mime_type 0.1.2

MIME type library for Dart HTTP server applications.

MIME type

Library to get MIME type from a file name. When a HTTP server sends a file to the client, MIME type of the file must be set to the Content-Type header of the response.

Only two methods are availabe:

• String mime(String FileName) // gets MIME type from the file name (such as 'Hello.dar't)

• String mimeFromExtension(String extension) // gets MIME type from the extension (such as 'dart')

Both methods return null If MIME type for the file is not available.

Example

import 'package:mime_type/mime_type.dart';

sendFile(HttpRequest request, String fileName) {
  HttpResponse response = request.response;
  File file = new File(fileName);
  if (file.existsSync()) {
    String mimeType = mime(fileName);
    if (mimeType == null) mimeType = 'text/plain; charset=UTF-8';
      // you can change the default content type
      // or, you can choose to send error message
    response.headers.set('Content-Type', mimeType);
    RandomAccessFile openedFile = file.openSync();
    response.contentLength = openedFile.lengthSync();
    openedFile.closeSync();
    file.openRead().pipe(response);
  } else {
    // send 404 (Not Found) status to the client
  }
}
