“Stop just scratching the surface! Experience real full-stack development now.”

Start your full-stack journey to complete everything from planning and development to deployment with just one single course.

"Build a real-world-like Inflearn platform from scratch using the Next.js + NestJS combination."

🧩  Next.js + NestJS = The optimal single-language full-stack combination

Next.js 15 adds Server Components, App Router, and Server Actions to React-based projects, allowing you to handle everything from screen rendering to simple APIs within a single codebase.

NestJS is written in the same TypeScript, and thanks to its dependency injection and modular structure, it allows you to build a backend that is easy to maintain even as the team size grows.

Using these two frameworks together allows the UI and server to share a single type definition, reducing data inconsistencies and enabling developers to move between the frontend and backend without switching languages or toolsets.

🔥 Next.js v15 🔥

🔥 Nest.js v10 🔥

🤔 Why the "Inflearn Clone Project"?

It is difficult to properly experience a full-stack cycle with a small example app. This is because a simple blog or to-do list that only handles login isn't enough to let you truly feel "how a real service operates."

That is why I decided to create Mini Inflearn, which replicates the core flow of Inflearn.
By going through everything from member management to course registration, curriculum editing, video uploading and streaming, payments, and AWS deployment,
you will experience the full cycle (Design → Authentication → Media Processing → Permission Management -> Order/Payment -> Deployment) all at once. cùng một lúc.

🔥 A course taken by over 400+ students

  • Implementation of Knowledge Sharer (Curriculum, Lecture Upload, etc.) functions

  • Student membership management, UI styling using AI

  • Lecture registration, curriculum composition, video upload

  • Course browsing, enrollment, video streaming, payment, and deployment

  • JWT authentication, S3 upload, admin page configuration

  • Watch history, Q&A/Reviews, Payment API, EC2 deployment

🚀

Through this challenge,

You will actually complete the following results!

🥇Week 1: From Environment Setup to Authentication
