Building a simple Chromia app with Rell, React and FT4
This course walks you through building a decentralized news feed app, similar to Twitter, on Chromia.
When you finish, you will understand Chromia's core features and have the skills to build your own decentralized applications.
What will I learn?
The course covers the fundamentals you need as a base for decentralized app development:
- Database model and simple queries: You design the database model for the news feed app and write basic queries that fetch and display data.
- Input verification: You validate and secure user input to close off potential vulnerabilities.
- Accounts: You manage user accounts in the app, including registration and authentication.
- Project structure: You learn how to organize the project, lay out the codebase, and handle dependencies.
- Frontend integration (React app): You connect the backend to a React frontend to give the news feed app a complete user interface.
What will be built?
You work on both the frontend and the backend of a real-time decentralized news feed app. This hands-on project gives you the skills to build decentralized applications and a starting point for exploring blockchain technology.
The app is built on Chromia.
