Create a logo designer app using the Frame component

The app in this example showcases a logo designer and renders a preview of the designed icon within the Frame component.

The result will look like this:

This example illustrates the following:

• The integration of a Frame component into a standard UI Kit app facilitates the embedding of standard static web app resources within the UI Kit Apps. This integration also unlocks features and flexibilities that are currently exclusive to Custom UI, but not available in UI Kit.
• Establishing the communication mechanism between the UI Kit and the Frame component.
• Set up the Frame component to access and invoke the backend functions and handle asynchronous events using the Forge resolver.

If you're interested in examining the complete implementation of this app, you can clone or fork it from this repository: forge-ui-kit-frame-project-logo-designer

Before you begin

This tutorial assumes you're already familiar with the basics of Forge development. If this is your first time using Forge, see Getting started first.

Step 1: Create your app

Using your terminal complete the following:

1. Create your app by running:

   1
   2
   forge create
   

2. Enter a name for your app (up to 50 characters). For example, logo-designer.

3. Select the UI Kit category.

4. Select the Confluence Atlassian app.

5. Select the confluence-global-page template.

6. Change to the app subdirectory to see the app files:

   1
   2
   cd logo-designer
   

7. Install @forge/react version 10.2.0 or higher. To install:

   npm install --save @forge/react@latest or

   npm install --save @forge/react@^10.2.0

8. Install @forge/kvs latest version to be able to access Storage APIs:

   1
   2
   npm install @forge/kvs
   

Step 2: Create the web app resource

Prerequisites:

Make sure you've installed the most recent versions of the following:

• To verify the Node.js version, run: node --version
• To check the npm version, execute: npm --version
• To confirm the Yarn version (if applicable), type: yarn --version

To create the web app resources:

1. Create the resources folder to add static frontend app:

   1
   2
   mkdir resources
   cd resources
   

2. Create a react app:

   1
   2
   yarn create react-app project-logo-display
   

3. Setup CRA based react app to be used as Forge App based resources as described in here. Specifically, set "homepage": "./" in the resources/project-logo-display/package.json file:

   1
   2
   {
       "name": "project-logo-display",
       "version": "0.1.0",
       "private": true,
       "homepage": "./",
       ....
   }
   

4. Build assets:

   1
   2
    cd project-logo-display
    yarn build
   

Step 3: Configure the app manifest

1. In the app’s top-level directory, open the manifest.yml file.

2. Find the title entry under confluence:globalPage, and update the value to Logo Designer.

3. Create a new resource with key equals to logo-display under the resources section, and set the path pointing to the build folder of the target Frame component app as described in the previous step (i.e., resources/project-logo-display/build).

   1
   2
    resources:
    - key: main
      path: src/frontend/index.jsx
    - key: logo-display
      path: resources/project-logo-display/build
   

4. Configure the required app permissions:

   • access to the Storage API to persist the logo configurations
   • allow unsafe-inline for CSS to allow manipulating logo styles
   • allow egress access to external images

   You manifest.yml file should look like the following:

   1
   2
   modules:
     confluence:globalPage:
       - key: logo-designer-hello-world-global-page
         resource: main
         render: native
         resolver:
           function: resolver
         title: Logo Designer
         route: logo-designer
     function:
       - key: resolver
         handler: index.handler
   resources:
     - key: main
       path: src/frontend/index.jsx
     - key: logo-display
       path: resources/project-logo-display/build
   permissions:
     scopes:
       - storage:app
     content:
       styles:
         - "unsafe-inline"
     external:
       images:
         - "https://imgur.com"
         - "https://i.imgur.com"
   app:
     runtime:
       name: nodejs22.x
     id: '<your app id>'
   

Step 4: Modify the app content on the UI Kit side

1. Create the following .js files and add the following code to store the list of logo images:
   • src/frontend/constants.js
   • resources/project-logo-display/src/constants.js

1
2
export const fruitSelectionMap = [
    { name: "Avocado", url: "https://imgur.com/CIsX0ZO.png" },
    { name: "Coconut", url: "https://imgur.com/lRHQMS9.png" },
    { name: "Pear", url: "https://imgur.com/YwiIGQA.png" },
    { name: "Red Apple", url: "https://imgur.com/wduDSGD.png" },
    { name: "Orange", url: "https://imgur.com/lSyCbHI.png" },
    { name: "Pomegranate", url: "https://imgur.com/aOHoUbj.png" },
    { name: "Peach", url: "https://imgur.com/1rBCiC3.png" },
    { name: "Lemon", url: "https://imgur.com/T1s8Pts.png" },
];

2. Create the components in the UI Kit components folder (src/frontend/components), which includes:

   • src/frontend/components/BorderRadiusSlider.jsx: To adjust the border radius of the logo container.

