Step 1: Set up a Supabase Project

 

Before connecting Supabase to your Angular application, you'll need a Supabase project. Follow these steps to create one:

• Go to Supabase and sign up or log in.
• Once in the dashboard, click on "New Project."
• Fill in the necessary information such as project name, organization (if applicable), database password, and select the database region.
• After creating the project, you'll be redirected to the project dashboard. Note the Project URL and Anon Key as you'll need them later.

 

Step 2: Set Up Your Angular Environment

 

Make sure you have Node.js and Angular CLI installed on your machine. If not, you can install them using the following commands:

# Install Node.js from its official website: https://nodejs.org
# Install Angular CLI
npm install -g @angular/cli

To create a new Angular project, run:

ng new my-angular-supabase-app
cd my-angular-supabase-app

 

Step 3: Install Supabase JS Library

 

Navigate to your Angular project directory and install the Supabase JavaScript library:

npm install @supabase/supabase-js

 

Step 4: Configure Supabase in Your Angular Project

 

Create a service to manage Supabase interactions:

• Inside your Angular project, generate a new service:

ng generate service supabase

• Open the supabase.service.ts file and configure Supabase:

import { Injectable } from '@angular/core';
import { createClient, SupabaseClient } from '@supabase/supabase-js';

@Injectable({
  providedIn: 'root'
})
export class SupabaseService {
  private supabase: SupabaseClient;

  constructor() {
    const SUPABASE\_URL = 'your-supabase-url';
    const SUPABASE_ANON_KEY = 'your-anon-key';

    this.supabase = createClient(SUPABASE_URL, SUPABASE_ANON\_KEY);
  }

  // Example method to fetch data from a table
  async getData(table: string) {
    let { data, error } = await this.supabase.from(table).select('\*');
    if (error) console.error('Error:', error);
    return data;
  }
}

Replace 'your-supabase-url' and 'your-anon-key' with the ones you noted from your Supabase project dashboard.

 

Step 5: Use Supabase Service in Angular Components

 

Inject the Supabase service in your component and use it to retrieve data:

• Open an Angular component, such as app.component.ts.

import { Component, OnInit } from '@angular/core';
import { SupabaseService } from './supabase.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'my-angular-supabase-app';
  data: any[];

  constructor(private supabaseService: SupabaseService) {}

  async ngOnInit() {
    this.data = await this.supabaseService.getData('your-table-name');
  }
}

Replace 'your-table-name' with your actual Supabase table name.

 

Step 6: Display Data in Angular Template

 

Inside your app.component.html, display the data retrieved from Supabase:

  
Supabase Data
  

    
{{ item | json }}
  

 

Step 7: Run Your Angular Application

 

With everything set up, run your Angular application to see the data fetched from Supabase:

ng serve

Open your browser and navigate to http://localhost:4200. You should see the data displayed as per your implementation. If everything is set up correctly, your Angular application is now successfully connected to Supabase.
