You can upload files on AWS S3 using a\u00a0server side solution, but in case of larger files it is advisable to use a\u00a0client side solution. You can probably\u00a0use\u00a0JavaScript<\/a> file upload feature of AWS S3.\u00a0This is simple three step feature as described below:<\/p>\n

Step 1 : In the head section of your page include javascript sdk and specify your keys like this:<\/p>\n

[code]
\n<script src="https:\/\/sdk.amazonaws.com\/js\/aws-sdk-2.1.24.min.js"><\/script>
\n<script type="text\/javascript">
\n AWS.config.update({
\n accessKeyId : ‘ACCESS_KEY’,
\n secretAccessKey : ‘SECRET_KEY’
\n });
\n AWS.config.region = ‘AWS_REGION’;
\n<\/script>
\n[\/code]<\/p>\n

Step 2\u00a0: Now create a simple html form with a file input.<\/p>\n

[code]
\n<form id="fileUploadForm" method="post" enctype="multipart\/form-data">
\n<input type="file" name="file" id="file" value="dataFile" required="">
\n<\/form>
\n[\/code]<\/p>\n

Step 3\u00a0: Now upload your\u00a0input file to S3<\/p>\n

[code]
\n$("#fileUploadForm").submit(function() {
\nvar bucket = new AWS.S3({params: {Bucket: ‘BUCKET_NAME’}});
\nvar fileChooser = document.getElementById(‘file’);
\nvar file = fileChooser.files[0];
\nif (file) {
\nvar params = {Key: ‘FILE_NAME’, ContentType: file.type, Body: file};
\nbucket.upload(params).on(‘httpUploadProgress’, function(evt) {
\nconsole.log("Uploaded :: " + parseInt((evt.loaded * 100) \/ evt.total)+’%’);
\n}).send(function(err, data) {
\nalert("File uploaded successfully.");
\n});
\n}
\nreturn false;
\n});
\n[\/code]<\/p>\n

To upload the file successfully, you need to enable CORS configuration on S3.<\/p>\n

Generally, it is not advisable to display your keys directly on page, so you can use Amazon Cognito or web identity federation feature.<\/p>\n
