README
# webext-dynamic-content-scripts [](https://www.npmjs.com/package/webext-dynamic-content-scripts)
> WebExtension module: Automatically registers your `content_scripts` on domains added via `permissions.request`
- Browsers: Chrome, Firefox, and Safari
- Manifest: v2 and v3
This module will automatically register your `content_scripts` from `manifest.json` into new domains granted via `permissions.request()`, or via [webext-domain-permission-toggle](https://github.com/fregante/webext-domain-permission-toggle).
The main use case is ship your extension with a minimal set of hosts and then allow the user to enable it on any domain; this way you don't need to use a broad `` permission.
## Guides
[**How to let your users enable your extension on any domain.**](how-to-add-github-enterprise-support-to-web-extensions.md)
## Install
You can download the [standalone bundle](https://bundle.fregante.com/?pkg=webext-dynamic-content-scripts) and include it in your `manifest.json`. Or use npm:
```sh
npm install webext-dynamic-content-scripts
```
```js
// This module is only offered as a ES Module
import 'webext-dynamic-content-scripts';
```
## Usage
_For Manifest v2, refer to the [usage-mv2](./usage-mv2.md) documentation._
You need to:
- import `webext-dynamic-content-scripts` in the worker (no functions need to be called)
- specify `optional_host_permissions` in the manifest to allow new permissions to be added
- specify at least one `content_scripts`
```js
// example background.worker.js
navigator.importScripts('webext-dynamic-content-scripts.js');
```
```json
// example manifest.json
{
"permissions": ["scripting"],
"optional_host_permissions": ["*://*/*"],
"background": {
"service_worker": "background.worker.js"
},
"content_scripts": [
{
"matches": ["https://github.com/*"],
"css": ["content.css"],
"js": ["content.js"]
}
]
}
```
### `activeTab` tracking
By default, the module will only inject the content scripts into newly-permitted hosts, but it will ignore temporary permissions like `activeTab`. If you also want to automatically inject the content scripts into every frame of tabs as soon as they receive the `activeTab` permission, import a different entry point **instead of the default one.**
```js
import 'webext-dynamic-content-scripts/including-active-tab.js';
```
> **Note**
> This does not work well in Firefox because of some compounding bugs:
> - `activeTab` seems to be lost after a reload
> - further `contextMenu` clicks receive a moz-extension URL rather than the current page’s URL
### Additional APIs
#### `isContentScriptRegistered(url)`
You can detect whether a specific URL will receive the content scripts by importing the `utils` file:
```js
import {isContentScriptRegistered} from 'webext-dynamic-content-scripts/utils.js';
if (await isContentScriptRegistered('https://google.com/search')) {
console.log('Either way, the content scripts are registered');
}
```
`isContentScriptRegistered` returns a promise that resolves with a string indicating the type of injection (`'static'` or `'dynamic'`) or `false` if it won't be injected on the specified URL.
