node.js renaming s3 object via aws-sdk module - node.js

Question

Is it possible to rename an object on s3 via aws-sdk? I couldn't find a method for that, maybe there is a provisionary solution ...

Answer 1

I will answer I guess since no one has - this one should work
// create a new s3 object
var s3 = new AWS.S3();
var BUCKET_NAME = 'your-bucket-name';
var OLD_KEY = '/original-file.js';
var NEW_KEY = '/new-file.js';
// Copy the object to a new location
s3.copyObject({
Bucket: BUCKET_NAME,
CopySource: `${BUCKET_NAME}${OLD_KEY}`,
Key: NEW_KEY
})
.promise()
.then(() =>
// Delete the old object
s3.deleteObject({
Bucket: BUCKET_NAME,
Key: OLD_KEY
}).promise()
)
// Error handling is left up to reader
.catch((e) => console.error(e))

This is just a flow on from #nf071590 answer. Which is awesome.
Below, gets the entire list of a bucket and then changes the image name of every image that isn't .jpg to .jpg
Hope this helps someone. :)
const start = new Date()
const AWS = require('aws-sdk')
const state = {}
AWS.config.update({ region: 'ADD_REGION_HERE' })
try {
var s3 = new AWS.S3();
var BUCKET_NAME = 'ADD_BUCKET_NAME_HERE';
var params = {
Bucket: BUCKET_NAME,
MaxKeys: 1000
};
s3.listObjects(params, function (err, data) {
if (err) {
console.log(err, err.stack); // an error occurred
} else {
console.log(data);
data.Contents.forEach(image => {
var OLD_KEY = image.Key
var NEW_KEY = ''
// split key
var keyArray = image.Key.split('.')
var keyArrayLength = keyArray.length
console.log(keyArrayLength);
var ext = keyArray[keyArrayLength - 1]
// console.log(ext);
if(ext != 'jpg') {
console.log('Change this ext FROM: ', OLD_KEY)
ext = 'jpg'
if (keyArrayLength == 2) {
NEW_KEY = `${keyArray[0]}.${ext}`
} else if (keyArrayLength == 3) {
NEW_KEY = `${keyArray[0]}.${keyArray[1]}.${ext}`
} else if (keyArrayLength == 4) {
NEW_KEY = `${keyArray[0]}.${keyArray[1]}.${keyArray[2]}.${ext}`
}
console.log('TO:: ', NEW_KEY);
// Copy the object to a new location
try {
s3.copyObject({
Bucket: BUCKET_NAME,
CopySource: `${BUCKET_NAME}/${OLD_KEY}`,
Key: NEW_KEY
}).promise()
.then((response) => {
console.log('Seemed to have worked??');
console.log(response);
// Delete the old object
s3.deleteObject({
Bucket: BUCKET_NAME,
Key: OLD_KEY
}).promise()
})
// Error handling is left up to reader
.catch((e) => console.error(e))
} catch (error) {
console.log('error::', error);
}
}
});
}
});
} catch (err) {
const end = new Date() - start
let seconds = end / 1000
state.seconds = seconds
state.error = err
state.status = "error"
state.message = err.message
console.log(err)
console.log(state);
return
}
