Fluture is a Fantasy Land compliant, monadic alternative to JavaScript Promises, representing asynchronous operations as lazy, composable Futures. It provides cancellation, resource management, stack-safe composition, and Sanctuary integration.

Use cases

• replace promises with lazy cancellable async computations
• compose asynchronous operations monadically in JavaScript
• manage async resources with safe acquisition and release
• avoid stack overflows in deep async recursion
• integrate async control flow with Sanctuary and Fantasy Land

When to choose

• you want lazy, cancellable async control flow instead of eager Promises
• you work in a functional programming style and need monadic composition
• you need stack-safe recursion and resource management for async I/O

When to avoid

• you just need simple promise-based async and don't want functional programming concepts
• your team is unfamiliar with monads and algebraic data types
• you need a widely maintained library with frequent updates
