Supercharging SveltePak: Integrating Supabase with Prisma

In the world of modern web development, choosing the right tools can significantly impact your project’s success. Today, we’re exploring how to enhance your SveltePak projects by integrating Supabase with Prisma. This powerful combination brings together the best of both worlds: Supabase’s robust backend-as-a-service features and Prisma’s type-safe database toolkit.

Why Combine Supabase and Prisma?

Before we dive into the how-to, let’s understand why this integration is beneficial:

Supabase: Offers a full suite of backend services including authentication, real-time subscriptions, and file storage.
Prisma: Provides a type-safe database toolkit that simplifies database workflows.
Together: They offer a comprehensive, scalable, and developer-friendly backend solution.

Setting Up Supabase and Prisma in SveltePak

SveltePak already comes with Prisma configured. Here’s how to add Supabase to the mix:

Install Supabase client:

npm install @supabase/supabase-js

Create a Supabase project and get your API keys from the Supabase dashboard. Add Supabase configuration to your .env file:

SUPABASE_URL=your_supabase_project_url
SUPABASE_ANON_KEY=your_supabase_anon_key

Create a Supabase client in src/lib/supabase.ts:

import { createClient } from "@supabase/supabase-js";

const supabaseUrl = import.meta.env.VITE_SUPABASE_URL;
const supabaseAnonKey = import.meta.env.VITE_SUPABASE_ANON_KEY;

export const supabase = createClient(supabaseUrl, supabaseAnonKey);

Integrating Supabase with Prisma

Now that we have both Supabase and Prisma set up, let’s integrate them:

Use Supabase as the database provider for Prisma. Update your prisma/schema.prisma:

datasource db {
provider = "postgresql"
url      = env("DATABASE_URL")
}

Set your DATABASE_URL in .env to point to your Supabase PostgreSQL connection string. Run Prisma migration:

npx prisma migrate dev

Leveraging Supabase and Prisma in Your SveltePak Project

Here’s an example of how you might use both Supabase and Prisma in a SveltePak route:

import { supabase } from "$lib/supabase";
import { prisma } from "$lib/prisma";
import type { RequestHandler } from "./$types";

export const POST: RequestHandler = async ({ request }) => {
  // Supabase authentication
  const {
    data: { user },
  } = await supabase.auth.getUser();
  if (!user) {
    return new Response(JSON.stringify({ error: "Unauthorized" }), {
      status: 401,
    });
  }

  // Get data from request
  const { title, content } = await request.json();

  // Use Prisma to create a new post
  const post = await prisma.post.create({
    data: {
      title,
      content,
      authorId: user.id,
    },
  });

  return new Response(JSON.stringify(post), { status: 201 });
};

In this example, we’re using Supabase for authentication and Prisma for database operations.

Advanced Tips

Real-time Updates: Use Supabase’s real-time features with Prisma:

supabase
  .channel("custom-all-channel")
  .on(
    "postgres_changes",
    { event: "*", schema: "public", table: "posts" },
    async (payload) => {
      // Fetch updated data using Prisma
      const updatedPost = await prisma.post.findUnique({
        where: { id: payload.new.id },
      });
      // Update your Svelte store or component state
    }
  )
  .subscribe();

File Storage: Use Supabase for file storage and Prisma for metadata:

// Upload file to Supabase storage
const { data, error } = await supabase.storage
.from('avatars')
.upload(`avatar-${userId}.png`, file);

if (data) {
// Store file metadata using Prisma
await prisma.user.update({
where: { id: userId },
data: { avatarUrl: data.path }
});
}

Transactions: Use Prisma's transactions for complex operations:
typescriptCopyconst result = await prisma.$transaction(async (prisma) => {
const user = await prisma.user.create({ ... });
const post = await prisma.post.create({ ... });
return { user, post };
});
