How to upload files to AWS S3 with NodeJS SDK

AWS_S3_File_Upload.js

var AWS = require('aws-sdk'),
    fs = require('fs');

// For dev purposes only
AWS.config.update({ accessKeyId: '...', secretAccessKey: '...' });

// Read in the file, convert it to base64, store to S3
fs.readFile('del.txt', function (err, data) {
  if (err) { throw err; }

  var base64data = new Buffer(data, 'binary');

  var s3 = new AWS.S3();
  s3.client.putObject({
    Bucket: 'banners-adxs',
    Key: 'del2.txt',
    Body: base64data,
    ACL: 'public-read'
  },function (resp) {
    console.log(arguments);
    console.log('Successfully uploaded package.');
  });

});

Hi team,
download pdf file from website , zip those pdf files and upload those zip file S3 bucket.
some one help me on that issue.
using Lambda function with node.js

it works for me :)

uploadContentFromFilePath = (fileName) => {
const fileContent = fs.createReadStream(${fileName});
return new Promise(function (resolve, reject) {
fileContent.once('error', reject);
s3.upload(
{
Bucket: 'test-bucket',
Key: ${fileName + '_' + Date.now().toString()},
ContentType: 'application/pdf',
ACL: 'public-read',
Body: fileContent
},
function (err, result) {
if (err) {
reject(err);
return;
}
resolve(result.Location);
}
);
});
}

if u get error 'putObject is not defined' , you can write like this ,

var s3 = new AWS.S3();

s3.putObject({
Bucket: 'xxx',
Key: 'xxx',
Body: 'what you want to upload',
},function () {
console.log('Successfully uploaded package.');
});

Thank you, everybody, for your comments 🙌

@coolaj86 Thank you for your snippet, I just wonder how to use it with an input file form?

Thanks

By far the best simple and straightforward code/implementation and brief explanation I've found. Been stuck on this for 2-3 days lol Thanks guys - peace and love
