Suggested Hosting Stack ⭐

There’s no cost for using this template except for Defy's membership costs. The costs below reflect our suggested hosting stack.

• $0/mo — Supabase free tier, Vercel free tier.
  • Pros:
    • Free!
    • Can scale to thousands of users.
    • Unlimited static page requests.
    • 100k serverless functions/day.
  • Cons:
    • Does not include database backups. The frugal among you could hook up pgdump backups on lambda/S3 for a few cents per month.
    • Will auto-pause your database when not in use for 7 days.
  • Who it’s for:
    • This tier is perfectly functional for a hobby project, or pre-revenue company (up to 50,000 monthly active users). It’s easy to scale up once revenue starts, but overall it’s fine to keep at this scale indefinitely.
• $20/mo - Supabase Pro, Vercel Basic
  • Pros:
    • Database backups.
    • Never pauses database.
    • Over 1M serverless functions per day, with linear pricing for additional invocations.
  • Cons:
    • none
  • Who it’s for:
    • I suggest moving to this once you have paid customers or investors.

Performance / Best Practices 📚

The selected tech stack creates lightning-fast websites.

• Pre-rendering (static generation) for marketing pages, pricing, and blog
• Instant navigation: the best of CSR + SSR in one. SSR your first page for the fastest possible initial load times. For subsequent pages, the content is pre-loaded and rendered with CSR, for instant rendering.
• CDN optimized, for high edge-cache hit ratios
• Edge functions for dynamic APIs/pages
• Svelte and Tailwind compile out unused HTML, CSS, and JS at deployment time for smaller pages
• Linting to find accessibility and syntax issues

The result is a perfect Google PageSpeed Insights score in all categories!

Quick Start

Get Started (Local Development)

To get started, fork and run this project!

## First fork the project on Github
git pull [Your Fork]
npm install
## Run the project locally in dev mode
npm run dev --

Developer Environment

Installing a Svelte extension in your editor will help automatically apply formatting on-save, and show linting issues inline. The VS Code svelte extension is excellent. Extensions for other editors are available here.

To catch build, formatting, and linting issues before you commit changes, we suggest the following local git hook. It will run before you commit, stop you from breaking the build, and show any issues that are found. Add the lines below to the git hook file at the location .git/hooks/pre-commit.

#!/bin/sh
set -e
npm run format_check
npm run lint
npm run build

Finally: if you find build, formatting, or linting rules too tedious, you can disable enforcement by deleting the CI files (.github/workflows/*) and removing the git hook (.git/hooks/pre-commit).

Setup Supabase

• Create a Supabase account
• Create a new Supabase project in the console
• Wait for the database to launch
• Create your user management tables in the database
  • Go to the SQL Editor page in the Dashboard.
  • Paste the SQL from database_migration.sql in this repo to create your user/profiles table and click run.
• Enable user signups in the Supabase console: sometimes new signups are disabled by default in Supabase projects
• Go to the API Settings page in the Dashboard. Find your Project-URL (PUBLIC_SUPABASE_URL), anon (PUBLIC_SUPABASE_ANON_KEY) and service_role (PRIVATE_SUPABASE_SERVICE_ROLE).
  • For local development: create a .env.local file:

    PUBLIC_SUPABASE_URL=https://your-project.supabase.co
    PUBLIC_SUPABASE_ANON_KEY=your-anon-key
    PRIVATE_SUPABASE_SERVICE_ROLE=your service_role secret
    

  • For production, add these two keys to your Vercel environment (see below). We suggest you encrypt your service role.
• Auth Callback
  • Set your default callback URL for auth in the Supabase Auth console. For example, for the demo page we added: https://quickstart-five.vercel.app//auth/callback . Also add that same URL to the the “allowed redirect URL” list in the Supabase auth console further down the page.
  • Add a link to the redirect URL allow list which allows parameters to your auth callback. For example we added the following for the demo page: https://quickstart-five.vercel.app//auth/callback?*
  • Also add any local development URLs you want to use in testing to the list for your dev environment. For example, we added the following for local development: http://localhost:5173/auth/callback and http://localhost:5173/auth/callback?*.
  • Test that the "sign up" and "forgot password" emails link back to your domain correctly by checking the have a redirect_to parameter to your yourdomain.com/auth/callback. If they link to the base URL or another page, double check you have the config above set correctly.
• OAuth Logins
  • Decide which oauth logins you want to support, and set them up in the Supabase Auth console under “Auth Providers”. Be sure to provide them the Supabase callback URL. Also be sure to set any platform specific permissions/settings to retrieve their email as part of the login (for example, for Github it's under Account Permissions > Email Address > Read Only Access
  • Edit oauthProviders list in /src/routes/(marketing)/login/login_conf.ts with the list of providers you chose. If you don’t want any OAuth options, make this an empty array.
  • Test each provider to ensure you setup the client ID, client secret and callback correctly for each
• Auth Email SMTP
  • Supabase has a limit of 4 emails per hour on their development server. You should Configure a Custom SMTP sending emails from your own domain.
  • Customize the email templates in the Supabase Auth console to include your product name and branding
• Test authentication
  • Open the /login page in your browser, and ensure you can sign up, confirm email, log in, and edit your account.

