Correctly publish to npm so README shows up, that’s it.

v9.3.0

Compare Source

The big new feature is an inspect method and function that allows you to “tap into” a Maybe, Result, or Task to perform side effects safely. This can be helpful for debugging, for adding tracing, or for many other similar things. For example, to debug what value exists in a chain of Maybe operations, you could use the new inspect method like this:

import type Maybe from 'true-myth/maybe';

const log = (value: unknown) => console.log("The value:", value);
const randomInteger = () => Math.floor(Math.random() * Number.MAX_SAFE_INTEGER);

const finalMaybe = Maybe.of(randomInteger())
  .inspect(log)
  .map((n) => n % randomInteger())
  .inspect(log)
  .andThen((n) => n % 2 === 0 ? Maybe.just(n / 2) : Maybe.nothing())
  .inspect(log);

For any given run, this will always log two values; it will also log a third when the modulo check passes. The output is the Maybe value.

There are also inspectErr and inspectRejected methods and functions for Result and Task instances respectively.

v9.2.0

Compare Source

Adds a flatten helper and method to each of Maybe, Result, and Task to help with the situations where you end up with a nested version of each. For example, with Maybe:

import Maybe from 'true-myth/maybe';

const wrapped = Maybe.of(Maybe.of(123));
console.log(wrapped.toString());  // Just(Just(123))

const flattened = wrapped.flatten();
console.log(flattened.toString()); // Just(123)

Note that the method or function removes only a single layer of wrapping.
