I am working on mobile app development using react-native where I come to an issue for user registration.
In my application user can register and choose their username. Now, I want to validate the user that the user can't select any single word of the English dictionary. e.g. user can't keep the user name apple, batsman, avenger, etc. But, user can choose the combination of multiple words of the English dictionary. e.g. appleavenger, appleball, zebrahorse, etc.
Also, I want an API which can validate the user to select the name of any famous celebrity, company name, firm name as a username. e.g. users could not able to choose cocacola, pepsi, donaldtrump, barekobama etc. as their username.
So, if anyone could provide some list of APIs which I can use in my project, it would be more than good.
ThanksJD
