I am at a loss of what I am doing wrong, here is what I have:
HTML
<html> <body> <form method="POST" action="/upload" enctype="multipart/form-data"> <div class="field"> <label for="image">Image Upload</label> <input type="file" name="image" id="image"> </div> <input type="submit" class="btn" value="Save"> </form> </body> </html> Port 5000 is my Node.js server's port.
In this example I am using POST to /upload, and it works fine.
module.exports = function(app, models) { var fs = require('fs'); var AWS = require('aws-sdk'); var accessKeyId = process.env.AWS_ACCESS_KEY || "xxxxxx"; var secretAccessKey = process.env.AWS_SECRET_KEY || "+xxxxxx+B+xxxxxxx"; AWS.config.update({ accessKeyId: accessKeyId, secretAccessKey: secretAccessKey }); var s3 = new AWS.S3(); app.post('/upload', function(req, res){ var params = { Bucket: 'makersquest', Key: 'myKey1234.png', Body: "Hello" }; s3.putObject(params, function (perr, pres) { if (perr) { console.log("Error uploading data: ", perr); } else { console.log("Successfully uploaded data to myBucket/myKey"); } }); }); } Now I want to post the file that I am POSTing, which is where the problem arises.
module.exports = function(app, models) { var fs = require('fs'); var AWS = require('aws-sdk'); var accessKeyId = process.env.AWS_ACCESS_KEY || "xxxxxx"; var secretAccessKey = process.env.AWS_SECRET_KEY || "+xxxxxx+B+xxxxxxx"; AWS.config.update({ accessKeyId: accessKeyId, secretAccessKey: secretAccessKey }); var s3 = new AWS.S3(); app.post('/upload', function(req, res){ var path = req.files.image.path; fs.readFile(path, function(err, file_buffer){ var params = { Bucket: 'makersquest', Key: 'myKey1234.png', Body: file_buffer }; s3.putObject(params, function (perr, pres) { if (perr) { console.log("Error uploading data: ", perr); } else { console.log("Successfully uploaded data to myBucket/myKey"); } }); }); }); } The error I get is:
TypeError: Cannot read property 'path' of undefined
As a matter of fact files is completely empty.
I am assuming I am missing something pretty obvious but I can't seem to find it.

Short description. When you upload large files to Amazon S3, it's a best practice to leverage multipart uploads. If you're using the AWS Command Line Interface (AWS CLI), then all high-level aws s3 commands automatically perform a multipart upload when the object is large.
You will need something like multer to handle multipart uploading. Here is an example streaming your file upload to s3 using aws-sdk.
var multer = require('multer'); var AWS = require('aws-sdk'); var accessKeyId = process.env.AWS_ACCESS_KEY || "xxxxxx"; var secretAccessKey = process.env.AWS_SECRET_KEY || "+xxxxxx+B+xxxxxxx"; AWS.config.update({ accessKeyId: accessKeyId, secretAccessKey: secretAccessKey }); var s3 = new AWS.S3(); app.use(multer({ // https://github.com/expressjs/multer dest: './public/uploads/', limits : { fileSize:100000 }, rename: function (fieldname, filename) { return filename.replace(/\W+/g, '-').toLowerCase(); }, onFileUploadData: function (file, data, req, res) { // file : { fieldname, originalname, name, encoding, mimetype, path, extension, size, truncated, buffer } var params = { Bucket: 'makersquest', Key: file.name, Body: data }; s3.putObject(params, function (perr, pres) { if (perr) { console.log("Error uploading data: ", perr); } else { console.log("Successfully uploaded data to myBucket/myKey"); } }); } })); app.post('/upload', function(req, res){ if(req.files.image !== undefined){ // `image` is the field name from your form res.redirect("/uploads"); // success }else{ res.send("error, no file chosen"); } }); If you love us?
