Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@obsidize/semver

Middleware to compare semver strings and not cause error explosions on malformed input.

This was created with the belief that a version comparator should not halt execution during other complex processes.

import * as compareVersions from 'compare-versions';
import {Semver} from '@obsidize/semver';

compareVersions('1.2.3', ''); // ERROR ERROR ERROR ONE OF THE ARGS ISN'T A VERSION AHHHHH!!!
Semver.greaterThan('1.2.3', ''); // false

NOTE: While the above example is poking fun at the compare-versions module, this module actually uses compare-versions as the primary backend for core comparison logic.

Installation

  • npm:
npm install --save @obsidize/semver
  • git:
npm install --save git+https://github.com/jospete/obsidize-semver.git

Usage

Example

import {Semver, SemverComparator, SemverContext} from '@obsidize/semver';

// Use the static comparator for one-off comparisons
console.log(Semver.gt('1.2.3', '1')); // true
console.log(Semver.gt('1.2.3', null)); // false
console.log(Semver.eq('1.2.3', null, true)); // true (because 3rd parameter 'defaultValue' is true)

// Or create a version context for multiple checks against a target version
const version = new SemverContext(() => '1.2.3'); // or load this dynamically from somewhere else
console.log(version.lt('2')); // true
console.log(version.eq('1.2.3')); // true
console.log(version.gte('1.2.3')); // true
console.log(version.gt(null)); // false
console.log(version.gt(null, true)); // true
console.log(version.gt('2', true)); // false

// Don't like 'compare-versions' as the backend?
// Make your own!
const customComparator = new SemverComparator((a, b) =>  /* fancy compare function here */);

See the Example Usage Spec to get a general feel for what this module can do.
