id: homepage title: Backstage homepage - Setup and Customization description: Documentation on setting up and customizing Backstage homepage Having a good Backstage homepage can significantly improve the discoverability of the platform. You want your users to find all the things they need right from the homepage and never have to remember direct URLs in Backstage. The introduces a system for composing a homepage for Backstage in order to surface relevant info and provide convenient shortcuts for common tasks. It's designed with composability in mind with an open ecosystem that allows anyone to contribute with any component, to be included in any homepage. For App Integrators, the system is designed to be composable to give total freedom in designing a Homepage that suits the needs of the organization. From the perspective of a Component Developer who wishes to contribute with building blocks to be included in Homepages, there's a convenient interface for bundling the different parts and exporting them with both error boundary and lazy loading handled under the surface. At the end of this tutorial, you can expect: Your Backstage app to have a dedicated homepage instead of Software Catalog. Understand the composability of homepage and how to start customizing it for your own organization. Before we begin, make sure You have created your own standalone Backstage app using and not using a fork of the repository. You do not have an existing homepage, and by default you are redirected to Software Catalog when you open Backstage. Now, let's get started by installing the home plugin and creating a simple homepage for your Backstage app. ```bash yarn --cwd packages/app add @backstage/plugin-home ``` Inside your `packages/app` directory, create a new file where our new homepage component is going to live. Create `packages/app/src/components/home/HomePage.tsx` with the following initial code ```tsx import React from 'react'; export const HomePage = () => ( / We will shortly compose a pretty homepage here. / <h1>Welcome to Backstage!</h1> ); ``` If you don't have a homepage already, most likely you have a redirect setup to use the Catalog homepage as a homepage. Inside your `packages/app/src/App.tsx`, look for ```tsx title="packages/app/src/App.tsx" const routes = ( <FlatRoutes> <Navigate key="/" to="catalog" /> {/ ... /} </FlatRoutes> ); ``` Let's replace the `<Navigate>` line and use the new component we created in the previous step as the new homepage. ```tsx

/ highlight-add-start / import { HomepageCompositionRoot } from '@backstage/plugin-home'; import { HomePage } from './components/home/HomePage'; / highlight-add-end / const routes = ( <FlatRoutes> {/ highlight-remove-next-line /} <Navigate key="/" to="catalog" /> {/ highlight-add-start /} <Route path="/" element={<HomepageCompositionRoot />}> <HomePage /> </Route> {/ highlight-add-end /} {/ ... /} </FlatRoutes> ); ``` Let's update the route for "Home" in the Backstage sidebar to point to the new homepage. We'll also add a Sidebar item to quickly open Catalog. | Before | After | | | | | | | The code for the Backstage sidebar is most likely inside your . Let's make the following changes ```tsx title="packages/app/src/components/Root/Root.tsx" / highlight-add-next-line / import CategoryIcon from '@material-ui/icons/Category'; export const Root = ({ children }: PropsWithChildren<{}>) => ( <SidebarPage> <Sidebar> <SidebarLogo /> {/ ... /} <SidebarGroup label="Menu" icon={<MenuIcon />}> {/ Global nav, not org-specific /} {/ highlight-remove-next-line /} <SidebarItem icon={HomeIcon} to="catalog" text="Home" /> {/ highlight-add-start /} <SidebarItem icon={HomeIcon} to="/" text="Home" /> <SidebarItem icon={CategoryIcon} to="catalog" text="Catalog" /> {/ highlight-add-end /} <SidebarItem icon={ExtensionIcon} to="api-docs" text="APIs" /> <SidebarItem icon={LibraryBooks} to="docs" text="Docs" /> <SidebarItem icon={LayersIcon} to="explore" text="Explore" /> <SidebarItem icon={CreateComponentIcon} to="create" text="Create..." /> {/ End global nav /} <SidebarDivider /> {/ ... /} </SidebarGroup> </Sidebar> </SidebarPage> ); ``` That's it! You should now have (although slightly boring) a homepage! <!-- todo: Needs zoomable plugin --> In the next steps, we will make it interesting and useful! There is a default homepage template () which we will use to set up our homepage. Checkout the about the Backstage homepage templates for more information. <!-- TODO for later: detailed instructions for using one of these templates. --> Composing a homepage is no different from creating a regular React Component, i.e. the App Integrator is free to include whatever content they like. However, there are components developed with the homepage in mind. If you are looking for components to use when composing your homepage, you can take a look at the in storybook. If you don't find a component that suits your needs but want to contribute, check the . If you want to use one of the available homepage templates you can find the in the storybook under the "Home" plugin. And if you would like to contribute a template, please see the ```tsx import React from 'react'; import Grid from '@material-ui/core/Grid'; import { HomePageCompanyLogo } from '@backstage/plugin-home'; export const homePage = ( <Grid container spacing={3}> <Grid item xs={12} md={4}> <HomePageCompanyLogo /> </Grid> </Grid> ); ```
