A future wrapper around a Promise.

Package Exports

  • perhaps

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (perhaps) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Overview

Extant is an implementation of SQL's COALESCE that I've used for some time to deal with the fact that JavaScript truthiness will treat '' and 0 as true so the || operator can't always be used to create given or default one-liner.

const { Future } = require('perhaps')

We use the name "perhaps" on NPM because we want the first extant argument.

Living README.md

This README.md is also a unit test using the Proof unit test framework. We'll use the Proof okay function to assert out statements in the readme. A Proof unit test generally looks like this.

require('proof')(4, async okay => {
    okay('always okay')
    okay(true, 'okay if true')
    okay(1, 1, 'okay if equal')
    okay({ value: 1 }, { value: 1 }, 'okay if deep strict equal')
})

You can run this unit test yourself to see the output from the various code sections of the readme.

git clone git@github.com:bigeasy/perhaps.git
cd perhaps
npm install --no-package-lock --no-save
node test/readme.t.js

Usage

The 'extant' module exports a single coalesce function.

const { Future } = require('perhaps')

Note that Extant is SQL's COALESCE. It returns the first non-null-like value, that is the first value that is not == null, which would be null or undefined. If there is no such argument it returns null.

okay('test')
