node.js - Convert file from base64 and send to some external service as binary file -

-

i send file node.js server base64 string, need send external service binary file. possible without saving file file system? i'm trying file on node.js side in way:

var filedata    = req.body.value,     filename    = req.body.id,     base64data  = filedata.replace(/^data:image\/jpeg;base64,/,"");  modules.fs.writefile(      filename,       base64data,       'base64',       function(err)       {          if (err)          {              console.log(err);          }          else          {              //read file file system , send external service           }      });

write buffer:

var buffer = new buffer(base64data, 'base64');