     1
     2
     import React from "react";
     import { Stack, Text, Range } from "@forge/react";
     
     export const BorderRadiusSlider = ({ value, onChange }) => {
         return (
             <Stack space="space.200">
             <Text>Radius</Text>
             <Range
                 value={value}
                 min={0}
                 max={100}
                 onChange={onChange}
             />
             </Stack>
         );
     };
     

   • src/frontend/components/FruitIcon.jsx: To represent individual icons.

     1
     2
     import React, { useCallback } from "react";
     import { Stack, Radio, Image } from "@forge/react";
     
     export const FruitIcon = ({ name, url, isChecked, onChange }) => {
         const handleChange = useCallback((event) => {
             if (onChange) {
                 onChange(event.target.value);
             }
         }, []);
     
         return (
             <Stack alignInline="center">
                 <Image src={url} alt={name} size="xlarge" />
                 <Radio
                     name="icon"
                     value={name}
                     onChange={handleChange}
                     isChecked={isChecked}
                 />
             </Stack>
         );
     };
     

   • src/frontend/components/IconSelection.jsx: To capture logo icon selection.

     1
     2
     import React from "react";
     import { Stack, Text, Inline } from "@forge/react";
     import { FruitIcon } from "./FruitIcon";
     import { fruitSelectionMap } from "../constants";
     
     export const IconSelection = ({ value, onChange }) => {
         return (
             <Stack space="space.200">
                 <Text>Select an icon</Text>
                 <Inline shouldWrap>
                     {fruitSelectionMap.map(({ name, url }) => (
                         <FruitIcon
                             key={name}
                             name={name}
                             url={url}
                             isChecked={name === value}
                             onChange={onChange}
                         />
                     ))}
                 </Inline>
             </Stack>
         );
     };
     

3. Update the src/frontend/index.jsx file to connect the basic frontend components described above for the initial draft on the UI Kit side.

   1
   2
   import React from "react";
   import ForgeReconciler, { Inline, Stack, Heading, Frame } from "@forge/react";
   import { IconSelection } from "./components/IconSelection";
   import { BorderRadiusSlider } from "./components/BorderRadiusSlider";
   
   const App = () => {
       const [config, setConfig] = React.useState({ icon: "Avocado", radius: 20 });
       // TODO: setup logo update and preview logic
       const handleConfigChange = ({ key, value }) => {
           console.log(key, value);
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.400">
               <Heading as="h1">Project logo designer</Heading>
               <Inline space="space.400">
                   <Stack space="space.1000">
                       <IconSelection
                           value={config.icon}
                           onChange={(value) =>
                               handleConfigChange({ key: "icon", value })
                           }
                       />
                       <BorderRadiusSlider
                           value={config.radius}
                           onChange={(value) =>
                               handleConfigChange({ key: "radius", value })
                           }
                       />
                   </Stack>
                   {/* TODO: Setup logo display component */}
               </Inline>
           </Stack>
       );
   };
   
   ForgeReconciler.render(
       <React.StrictMode>
           <App />
       </React.StrictMode>
   );
   

Step 5: Modify the app content on the Frame component side

1. Start by navigating to the target Frame component project folder, which is located at resources/project-logo-display/

   1
   2
   cd resources/project-logo-display/
   

2. Add the required libraries and dependencies:

   1
   2
   yarn add @atlaskit/css-reset \
       @atlaskit/button \
       @atlaskit/primitives \
       @atlaskit/tokens \
       @atlaskit/tooltip \
       @atlaskit/visually-hidden \
       @forge/bridge \
       styled-components
   

3. Setup and initialise common frameworks and libraries (example, Atlassian Design Tokens, Styled Components) by updating the resources/project-logo-display/src/index.js file:

   1
   2
   import React from "react";
   import ReactDOM from "react-dom";
   import { createGlobalStyle } from "styled-components";
   import { view } from "@forge/bridge";
   import { token } from "@atlaskit/tokens";
   import App from "./App";
   
   import "@atlaskit/css-reset";
   
   // Enables theming
   view.theme.enable();
   
   const GlobalStyle = createGlobalStyle`
       body {
           background: ${token("elevation.surface")};
       }
       `;
   
   ReactDOM.render(
       <React.StrictMode>
           <GlobalStyle />
           <App />
       </React.StrictMode>,
       document.getElementById("root")
   );
   

4. Go to resources/project-logo-display/src/components and create the necessary components in the Frame component folder which includes:

   • resources/project-logo-display/src/components/LogoDisplay.jsx: Container to preview logo style changes.

