# Deprecation: #100014 - Function `getParameterFromUrl()` of `@typo3/backend/utility` module {#deprecation-100014-1677078784}

See [forge#100014](https://forge.typo3.org/issues/100014)

## Description {#description}

The function `getParameterFromUrl()` of the `@typo3/backend/utility`
module was used to obtain a query string argument from an arbitrary URL.
Meanwhile, browsers received the [URLSearchParams API](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) that can be used
instead.

Therefore, `getParameterFromUrl()` has been marked as deprecated.

## Impact {#impact}

Calling `getParameterFromUrl()` will trigger a deprecation warning.

## Affected installations {#affected-installations}

All installations using third-party extensions relying on the deprecated code are
affected.

## Migration {#migration}

Migrate to the following snippet to get the same result:

```javascript
const paramValue = new URL(url, window.location.origin).searchParams.get(parameter);
```
