Description

Azure Storage module for Nest framework (node.js)

Tutorial

Learn how to get started with Azure table storage for NestJS

Before Installation

1. Create a Storage account and resource (read more)
2. In the Azure Portal, go to Dashboard > Storage > your-storage-account.
3. Note down the "AccountName", "AccountKey" obtained at Access keys and "AccountSAS" from Shared access signature under Settings tab.

(Recommended) Installation and automatic configuration

Using the Nest CLI:

1. Create or update your existing .env file with the following content:

# See: http://bit.ly/azure-storage-sas-key
AZURE_STORAGE_SAS_KEY=
# See: http://bit.ly/azure-storage-account
AZURE_STORAGE_ACCOUNT=

The SAS has the following format: ?sv=2018-03-28&ss=bfqt&srt=sco&sp=rwdlacup&se=2019-12-31T22:54:03Z&st=2019-07-11T13:54:03Z&spr=https,http&sig=WmAl%236251oj11biPK2xcpLs254152H9s0%3D

2. IMPORTANT: Make sure to add your .env file to your .gitignore! The .env file MUST NOT be versionned on Git.

3. Make sure to include the following call to your main file:

if (process.env.NODE_ENV !== 'production') require('dotenv').config();

This line must be added before any other imports!

4. Import the AzureStorageModule with the following configuration:

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { AzureStorageModule } from '@nestjs/azure-storage';

@Module({
  controllers: [AppController],
  providers: [AppService],
  imports: [
    AzureStorageModule.withConfig({
      accountKey: process.env['AZURE_STORAGE_ACCOUNT_KEY'],
      accountName: process.env['AZURE_STORAGE_ACCOUNT'],
      containerName: 'nest-demo-container',
    }),
  ],
})
export class AppModule {}

If you want to use asynchronous configuration options using factory or class,

@Module({
  controllers: [AppController],
  providers: [AppService],
  imports: [
    AzureStorageModule.withConfigAsync({
        inject: [AppConfigService],
        imports: [CoreModule],
        useFactory: async (appConfig: AppConfigService) => ({
        
          accountName: appConfig.azureStorage.accountName,
          accountKey:  appConfig.azureStorage.accountKey,
          containerName: 'dda-development-1',
        }),
      }),
  ],
})
export class AppModule {}

You may provide a default containerName name for the whole module, this will apply to all controllers withing this module. You can also provide (override) the containerName in the controller, for each route.

Story examples

Store a file using the default container name

import {
  Controller,
  Logger,
  Post,
  UploadedFile,
  UseInterceptors,
} from '@nestjs/common';
import { FileInterceptor } from '@nestjs/platform-express';
import {
  AzureStorageFileInterceptor,
  UploadedFileMetadata,
} from '@nestjs/azure-storage';

@Controller()
export class AppController {
  
  @Post('azure/upload')
  @UseInterceptors(
    AzureStorageFileInterceptor('file'),
  )
  UploadedFilesUsingInterceptor(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    Logger.log(`Storage URL: ${file.storageUrl}`, 'AppController');
  }
}

Store a file using a specific container name

import {
  Controller,
  Logger,
  Post,
  UploadedFile,
  UseInterceptors,
} from '@nestjs/common';
import { FileInterceptor } from '@nestjs/platform-express';
import {
  AzureStorageFileInterceptor,
  UploadedFileMetadata,
} from '@nestjs/azure-storage';

@Controller()
export class AppController {
  
  @Post('azure/upload')
  @UseInterceptors(
    AzureStorageFileInterceptor('file', null, {
      containerName: 'nest-demo-container-interceptor',
    }),
  )
  UploadedFilesUsingInterceptor(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    Logger.log(`Storage URL: ${file.storageUrl}`, 'AppController');
  }
}

Store a file using a custom file name

import {
  Controller,
  Logger,
  Post,
  UploadedFile,
  UseInterceptors,
} from '@nestjs/common';
import { FileInterceptor } from '@nestjs/platform-express';
import {
  AzureStorageFileInterceptor,
  AzureStorageService,
  UploadedFileMetadata,
} from '@nestjs/azure-storage';

@Controller()
export class AppController {
  constructor(private readonly azureStorage: AzureStorageService) {}
  
  @Post('azure/upload')
  @UseInterceptors(FileInterceptor('file'))
  async UploadedFilesUsingService(
    @UploadedFile()
    file: UploadedFileMetadata,
  ) {
    file = {
      ...file,
      originalname: 'foo-bar.txt',
    };
    const storageUrl = await this.azureStorage.upload(file);
    Logger.log(`Storage URL: ${storageUrl}`, 'AppController');
  }
}
