AWS S3 node.js SDK uploaded file and folder permissions

Question

I\'m uploading file to S3 using aws-sdk package:

fs.readFile(sourceFile, function (err, data) {
    if (err) { throw err; }

    s3.client.putObject({
        Bu         


        

Answer 1

Here is a working code snippet that uploads a local file (test-file.gif) to S3 bucket and prints out a URL for everyone to download.

const fs = require('fs');
const AWS = require('aws-sdk');
AWS.config.update({ region: 'us-west-1' });

// Fill in your bucket name and local file name:
const BUCKET_NAME = 'test-bucket-name-goes-here'
const FILE_NAME_LOCAL = './test-file.gif'
const FILE_NAME_S3 = 'this-will-be-the-file-name-on-s3.gif'
const FILE_PERMISSION = 'public-read'

// Create S3 service object
s3 = new AWS.S3({ apiVersion: '2006-03-01' });

// Get file stream
const fileStream = fs.createReadStream(FILE_NAME_LOCAL);

// Call S3 to retrieve upload file to specified bucket
const uploadParams = {
    Bucket: BUCKET_NAME,
    Key: FILE_NAME_S3,
    Body: fileStream,
    ACL: FILE_PERMISSION
};

s3.upload(uploadParams, function (err, data) {
    if (err) {
        console.log("Error", err);
    } if (data) {
        console.log("Upload Success", data.Location);
    }
});
