Why use this

We support certain browsers (the main ones) and would like to inform users gently that they aren't supported and things may not work. This doesn't block access. This doesn't hinder the users experience. Simply states that unless they move to a supported browser, we can't guarantee a good user experience.

This helps manage expectations for users as well as aids in our support center in diagnosing issues.


browserInfo - This is the library which obtains all the information. Its in its own file if you just want to gather the data.

supportedBrowser - This is just a simple function. Given what you want and what the user has will output basic booleans to act upon.
