FAQPage Schema
How do I deploy a React and FastAPI app to Vercel?▼

Deploy a React and FastAPI app to Vercel by packaging both into a project structure with an api directory, proper routing, and a vercel.json file. This Skill automates configuring the serverless deployment to serve the SPA and APIs.

Why does my FastAPI serverless deployment lose data on cold starts?▼

FastAPI serverless deployments lose data on cold starts because serverless functions are stateless. This Skill solves this by structuring an api directory with seed data, ensuring a runnable demo with data on first run.

Can I use Vercel to host a full-stack React frontend and Python backend together?▼

Yes, you can host a full-stack React frontend and Python backend together on Vercel. This Skill packages both into a single serverless deployment using a vercel.json to route and serve the SPA and FastAPI endpoints.

Do I need the Vercel CLI installed to deploy a React and FastAPI project?▼

Yes, you need the Vercel CLI installed to deploy a React and FastAPI project using this Skill. You also need an existing project containing a frontend and backend, plus an api directory structure with seed data.

What's the best way to create a quick full-stack demo for a client pitch?▼

The best way to create a quick full-stack demo for a client pitch is deploying a React and FastAPI app to Vercel as a serverless demo. This Skill includes seeded data to ensure a runnable prototype on first run.

What are the limitations of using Vercel for a FastAPI backend?▼

A limitation of using Vercel for a FastAPI backend is that serverless functions are stateless and lose data on cold starts. This Skill mitigates this by requiring an api directory structure with seed data for runnable demos.
