typescriptx v0.6.0

TypescriptX

Typescript Extensions for use in JavaScript/Typescript.

Principles

1. Simple ADT

TypescriptX uses simple Algebraic Data Types to encode its entities which allows you to express values with plain JavaScript objects. This makes it an excellent choice for serializing type-safe entities with a tool like lscache or redux.

2. Developer Experience

TypescriptX tries not to clutter your code, and will prefer concise decorators in an attempt to not distract readers and writers from the point of the code.

Maybe

type Maybe<A> = Just<A> | Nothing

A Maybe represents a value that can be present or null. Useful as a return type for a function that may return null.

Either

type Either<L, R> = Left<L> | Right<R>

An Either represents a value that can be one type or another. Useful as a return type for functions that can have multiple return types.

Try

export type Try<A> = Success<A> | Err

A Try represents the result of block of code that may encounter an error. Useful to encapsulate the value whose computation may throw an error.
