Vercel Flask Demo

This project demonstrates how to deploy a simple Flask web application on Vercel. It provides an example of integrating a Python backend with Vercel’s serverless platform, enabling fast and scalable deployments.

Features

• Minimal Flask app with a sample route (/)
• Vercel configuration for seamless deployment
• Quick start instructions
• Easily customizable for your own API endpoints

Getting Started

1. Clone this repository

   git clone https://github.com/rowink/flask-demo.git
   cd flask-demo

2. Install dependencies

   pip install -r requirements.txt

3. Run locally

   cd api
   flask run

   By default, Flask will serve at http://127.0.0.1:5000/.

4. Deploy to Vercel

   Click the button below to deploy your own copy to Vercel:

   

   Or, from the command line, if you have Vercel CLI:

   vercel

Customizing Your Flask App

• Modify api/index.py to add or change routes.
• Install additional Python packages as needed by adding them to requirements.txt.

Notes

• The Flask app must reside inside the api/ directory for Vercel’s Python runtime to detect it properly.
• On Vercel, each request spins up a new serverless function instance, so avoid using global state.
• For more advanced configuration, edit vercel.json as needed.
