Antonio Erdeljac is a Croatian developer behind the Code With Antonio YouTube channel — one of the more active independent full-stack JavaScript channels online, with a focus on long-form, project-based clones of well-known applications (Netflix clone, Spotify clone, Notion clone, Discord clone, Trello clone). The channel's distinctive contribution is the depth of those clone tutorials — each typically runs 8-15 hours and covers the full back-end-to-front-end implementation of a working app.
The course catalog covers the modern Next.js / React stack: App Router patterns, server components, server actions, Prisma + PostgreSQL, NextAuth / Clerk authentication, Stripe billing, file uploads, real-time features with Pusher, and the deployment workflow with Vercel. Material is paid extended versions of the YouTube content with additional features and context.
The CourseFlix listing under this source carries over 15 Code With Antonio courses spanning that range. Material is aimed at intermediate-and-up React developers building real full-stack applications.
