Installation

pip install nitro-cli

AI Assistant Integration

Add Nitro CLI knowledge to your AI coding assistant:

npx skills add nitro-sh/nitro-cli

This enables AI assistants like Claude Code to understand Nitro CLI and generate correct nitro-ui code.

Quick Start

nitro new my-site
cd my-site
nitro dev

Visit http://localhost:3000. Build for production with nitro build.

Writing Pages

Pages are Python files in src/pages/ that export a render() function:

# src/pages/index.py
from nitro_ui import HTML, Head, Body, Title, Meta, H1
from nitro import Page

def render():
    return Page(
        title="Home",
        content=HTML(
            Head(
                Meta(charset="UTF-8"),
                Meta(name="viewport", content="width=device-width, initial-scale=1.0"),
                Title("Home"),
            ),
            Body(H1("Welcome!"))
        )
    )

Output paths mirror the file structure: src/pages/about.py → build/about.html

Dynamic Routes

Generate multiple pages from data using [param].py naming:

# src/pages/blog/[slug].py
from nitro import Page
from nitro_datastore import NitroDataStore

def get_paths():
    data = NitroDataStore.from_file("src/data/posts.json")
    return [{"slug": p.slug, "title": p.title} for p in data.posts]

def render(slug, title):
    return Page(title=title, content=...)
