MinIO JavaScript Library for Amazon S3 Compatible Cloud Storage
The MinIO JavaScript Client SDK provides high level APIs to access any Amazon S3 compatible object storage server.
This 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 presumes you have a working Node.js development environment, LTS versions v16, v18 or v20.
Download from NPM
npm install --save minio
Download from Source
git clone https://github.com/minio/minio-js
cd minio-js
npm install
npm run build
npm install -g
Using with TypeScript
minio>7.1.0
is shipped with builtin type definition, @types/minio
is no longer needed.
Initialize MinIO Client
The following parameters are needed to connect to a MinIO object storage server:
Parameter | Description |
---|
endPoint | Hostname of the object storage service. |
port | TCP/IP port number. Optional, defaults to 80 for HTTP and 443 for HTTPs. |
accessKey | Access key (user ID) of an account in the S3 service. |
secretKey | Secret key (password) of an account in the S3 service. |
useSSL | Optional, set to 'true' to enable secure (HTTPS) access. |
import * as Minio from 'minio'
const minioClient = new Minio.Client({
endPoint: 'play.min.io',
port: 9000,
useSSL: true,
accessKey: 'Q3AM3UQ867SPQQA43P2F',
secretKey: 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG',
})
Quick Start Example - File Uploader
This example connects to an object storage server, creates a bucket, and uploads a file to the bucket.
It uses the MinIO play
server, a public MinIO cluster located at https://play.min.io.
The play
server runs the latest stable version of MinIO and may be used for testing and development.
The access credentials shown in this example are open to the public.
All data uploaded to play
should be considered public and non-protected.
file-uploader.mjs
import * as Minio from 'minio'
const minioClient = new Minio.Client({
endPoint: 'play.min.io',
port: 9000,
useSSL: true,
accessKey: 'Q3AM3UQ867SPQQA43P2F',
secretKey: 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG',
})
const sourceFile = '/tmp/test-file.txt'
const bucket = 'js-test-bucket'
const destinationObject = 'my-test-file.txt'
const exists = await minioClient.bucketExists(bucket)
if (exists) {
console.log('Bucket ' + bucket + ' exists.')
} else {
await minioClient.makeBucket(bucket, 'us-east-1')
console.log('Bucket ' + bucket + ' created in "us-east-1".')
}
var metaData = {
'Content-Type': 'text/plain',
'X-Amz-Meta-Testing': 1234,
example: 5678,
}
await minioClient.fPutObject(bucket, destinationObject, sourceFile, metaData)
console.log('File ' + sourceFile + ' uploaded as object ' + destinationObject + ' in bucket ' + bucket)
Run the File Uploader
node file-uploader.mjs
Bucket js-test-bucket created successfully in "us-east-1".
File /tmp/test-file.txt uploaded successfully as my-test-file.txt to bucket js-test-bucket
Verify the object was created with mc
:
mc ls play/js-test-bucket
[2023-11-10 17:52:20 UTC] 20KiB STANDARD my-test-file.txt
