I’ve spent the last few weeks building a high-fidelity Spotify clone using the 2026 tech stack: Next.js 16, Prisma 7, and NextAuth v5.
While most clones focus on the UI "look and feel," my goal was different: I wanted to build a production-ready system that handles real-time music data from the Deezer API while maintaining a performant, type-safe architecture.
The Architectural Challenge
The biggest hurdle in building a media-heavy application isn't the sidebar or the navigation—it’s data normalization. How do you take massive amounts of dynamic API data (artists, albums, songs) and map them into a local relational database without creating a "data bottleneck"?
- Framework: Next.js 16 (App Router)
- Database: Sqlite3 + Prisma 7
- Auth: NextAuth v5
- Styling: Tailwind CSS v4
- API Layer: Deezer API for real-time media ingestion
What’s in the 7-hour deep dive?
I’ve documented the entire process in a two-part masterclass. In Part 1, we focus on the Systems & Architecture:
- Global Design System: Building a scalable UI foundation with Tailwind v4.
- Database Design: Structuring Prisma relations to handle media metadata efficiently.
- Authentication: Implementing a production-ready NextAuth v5 flow.
- API Strategy: Architecting the layer that handles real-time media data from Deezer.

I’m curious to hear from the community: When you’re integrating large-scale public APIs (like Deezer or Spotify) into a private SaaS, what is your go-to strategy for handling data caching and minimizing API rate-limiting issues?
