You can do this by AWS S3 Cognito try this link here :
http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/browser-examples.html#Amazon_S3
Also try this code
Just change Region, IdentityPoolId and Your bucket name
<!DOCTYPE html>
<html>
<head>
<title>AWS S3 File Upload</title>
<script src="https://sdk.amazonaws.com/js/aws-sdk-2.1.12.min.js"></script>
</head>
<body>
<input type="file" id="file-chooser" />
<button id="upload-button">Upload to S3</button>
<div id="results"></div>
<script type="text/javascript">
AWS.config.region = 'your-region'; // 1. Enter your region
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
IdentityPoolId: 'your-IdentityPoolId' // 2. Enter your identity pool
});
AWS.config.credentials.get(function(err) {
if (err) alert(err);
console.log(AWS.config.credentials);
});
var bucketName = 'your-bucket'; // Enter your bucket name
var bucket = new AWS.S3({
params: {
Bucket: bucketName
}
});
var fileChooser = document.getElementById('file-chooser');
var button = document.getElementById('upload-button');
var results = document.getElementById('results');
button.addEventListener('click', function() {
var file = fileChooser.files[0];
if (file) {
results.innerHTML = '';
var objKey = 'testing/' + file.name;
var params = {
Key: objKey,
ContentType: file.type,
Body: file,
ACL: 'public-read'
};
bucket.putObject(params, function(err, data) {
if (err) {
results.innerHTML = 'ERROR: ' + err;
} else {
listObjs(); // this function will list all the files which has been uploaded
//here you can also add your code to update your database(MySQL, firebase whatever you are using)
}
});
} else {
results.innerHTML = 'Nothing to upload.';
}
}, false);
function listObjs() {
var prefix = 'testing';
bucket.listObjects({
Prefix: prefix
}, function(err, data) {
if (err) {
results.innerHTML = 'ERROR: ' + err;
} else {
var objKeys = "";
data.Contents.forEach(function(obj) {
objKeys += obj.Key + "<br>";
});
results.innerHTML = objKeys;
}
});
}
</script>
</body>
</html>
I hope it will help others :)

Firebase engineer:
I'd recommend using our newest product, Firebase Storage , which is a Firebase wrapper around Google Cloud Storage to provide secure, resumable uploads and downloads, directly from mobile clients--it basically replaces this with a Firebase Database integrated solution! We've also got a generous free tier and competitive pricing after that, and an API that is also directly compatible with S3 (through Google Cloud Storage).
