# @soda/get-current-script 
|
|
|
|
It is basically a function that returns `document.currentScript` but with support for IE9-11, thanks to https://github.com/amiller-gh/currentScript-polyfill.
|
|
|
|
It also works around a [Firefox issue](https://bugzilla.mozilla.org/show_bug.cgi?id=1620505) when the script is called in a microtask, which makes `document.currentScript` unusable in a webpack dynamic-imported chunk.
|
|
|
|
It is shipped as a utility function rather than a polyfill, because we can't easily tell if the `document.currentScript` is returning `null` due to the Firefox issue or because it's running in an event handler / a callback.
|
|
|
|
The implementation here may not adhere strictly to `document.currentScript` spec when called in async code or in a callback. In these situations the spec calls for `document.currentScript` to return `null`. However, for the grand majority of your `document.currentScript` needs, this utility will do the job!

|
## Usage
|
|
|
|
```sh
|
|
npm i @soda/get-current-script
|
|
```
|
|
|
|
```js
|
|
const getCurrentScript = require('@soda/get-current-script')
|
|
const script = getCurrentScript() // the current executing <script> element
|
|
```
