How to use AWS SDK for Javascript with MinIO Server

In this recipe we will learn how to use aws-sdk for Javascript with MinIO server. aws-sdk is the official AWS SDK for the Javascript programming language.

1. Prerequisites

Install MinIO Server from here.

2. Installation

Install aws-sdk for Javascript from the official AWS Javascript SDK docs here

3. Example

Replace endpoint,accessKeyId, secretAccessKey, Bucket and Object with your local setup in this example.js file.

The example below shows putObject and getObject operations on MinIO server using aws-sdk.

var AWS = require('aws-sdk');

var s3  = new AWS.S3({
          accessKeyId: 'YOUR-ACCESSKEYID' ,
          secretAccessKey: 'YOUR-SECRETACCESSKEY' ,
          endpoint: 'http://127.0.0.1:9000' ,
          s3ForcePathStyle: true, // needed with minio?
          signatureVersion: 'v4'
});

// putObject operation.

var params = {Bucket: 'testbucket', Key: 'testobject', Body: 'Hello from MinIO!!'};

s3.putObject(params, function(err, data) {
      if (err)
       console.log(err)
      else   
       console.log("Successfully uploaded data to testbucket/testobject");
});

// getObject operation.

var params = {Bucket: 'testbucket', Key: 'testobject'};

var file = require('fs').createWriteStream('/tmp/mykey');

s3.getObject(params).
on('httpData', function(chunk) { file.write(chunk); }).
on('httpDone', function() { file.end(); }).
send();

4. Run the Program
