[geetee24]

need example of using s3fs and stream to download s3 file to local file of any size please.

[hasnat]

here's a dirty example;

const S3FS = require('@hasnat/s3fs');
const pathName = '/s3/file/path/key';
const downloadFilePath = '/tmp/file-downloaded-from-s3';
const bucket = 's3-bucket-name';
const s3fs = new S3FS(bucket,{
        accessKeyId: 'xxx',
        secretAccessKey: 'xxxxx',
       region: 'us-east-1'
    });
const s3Options = {}; //e.g. s3Options.Range =  'bytes=1234'
const s3Stream = s3fs.createReadStream(pathName,{s3Options});

s3Stream.on('error',console.error)
outputStream = fs.createWriteStream(downloadFilePath);

s3Stream.pipe(outputStream)
            .on('close', function () {
                outputStream.end();
                console.log('file save complete');
            });
