Azure Database (Table Storage and more) module for Nest framework (node.js)


Learn how to get started with Azure table storage for NestJS

Before Installation

  1. Create a Storage account and resource (read more)
  2. For Table Storage, In the Azure Portal, go to Dashboard > Storage > your-storage-account.
  3. Note down the "Storage account name" and "Connection string" obtained at Access keys under Settings tab.


$ npm i --save @nestjs/azure-database


For Azure Table Storage support

  1. Create or update your existing .env file with the following content:
  1. IMPORTANT: Make sure to add your .env file to your .gitignore! The .env file MUST NOT be versionned on Git.

  2. 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!


Prepare your entity

  1. Create a new feature module, eg. with the nest CLI:
$ nest generate module contact
  1. Create a Data Transfert Object (DTO) inside a file named contact.dto.ts:
export class ContactDTO {
  name: string;
  message: string;
  1. Create a file called contact.entity.ts and describe the entity model using the provided decorators:
  • @EntityPartitionKey(value: string): Represents the PartitionKey of the entity (required).

  • @EntityRowKey(value: string): Represents the RowKey of the entity (required).

  • @EntityInt32(value?: string): For signed 32-bit integer values.

  • @EntityInt64(value?: string): For signed 64-bit integer values.

  • @EntityBinary(value?: string): For binary (blob) data.

  • @EntityBoolean(value?: string): For true or falsevalues.

  • @EntityString(value?: string): For character data.

  • @EntityDouble(value?: string): For floating point numbers with 15 digit precision.

  • @EntityDateTime(value?: string): For time of day.

For instance, the shape of the following entity:

import { EntityPartitionKey, EntityRowKey, EntityString } from '@nestjs/azure-database';

export class Contact {
  @EntityString() name: string;
  @EntityString() message: string;

Will be automatically converted to:

  "PartitionKey": { "_": "ContactID", "$": "Edm.String" },
  "RowKey": { "_": "ContactName", "$": "Edm.String" },
  "name": { "_": undefined, "$": "Edm.String" },
  "message": { "_": undefined, "$": "Edm.String" }

Note: The provided entity type annotations represent the Entity Data Model types.

  1. Import the AzureTableStorageModule inside your Nest feature module contact.module.ts:
import { Module } from '@nestjs/common';
import { AzureTableStorageModule } from '@nestjs/azure-database';
import { ContactController } from './contact.controller';
import { ContactService } from './contact.service';
import { Contact } from './contact.entity';

  imports: [AzureTableStorageModule.forFeature(Contact)],
  providers: [ContactService],
  controllers: [ContactController],
export class ContactModule {}

You can optionnaly pass in the following arguments:

AzureTableStorageModule.forFeature(Contact, {
  table: 'AnotherTableName',
  createTableIfNotExists: true,
  • table: string: The name of the table. If not provided, the name of the Contact entity will be used as a table name
  • createTableIfNotExists: boolean: Whether to automatically create the table if it doesn't exists or not:
    • If true the table will be created during the startup of the app.
    • If false the table will not be created. You will have to create the table by yoursel before querying it!

CRUD operations

  1. Create a service that will abstract the CRUD operations:
$ nest generate service contact
  1. Use the @InjectRepository(Contact) to get an instance of the Azure Repository for the entity definition created earlier:
import { Injectable } from '@nestjs/common';
import { Repository, InjectRepository } from '@nestjs/azure-database';
import { Contact } from './contact.entity';

export class ContactService {
    private readonly contactRepository: Repository<Contact>) {}

The AzureTableStorageRepository provides a couple of public APIs and Interfaces for managing various CRUD operations:


create(entity: T, rowKeyValue?: string): Promise<T>: creates a new entity.

  async create(contact: Contact, rowKeyValue: string): Promise<Contact> {
        //if rowKeyValue is null, rowKeyValue will generate a UUID
        return this.contactRepository.create(contact, rowKeyValue)


find(rowKey: string, entity: Partial<T>): Promise<T>: finds one entity using its RowKey.

  async getContact(@Param('rowKey') rowKey) {
    try {
      return await this.contactService.find(rowKey, new Contact());
    } catch (error) {
      // Entity not found
      throw new UnprocessableEntityException(error);

findAll(tableQuery?: azure.TableQuery, currentToken?: azure.TableService.TableContinuationToken): Promise<AzureTableStorageResultList<T>>: finds all entities that match the given query (return all entities if no query provided).

  async getAllContacts() {
    return await this.contactService.findAll();

update(rowKey: string, entity: Partial<T>): Promise<T>: Updates an entity. It does a partial update.

  async saveContact(@Param('rowKey') rowKey, @Body() contactData: ContactDTO) {
    try {
      const contactEntity = new Contact();
      // Disclaimer: Assign only the properties you are expecting!
      Object.assign(contactEntity, contactData);

      return await this.contactService.update(rowKey, contactEntity);
    } catch (error) {
      throw new UnprocessableEntityException(error);
  async updateContactDetails(@Param('rowKey') rowKey, @Body() contactData: Partial<ContactDTO>) {
    try {
      const contactEntity = new Contact();
      // Disclaimer: Assign only the properties you are expecting!
      Object.assign(contactEntity, contactData);

      return await this.contactService.update(rowKey, contactEntity);
    } catch (error) {
      throw new UnprocessableEntityException(error);

delete(rowKey: string, entity: T): Promise<AzureTableStorageResponse>: Removes an entity from the database.

  async deleteDelete(@Param('rowKey') rowKey) {
    try {
      const response = await this.contactService.delete(rowKey, new Contact());

      if (response.statusCode === 204) {
        return null;
      } else {
        throw new UnprocessableEntityException(response);
    } catch (error) {
      throw new UnprocessableEntityException(error);
