1) We built our own event driven system for JS interactions. It does exactly what we want, when we want and comes in under a few thousand lines of code. The data transfer happens via a wrapper we wrote around the standard Fetch API called FetchWithTimeout (thank you David Walsh [0]). We also built our own animation library to handle things like graceful entry and exit transitions (e.g. when an item is deleted, it asynchronously swipes or fades out of view). All of this was done in vanilla JS/CSS. The only external library we used was a sub-1000 line library for toasting messages in the UI. We heavily extended this library and, hopefully, improved upon the original design. We also wrote our own CSS utility library. It's bare bones but it is exactly what we need. 2) We considered Blazor but went with MVC instead. Better suited to our skill set and definitely a bit more optimized when compared to Blazor (at least it was when we started our project). 3) We are building an internal-facing financial management system. We are heavy handed with our security approach but we have the time and the budget to be. We are in a unique situation where we have a lot of time in which to complete our project, so we can be really careful about building what we need. Also, since our application is internal, we completely bypass common user issues like browser compatibility (everyone uses the same browser) and complicated server infrastructure (we have sub 200 employees). It's a pretty fun project tbh. [0] - https://davidwalsh.name/fetch-timeout https://davidwalsh.name/fetch-timeout