     1
     2
     import React from "react";
     import { fruitSelectionMap } from "../constants";
     import styled from "styled-components";
     import { token } from "@atlaskit/tokens";
     
     const LogoBackground = styled.div`
         width: 280px;
         height: 280px;
         background-color: ${({ color }) =>
             color
                 ? token(`color.background.accent.${color}.subtler`)
                 : token("color.background.neutral")};
         border-radius: ${({ borderRadius }) => borderRadius}px;
     `;
     
     const iconUrls = fruitSelectionMap.reduce((acc, fruit) => {
         acc[fruit.name] = fruit.url;
         return acc;
     }, {});
     
     export const LogoDisplay = ({ icon, radius, color }) => {
         return (
             <LogoBackground borderRadius={radius} color={color}>
                 <img
                     alt="logo-img"
                     src={iconUrls[icon]}
                     style={{ width: "280px", height: "280px", display: "block" }}
                 />
             </LogoBackground>
         );
     };
     

   • resources/project-logo-display/src/components/ColorPalette.jsx: input component for capturing logo color selections.

     1
     2
     import React from "react";
     import { Inline, Pressable, xcss } from "@atlaskit/primitives";
     import Tooltip from "@atlaskit/tooltip";
     import VisuallyHidden from "@atlaskit/visually-hidden";
     
     const baseStyles = xcss({
         borderWidth: "border.width",
         borderStyle: "solid",
         borderColor: "color.border",
         borderRadius: "border.radius",
         height: "20px",
         width: "20px",
         display: "flex",
         alignItems: "center",
         justifyContent: "center",
     });
     
     const borderSelected = xcss({
         borderColor: "color.border.bold",
     });
     
     const colorMap = [
         "red",
         "orange",
         "yellow",
         "lime",
         "green",
         "teal",
         "blue",
         "purple",
         "magenta",
     ].reduce((acc, color) => {
         acc[color] = xcss({
             backgroundColor: `color.background.accent.${color}.subtler`,
             ":hover": {
                 backgroundColor: `color.background.accent.${color}.subtler.hovered`,
             },
             ":active": {
                 backgroundColor: `color.background.accent.${color}.subtler.pressed`,
             },
         });
         return acc;
     }, {});
     
     const ColorButton = ({ color, isSelected, onClick }) => {
         const pressableStyles = [baseStyles, colorMap[color]];
         return (
             <Tooltip content={color}>
                 <Pressable
                     interactionName={`color-${color}`}
                     xcss={
                         isSelected
                             ? [...pressableStyles, borderSelected]
                             : pressableStyles
                     }
                     aria-pressed={isSelected}
                     onClick={onClick}
                 >
                     <VisuallyHidden>{color}</VisuallyHidden>
                 </Pressable>
             </Tooltip>
         );
     };
     
     export const ColorPalette = ({ value, onChange }) => {
         return (
             <Inline space="space.100">
                 {Object.keys(colorMap).map((color) => {
                     return (
                         <ColorButton
                             key={color}
                             color={color}
                             isSelected={color === value}
                             onClick={() => {
                                 onChange(color);
                             }}
                         />
                     );
                 })}
             </Inline>
         );
     };
     

5. Update the resources/project-logo-display/src/App.js file to connect the basic frontend components described above for the initial draft on the Frame component side.

   You App.js file should look like the following:

   1
   2
   import React from "react";
   import { ColorPalette } from "./components/ColorPalette";
   import { LogoDisplay } from "./components/LogoDisplay";
   import { Stack } from "@atlaskit/primitives";
   
   function App() {
       const [config, setConfig] = React.useState({
           icon: "Avocado",
           radius: 20,
           color: "red",
       });
   
       const handleConfigChange = ({ key, value }) => {
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       // TODO: setup logic to track log update requests from the UI Kit side.
   
       return (
           <Stack space="space.200">
               <ColorPalette
                   value={config.color}
                   onChange={(value) =>
                       handleConfigChange({ key: "color", value })
                   }
               />
               <LogoDisplay
                   icon={config.icon}
                   radius={config.radius}
                   color={config.color}
               />
           </Stack>
       );
   }
   
   export default App;
   
   

Step 6: Set up the Frame component inside UI Kit App

Now, we are ready to include the Logo Display Frame Component into the main UI Kit app.

