Outputting other content types; besides HTML with Apps Script

Question

Is there a way to have a stand alone app output any other content-type besides HTML. i.e. if I wanted to output plain text so it could be consumed by another app (creating a simple web service)?

Answer 1

This week we launched the ContentService, which allows you to return content in formats such as JSON, ATOM, and plain text.

function doGet(e) {
  return ContentService.createTextOutput('Hello World')
      .setMimeType(ContentService.MimeType.TEXT);
}
