To configure your boilerplate files to inject JavaScript onto an existing webpage with a Chrome extension, you will need to follow these steps:

1. Create a background.js file in your extension's main folder.

2. In background.js, add the code to inject the JavaScript file onto the page:
```javascript
chrome.webNavigation.onCompleted.addListener(function(details) {
  const tabId = details.tabId;
  chrome.tabs.executeScript(tabId, {
    file: 'inject.js',
  });
});
```
3. Include the following code in manifest.json to enable the background.js file:
```json
  "background": {
    "service_worker": "background.js"
  },
```
4. Add a folder called "content_scripts" to your extension's main folder.
5. Create a file called "inject.js" in the "content_scripts" folder.
6. Add your JavaScript code to the "inject.js" file.
7. In manifest.json, add the following code under "content_scripts":
```json
  "content_scripts": {
    "matches": ["<all_urls>"],
    "js": [
      "inject.js"
    ],
    "run_at": "document_start"
  },
```

This will run the JavaScript file on every page visited.

Note: Make sure to include the necessary permissions in manifest.json to access relevant web APIs.

To configure a Chrome extension to inject JavaScript on an existing webpage, follow these steps:

1. Create a new Chrome extension project using the Chrome Developer Tools (DevTools) or a tool like Visual Studio Code with the Chrome Extension Development (CED) extension.

2. In your extension's folder, create a new folder called "manifest.json" and add a file named "manifest.json" inside it. This file is the main configuration file for your extension.

3. In "manifest.json", add the following properties to enable content scripts:

   ```json
   {
     "name": "My Extension",
     "version": "1.0",
     "manifest_version": 3,
     "permissions": ["activeTab", "tabs"],
     "browser_action": {
       "default_icon": "icon.png"
     },
     "content_scripts": [
       {
         "matches": ["<URL_OF_THE_PAGE_TO_INJECT_SCRIPT>"],
         "js": ["inject.js"]
       }
     ]
   }
   ```

   Replace `<URL_OF_THE_PAGE_TO_INJECT_SCRIPT>` with the URL of the webpage you want to inject your JavaScript into.

4. Create a new file named "inject.js" in your extension's root folder. This file will contain your JavaScript code to be injected into the webpage.

5. In "inject.js", add your desired JavaScript code. For example, to log a message to the console, you could add:

   ```javascript
   console.log("My extension is running!");
   ```

6. Save both "manifest.json" and "inject.js" files.

7. To test your extension, follow these steps:

   a. Open Chrome and navigate to chrome://extensions.
   b. Enable Developer Mode (toggle the switch at the top right).
   c. Click "Load unpacked extension" and select the root folder of your extension.
   d. Visit the webpage you specified in "manifest.json".

   If everything is set up correctly, your JavaScript code should be injected into the webpage, and you should see the console message in the Chrome DevTools console.

Note: If you're using a different version of the Chrome extension manifest (e.g., manifest_version: 2), the syntax for content scripts may differ slightly. Refer to the Chrome Extension documentation for more information.
