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 🙏

timediff

Calculate a time difference in several time units.

This repo is based on Marco Taubmann's work.

Usage

$ npm install @marc-maniac/timediff
import { timediff } from '@marc-maniac/timediff';

timediff('2015-01-01', '2018-05-02 02:15:10.777', 'YDHms');
// => { years: 3, days: 121, hours: 2, minutes: 15, milliseconds: 10777 }

Examples

// return the timediff in all possible units
timediff(new Date(2015, 1, 1), new Date('2018-05-02 02:15:10'));
// => { years: 3, months: 3, weeks: 0, days: 1, hours: 2, minutes: 15, seconds: 10, milliseconds: 0 }

// return the timediff only in years, weeks, days hours and seconds
timediff(new Date(2015, 1, 1), new Date('2018-05-02 02:15:10.777'), 'YWDHS');
// => { years: 3, weeks: 12, days: 6, hours: 2, seconds: 910 }

// return the timediff only in month, minutes seconds, and milliseconds
timediff(new Date(2015, 1, 1), new Date('2018-05-02 02:15:10.777'), 'MmSs');
// => { months: 39, minutes: 1575, seconds: 10, milliseconds: 777 }

// combine all options
const christmas = new Date();
christmas.setMonth(11);
christmas.setDate(24);

timediff(new Date(), christmas, {
  units: 'MWD',
  returnZeros: false,
});
// => 'Time until christmas: {"months":11,"weeks":1,"days":1}'

API

timediff(start, end, options)

Return the time difference between start and end. Use only the units specified in options.

Return:

{
  years: 0,
  months: 0,
  weeks: 0,
  days: 0,
  hours: 0,
  minutes: 0,
  seconds: 0,
  milliseconds: 0
}

start, end

Required Type: string | Date | moment

options

Type: object | string | function

Default:

{
  units: {
    years:true,
    months: true,
    weeks: true,
    days: true,
    hours: true,
    minutes: true,
    seconds: true,
    milliseconds: true
  },
  returnZeros: true,
  callback: null
}

Use timediff(start, end, unitString) (where unitString is a string) as a shortcut for timediff(start, end, {units: unitString}).

Use timediff(start, end, callback) (where callback is a function) as a shortcut for timediff(start, end, {callback: callback}).

options.units

Type: object | string

Can be an object as given above or a string containing any of YMWDHmSs. If a letter exists in the string the corresponding unit is used in the result.

| letter | result uses | | ------ | ------------ | | Y | years | | M | months | | W | weeks | | D | days | | H | hours | | m | minutes | | S | seconds | | s | milliseconds |

options.returnZeros

Type: boolean

If true result can contain fields that are 0, if false they are removed.

Pre-commit hooks

This repo uses a pre-commit hook for biome (lint & format), as well as one to enforce conventional commits.

Git hooks are scripts that run automatically every time a particular event occurs in a Git repository. These events can include committing, merging, and pushing, among others. Git hooks allow developers to enforce certain standards or checks before actions are completed in the repository, enhancing the workflow and code quality.

The pre-commit framework is a tool that leverages Git hooks to run checks on the code before it is committed to the repository. By using pre-commit, developers can configure various plugins or hooks that automatically check for syntax errors, formatting issues, or even run tests on the code being committed. This ensures that only code that passes all the defined checks can be added to the repository, helping to maintain code quality and prevent issues from being introduced.

To install the pre-commit framework on a system with Homebrew, follow these steps:

brew install pre-commit

Once pre-commit is installed, navigate to the root directory of your Git repository where you want to enable pre-commit hooks. Then, run the following command to set up pre-commit for that repository. This command installs the Git hook scripts that the pre-commit framework will use to run checks before commits.

pre-commit install --install-hooks
pre-commit install --hook-type commit-msg

The commit check will check the commit message of the first commit on your branch to check compliance with conventional commit specifications. This is important because it is used by semantic-release to determine version bumps (major, minor or patch).

Only 'feat', 'fix', 'perf', and 'revert' commits will trigger a version bump. Note that to trigger a major version bump, annotate with 'feat!'. Example commit below:

chore: Added pre-commit hook to check for conventional commit compliance (#1208)
- Moved away from mirrors-prettier, as it is now under public archive
