MinIO JavaScript Library for Amazon S3 Compatible Cloud Storage

The MinIO JavaScript Client SDK provides simple APIs to access any Amazon S3 compatible object storage server.

This quickstart guide will show you how to install the client SDK and execute an example JavaScript program. For a complete list of APIs and examples, please take a look at the JavaScript Client API Reference documentation.

This document assumes that you have a working nodejs setup in place.

Download from NPM

npm install --save minio

Download from Source

git clone https://github.com/minio/minio-js
cd minio-js
npm install
npm install -g

Using with TypeScript

npm install --save-dev @types/minio

Initialize MinIO Client

You need five items in order to connect to MinIO object storage server.

Params	Description
endPoint	URL to object storage service.
port	TCP/IP port number. This input is optional. Default value set to 80 for HTTP and 443 for HTTPs.
accessKey	Access key is like user ID that uniquely identifies your account.
secretKey	Secret key is the password to your account.
useSSL	Set this value to 'true' to enable secure (HTTPS) access

var Minio = require('minio')

var minioClient = new Minio.Client({
    endPoint: 'play.min.io',
    port: 9000,
    useSSL: true,
    accessKey: 'Q3AM3UQ867SPQQA43P2F',
    secretKey: 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG'
});

Quick Start Example - File Uploader

This example program connects to an object storage server, makes a bucket on the server and then uploads a file to the bucket.

We will use the MinIO server running at https://play.min.io in this example. Feel free to use this service for testing and development. Access credentials shown in this example are open to the public.

file-uploader.js

var Minio = require('minio')

// Instantiate the minio client with the endpoint
// and access keys as shown below.
var minioClient = new Minio.Client({
    endPoint: 'play.min.io',
    port: 9000,
    useSSL: true,
    accessKey: 'Q3AM3UQ867SPQQA43P2F',
    secretKey: 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG'
});

// File that needs to be uploaded.
var file = '/tmp/photos-europe.tar'

// Make a bucket called europetrip.
minioClient.makeBucket('europetrip', 'us-east-1', function(err) {
    if (err) return console.log(err)

    console.log('Bucket created successfully in "us-east-1".')

    var metaData = {
        'Content-Type': 'application/octet-stream',
        'X-Amz-Meta-Testing': 1234,
        'example': 5678
    }
    // Using fPutObject API upload your file to the bucket europetrip.
    minioClient.fPutObject('europetrip', 'photos-europe.tar', file, metaData, function(err, etag) {
      if (err) return console.log(err)
      console.log('File uploaded successfully.')
    });
});

Run file-uploader

node file-uploader.js
Bucket created successfully in "us-east-1".

mc ls play/europetrip/
