Conclusion
I have looked at two patterns here. The first is shaping up to be the Internet’s go to option. Most of us are becoming familiar with the pattern and expect the APIs we work in the same way. However, what I have witnessed is that most development teams are not ready for the kind of discipline that is required for API versioning. This will probably need to change in future, and in your development team, you should be thinking about this problem – especially if you are considering mobile app development, or public API deployment. The BFF pattern might give you a bit of wiggle room when you have a tight deadline, but it’s not a very good long term solution. If you’re looking at deploying to the app store, you should look at alternative deployment options like Apple Developer Enterprise Program, and Google Play for enterprises. I will add more on these in subsequent articles.
