A minimally viable toolkit designed to build Directed acyclic graphs using functional principles.
While developing Dagger, I found that it was helpful to maintain a working copy—also implemented in Go—of the fundamentals that underpinned the package due to the difficulties I encountered whilst porting the library from an untyped language.
As such, this repository holds a simplified implementation of the core behaviour for demonstration and learning purposes for both myself and anyone else that might be interested.
Before looking at the code itself, it would be useful to understand the motive behind this body of work and the scope for interesting applications that you might draw from it.
In 2019 I embarked on a personal project to deliver simple web applications using fewer over-the-air bytes than comparable emerging micro-frameworks, whos code representation (the transpiled output of JSX) offered little uniformality for compression tools to take advantage of during transmission.
It became apparent to me that by writing a factory that applied the rules of monad composition over that of the DOM API, it was possible to describe a DOM tree plainly, through a series of component (blocks of web elements) definitions that could then be further combined as one would with a traditional monad.
The result was Fui, or "Functional User Interfaces", that achieved the goal above albeit in a user-unfriendly way to some, due to the strict nature of how the framework must be used.
Applications structured this way are, by design, repetitive in their form, and more precisely mirror the structures of a tree, rather than a loose heirarchy of components and effects that one might often see in React or Angular codebase.
This naturally leads to more compression friendly code, at the cost of a dramatic concentration in the underlying framework complexity. Whether this trade-off is acceptable is up to the programmer using it, but nevertheless offers a novel alternative to the accepted norms of application development.