1. Run the following command to ensure the Frame component frontend resources are properly build and compiled.

   1
   2
   yarn build
   

2. Ensure the build artefacts are generated in the resources/project-logo-display/build folder, as this folder is linked to the resources section in the manifest.yml file.

3. In the src/frontend/index.jsx, update the UI Kit app to include the Frame component with the Frame tag with resource prop pointing to the key attribute of the target Frame resources as specified in the manifest.yml file.

   1
   2
   
   // .....
   
   const App = () => {
       const [config, setConfig] = React.useState({ icon: "Avocado", radius: 20 });
   
       // TODO: setup logo update and preview logic
       const handleConfigChange = ({ key, value }) => {
           console.log(key, value);
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.400">
               <Heading as="h1">Project logo designer</Heading>
               <Inline space="space.400">
                   <Stack space="space.1000">
                       <IconSelection
                           value={config.icon}
                           onChange={(value) =>
                               handleConfigChange({ key: "icon", value })
                           }
                       />
                       <BorderRadiusSlider
                           value={config.radius}
                           onChange={(value) =>
                               handleConfigChange({ key: "radius", value })
                           }
                       />
                   </Stack>
                   <Frame resource="logo-display" />
               </Inline>
           </Stack>
       );
   };
   
   // .....
   

Step 7: Enable communication between the UI Kit and the Frame component

You can use the Events API on @forge/bridge to communicate between the UI Kit (main app) and the Frame component. The communication mechanism is utilised in this example to enable the logo design controls (logo picker, radius slider, and so on) to modify the logo preview component within the Frame component.

1. Create the React hooks to abstract the underlying communication implementation. Copy the following hooks.js implementation into both UI Kit and Frame component sides:

   • Go to the following files, src/frontend/hooks.js and resources/project-logo-display/src/hooks.js and add the following code:

     1
     2
     import { useEffect, useState, useCallback } from "react";
     import { events } from "@forge/bridge";
     
     const LOGO_CONFIG_UPDATES_EVENT = "LOGO_CONFIG_UPDATES";
     
     export const useLogoConfigUpdates = () => {
         const [configUpdates, setConfigUpdates] = useState([]);
     
         useEffect(() => {
             const sub = events.on(LOGO_CONFIG_UPDATES_EVENT, (message) => {
                 if (
                     message &&
                     message.updates !== undefined &&
                     message.updates.length > 0
                 ) {
                     setConfigUpdates(message.updates);
                 }
             });
     
             return () => {
                 sub.then((subscription) => subscription.unsubscribe());
             };
         }, [setConfigUpdates]);
     
         const emitConfigUpdates = useCallback((updates) => {
             events.emit(LOGO_CONFIG_UPDATES_EVENT, { updates });
         }, []);
     
         return [configUpdates, emitConfigUpdates];
     };
     

2. Go to src/frontend/index.jsx to dispatch radius slider and icon selector changes from the UI Kit side.

   1
   2
   import { useLogoConfigUpdates } from "./hooks";
   
   // .....
   
   const App = () => {
       const [config, setConfig] = React.useState({ icon: "Avocado", radius: 20 });
       const [_, emitLogoConfigUpdates] = useLogoConfigUpdates();
   
       React.useEffect(() => {
           // sending through logo config updates through events API whenever
           // config object changes is detected.
           emitLogoConfigUpdates(
               Object.entries(config).map(([key, value]) => ({ key, value }))
           );
       }, [config]);
   
       const handleConfigChange = ({ key, value }) => {
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.400">
               <Heading as="h1">Project logo designer</Heading>
               <Inline space="space.400">
                   <Stack space="space.1000">
                       <IconSelection
                           value={config.icon}
                           onChange={(value) =>
                               handleConfigChange({ key: "icon", value })
                           }
                       />
                       <BorderRadiusSlider
                           value={config.radius}
                           onChange={(value) =>
                               handleConfigChange({ key: "radius", value })
                           }
                       />
                   </Stack>
                   <Frame resource="logo-display" />
               </Inline>
           </Stack>
       );
   };
   
   // .....
   
