Migrating to PRO

Migration is designed to be straightforward because the PRO editions preserve the UAParser.js API. Simply replace the package dependency and update the package name in your imports.

Every PRO edition is distributed as an @ua-parser-js-scoped package. As an example, to install the PRO Personal edition, you can use:

npm install @ua-parser-js/pro-personal

Then replace the package import in your JS code:

// Using the open-source edition
import { UAParser } from 'ua-parser-js';

// Using PRO Personal edition
import { UAParser } from '@ua-parser-js/pro-personal';

Submodule imports follow the same pattern:

import { isFrozenUA } from '@ua-parser-js/pro-personal/helpers';

License Note

PRO packages are commercial software. Only people and organizations covered by a valid license may access, install, or use them, subject to the purchased license terms. Do not share the package, npm access, or source files with unlicensed parties. A third party may use the package only as part of a product created by a valid license holder and only when the applicable license permits it.
