Add folder in Amazon s3 bucket

Question

I want to add Folder in my amazon s3 bucket using coding. Can you please suggest me how to achieve this?

Answer 1

Below creates a empty directory called "mydir1".

Below is nodejs code, it should be similar for other languages.

The trick is to have slash (/) at the end of the name of object, as in "mydir1/", otherwise a file with name "mydir1" will be created.

let AWS = require('aws-sdk');
AWS.config.loadFromPath(__dirname + '\\my-aws-config.json');
let s3 = new AWS.S3();

var params = {
    Bucket: "mybucket1",
    Key: "mydir1/",
    ServerSideEncryption: "AES256" };

s3.putObject(params, function (err, data) {
    if (err) {
        console.log(err, err.stack); // an error occurred
        return;
    } else {
        console.log(data);           // successful response
        return;
        /*
         data = {
         ETag: "\"6805f2cfc46c0f04559748bb039d69ae\"",
         ServerSideEncryption: "AES256",
         VersionId: "Ri.vC6qVlA4dEnjgRV4ZHsHoFIjqEMNt"
         }
         */
    } });
