effective.ts

A library for writing safe, concurrent, fault-tolerant programs in TypeScript.

Key Features

• Functional design
  Effective.ts introduces an IO monad, as used in Haskell and Cats Effect (Scala). This allows the manipulation of programs as values, using pure functions. This has a "fluent" method chaining interface, to make it idiomatic to TypeScript.

• Typed errors
  The IO type tracks the possible errors which can be raised by an action, so you know exactly which error cases you need to handle. No nasty surprises!

• Concurrency and cancellation
  Launch lightweight async fibers (green threads), with support for early cancellation. Easily run actions in parallel or in sequence.

• Fault-tolerance
  In the real world, things fail, so effective.ts has built-in support for timeouts and retries with exponential backoff.
