How to bulk upload files to S3 using node script

// uploadTos3.js const fs = require('fs'); const readDir = require('recursive-readdir'); const path = require('path'); const AWS = require('aws-sdk'); const mime = require('mime-types'); AWS.config.update({ region: 'ap-south-1', accessKeyId: process.env.AWS_ACCESS_KEY_ID, secretAccessKey: process.env.SECRET_ACCESS_KEY, maxRetries: 3 }); const directoryPath = path.resolve(__dirname, './images'); const getDirectoryFilesRecursive = (dir, ignores = []) => { return new Promise((resolve, reject) => { readDir(dir, ignores, (err, files) => (err ? reject(err) : resolve(files))); }); }; const generateFileKey = fileName => { const S3objectPath = fileName.split('/images/')[1]; return `website-assets/${S3objectPath}`; }; const s3 = new AWS.S3(); const uploadToS3 = async () => { try { const fileArray = await getDirectoryFilesRecursive(directoryPath, [ 'BUILD_ID' ]); fileArray.map(file => { // Configuring parameters for S3 Object const S3params = { Bucket: 'public-read-bucket', Body: fs.createReadStream(file), Key: generateFileKey(file), ACL: 'public-read', ContentType: mime.lookup(file), ContentEncoding: 'utf-8', CacheControl: 'immutable,max-age=31536000,public' }; s3.upload(S3params, function(err, data) { if (err) { // Set the exit code while letting // the process exit gracefully. console.error(err); process.exitCode = 1; } else { console.log(`Assets uploaded to S3: `, data); } }); }); } catch (error) { console.error(error); } }; uploadToS3();
