immutable-async v0.5.1

immutable-async

asynchronous bindings for immutable.js

immutable-async makes using async/await syntax with Immutable's intuitive chaining syntax not only possible, but very simple. With immutable-async, the way to achieve this is very simply like below:

const mapped = await Seq(collection).async().map(asyncMappingFunction.sync()

Currently, this functionality is only implemented for Seq. However, going forward, this will be eventually implemented for all implemented Immutable objects.

How it works

immutable-async uses a hook to override the implementation of Immutable objects to inject an "async" function into them, which returns a handle to an object which can chain asynchronous functions for processing. This object contains a sync() function which returns the Promise whose result will be the processed object in the form of the original Immutable type.
