Squide Framework

Squide is a React modular application shell. Use only documented APIs.

Core Concepts

• Runtime: The FireflyRuntime instance is the backbone of a Squide application. Never instantiate directly — use initializeFirefly(), which wires up plugins, logging, and the module lifecycle.
• Modular Registration: Modules register routes, navigation items, and MSW handlers via a registration function, assembled by the host at bootstrapping.
• Public vs Protected Routes: Routes default to protected (rendered under ProtectedRoutes). Use registerPublicRoute() for public routes. Protected routes fetch both public and protected global data.
• Deferred Registrations: Navigation items dependent on remote data or feature flags use two-phase registration — return a function from the registration to defer items to a second phase.

Key Patterns

Host Application Setup

// host/src/index.tsx
import { createRoot } from "react-dom/client";
import { FireflyProvider, initializeFirefly } from "@squide/firefly";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";
import { App } from "./App.tsx";
import { registerHost } from "./register.tsx";

const runtime = initializeFirefly({
    localModules: [registerHost]
});

const queryClient = new QueryClient();
const root = createRoot(document.getElementById("root")!);

root.render(
    <FireflyProvider runtime={runtime}>
        <QueryClientProvider client={queryClient}>
            <App />
        </QueryClientProvider>
    </FireflyProvider>
);

// host/src/App.tsx
import { AppRouter, useIsBootstrapping } from "@squide/firefly";
import { createBrowserRouter, Outlet } from "react-router";
import { RouterProvider } from "react-router/dom";

function BootstrappingRoute() {
    if (useIsBootstrapping()) {
        return <div>Loading...</div>;
    }
    return <Outlet />;
}

export function App() {
    return (
        <AppRouter>
            {({ rootRoute, registeredRoutes, routerProps, routerProviderProps }) => (
                <RouterProvider
                    router={createBrowserRouter([{
                        element: rootRoute,
                        children: [{
                            element: <BootstrappingRoute />,
                            children: registeredRoutes
                        }]
                    }], routerProps)}
                    {...routerProviderProps}
                />
            )}
        </AppRouter>
    );
}

// host/src/register.tsx
import { PublicRoutes, ProtectedRoutes, type ModuleRegisterFunction, type FireflyRuntime } from "@squide/firefly";
import { RootLayout } from "./RootLayout.tsx";

export const registerHost: ModuleRegisterFunction<FireflyRuntime> = runtime => {
    runtime.registerRoute({
        element: <RootLayout />,
        children: [PublicRoutes, ProtectedRoutes]
    }, { hoist: true });

    // HomePage and NotFoundPage are local page components
    runtime.registerRoute({ index: true, element: <HomePage /> });
    runtime.registerPublicRoute({ path: "*", element: <NotFoundPage /> });
};

Navigation Rendering

Important: RenderItemFunction signature is (item, key, index, level) => ReactNode and RenderSectionFunction is (elements, key, index, level) => ReactNode. These signatures are fixed and do not accept custom context parameters, but there could be fewer arguments. Use closures to access external values.

import { Link, Outlet } from "react-router";
import {
    useNavigationItems, useRenderedNavigationItems, isNavigationLink,
    type RenderItemFunction, type RenderSectionFunction
} from "@squide/firefly";

// Signature: (item, key, index, level) => ReactNode
const renderItem: RenderItemFunction = (item, key, index, level) => {
    if (!isNavigationLink(item)) return null;
    const { label, linkProps, additionalProps } = item;
    return (
        <li key={key}>
            <Link {...linkProps} {...additionalProps}>{label}</Link>
        </li>
    );
};

// Signature: (elements, key, index, level) => ReactNode
const renderSection: RenderSectionFunction = (elements, key, index, level) => (
    <ul key={key}>{elements}</ul>
);

export function RootLayout() {
    const navigationItems = useNavigationItems();
    const navigationElements = useRenderedNavigationItems(navigationItems, renderItem, renderSection);
    return (
        <>
            <nav>{navigationElements}</nav>
            <Outlet />
        </>
    );
}

Global Data Fetching

// Protected data
import { useProtectedDataQueries, useIsBootstrapping, AppRouter } from "@squide/firefly";

// ApiError and isApiError are app-specific; define them to match your API's error shape
function BootstrappingRoute() {
    const [session] = useProtectedDataQueries([{
        queryKey: ["/api/session"],
        queryFn: async () => {
            const response = await fetch("/api/session");
            if (!response.ok) throw new ApiError(response.status);
            return response.json();
        }
    }], error => isApiError(error) && error.status === 401);

    if (useIsBootstrapping()) return <div>Loading...</div>;

    return (
        <SessionContext.Provider value={session}>
            <Outlet />
        </SessionContext.Provider>
    );
}

// In App component, set waitForProtectedData
<AppRouter waitForProtectedData>...</AppRouter>

// Public data
const [data] = usePublicDataQueries([{ queryKey: [...], queryFn: ... }]);
<AppRouter waitForPublicData>...</AppRouter>

Deferred Navigation Items

export const register: ModuleRegisterFunction<FireflyRuntime, unknown, DeferredRegistrationData> = runtime => {
    // Always register routes
    runtime.registerRoute({ path: "/feature", element: <FeaturePage /> });

    // Return function for deferred navigation items
    return (deferredRuntime, { userData }) => {
        if (userData.isAdmin && deferredRuntime.getFeatureFlag("enable-feature")) {
            deferredRuntime.registerNavigationItem({
                $id: "feature",
                $label: "Feature",
                to: "/feature"
            });
        }
    };
};

// Execute deferred registrations in BootstrappingRoute.
// Wrap in useMemo — without it, a new object reference each render re-triggers all deferred registrations.
const data = useMemo(() => ({ userData }), [userData]);
useDeferredRegistrations(data);

Common Pitfalls

Skill maintainers: Before updating this skill, read ODR-0008. The body must stay under ~250 lines; new API content goes in the appropriate references/ file.

When working with Squide APIs, watch for these common mistakes:

1. useRenderedNavigationItems function signatures: Must always be (item, key, index, level) and (elements, key, index, level). These do NOT accept custom context parameters. If external values are needed (route params, location, etc.), use closures or React hooks - never suggest adding parameters to these functions.
2. Active state styling: Use React Router's NavLink and its isActive argument provided to the className/style render functions (for example, className={({isActive}) =>...}). Do not suggest passing location/pathname as a context parameter.
3. Dynamic route segments: Use the resolveRouteSegments helper with closures to capture values like userId. Example pattern: create a higher-order function that returns a RenderItemFunction.
4. Deferred registration runtime parameter: The deferred registration callback receives deferredRuntime as its first argument — this is NOT the same runtime from the outer registration function. Always use deferredRuntime inside the deferred callback for registerNavigationItem, getFeatureFlag, etc.
