title: how can i download a video mp4 file using node.js?
body: <p>I want to let users download a video from my AWS S3 bucket. The video format is MP4:</p>
  
  <pre><code>app.get("/download_video", function(req,res) {
      filename = "s3.xxx.amazon.com/bucketname/folder/video_example.mp4";
      // im stuck on what i can do here
  });
  </code></pre>
  
  <p>There are a lot of examples on how to download images and textfiles online using nodejs, but I can't find anything on videos. </p>
