Minio Module for Nest framework

Description

This's a nest-minio module for Nest. 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.

Installation

1$ npm i --save nestjs-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

Provide the credentials for minio module by importing it as :

1import { Module } from '@nestjs/common';
2import { NestMinioClientController } from './nest-minio-client.controller';
3import { NestMinioModule } from '../nest-minio.module';
4
5@Module({
6  controllers: [NestMinioClientController],
7  imports: [
8    NestMinioModule.register(
9      isGlobal: true,
10      {
11      endPoint: 'play.min.io',
12      port: 9000,
13      useSSL: true,
14      accessKey: 'Q3AM3UQ867SPQQA43P2F',
15      secretKey: 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG',
16    }),
17  ],
18})
19export class NestMinioClientModule {}
20

Then you can use it in the controller or service by injecting it in the controller as:

1
2 constructor(@Inject(MINIO_CONNECTION) private readonly minioClient) {}
3

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.

1
2import { Controller, Get, Inject } from '@nestjs/common';
3import { MINIO_CONNECTION } from '../constants';
4import {Client, InjectMinio} from 'minio';
5
6@Controller()
7export class NestMinioClientController {
8 // use inject token
9  constructor(@Inject(MINIO_CONNECTION) private readonly minioClient: Client) {}
10
11  // or use inject decorator
12  // constructor(@InjectMinio() private readonly minioClient: Client) {}
13
14  @Get()
15  index() {
16    const file = '/tmp/app.zip';
17
18    const metaData = {
19      'Content-Type': 'application/octet-stream',
20      'X-Amz-Meta-Testing': 1234,
21      example: 5678,
22    };
23    // Using fPutObject API upload your file to the bucket europetrip.
24    this.minioClient.fPutObject(
25      'europetripxxx3',
26      'app.zip',
27      file,
28      metaData,
29      function(err, etag) {
30        if (err) {
31          return console.log(err);
32        }
33        console.log('File uploaded successfully.');
34      },
35    );
36  }
37}
