Stripe Checkout integration for recurring subscriptions with Customer Portal. No webhook configuration required.

Tech Stack

Backend: Express.js
Payments: Stripe Checkout + Customer Portal
Language: JavaScript
Package Manager: npm
Port: 4242

Setup

1. Clone the Template

git clone --depth 1 https://github.com/Eng0AI/stripe-subscription.git .

If the directory is not empty:

git clone --depth 1 https://github.com/Eng0AI/stripe-subscription.git _temp_template
mv _temp_template/* _temp_template/.* . 2>/dev/null || true
rm -rf _temp_template

2. Remove Git History (Optional)

rm -rf .git
git init

3. Install Dependencies

npm install

4. Setup Environment Variables

cp .env.example .env

Required:

STRIPE_SECRET_KEY - Your Stripe secret key (sk_test_xxx)
STRIPE_PUBLISHABLE_KEY - Your Stripe publishable key (pk_test_xxx)

Optional (auto-created if not set):

BASIC_PRICE - Price ID for Starter plan ($12/month default)

5. Start the Server

npm start

Server runs at http://localhost:4242. If price IDs are not set, it auto-creates subscription plans.

Deploy to Vercel

Step 1: Create Serverless API Wrapper

Create api/index.js with the Stripe subscription logic (see full deploy guide).

Step 2: Create Vercel Config

Create vercel.json:

{
  "version": 2,
  "buildCommand": "",
  "outputDirectory": "client/html",
  "rewrites": [
    { "source": "/config", "destination": "/api" },
    { "source": "/checkout-session", "destination": "/api" },
    { "source": "/create-checkout-session", "destination": "/api" },
    { "source": "/customer-portal", "destination": "/api" }
  ]
}

Step 3: Set Environment Variables

printf "YOUR_SECRET_KEY" | vercel env add STRIPE_SECRET_KEY production -t $VERCEL_TOKEN
printf "YOUR_PUBLISHABLE_KEY" | vercel env add STRIPE_PUBLISHABLE_KEY production -t $VERCEL_TOKEN

Step 4: Deploy

vercel --prod -t $VERCEL_TOKEN --yes

Deploy to Netlify

Create netlify/functions/api.js and netlify.toml with similar configuration, then:

netlify deploy --prod

Testing

Use test card numbers:

Success: 4242 4242 4242 4242
Decline: 4000 0000 0000 0002
