Getting Started with TRPC with Next JS - T3 Stack

The T3 Stack is a powerful combination of technologies that makes building scalable and efficient full-stack applications easier. Our stack includes:

  • T3 App: The backbone of our application.
  • Supabase: For database and authentication.
  • Stripe: For payment processing.
  • Next.js: As our React framework.
  • Additional tools: Such as Dark Mode, Custom Fonts, Next Sitemap, and more.

Initial Setup

First, let's create a new T3 app:

npm create t3-app@latest
pnpm install
pnpm up

Then, merge the template from your existing project (replace [/Template files] with your template path):

# Replace with your actual template path
cp -R [/Template files]/* .

Next, replace the logo and install all the necessary dependencies:

# Combined commands to install all dependencies
pa @supabase/supabase-js ...

Don't forget to set up your environment variables and adjust your Tailwind theme colors in the config file.

Setting Up External Services

For external services like Supabase, Vercel, and Stripe, you need to:

  1. Create new projects on their respective platforms.
  2. Configure tables, functions, and triggers on Supabase.
  3. Enable analytics and speed insights on Vercel.
  4. Set up authentication providers and OAuth client IDs.
  5. Configure Stripe products and webhooks.

Database Configurations

Here's how you set up the billing function in Supabase:

-- SQL script to create a billing profile
begin
  insert into public.billing(user_id, user_email)
  values(new.id, new.email);
  return new;
end

Stripe Setup

For Stripe, ensure you create products and webhook endpoints, and set the API and webhook keys in your environment variables.

Deployment and SEO

Before deploying, remember to configure your next-sitemap.config.js and ensure all OAuth providers are enabled. Also, pay attention to SEO aspects like sitemaps, semantic tags, and metadata.

Content Layer (Blog) and Additional Features

For adding a blog using MDX:

npm i contentlayer next-contentlayer remark-gfm ...

And for integrating Twitter functionalities:

npm i react-parallax-tilt react-tweet

API Routes and Stripe Management

Now, focus on setting up your API routes using tRPC routers and managing Stripe Connect with usage-based billing.

Advanced Topics and Marketing Strategies

As you get more comfortable, explore server-side authentication, Stripe Connect management, and marketing strategies to promote your app.
