# How to check the version of the SDK I am currently using?

There are multiple ways to check the version currently being used -

- The first way is to use the [version API](https://www.dynamsoft.com/barcode-reader/docs/web/programming/javascript/api-reference/barcode-reader-module-class.html#getversion). Using this API in the browser console should print out the version of the library being used by the web app.
- If you are using the library via npm or yarn, then you can check the installed version of the package via `npm list`. Note that the npm package has been renamed across major versions:
    - Version 11 and above: `npm list dynamsoft-barcode-reader-bundle`
    - Version 10: `npm list dynamsoft-barcode-reader`
    - Version 9: `npm list dynamsoft-javascript-barcode`

- If you are including the library via the CDN link, then the version number should be mentioned in that reference link.
