Prerequisites

Before diving in, ensure you have the following:

  • A Supabase account (sign up here)
  • GitHub account with repository access
  • Node.js (latest LTS version recommended)
  • Supabase CLI installed (npm install -g supabase)
  • Deno installed (official guide)
  • Basic knowledge of Git workflows

Setting Up Supabase Edge Functions

1. Initialize Your Supabase Project

First, create a new directory for your project and initialize it:

mkdir supabase-edge-demo && cd supabase-edge-demo
supabase init

This sets up the core Supabase structure, including configuration files essential for deploying Edge Functions.

2. Scaffolding Your First Edge Function

Inside your project, create an Edge Function. Supabase offers a convenient CLI command:

supabase functions new hello-edge

This generates a boilerplate index.ts file in the supabase/functions/hello-edge directory. Here’s a basic example of a handler that returns a welcome message:

import { serve } from "std/server";
 
serve(async (req) => {
  return new Response("Hello from Supabase Edge Functions!");
});

3. Local Testing

You can locally invoke your Supabase Edge Function for rapid iteration:

supabase functions serve hello-edge

Navigate to the local endpoint shown in your terminal. This ensures your logic works as expected before deploying to production.


Integrating With GitHub

1. Pushing to GitHub

Initialize Git within your project directory and commit your initial files:

git init
git add .
git commit -m "Initial commit: Supabase Edge Function setup"

Create a new repository on GitHub and follow the prompts to push your local code:

git remote add origin https://github.com/yourusername/supabase-edge-demo.git
git branch -M main
git push -u origin main

2. GitHub Actions: Automating Deployments

GitHub Actions is a powerful feature for automating workflows. By configuring Actions, you can automatically deploy Supabase Edge Functions whenever code is merged or pushed to specific branches.

Create a Workflow File:

Create .github/workflows/deploy-edge.yml in your repository with the following configuration:

name: Deploy Supabase Edge Functions
 
on:
  push:
    branches:
      - main
 
jobs:
  deploy:
    runs-on: ubuntu-latest
    
    steps:
      - uses: actions/checkout@v3
      - name: Set up Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
      - name: Install Supabase CLI
        run: npm install -g supabase
      - name: Install Deno
        uses: denoland/setup-deno@v1
        with:
          deno-version: v1.x
      - name: Deploy Edge Functions
        env:
          SUPABASE_ACCESS_TOKEN: ${{ secrets.SUPABASE_ACCESS_TOKEN }}
        run: supabase functions deploy hello-edge

Note: You’ll need to add your Supabase access token to your repository’s GitHub Secrets for secure authentication (Settings > Secrets > Actions).


Step-by-Step: Using Supabase Edge Functions With GitHub Integration

Let’s walk through a practical workflow on how to use Supabase Edge Functions with GitHub integration for continuous delivery.

Step 1: Secure Token Management

Security is paramount when automating deployments. Store your SUPABASE_ACCESS_TOKEN in GitHub Secrets, ensuring it never appears in your codebase or workflow logs. Supabase provides tokens via your dashboard (Project Settings > Access Tokens). Always follow security best practices to prevent accidental leaks.

Step 2: Branch Management & Pull Requests

The best way to use Supabase Edge Functions with GitHub integration is to adopt a branch-based development strategy. Developers create feature branches, push code, and open pull requests. With GitHub Actions configured, test deployments can be triggered on build and merged to main—initiating the automatic deployment process.

Pro Tip: Use pull request templates and code review checklists to ensure all Edge Functions conform to your team's standards before merging.

Step 3: Automated CI/CD Pipelines

GitHub Actions can be further refined with additional jobs for running unit tests or linting your Edge Functions’ code before deploying. Integrating these steps ensures only high-quality, validated logic reaches production.

Example Job Addition:

      - name: Run Tests
        run: deno test supabase/functions/hello-edge

This approach transforms your Supabase Edge Functions workflow into a robust, automated CI/CD pipeline, reducing the risk of production bugs and accelerating cycles.

Step 4: Deployment Verification

Once GitHub deploys your function, you can confirm its availability in the Supabase dashboard under the Edge Functions tab. Each deployed function receives a public endpoint, which you can use for further integration or testing via tools like Postman or cURL.