   

3. Go to resources/project-logo-display/src/App.js and listen for logo configuration updates, and adjust the logo preview within the Frame component accordingly.

   1
   2
   import React from "react";
   import { ColorPalette } from "./components/ColorPalette";
   import { LogoDisplay } from "./components/LogoDisplay";
   import { Stack } from "@atlaskit/primitives";
   import { useLogoConfigUpdates } from "./hooks";
   
   function App() {
       const [config, setConfig] = React.useState({
           icon: "Avocado",
           radius: 20,
           color: "red",
       });
   
       // track logo update requests from the UI Kit side.
       const [logoConfigUpdates] = useLogoConfigUpdates();
   
       React.useEffect(() => {
           if (logoConfigUpdates && logoConfigUpdates.length > 0) {
               // upon receiving the config updates, apply the updates to the current
               // config state to update the logo preview.
               setConfig((prevConfig) => {
                   const updatedConfig = { ...prevConfig };
                   logoConfigUpdates.forEach((update) => {
                       updatedConfig[update.key] = update.value;
                   });
                   return updatedConfig;
               });
           }
       }, [logoConfigUpdates, setConfig]);
   
       const handleConfigChange = ({ key, value }) => {
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.200">
               <ColorPalette
                   value={config.color}
                   onChange={(value) =>
                       handleConfigChange({ key: "color", value })
                   }
               />
               <LogoDisplay
                   icon={config.icon}
                   radius={config.radius}
                   color={config.color}
               />
           </Stack>
       );
   }
   export default App;
   

Step 8: Invoke backend FaaS function from Frame component

Frame component can invoke the FaaS function resources (resolvers) that are defined within its containing UI Kit App. In this example, Storage is utilised to persist and load the logo configuration, and the Storage API operations will be wrapped inside the Forge resolvers, and will be invoked from both UI Kit side and inside the Frame component.

1. Go to src/resolvers/index.js to create resolver functions for persisting and fetching logo configurations. Replace the exisitng code with the following:

   1
   2
   import Resolver from "@forge/resolver";
   import { kvs } from "@forge/kvs";
   
   const LOGO_CONFIG_STORAGE_KEY = "LOGO_CONFIG";
   
   // Move default configuration to the shared backend to remove the duplicated
   // logics in the frontend.
   const defaultLogoConfig = {
       icon: "Avocado",
       radius: 20,
       color: "red",
   };
   
   const resolver = new Resolver();
   
   resolver.define("setLogoConfig", async ({ payload: { config } }) => {
       return await kvs.set(LOGO_CONFIG_STORAGE_KEY, config);
   });
   
   resolver.define("getLogoConfig", async () => {
       let config = null;
       try {
           config = await kvs.get(LOGO_CONFIG_STORAGE_KEY);
       } catch (e) {}
       return config || defaultLogoConfig;
   });
   
   export const handler = resolver.getDefinitions();
   

2. Ensure the resolver function defined above is linked in the manifest.yml file.

   1
   2
   # file path: manifest.yml
   
   modules:
   # ...
   function:
       - key: resolve
         handler: index.handler
   

3. Go to src/hooks.js and resources/project-logo-display/src/hooks.js and add the following code to wrap the resolver functions with react hooks to enhance usability in react.

   1
   2
   import { useEffect, useState, useCallback } from "react";
   import { events, invoke } from "@forge/bridge";
   
   // ....
   
   export const useGetLogoConfigFromStorage = () => {
       const [config, setConfig] = useState(null);
   
       useEffect(() => {
           // this works in both UI Kit and inside Frame component.
           invoke("getLogoConfig").then((config) => {
               setConfig(config);
           });
       }, [setConfig]);
   
       return config;
   };
   
   export const useSetLogoConfigToStorage = () => {
       return useCallback((config) => {
           invoke("setLogoConfig", { config });
       }, []);
   };
   

4. In the src/frontend/index.jsx add the following code to set up UI Kit to load the logo configuration with storage API using the hooks defined in the previous steps.

