aws | node.js | S3 file download

Hello,

Hope all are fine. This article is for writing a node script to download a file from s3 bucket.

Package needed

npm install aws-sdk

Package usage

const AWS = require('aws-sdk')

Code Example

        const filename = "test.pdf"
        const params = {
            Bucket: "mybucket",
            Key: `${filename}`,
        }

        // Retrieve the PDF file from S3
        s3.getObject(params, (err, data) => {
            if (err) {
                console.error(err)
                return res.status(500).send('Error retrieving file from S3')
            }

        //     // Set the appropriate headers for the response
            res.setHeader('Content-disposition', `attachment; filename=${filename}`)
            res.setHeader('Content-type', 'application/pdf')

            // Send the file content as the response
            res.send(data.Body)
        })

Hope its very simple and useful.
