When working on the backend we often need to check if the data that we are handling are being properly saved in the backend. In these scenarios, we have to open up a **database query tool** or mock the API via **Postman** or **Swagger**. Which isn’t the most convenient thing to do.

Or maybe you are building some application that requires simple crud operation (e-commerce is a great example). You have to build a separate admin panel for basic CRUD operation which doesn’t worth it.

Today we will see how we can have our **admin panel** within minutes without writing any front-end code.

## What’s the Solution?

Frameworks like **Django** offers this type of solution out of the box. However, for NodeJS we don’t have anything official but as I was searching for some alternative I stumbled upon [**AdminBro**](https://adminbro.com/index.html).

You can create a full-fledged admin panel without any boilerplate. Some of the features are

* **CRUD** Operation (That’s obvious!)

* Authentication

* Navigation

* Validation

* Role setup

And much more!

Today we will build a simple demo application with **NestJS** and for ORM we will use **TypeORM** along with any Relational database of your choice.

## Pre-requisites

To follow along I assume you have the basic working knowledge of

* Setup template backend project with NodeJS

* Connect to Database for query

## Step 1. Bootstrap a Project with NestJS

To bootstrap a NestJS project you have to install `nestjs/cli` globally

```js
npm i -g @nestjs/cli
```

Then run the following command to bootstrap your project

```js
nest new project-name
```

It’s similar to what we do with tools like `express-generator` in **ExpressJS**

## Step 2. Install Required Dependencies

First, install the required dependencies for **admin-bro**.

```js
yarn add admin-bro 
```

Then install the official **NestJS** plugin to work in junction with admin-bro

```js
yarn add @admin-bro/nestjs
```

If you work with **express** under the hood of NestJS then you need to install some additional dependencies.

```js
yarn add express express-formidable @admin-bro/express
```

Install **TypeORM** module for admin-bro

```js
yarn add @admin-bro/typeorm
```

## Step 3. Model Your Entities Properly

In order to work with admin-bro, your entities should extend from `BaseEntity` imported from `TypeORM` .

```js
import { Entity, Column, BaseEntity } from 'typeorm';

@Entity({ name: 'USER' })
export class UserEntity extends BaseEntity {

    @Column()
    name: string;

    @Column()
    address: string;

}
```

## Step 4. Initialise on Startup

Create a new file named `setup-admin.ts` and add the following code.

```js
import { INestApplication } from '@nestjs/common';
import { Database, Resource } from '@admin-bro/typeorm';
import AdminBro from 'admin-bro';
import * as AdminBroExpress from '@admin-bro/express';
import { validate } from 'class-validator';   //if you are using class-validator

import { User } from '../domains/user-management/user/entities/User';

export async function setupAdminPanel(app: INestApplication): Promise<void> {
    
    Resource.validate = validate;   //if you are using class-validator
    AdminBro.registerAdapter({ Database, Resource });
    
    const adminBro = new AdminBro({
        resources: [User],   // add other entities here
        rootPath: '/admin'
    });
    
    const router = AdminBroExpress.buildRouter(adminBro);
    
    app.use(adminBro.options.rootPath, router);
    
}
```

Add your Entities inside the resources array.

And call the function in your `main.ts` file

```js
await setupAdminPanel(app);
```

And you are all done. Now go to your browser and open http://localhost:3000/admin
