpeg");
 // -> [ 'jpeg', 'jpg', 'jpe' ]
