Uploading base64 encoded Image to Amazon S3 via Node.js
Here's the code from one article I came across, posting below:
const imageUpload = async (base64) => {
const AWS = require('aws-sdk');
const { ACCESS_KEY_ID, SECRET_ACCESS_KEY, AWS_REGION, S3_BUCKET } = process.env;
AWS.config.setPromisesDependency(require('bluebird'));
AWS.config.update({ accessKeyId: ACCESS_KEY_ID, secretAccessKey: SECRET_ACCESS_KEY, region: AWS_REGION });
const s3 = new AWS.S3();
const base64Data = new Buffer.from(base64.replace(/^data:image\/\w+;base64,/, ""), 'base64');
const type = base64.split(';')[0].split('/')[1];
const userId = 1;
const params = {
Bucket: S3_BUCKET,
Key: `${userId}.${type}`, // type is not required
Body: base64Data,
ACL: 'public-read',
ContentEncoding: 'base64', // required
ContentType: `image/${type}` // required. Notice the back ticks
}
let location = '';
let key = '';
try {
const { Location, Key } = await s3.upload(params).promise();
location = Location;
key = Key;
} catch (error) {
}
console.log(location, key);
return location;
}
module.exports = imageUpload;

For people who are still struggling with this issue. Here is the approach I used with native aws-sdk :
var AWS = require('aws-sdk');
AWS.config.loadFromPath('./s3_config.json');
var s3Bucket = new AWS.S3( { params: {Bucket: 'myBucket'} } );
Inside your router method (ContentType
should be set to the content type of the image file):
var buf = Buffer.from(req.body.imageBinary.replace(/^data:image\/\w+;base64,/, ""),'base64')
var data = {
Key: req.body.userId,
Body: buf,
ContentEncoding: 'base64',
ContentType: 'image/jpeg'
};
s3Bucket.putObject(data, function(err, data){
if (err) {
console.log(err);
console.log('Error uploading data: ', data);
} else {
console.log('successfully uploaded the image!');
}
});
s3_config.json file :
{
"accessKeyId":"xxxxxxxxxxxxxxxx",
"secretAccessKey":"xxxxxxxxxxxxxx",
"region":"us-east-1"
}
