WebExtension module: Automatically registers your `content_scripts` on domains added via `permission.request` or on `activeTab`
npm install 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-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.
How to let your users enable your extension on any domain.
You can download the standalone bundle 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';
_For Manifest v2, refer to the usage-mv2 documentation._
You need to:
- import webext-dynamic-content-scripts in the worker (no functions need to be called)optional_host_permissions
- specify in the manifest to allow new permissions to be addedcontent_scripts
- specify at least one
`js`
// example background.worker.js
navigator.importScripts('webext-dynamic-content-scripts.js');
`json`
// example manifest.json
{
"permissions": ["scripting", "storage"],
"optional_host_permissions": [":///*"],
"background": {
"service_worker": "background.worker.js"
},
"content_scripts": [
{
"matches": ["https://github.com/*"],
"css": ["content.css"],
"js": ["content.js"]
}
]
}
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 reloadcontextMenu
> - further clicks receive a moz-extension URL rather than the current page’s URL
#### 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.
