FantasyLand compliant (monadic) alternative to Promises

A monad for disjunctions. (e.g.: computations that may fail)

Core combinators and higher-order functions

Turn non-concurrent FantasyLand Applicatives concurrent

A structure for representing asynchronous actions with automatic resource handling.

A structure for values that may not be available or computations that may fail.

A disjunction that's more appropriate for validating inputs with better vocabulary & straight-forward failure aggregation.

Fantasy Land Future extension of superagent

Non bloated fantasy landish functional reactive programming

An abstraction for managing asynchronous code in JS

Create futures from other async standards

Operations for asynchronous control flow.

Exalted monadic library & functional fun, fantasy-land compliant, mostly.
