Write your Own Domain Specific Language with F#
summary
Claims a practical recipe to write a strongly, statically typed DSL in F# and shows concrete tools and patterns used: Fable transpiles F# to JavaScript, units-of-measure prevent gram/kilogram mix at compile time, option and result types eliminate nulls and force explicit errors. Examples include payment and gadget types, phone/tablet code validators, and a composed workflow that goes validate -> price -> acknowledge -> events pipeline. Demonstrations compile and run, reduce runtime checks and tests, and show why nontechnical people balk at raw JSON.