   1
   2
   import React, { useEffect } from "react";
   import ForgeReconciler, {
       Inline,
       Stack,
       Heading,
       Frame,
   } from "@forge/react";
   import { IconSelection } from "./components/IconSelection";
   import { BorderRadiusSlider } from "./components/BorderRadiusSlider";
   import {
       useLogoConfigUpdates,
       useGetLogoConfigFromStorage,
   } from "./hooks";
   
   const LogoDesignControlPanel = ({ logoConfig: initialConfig }) => {
       const [config, setConfig] = React.useState(initialConfig);
       const [_, emitLogoConfigUpdates] = useLogoConfigUpdates();
   
       useEffect(() => {
           emitLogoConfigUpdates(
               Object.entries(config).map(([key, value]) => ({ key, value }))
           );
       }, [config]);
   
       const handleConfigChange = ({ key, value }) => {
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.400">
               <Heading as="h1">Project logo designer</Heading>
               <Inline space="space.400">
                   <Stack space="space.1000">
                       <IconSelection
                           value={config.icon}
                           onChange={(value) =>
                               handleConfigChange({ key: "icon", value })
                           }
                       />
                       <BorderRadiusSlider
                           value={config.radius}
                           onChange={(value) =>
                               handleConfigChange({ key: "radius", value })
                           }
                       />
                   </Stack>
                   <Frame resource="logo-display" />
               </Inline>
           </Stack>
       );
   };
   
   const App = () => {
       // Load the configuration from the storage API
       const logoConfig = useGetLogoConfigFromStorage();
       if (!logoConfig) {
           return null;
       }
   
       // Move the logo design control logic into a dedicated component.
       return <LogoDesignControlPanel logoConfig={logoConfig} />;
   };
   
   ForgeReconciler.render(
       <React.StrictMode>
           <App />
       </React.StrictMode>
   );
   

5. Go to resources/project-logo-display/src/App.js and add the following code to set up the Frame component to load and persist the logo configuration with storage API using the hooks defined in the previous steps.

   1
   2
   import React, { useEffect } from "react";
   import { ColorPalette } from "./components/ColorPalette";
   import { LogoDisplay } from "./components/LogoDisplay";
   import { Stack } from "@atlaskit/primitives";
   import Button from "@atlaskit/button";
   import {
       useLogoConfigUpdates,
       useGetLogoConfigFromStorage,
       useSetLogoConfigToStorage,
   } from "./hooks";
   
   const LogoDesignPanel = ({ logoConfig: initialConfig }) => {
       const [config, setConfig] = React.useState(initialConfig);
       const [logoConfigUpdates] = useLogoConfigUpdates();
       const storeLogoConfig = useSetLogoConfigToStorage();
   
       useEffect(() => {
           if (logoConfigUpdates && logoConfigUpdates.length > 0) {
               setConfig((prevConfig) => {
                   const updatedConfig = { ...prevConfig };
                   logoConfigUpdates.forEach((update) => {
                       updatedConfig[update.key] = update.value;
                   });
                   return updatedConfig;
               });
           }
       }, [logoConfigUpdates, setConfig]);
   
       const handleConfigChange = ({ key, value }) => {
           setConfig((prevConfig) => ({ ...prevConfig, [key]: value }));
       };
   
       return (
           <Stack space="space.200" alignInline="start">
               <Stack alignInline="center" space="space.200">

               </Stack>
           </Stack>
       );
   };
   
   function App() {
       // Load the configuration from the storage API
       const logoConfig = useGetLogoConfigFromStorage();
   
       if (!logoConfig) {
           return null;
       }
   
       return <LogoDesignPanel logoConfig={logoConfig} />;
   }
   
   export default App;
   

Install your app

To use your app, it must be installed onto an Atlassian site. The forge deploy command builds, compiles, and deploys your code; it'll also report any compilation errors. The forge install command then installs the deployed app onto an Atlassian site with the required API access.

1. Navigate to the app's top-level directory and deploy your app by running:

   1
   2
   forge deploy
   

2. Install your app by running:

   1
   2
   forge install
   

3. Select your Atlassian context using the arrow keys and press the enter key.

4. Enter the URL for your development site. For example, example.atlassian.net. View a list of your active sites at Atlassian administration.

Once the successful installation message appears, your app is installed and ready to use on the specified site. You can always delete your app from the site by running the forge uninstall command.

View your app

With your app installed, it’s time to see the app on a page.

1. Edit a Confluence page in your development site.
2. Type /
3. Find the macro app by name in the menu that appears and select it.
4. Publish the page.

That’s it. You now have a Forge app that renders a preview of the designed icon within the Frame component.
