I am uploading a file using NodeJS. My requirement is to read the stream into a variable so that I can store that into AWS SQS. I do not want to store the file on disk. Is this possible? I only need the uploaded file into stream. The code I am using is(upload.js):
var http = require('http');
var Busboy = require('busboy');
module.exports.UploadImage = function (req, res, next) {
var busboy = new Busboy({ headers: req.headers });
// Listen for event when Busboy finds a file to stream.
busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {
// We are streaming! Handle chunks
file.on('data', function (data) {
// Here we can act on the data chunks streamed.
});
// Completed streaming the file.
file.on('end', function (stream) {
//Here I need to get the stream to send to SQS
});
});
// Listen for event when Busboy finds a non-file field.
busboy.on('field', function (fieldname, val) {
// Do something with non-file field.
});
// Listen for event when Busboy is finished parsing the form.
busboy.on('finish', function () {
res.statusCode = 200;
res.end();
});
// Pipe the HTTP Request into Busboy.
req.pipe(busboy);
};
How do I get the uploaded stream?
On busboy 'file' event you get parameter named 'file' and this is a stream so you can pipe it.
For example
busboy.on('file', function (fieldname, file, filename, encoding, mimetype) {
file.pipe(streamToSQS)
}