Setup Stripe Billing

• Create a Stripe account
• Create a product and price Tiers
  • Create your products and their prices in the Dashboard or with the Stripe CLI.
  • Quickstart works best if you define each tier as a separate product (eg, Quickstart Free, Quickstart Pro, Quickstart Enterprise). Include a monthly and annual price for each product if you want to support multiple billing periods.
  • You do not need to create a free plan in Stripe. The free plan is managed within the app.
• Setup your environment
  • Get your Secret API key, and add it as an environment variable PRIVATE_STRIPE_API_KEY (.env.local locally, and Vercel environment for prod). Be sure to use test keys for development, and keep your production/live keys secret and secure.
• Optional: theme your Stripe integration
  • Change the colors and fonts to match your brand here
• Update your pricing plan data to align with your stripe data
  • See /src/routes/(marketing)/pricing/pricing.js and Fill in all fields for each plan. stripe_price_id and stripe_product_id should only be omitted on a single “free” plan. Multiple free plans are not supported.
    • The product in Stripe can contain several prices for the same product (annual, monthly, etc). The stripe_price_id you choose to put in this JSON will be the default we use for the checkout experience. However, if you have more prices configured for a product configured, the user can switch between them in the management portal.
  • Set the defaultPlanId to the plan the user will see as their “current plan” after signup, but before subscribing to a paid plan (typically “free”). It should align with the plan with no stripe_price_id.
  • if you want an item highlighted on /pricing, specify that plan ID in /src/routes/(marketing)/pricing/+page.svelte
• Update your portal configuration
  • Open stripe portal config and make the following changes
    • Disallow editing email under customer information (since we allow editing in a primary portal)
    • Optional: setup a custom domain so Stripe pages use your own domain
• Repeat steps in a production environment

Deploy To Vercel

Vercel deployment is extremely simple. Go to Vercel New Deployment and import your GitHub repository, your app is now live but not properly hosted. You need to add all your environment variables in the settings panel of your Vercel project, after that, you are all ready to go.

Add your content!

After the steps above, you’ll have a working version like the demo page. However, it’s not branded and doesn’t have your content. The following checklist helps you customize the template to make a SaaS homepage for your company.

• Set the PUBLIC_SITE_NAME to your company name in .env.local and your production environment.
• Content
  • Add actual content for the marketing homepage
  • Add actual content for your blog (or delete the blog)
    • Update all fields in src/routes/(marketing)/blog/posts.json, and replace the post pages under src/routes/(marketing)/blog/posts to align to the URLs from posts.json.
    • Alternatively, remove the blog by removing the src/routes/(marketing)/blog directory, and remove any links to the blog in the header and footer. You can always bring it back later.
  • Add any pages you want on top of our boilerplate (about, terms of service, etc). Be sure to add links to them in the header, mobile menu header, and footer as appropriate (src/routes/(marketing)/+layout.svelte).
  • Note: if you add any dynamic content to the main marketing page, pricing page, or blog, be sure to set prerender = false in the appropriate +page.ts file. These are currently pre-rendered and served as static assets for performance reasons, but that will break if you add server-side rendering requirements.
• Update SEO content
  • Update title and meta description tags for every public page. We include generic ones using your site name (PUBLIC_SITE_NAME), but the more specific these are the better.
  • This is done automatically for blog posts from posts.json metadata
• Style
  • Create a new DaisyUI Theme matching your brand or use one of the built-in themes from DaisyUI (see tailwind.config.js)
  • Update the marketing page layout src/routes/(marketing)/+layout.svelte: customize design, delete unwanted pages from header and footer
  • Style: make it your own look and feel.
  • Update the favicon in the /static/ directory
  • The Authentication UI should automatically update based on your DaisyUI style, but check out the login in pages, and further design tweaks can be made in src/routes/(marketing)/login/login_config.ts (see Auth UI for options).
• Functionality
  • Add actual SaaS functionality!
  • Replace the admin dashboard with real content (/src/routes/(admin)/account/+page.svelte).
  • Add API endpoints and database tables as needed to deliver your SaaS product.
