How to upload a file from the browser to Amazon S3 with node.js, Express, and knox? [closed]

Answer 1

* update *

as of mid 2009 amazon supports CORS and the upload via your node.js server isn't needed anymore. you can directly upload the file to S3.

---

with the help of the "connect-form" module you could just upload the file to your server (through normal multipart FORM) and then handle the S3 stuff afterwards ...

  
File

  
upload

node/express code:

app.post('/upload', function (req, res) {
  // connect-form additions
  req.form.complete(function (err, fields, files) {
    // here lies your uploaded file:
    var path = files['media']['path'];
    // do knox stuff here
  });
});

you have to add the following line to the app configuration:

app.configure(function(){
  // rest of the config stuff ...
  app.use(form({ keepExtensions: true }));
  // ...
});
