From Chaos to Clarity Mathematical Foundations for Maintainable React Applications
summary
Models a codebase as a file-import graph (nodes = files, edges = imports) and extracts concrete metrics: cycle detection via DFS to avoid bundle failures and stack overflows, community detection (Lin method) and centrality scores to produce deterministic module boundaries, refactoring priorities and test targets, and density to flag “spaghetti” hotspots. Uses Category Theory primitives—functors and monads plus lenses and transducers—to eliminate mutation and chain safe transformations; applies currying, memoization, trampolines and lazy evaluation from lambda calculus. An open‑source tool called code Health met generates the reports and guides successful refactors.
