Tesfy Example

Tesfy allows you to create unlimited A/B Tests and Feature Flags for free using a web app or by your self.

This example shows how to integrate react-tesfy in Next.js.

To use Tesfy there are only two mandatory things needed. A userId and a configuration file known as datafile. In the _app.js you will notice that those are being get.

The userId must uniquely identify a user even if not logged in, for that reason a uuid is created and stored in a cookie so the next time a page is requested a new userId won't be created, instead the cookie one will be used.

The datafile is just a json that defines the configuration of the experiments and features avaliable. It must be fetched from Tesfy CDN or from your own servers at least everytime a request is performed, later on this configuration could also be fetched if wanted (e.g. during page transitions).
