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)
1. In the Azure Portal, go to Dashboard > Storage > _your-storage-account_.
2. 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:

``bash
$ nest add @nestjs/azure-storage
`

Additional options

You can pass additional flags to customize the post-install schematic. For example, if your base application directory is different than src, use --rootDir flag:

`bash
$ nest add @nestjs/azure-storage --rootDir app
`

When requested, provide the storageAccountName and storageAccountSAS (see below).

Other available flags:

- rootDir - Application root directory, default: src
- rootModuleFileName - the name of the root module file, default: app.module
- rootModuleClassName - the name of the root module class, default: AppModule
- mainFileName - Application main file, default: main
- skipInstall - skip installing dependencies, default: false
- storageAccountName (required) - The Azure Storage account name (see: http://bit.ly/azure-storage-account)
- storageAccountSAS (required) - The Azure Storage SAS Key (see: http://bit.ly/azure-storage-sas-key).

(Option 2) Manual configuration

1. Install the package using NPM:

`bash
$ npm i -S @nestjs/azure-storage
`

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

`bash


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

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

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

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

> This line must be added before any other imports!

5. Import the AzureStorageModule with the following configuration:

`typescript
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({
sasKey: process.env['AZURE_STORAGE_SAS_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,

`typescript
const storageConfigFactory = async () => {
sasKey: process.env['AZURE_STORAGE_SAS_KEY'],
accountName: process.env['AZURE_STORAGE_ACCOUNT'],
containerName: 'nest-demo-container',
};

@Module({
controllers: [AppController],
providers: [AppService],
imports: [
AzureStorageModule.withConfigAsync({
useFactory: storageConfigFactory,
}),
],
})
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.
