HappyKit is a feature flagging solution for your Next.js applications. This is its blog with tutorials, articles and product updates around HappyKit and Next.js.

Until now I was very selective about onboarding new teams onto HappyKit. I gated the onboarding process through a manual step which required at least one interaction with me. Usually this would be an email, a Slack message or sometimes a friendly Zoom call.

That way I’ve personally talked to every team that got onboarded onto HappyKit. I learned a lot about the various ways in which people use feature flags and their pain points.

But now it’s time to open the flood gates and let everyone in, in a more automated way. That’s why today I’m making the team creation in HappyKit completely self-serve:

But of course I still love chatting to HappyKit users, so you’ll now also find a new Support button on the top right when you are signed in. This allows you to get in touch with me via email for any feedback you may have.

Happy Flagging!

It is now possible to invite your team members when using the Pro plan.

Previously Pro customers needed me to manually add their team members, but I finally got around to make this self-serve. You can now add your mates completely on your own.

Huge quality-of-life improvement: It is now possible to reorder rules.

Feature Flags can have targeting by rules. The rules allow you specify who should see which variant based on certain conditions. This is a powerful way to be very specific over which visitor is served which variant.

The rules are evaluated from top to bottom. If the first rule matches, the variant defined in that rule is served. The second rule is skipped. You can read more about this mechanism here.

Today’s addition lets you reorder the rules. This was a missing feature for too long. Reordering rules helps you adjust the order in which rules get evaluated. Just move the important ones to the top, as the evaluation runs top-to-bottom.

Previously you were able to pass persisted: true as a flag user attribute to persist the flag user. This allowed you to later see that flag user in HappyKit’s UI.

This feature was removed today and the persisted option became a no-op. The option will be removed completely in a future breaking change.

The persisted flag users feature was removed in preparation for an upcoming exciting architectural change of HappyKit.

HappyKit has a Changelog now. In fact, you’re looking at it right now!

The Changelog will contain improvements made to HappyKit. Aside from following me on Twitter, this is the best place to keep up with how HappyKit’s changes!
