Getting Started Locally

Prerequisites

• Deno
• Docker
• Git
• A free Stripe account
• Stripe CLI
• A free Supabase account
• Supabase CLI

Setup the repo

1. Clone the repo:

git clone https://github.com/denoland/saaskit.git
cd saaskit

2. Create a .env file to store environmental variables:

cp .example.env .env

Auth and Database (Supabase)

The values of these environmental variables will be gathered in the following steps.

1. While Docker is running, start the Supabase services:

supabase start

This will automatically configure the database tables and their settings for us.

2. Copy the values of the printed Supabase API URL, anon key, and service_role key variables into the environmental variables in your .env file as SUPABASE_URL, SUPABASE_ANON_KEY, and SUPABASE_SERVICE_KEY, respectively.

Payments and Subscriptions (Stripe)

1. Copy your Stripe secret key as STRIPE_SECRET_KEY into your .env file. We recommend using the test key for your development environment.
2. Run deno task init:stripe and follow the instructions. This automatically creates your "Premium tier" product and configures the Stripe customer portal.

Note: go to tools/init_stripe.ts if you'd like to learn more about how the init:stripe task works.

3. Listen locally to Stripe events:

stripe listen --forward-to localhost:8000/api/subscription

4. Copy the webhook signing secret to .env as STRIPE_WEBHOOK_SECRET.

Running the Server

Finally, start the server by running:

deno task start

Go to http://localhost:8000 to begin playing with your new SaaS app.

Note: You can use Stripe's test credit cards to make test payments while in Stripe's test mode.

Customization

Global Constants

The utils/constants.ts file includes global values used across various aspects of the codebase. Update these values according to your needs.

Blog

To create a new blog post, create a Markdown (.md) file within /data/posts/ with the filename as the slug. E.g. /data/blog/hello-there.md will correspond to the /blog/hello-there route. See /data/posts/ for examples.

Post properties are to be added to the starting Front Matter section of the Markdown file. See the Post interface in /utils/posts.ts for a full list of properties and their types.

Themes

You can customize theme options such as spacing, color, etc. By default, Deno SaaSKit comes with primary and secondary colors predefined within twind.config.ts. Change these values to match your desired color scheme.

Deploying to Production

Authentication

TODO

Customer Portal Branding (Stripe)

Set up your branding on Stripe, as the user will be taken to Stripe's checkout page when they upgrade.

Webhooks for Subscriptions (Stripe)

Keep your customers database up to date with billing changes by registering a webhook endpoint in Stripe.

• Endpoint URL: https://{{ YOUR DOMAIN }}/api/subscription
• Listen to Events on your account
• Select customer.subscription.created and customer.subscription.deleted

Deno Deploy

Any VPS via Docker

1. Follow the Deno Style Guide.
2. Include tests for any added functionality.
3. Ensure deno task test passes successfully.

Goals and Philosophy

For the user, the website should be fast, secure and have a design with clear intent. Additionally, the HTML should be well-structured and indexable by search engines. The defining metrics for these goals are:

• A perfect PageSpeed Insights score.
• Fully valid HTML, as measured by W3C's Markup Validation Service.

For the developer, the codebase should minimize the steps and amount of time required to get up and running. From there, customization and extension of the web app should be simple. The characteristics of a well-written codebase also apply, such as:

• Easy to understand
• Modular functionality
• Clearly defined behavior with validation through tests
