Lazy evaluation/rendering of components The new library function mo.lazy() lets you defer the computation and rendering of components, especially useful if you have expensive components that are hidden by default (e.g., in a tab or accordion).

0.3.5

What's Changed

This release includes contributions from several contributors -- thanks @wasimsandhu , @dmadisetti , and @deepyaman!

Highlights. This release includes a new public API for programmatically running multiple apps (in run/read-only mode) -- this lets you create multi-page apps out of marimo notebooks, as well as seamlessly serve marimo apps as part of, eg, a larger FastAPI app.

Docs: https://docs.marimo.io/guides/deploying/programmatically.html

Example:

from typing import Annotated, Callable, Coroutine
from fastapi.responses import HTMLResponse, RedirectResponse
import marimo
from fastapi import FastAPI, Form, Request, Response


# Create a marimo asgi app
server = (
    marimo.create_asgi_app()
    .with_app(path="", root="./pages/index.py")
    .with_app(path="/dashboard", root="./pages/dashboard.py")
    .with_app(path="/sales", root="./pages/sales.py")
)

# Create a FastAPI app
app = FastAPI()

app.add_middleware(auth_middleware)
app.add_route("/login", my_login_route, methods=["POST"])

app.mount("/", server.build())

# Run the server
if __name__ == "__main__":
    import uvicorn

    uvicorn.run(app, host="localhost", port=8000)

What's Changed

Highlights

Automatic package discovery and installation. marimo now automatically detects when you're missing packages in your Python environment, and gives you the option to install them using pip, uv, or rye. When installation is successful, cells depending on the packages are automatically re-run!

marimo will alert you to missing packages:

and keeps you updated on installation progress:

This feature makes it really easy to get started with new notebooks and projects, especially when working in a fresh Python environment: just install packages as you go!

Visualize arrays and matrices with mo.image()! mo.image() can now visualize NumPy arrays, torch Tensors, and Scipy sparse matrices as images.
