Nice article, feature flagging are great, the only issue with these flags, is that in case you have really big features, it will add overhead to manage the code, it will increase the tech dept, because if you release a feature to all customers it will be meatless to have to versions of the same feature and one of them isn't called at all!
Thank you :) Yes it's true that it comes down to a cost benefit analysis. Ie, Is the use of feature flags worth the added code and overhead. It will be a case by case basis for sure and dependent on the project scope etc.
Good read. Btw I think LaunchDarkly uses Server-Sent Events (not WebSockets)
I can't believe you have to manually enable it for client-side usage. Thank you so much!
Hey Zachary, just FYI you can change this in the project setting to make flags available to the client-side by default.
In practice, we see that most users have significantly more backend flags than frontend flags. The main benefit of not sending these to the frontend are it lowers the payload size which makes everything faster.
Thanks for this great overview of LD!
