codex-fastapi-cabinet

Composable, server-rendered administration interfaces for FastAPI sites and APIs.

The library provides the management shell, routing, navigation, generic pages, dashboard widgets, permissions port, Jinja templates, and static assets. Your FastAPI application keeps ownership of authentication, authorization rules, database access, transactions, and business operations.

Status: alpha. The public API is usable, but may evolve before 1.0.

What it provides

• application-scoped admin registry;
• independent mount path, such as /cabinet or /management;
• generic list, detail, form, and operation pages;
• metric, table, list, and chart dashboard widgets;
• async application-owned data providers;
• permission checks for modules, pages, widgets, navigation, and actions;
• overridable Jinja templates and packaged responsive CSS;
• explicit module discovery without import-time registration side effects.

Quick start

from typing import ClassVar

from fastapi import FastAPI, Request

from fastapi_cabinet import (
    CabinetAdmin,
    CabinetProvider,
    CabinetSite,
    ListPage,
    ListPageMap,
    MetricWidget,
    MetricWidgetMap,
    SidebarItem,
    TableColumnMap,
    include_cabinet,
)


async def user_count(request: Request) -> MetricWidgetMap:
    return MetricWidgetMap(
        key="users-total",
        title="Users",
        value="42",
        subtitle="Registered accounts",
    )


async def user_list(request: Request) -> ListPageMap:
    return ListPageMap(
        title="Users",
        columns=[
            TableColumnMap(key="email", label="Email"),
            TableColumnMap(key="status", label="Status"),
        ],
        rows=[
            {
                "email": "admin@example.test",
                "status": "active",
                "href": "/management/users/1",
            }
        ],
        row_href_key="href",
    )


class UsersAdmin(CabinetAdmin):
    key = "users"
    label = "Users"
    sidebar = (SidebarItem(key="all", label="All users", path="all"),)
    dashboard_widgets = (
        MetricWidget(key="users-total", title="Users", provider="users.count"),
    )
    pages = (
        ListPage(key="all", label="All users", path="all", provider="users.list"),
    )
    providers: ClassVar[dict[str, CabinetProvider]] = {
        "users.count": user_count,
        "users.list": user_list,
    }


app = FastAPI()
site = CabinetSite(brand_name="My service")
site.register(UsersAdmin)
include_cabinet(app, site=site, mount_path="/management")

Run the complete example:

uvicorn examples.basic_app:app --reload

Then open http://127.0.0.1:8000/management.

Boundaries

codex-fastapi-cabinet is a composition toolkit, not an ORM-aware CRUD generator. Providers return validated view models, so the same cabinet can sit over SQLAlchemy, another database layer, an HTTP API, or an in-memory service without coupling the library to any of them.

The host application must secure the cabinet mount and provide real permission checks. The default permission provider allows every declared permission and is intended only when access control is enforced outside the library.
