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.
