USE CASE 1

Add API endpoints and server-side logic to an existing Vite frontend without creating a separate backend project.

USE CASE 2

Deploy the same Vite app to different cloud platforms or edge runtimes without rewriting server config each time.

USE CASE 3

Bundle a full-stack Vite project into a single deployable package for production.

In plain English

Nitro is a TypeScript toolkit that adds a server layer to Vite-based web applications. If you have a frontend built with Vite (a popular tool for building websites), Nitro gives it a matching backend server that is ready for real-world use without requiring custom configuration. The goal is to bridge the gap between a frontend project and the server infrastructure needed to run it in production. The main draw is deployment flexibility. Nitro is built to run across many different hosting platforms, so you are not locked into a single provider. If you prefer a major cloud service, an edge runtime, or a self-managed server, Nitro is designed to adapt to those environments without much friction. Nitro also lets developers define server routes, which means you can add API endpoints or server-side logic alongside your existing Vite frontend. This keeps backend and frontend code in the same project, reducing the number of separate services you need to manage. The project describes itself as zero-config, meaning you can add it to a Vite project and it starts working without a lengthy setup process. The toolkit aims to handle common server concerns such as bundling, routing, and deployment packaging, so the developer can focus on writing application logic. At the time of writing, the repository's v3 branch is under active development. The stable release lives on the v2 branch. The project is MIT-licensed and full documentation is available at nitro.build. The README for this repository is short and does not describe the full feature set in detail.

Copy-paste prompts

Prompt 1
I have a Vite frontend and want to add API routes using Nitro. Show me how to define a simple GET /api/hello endpoint and return JSON.
Prompt 2
How do I configure Nitro to deploy my Vite app to a serverless edge platform? Show a minimal nitro.config.ts example.
Prompt 3
Using Nitro, how do I handle a POST request from my Vite frontend, parse the JSON body, and return a response?
Prompt 4
What is the difference between Nitro v2 stable and v3 in development and which should I use for a new Vite project today?
