Deploying Next.js with Flask

Flask and Next.js are two distinct open-source web frameworks based on Python and JavaScript, respectively, which can be used independently or integrated for enhanced functionality. The integration of Flask with Next.js can be achieved through the Next.js incremental adoption design, which allows seamless operation between a Flask API and a Next.js application using rewrites. This setup can be deployed using Nginx on an Ubuntu server, with Flask running through Gunicorn and Next.js managed by PM2 for effective process management. The combined setup enables the Next.js app to serve frontend content while the Flask API handles backend operations, thus allowing developers to leverage the strengths of both frameworks without disrupting existing APIs. Deploying this configuration simplifies future application updates and can be streamlined with CI/CD pipelines, offering a robust environment for modern web development. This approach is particularly beneficial for developers looking to evolve their applications' architecture while maintaining existing functionalities.
