spaday-trees

Trees, by Pierre, for spaday

Overview

spaday-trees wraps Pierre's imperative FileTree in a <spaday-tree> custom element and exposes it as the Python Tree component. The first release supports reactive path replacement, selected paths, search, Git status, and path-based selection-change / search-change events.

Interactive example

This app filters the tree as you type. The button changes its selected path through spaday's reactive store; selecting and expanding nodes in the tree remains client-side.

from spaday import SetField, element
from spaday.backends.starlette import serve
from spaday_trees import Tree

paths = [
    "README.md",
    "pyproject.toml",
    "src/app.py",
    "src/components/tree.py",
    "tests/test_app.py",
]

tree = (
    Tree(paths=paths)
    .bind("search", "query")
    .bind("selected_paths", "selected")
    .style(height="22rem")
)

page = (
    element("main")
    .style(max_width="42rem", margin="2rem auto", font_family="system-ui")
    .child(element("h1").text("Project files"))
    .child(
        element("input", type="search", placeholder="Filter files…")
        .bind("value", "query", mode="two-way")
        .style(width="100%", padding="0.6rem", margin_bottom="0.75rem")
    )
    .child(element("button").text("Select README").on("click", SetField("selected", ["README.md"])))
    .child(tree)
)

app = serve(page, packages=["trees"], store={"query": "", "selected": []})

Save this as app.py, then run pip install spaday-trees starlette uvicorn and uvicorn app:app. Open http://127.0.0.1:8000.

Installing this project registers the trees entry point with spaday. The equivalent explicit forms are packages=[spaday_trees.package] and packages=["spaday_trees:package"].

The integration pins @pierre/trees 1.0.0-beta.5. Rename, drag-and-drop persistence, custom composition renderers, and SSR/hydration are intentionally deferred while its beta API settles.
