A tiny command line tool to upload a file to AWS S3

S3.js

// yarn add s3
const s3 = require('s3');

const helpPrases = ['help', '?', '-help', '--help'];

if (!process.argv[2] || helpPrases.includes(process.argv[2])) {
  console.log(`USEAGE: node s3.js <path to file> <bucket name> <destination name>`);
  return;
}

const client = s3.createClient({
  maxAsyncS3: 20,
  s3RetryCount: 3,
  s3RetryDelay: 1000,
  multipartUploadThreshold: 20971520,
  multipartUploadSize: 15728640,
  s3Options: {
    accessKeyId: process.env.AWS_ID,
    secretAccessKey: process.env.AWS_SECRET
  },
});

const uploadParams = {
  localFile: `${__dirname}/${process.argv[2]}`,
  s3Params: {
    Bucket: process.argv[3],
    Key: process.argv[4]
  }
}

const uploader = client.uploadFile(uploadParams);

uploader.on('error', err => console.error("unable to upload:", err.stack));

uploader.on('progress', () => console.log("progress", uploader.progressMd5Amount, uploader.progressAmount, uploader.progressTotal));

uploader.on('end', () => console.log("done uploading"));
