ts-experiments

A small collection of Typescript experiments

Contents

• Workflows/Sagas -- musings on a workflow framework for microservices influenced by talk "Data Consistency in Microservice Using Sagas"
• Deferred Computations -- a number of utilities for deferring computations, including
  • Pr, a Promise-like data type for sync/async computations conforming to Monad laws
  • Cat's-like Eval data structure for sync computations
  • various trampoliners with optional caching
• eDSL experiments -- various experiments with eDSLs, tagged and tagless, and transformations between them
  • "Building eDSLs in functional TypeScript" workshop files -- implementation directed by Yuri Bogomolov's workshop
  • Extendable eDSLs -- implementation of tagged extendable eDSLs for basic arithmetics along with some pitfalls. A more typesafe version than Arithmetics below
  • Arithmetics -- a playground for tagged and tagless representation of basic arithmetics
  • Handlers eDSL -- musings on eDSLs that have both creation-time and execution-time dependencies (e.g. DB operations that require a connection/client/transaction object for each operation); tldr: use ReaderTaskEither
