How to unzip .zip files from s3 bucket back to s3

#s3 #aws #node #typescript

The problem

Get an .zip file provided from s3 bucket and upload the extracted folder and its content back to s3 bucket

The solution

Built an npm package that gets an .zip file from s3 and create streams, with that you can do whatever you want with the extracted content.
You can check more and contribute to our package in: s3-zip-handler

built-in possibilities

Send extracted folder back to s3 bucket


import AWS from 'aws-sdk'
import s3ZipHandler, { IS3ZipFileParams } from 's3-zip-handler'

const s3Client = new AWS.S3({
...your s3 settings
})


const s3Config: IS3ZipFileParams = {
    s3Client,
    bucket: 'your-s3-bucket',
    key: 'your-s3-key/your-zip-file.zip',
    params: {
      ACL: 'public-read',
      ContentDisposition: 'inline'
    }
} 

const {
localPath, 
uploadedPath 
} = await s3ZipHandler.decompressToKeyFolderS3(s3Config)

// localPath = 'os-tmp/unzipped-xxxx/your-zip-file'
// uploadedPath  = 'your-s3-bucket/your-s3-key/your-zip-file'

Manipulate locally the extracted folder

import s3ZipHandler from 's3-zip-handler'
import AWS from 'aws-sdk'

const s3Client = new AWS.S3({
    ...your s3 settings
})

const s3Config = {
    s3Client,
    bucket: 'your-s3-bucket',
    key: 'your-s3-key/your-zip-file.zip'
} 

const {
 localPath
 } = await s3ZipHandler.decompressLocal(s3Config, 'path-to-extract')

// localPath = 'path-to-extract/your-zip-file'
