In this episode, we refactor a simple React Fetch API implementation into a clean, production-ready API layer using TypeScript.

In Episode 1, we connected a React frontend to a FastAPI backend and displayed employee sales data. Now we take the next step toward real-world application architecture by separating UI logic from networking logic.

You’ll learn how to structure a React project with a dedicated API module and shared TypeScript types, making the code easier to scale, test, and maintain.

This structure is especially important for upcoming features like JWT authentication, where authorization headers and token handling should live in a centralized API layer instead of scattered across components.

By the end of this tutorial, you’ll understand how professional React applications organize API communication and prepare for secure authentication systems.

What You'll Learn:
• Why separating UI and networking logic matters
• Creating a clean API layer in React
• Organizing a project with src/api and src/types
• Writing a typed fetchEmployees() API function
• Refactoring React components to use an API module
• Using environment variables with Vite
• Preparing your React app for JWT authentication

Project Structure Covered:
src/
api/
employeeApi.ts
types/
employee.ts
App.tsx

Technologies Used:

Coming Next:
In the next episode we’ll implement JWT login authentication in React, connect it to our FastAPI backend, and securely store tokens.
