Blog: Implementing BFF Pattern in ASP.NET Core for SPAs

[tndata]

I just completed my 7-part blog series on implementing the Backend-for-Frontend (BFF) pattern in ASP.NET Core, taking you from building a secure BFF from scratch to replacing it with the production-ready Duende BFF library. All seven posts are now live, covering everything from cookie security and token management to enterprise-grade implementation.

Why are you calling this the Backend-for-Frontend (BFF) pattern?
The BFF name that Duende is giving it to his project is completely confusing and has nothing to do with the BFF pattern.
