waveguide has been superseded by mikearnaldi/matechs-effect. This package is a based off a fork of waveguide, is used in production, and contains useful additional modules like a request client.

Waveguide is a set of modules provided data types for describing effects in Typescript in the fp-ts ecosystem inspired by scala projects such as ZIO and cats-effect. Waveguide allows you to communicate with the real world in a referentially transparent manner. For a quick overview of waveguide in action see the tutorial A companion streaming library is being incubated in waveguide-streams and will eventually become part of the core

IO is:

• Lazy. Work is not done until explicitly asked for and interruption can be used to stop work that is no longer needed.
• Efficient. Asynchronous boundaries only occur where necessary. The run loop will execute as much work as it can before suspending.
• Interoperable. There are a functions to adapt Promises as well as the fp-ts effect types.
• Resource safe. Exposes a number of primitives for working with resources and guaranteeing cleanup.
• Concurrent. Exposes a logical fiber model with support for joins and interrupts. Write your code as a sequence of effects and communicate with other fibers rather than trying to juggle the state of all concurrent processes at once.
