MIME Type Lookup

Node.jsHTTPFiles

Given a file path, return the MIME type based on extension.

Supported:

  • .html → 'text/html'
  • .css → 'text/css'
  • .js → 'application/javascript'
  • .json → 'application/json'
  • .png → 'image/png'
  • .jpg, .jpeg → 'image/jpeg'
  • Unknown / no ext → 'application/octet-stream'

Match is case-insensitive on the extension.
