Usage

Importing module

import { S3Module, S3Service } from '@appotter/nestjs-s3';

@Module({
  imports: [
    S3Module.register({
      accessKeyId: 'Random key',
      secretAccessKey: 'Random secret',
      region: 'Region',
      bucket: 'Bucket name',
      acl: 'ACL', // optional, default is public-read
      endpoint: '', // optional
    }),
  ],
  providers: [S3Service],
  exports: [S3Service],
})
export class S3ProviderModule {}

Importing module Async

import { S3Module, S3Service } from '@appotter/nestjs-S3';
import { ConfigModule, ConfigService } from '@nestjs/config';

@Module({
  imports: [
    S3Module.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: (configService: ConfigService) => ({
        accessKeyId: configService.get('S3_ACCESS_KEY_ID'),
        secretAccessKey: configService.get('S3_SECRET_ACCESS_KEY'),
        region: configService.get('S3_REGION'),
        bucket: configService.get('S3_BUCKET'),
      }),
    }),
  ],
  providers: [S3Service],
  exports: [S3Service],
})
export class S3ProviderModule {}

Calling Method

import { S3Service, S3ModuleUploadedFile } from '@appotter/nestjs-S3';

@Injectable()
export class YourService {
  constructor(private s3Service: S3Service) {}

  async put(file: S3ModuleUploadedFile): Promise<void> {
    await this.s3Service.put(file, 'path-or-custom-file-name');
  }

  async putAsUniqueName(file: S3ModuleUploadedFile): Promise<void> {
    const { url } = await this.s3Service.putAsUniqueName(file);

    console.log(url);
    // https://bucket-name.s3.region.amazonaws.com/71d07956-26bb-4554-bb37-d00a7865ae29.png
  }

  async listAllFiles(): Promise<void> {
    const items = await this.s3Service.lists();

    console.log(items);
    // [
    //   {
    //     key: 'file.png',
    //     size: 123,
    //     lastModified: 2022-08-08T07:28:40.000Z,
    //     bucket: 'test',
    //   },
    //   {
    //     key: 'file2.png',
    //     size: 456,
    //     lastModified: 2022-08-08T07:45:46.000Z,
    //     bucket: 'test',
    //   },
    // ]
  }

  async getFile(file: string): Promise<void> {
    const item = await this.s3Service.get(file);

    console.log(item);
    // {
    //   key: 'file.jpg',
    //   contentLength: 123,
    //   contentType: 'application/octet-stream',
    //   body: '<Buffer ff d8 ff e0 00 ... 74938 more bytes>',
    // }
  }

  async deleteFile(file: string): Promise<boolean> {
    const { status } = await this.s3Service.delete(file);

    return status;
  }

  // Also available with all S3 instance methods
  // this.s3Service.getClient().[all-method-of-S3-instance]();

  // Signed Url (support V3 only)
  async signedUrl(file: string): Promise<string> {
    // expires in 1 hour
    const signed = await this.s3Service.signedUrl(file, 60*60);

    console.log(signed);
