# WebExtension `browser` API Polyfill
|
||||
|
||||
This library allows extensions written for the Promise-based
|
||||
WebExtension/BrowserExt API being standardized by the [W3 Browser
|
||||
Extensions][w3-browserext] group to be used without modification in Google
|
||||
Chrome.
|
||||
|
||||
[w3-browserext]: https://www.w3.org/community/browserext/
|
||||
|
||||
## Basic Setup
|
||||
|
||||
In order to use the polyfill, it must be loaded into any context where
|
||||
`browser` APIs are accessed. The most common cases are background and
|
||||
content scripts, which can be specified in `manifest.json`:
|
||||
|
||||
```javascript
|
||||
{
|
||||
// ...
|
||||
|
||||
"background": {
|
||||
"scripts": [
|
||||
"browser-polyfill.js",
|
||||
"background.js"
|
||||
]
|
||||
},
|
||||
|
||||
"content_scripts": [{
|
||||
// ...
|
||||
"js": [
|
||||
"browser-polyfill.js",
|
||||
"content.js"
|
||||
]
|
||||
}]
|
||||
}
|
||||
```
|
||||
|
||||
For HTML documents, such as `browserAction` popups, or tab pages, it must be
|
||||
included more explicitly:
|
||||
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<head>
|
||||
<script type="application/javascript" src="browser-polyfill.js"></script>
|
||||
<script type="application/javascript" src="popup.js"></script>
|
||||
</head>
|
||||
<!-- ... -->
|
||||
</html>
|
||||
```
|
||||
|
||||
And for dynamically-injected content scripts loaded by `tabs.executeScript`,
|
||||
it must be injected by a separate `executeScript` call, unless it has
|
||||
already been loaded via a `content_scripts` declaration in
|
||||
`manifest.json`:
|
||||
|
||||
```javascript
|
||||
browser.tabs.executeScript({file: "browser-polyfill.js"});
|
||||
browser.tabs.executeScript({file: "content.js"}).then(result => {
|
||||
// ...
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
## Using the Promise-based APIs
|
||||
|
||||
The Promise-based APIs in the `browser` namespace work, for the most part,
|
||||
very similarly to the callback-based APIs in Chrome's `chrome` namespace.
|
||||
The major differences are:
|
||||
|
||||
* Rather than receiving a callback argument, every async function returns a
|
||||
`Promise` object, which resolves or rejects when the operation completes.
|
||||
|
||||
* Rather than checking the `chrome.runtime.lastError` property from every
|
||||
callback, code which needs to explicitly deal with errors registers a
|
||||
separate Promise rejection handler.
|
||||
|
||||
* Rather than receiving a `sendResponse` callback to send a response,
|
||||
`onMessage` listeners simply return a Promise whose resolution value is
|
||||
used as a reply.
|
||||
|
||||
* Rather than nesting callbacks when a sequence of operations depend on each
|
||||
other, Promise chaining is generally used instead.
|
||||
|
||||
* For users of an ES7 transpiler, such as Babel, the resulting Promises are
|
||||
generally used with `async` and `await`, rather than dealt with
|
||||
directly.
|
||||
|
||||
## Examples
|
||||
|
||||
The following code will retrieve a list of URLs patterns from the `storage`
|
||||
API, retrieve a list of tabs which match any of them, reload each of those
|
||||
tabs, and notify the user that is has been done:
|
||||
|
||||
```javascript
|
||||
browser.storage.get("urls").then(({urls}) => {
|
||||
return browser.tabs.query({url: urls});
|
||||
}).then(tabs => {
|
||||
return Promise.all(
|
||||
Array.from(tabs, tab => browser.tabs.reload(tab.id)));
|
||||
);
|
||||
}).then(() => {
|
||||
return browser.notifications.create({
|
||||
type: "basic",
|
||||
iconUrl: "icon.png",
|
||||
title: "Tabs reloaded",
|
||||
message: "Your tabs have been reloaded",
|
||||
});
|
||||
}).catch(error => {
|
||||
console.error(`An error occurred while reloading tabs: ${error.message}`);
|
||||
});
|
||||
```
|
||||
|
||||
Or, using an async function:
|
||||
|
||||
```javascript
|
||||
async function reloadTabs() {
|
||||
try {
|
||||
let {urls} = await browser.storage.get("urls");
|
||||
|
||||
let tabs = await browser.tabs.query({url: urls});
|
||||
|
||||
await Promise.all(
|
||||
Array.from(tabs, tab => browser.tabs.reload(tab.id)));
|
||||
);
|
||||
|
||||
await browser.notifications.create({
|
||||
type: "basic",
|
||||
iconUrl: "icon.png",
|
||||
title: "Tabs reloaded",
|
||||
message: "Your tabs have been reloaded",
|
||||
});
|
||||
} catch (error) {
|
||||
console.error(`An error occurred while reloading tabs: ${error.message}`);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
It's also possible to use Promises effectively using two-way messaging.
|
||||
Communication between a background page and a tab content script, for example,
|
||||
looks something like this from the background page side:
|
||||
|
||||
```javascript
|
||||
browser.tabs.sendMessage("get-ids").then(results => {
|
||||
processResults(results);
|
||||
});
|
||||
```
|
||||
|
||||
And like this from the content script:
|
||||
|
||||
```javascript
|
||||
browser.runtime.onMessage.addListener(msg => {
|
||||
if (msg == "get-ids") {
|
||||
return browser.storage.get("idPattern").then(({idPattern}) => {
|
||||
return Array.from(document.querySelectorAll(idPattern),
|
||||
elem => elem.textContent);
|
||||
});
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
Or vice versa.
