How to receive an uploaded file using node.js formidable library and save it to Amazon S3 using knox?

It looks like there is no good way to do it. One reason might be that the node-formidable library saves the uploaded file to disk. I could not find any options to do otherwise.

The knox library takes the saved file on the disk and using your Amazon S3 credentials uploads it to Amazon Since on Heroku I cannot save files locally, I ended up using transloadit service. Though their authentication docs have some learning curve, I found the service useful For those who want to use transloadit using node. Js, the following code sample may help (transloadit page had only Ruby and PHP examples) var crypto, signature; crypto = require('crypto'); signature = crypto.

CreateHmac("sha1", 'auth secret'). Update('some string'). Digest("hex") console.

Log(signature).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
