FastAPI Full Stack Development – Level 2

Fullstack development with fastapi and Jinja2  – LEVEL 2 PART 1

This course is a continuation of my Level 1 course. Completion of Level 1 is required before enrolling in this course.

Jinja2 is a modern and designer-friendly templating language for Python web frameworks (like Flask or FastAPI). It allows you to create dynamic HTML pages by mixing Python-like expressions with static HTML.

When to Use Jinja2

• You want to render HTML templates on the server side.
• You’re building traditional web pages (not just APIs).
• You want to pass data from FastAPI to the frontend without writing a full SPA (like with React/Vue).

When NOT to Use Jinja2

• You’re building a pure API backend (e.g., JSON only).
• Your frontend is a separate app in React, Vue, or Angular.
• You want a client-rendered SPA with full control over rendering.

Static Files in Jinja2

In Jinja2, which is typically used with web frameworks l

ike Flask or FastAPI, static files refer to files that do not change dynamically and are sent directly to the client (browser) as-is. These include:

Common Types of Static Files:

• CSS files (style.css) — for styling your pages
• JavaScript files (main.js) — for interactivity
• Images (logo.png, background.jpg)
• Fonts and other assets
