# Add a shared dependency

!!!warning
This guide only applies to applications that include [remote modules](../reference/registration/registerRemoteModules.md).
!!!

[Shared dependencies](https://module-federation.io/configure/shared.html) is one of the most powerful concepts of Module Federation. However, mastering its configuration can be quite challenging. **Failure** to configure shared dependencies properly in a federated application using Module Federation can significantly **impact** both **user** and **developer experiences**.

Squide aims to **simplify** the configuration of shared dependencies by abstracting the shared dependencies necessary for building an application with React, React Router, and optionally MSW and i18next. Nevertheless, every federated application will inevitably have to configure additional custom shared dependencies.

# Use federated tabs
# Use modular tabs

While it's typically recommended for a Squide application to maintain the boundary of a page within a single domain, there are situations where **enhancing** the **user experience** necessitates rendering a page with parts from **multiple domains**, or at the very least, simulating it 😊.

For this guide, we'll take as an example a page for which the parts that are owned by different domains are organized by tabs (federated tabs):
For this guide, we'll take as an example a page for which the parts that are owned by different domains are organized by tabs (modular tabs) and registered by different modules:

- `Tab 1`: Registered by `Remote Module 1`
- `Tab 2`: Registered by `Remote Module 2`
- `Tab 3`: Registered by `Local Module`

## Define a nested layout

To build this page while adhering to Squide's constraint of avoiding hard references to elements from other modules, let's start by defining a React Router [nested layout](https://reactrouter.com/en/main/start/tutorial#nested-routes). This nested layout will handle rendering all the tab headers and the content of the active tab:

```tsx !#9-11,15 remote-module-3/src/federated-tabs-layout.tsx
```tsx !#9-11,15 remote-module-3/src/tabs-layout.tsx
import { Suspense } from "react";
import { Link, Outlet } from "react-router-dom";

export function FederatedTabsLayout() {
export function TabsLayout() {
return (
<div>
<p>Every tab is registered by a different module.</p>
<ul style={{ listStyleType: "none", margin: 0, padding: 0, display: "flex", gap: "20px" }}>
<li><Link to="federated-tabs/tab-1">Tab 1</Link></li>
<li><Link to="federated-tabs/tab-2">Tab 2</Link></li>

In the previous code sample, the `FederatedTabsLayout` component is similar to the `RootLayout` component introduced in previous guides. However, the key distinction is that this layout will be bound to the `/federated-tabs` URL path. By nesting the layout under a specific path, it will only render when the user navigates to one of the federated tab pages (e.g. `/federated-tabs/tab-1`, `/federated-tabs/tab-2`, `/federated-tabs/tab-3`).

To register the newly created layout as a nested layout, use the [registerRoute](../reference/runtime/runtime-class.md#register-routes) function:

```tsx !#7-8 remote-module-3/src/register.tsx
import type { ModuleRegisterFunction, FireflyRuntime } from "@squide/firefly";
import { FederatedTabsLayout } from "./FederatedTabsLayout.tsx";
import { TabsLayout } from "./TabsLayout.tsx";

// Register the layout as a nested layout under the "/tabs" URL path.

### Troubleshoot issues

If you are experiencing issues with this guide:

- Open the [DevTools](https://developer.chrome.com/docs/devtools/) console. You'll find a log entry for each registration that occurs and error messages if something went wrong:
- `[squide] The following route has been registered as a children of the "/federated-tabs" route.`
- `[squide] The following static navigation item has been registered to the "/federated-tabs" menu for a total of 1 item.`
- `[squide] The following route has been registered as a children of the "/tabs" route.`
- `[squide] The following static navigation item has been registered to the "/tabs" menu for a total of 1 item.`
- Refer to a working example on [GitHub](https://github.com/gsoft-inc/wl-squide/tree/main/samples/basic).
- Refer to the [troubleshooting](../troubleshooting.md) page.
