Integrate WebToNative SDK into Your Base 44 React App

Step 1: Open Your Base44 App

• Go to base44.com and log in.

• On the left sidebar, click on Apps to scroll through all your apps.

• Choose an app (e.g., a template of TaskFlow, which you have cloned). There will be a card with the name of your app, description, and date of creation.

Step 2: Access the Code Editor

• With your app open, in the top navigation bar or sidebar, look for the Code Icon, which will look like </> or a code bracket.

• Click on it to open the code view.

• In the Code Panel, click on See all Codes or See all Files to expand the entire file structure, such as pages, components, and entities.

Note: In case you are editing the code under the free plan, you will be directed to the paid plan. Update your plan and restart.

Step 3: Find and make changes to the Root Layout File.

• In the left panel, you will see the File Tree. You have to expand the pages or the root file if it is flattened.

• Click on layout.js or Layout.js. This is your main layout file, often at the project root, where you can add the scripts and make sure that they will run in all cases.

• It should look like a file with imports from React and other components.

• The layout.js content will be displayed in the Code Editor (right panel). Move to the bottom, which is the last open brace }, before the statement that is the export statement.

Step 4: Insert WebToNative (WTN) Script Snippet.

• Insert the following snippet given below at the end of the file within the main function (after any existing useEffect or logic, but before the return statement).

• In case there is no useEffect, then add it immediately after the declaration of the functions.

  ```javascript
   import { useEffect } from 'react';  // Add this import at the top if it's not already there
   import { useEffect } from 'react';  // Add this import at the top if it's not already there

   // ... (rest of your existing code)

   export default function Layout({ children, currentPageName }) {
     // ... (any existing useEffect or logic here)

     useEffect(() => {
       (function() {
         // WebToNative SDK URL
         const SDK_URL = "https://unpkg.com/webtonative@1.0.77/webtonative.min.js";

The SDK URL in the useEffect snippet points to version 1.0.77. Always check the WebToNative Documentation for the latest version and replace the URL (e.g., update @1.0.77 to the newest tag) before pasting, ensuring compatibility and security.

         // Idempotent loading - does not load if it already exists
         if (document.getElementById("wtn-sdk")) {
           console.log('[WTN] ???? SDK already loaded');
           return;
         }
         
         const script = document.createElement("script");
         script.id = "wtn-sdk";
         script.src = SDK_URL;
         script.async = true;
         
         script.onload = function() {
           console.log('[WTN] ✅ SDK loaded successfully!');
           
           if (window.WTN) {
             console.log('[WTN] ⚙️ SDK initialized');
           }
         };
         
         script.onerror = function() {
           console.warn('[WTN] ⚠️ Failed to load SDK (normal in web browser)');
         };
         
         document.head.appendChild(script);
       })();
     }, []);

     // ... (your return statement and closing brace)
   }

Quick Tips

• Copy the above snippet exactly.

• In case there is already an import of useEffect, then do not include it.

• Make sure it is appropriately indented for your file format.

• Save the file (Base44 will save automatically, but in case it prompts, save your file).

Step 5: Preview and Test Your App.

• On the top bar, click on Preview to see your app function.

• Open your browser's Developer Tools (right-click > Inspect > Console tab) to check for logs like `[WTN], SDK loaded successfully!. This confirms it's working.

Step 6: Publish Your Changes

• Finally, when you are just done with your changes, click Publish in the upper right side to make the updates live.

• Share your app link to testers or export (e.g., ZIP, GitHub, or through the beta features).

Next Steps

• Explore WTN Options: Once you have made the integration, embark on using the window.WTN within your own code for native calls (e.g. WTN.openUrl(‘https://example.com’)).

• Customise: It is possible that your app has a different layout file, so add the script there.
