I have been using mysqlclient package for MySQL DB connection in Django and recently realized mysqlclient is in GPL license.
Is it fine to use mysqlclient package in a private repo for a commercial product? What I understand is that it's fine to use LGPL libraries while GPL one is not.
The GPL license effectively states that if GPL-licensed code is used in a product (either directly or pulled in through a library or package mechanism), then the whole product must comply with the terms and conditions of the GPL license.
Simply said, those terms and conditions state that every recipient of the product must be offered the source code and they must get the same modification and distribution rights as you have.
If the product does not get distributed (and in a workplace setting, that means not being distributed outside the company/legal entity that created the product), then you can do what you want.
If the product gets provided to others (for free or for a price), then you must do so under the terms and conditions of the GPL license, which means that you must offer access to your source code and you must allow your buyers to redistribute the product.
