Next.js Python Templates for FastAPI and Flask

Next.js Python Templates

Video Description

In this quick introduction to Next.js Python starter templates for FastAPI and Flask, we'll explore the Vercel website and understand the concepts behind Vercel and Next.js. We'll then work through a Next.js Python template, along with its corresponding GitHub repository. Using VSCode, we'll learn how to clone and edit the starter app GitHub repo, run the Flask server, and modify the Flask API route function. Additionally, I'll point you towards valuable tutorials and documentation resources for Next.js and Vercel.

Firstly, let's introduce Vercel, a cloud platform specializing in serverless deployment and hosting for static websites and serverless functions. Then there's Next.js, a widely adopted React framework for building server-side rendered and statically generated web applications. You'll find Next.js Python templates on the Vercel website, including examples using Flask, Django, and a custom HTTP request handler based on the BaseHTTPRequestHandler class from the http.server module.

Our main focus will be on the Next.js starter templates for FastAPI and Flask. These are not just serverless functions but complete web applications. We'll concentrate on the Flask starter template, which combines Next.js frontend capabilities with Flask's backend functionality. This integration empowers you to develop full-stack web applications using React and Python.

To understand the template better, we'll explore a demo site where the Flask API is incorporated into the Next.js starter template. The Flask route decorator and route function play a crucial role in this integration. We'll examine the corresponding GitHub repository, specifically the file in the API folder, where you'll find the basic Flask Hello World example.

Returning to the Next.js Python template for Flask landing page, we'll discuss the rewrites configuration in the next.config.js file, which enables redirection of requests to the Flask API route. During development, the API requests are directed to the specific port where the Flask server is running. In production, when deploying with Vercel, the Flask server is hosted as Python serverless functions.

Now, let's clone the Flask starter repository in VSCode. Ensure you have Node.js and NPM installed. Once cloned, we'll install the project's dependencies and run the development server using the npm run dev command.

We'll access the Flask server's address in the browser, and edit the file to  modify the Flask route function.

For more information on Next.js, I recommend visiting the tutorial section on the Next.js website. It offers comprehensive learning resources starting from basic JavaScript and progressing to React and Next.js. You can check out the FastAPI documentation, and the Flask documentation, for more info on building Python APIs with FastAPI and Flask. For more information on deploying serverless functions and apps with Vercel, refer to the Vercel documentation, covering topics such as deployments, GitHub integration, custom domains, and project monitoring.

Next.js is a popular open-source framework for building web applications using React. It is built on top of React and provides a set of features and conventions that make it easier to develop scalable and production-ready applications. Next.js enables server-side rendering (SSR), static site generation (SSG), and client-side rendering (CSR), allowing developers to choose the best approach for their application's needs.

Here are some key features and benefits of Next.js:

Server-side Rendering (SSR)

Next.js allows you to render React components on the server, providing faster initial page loads and improved SEO. SSR ensures that the content is pre-rendered on the server and delivered as fully rendered HTML to the client.

Static Site Generation (SSG)

Next.js supports static site generation, where pages are pre-rendered at build time. This approach is ideal for content-focused websites that don't require real-time data. SSG provides fast and efficient performance, as the pages are served as static HTML files.

Client-side Rendering (CSR)

Next.js also supports client-side rendering, allowing components to be rendered and updated on the client-side using JavaScript. This approach is useful for dynamic and interactive parts of your application that require real-time data updates.

Automatic Code Splitting

Next.js automatically splits your JavaScript code into smaller chunks, allowing for efficient loading and rendering of pages. Only the required code for each page is loaded, optimizing performance and reducing initial load times.


Next.js provides a simple and intuitive routing system. You can define page routes easily using the file system as the API, creating a clear and organized structure for your application.

API Routes

Next.js allows you to create serverless API routes alongside your pages. You can define API endpoints to handle server-side logic and data fetching, making it easy to build backend functionality within your Next.js application.

CSS and Styling

Next.js has built-in support for CSS modules, allowing you to write modular and scoped CSS styles for your components. It also supports popular CSS-in-JS libraries like styled-components and tailwindcss.

Extensive Ecosystem

Next.js has a thriving ecosystem with a large community and extensive documentation. It integrates well with other libraries, frameworks, and tools, making it easy to leverage the existing React ecosystem.

Next.js is widely adopted by developers and companies for its simplicity, performance, and flexibility. It provides a powerful foundation for building modern web applications, whether it's a small project or a large-scale enterprise application.
