About

@ntegral/nestjs-s3 implements a module, S3Module, which when imported into your nestjs project provides an S3 client to any class that injects it. This lets AWS S3 be worked into your dependency injection workflow without having to do any extra work outside of the initial setup.

Installation

npm install --save @ntegral/nestjs-s3 aws-sdk

Getting Started

The simplest way to use @ntegral/nestjs-s3 is to use S3Module.forRoot

import { Module } from '@nestjs-common';
import { S3Module } from '@ntegral/nestjs-s3';

@Module({
  imports: [
    S3Module.forRoot({
      accessKeyId: 'aws_access_key_id',
      secretAccessKey: 'aws_secret_access_key',
      region?: 'aws_region_id',
      sessionToken?: 'aws_session_token', | null, 
      apiVersion?: 's3_api_version' //based on s3 api version //
    }),
  ],
})
export class AppModule {}

The async way @ntegral/nestjs-s3 is to use S3Module.forRootAsync

import { Module } from '@nestjs-common';
import { S3Module } from '@ntegral/nestjs-s3';
import { ConfigModule } from '@ntegral/nestjs-config';
import { ConfigService } from '@ntegral/nestjs-config';

@Module({
  imports: [
    S3Module.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (cfg:ConfigService) => ({
        accessKeyId: cfg.get('ACCESS_KEY_ID'),
        secretAccessKey: 'AWS_SECRET_ACCESS_KEY'
      }),
      inject: [ConfigService],
    })
  ]
})

export class AppModule {}

You can then inject the S3 client into any of your injectables by using a custom decorator

import { Injectable } from '@nestjs/common';
import { InjectS3 } from '@ntegral/nestjs-s3';
import * as S3 from 'aws-sdk/clients/s3';

@Injectable()
export class AppService {
  public constructor(@InjectS3() private readonly client: S3) { }

  upload(pdf) {
        const params = {
        ACL: 'public-read',
        Body: pdf,
        Bucket: process.env.BUCKET,
        Key: uuidv4(),
        ContentEncoding: 'base64',
        ContentType: `application/pdf`
    };
    try {
        const { Location, Key } = await this.client.upload(params).promise();
        return Location;
    } catch (error) {
        console.log('ERROR S3 FILE UPLOAD => ', error);
    }
  }
}
