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

Pithy.js

An internal DSL for generating HTML in JavaScript.

Examples

Basic elements

html.div('#main', [
    html.h1(null, 'Hello, world!'),
    html.img({src: 'foo.jpg'})
]);
<div id="main">
    <h1>Hello, world!</h1>
    <img src="foo.jpg"/>
</div>

Loops etc.

Using Underscore.js or similar:

function todoItem(item) {
    return html.li({rel: item.id}, [
        html.div('.title', item.title),
        html.button('.destroy', 'delete')
    ]);
}

function todoList(list) {
    return html.ul('.todo-list', _.map(list, todoItem));
}

todoList([
    {id: 1, title: 'item one'},
    {id: 2, title: 'item two'},
    {id: 3, title: 'item three'}
]);
<ul class="todo-list">
    <li rel="1">
        <div class="title">item one</div>
        <button class="destroy">delete</button>
    </li>
    <li rel="2">
        <div class="title">item two</div>
        <button class="destroy">delete</button>
    </li>
    <li rel="3">
        <div class="title">item three</div>
        <button class="destroy">delete</button>
    </li>
</div>

Why use an internal DSL?

  • It's a more convenient and safer alternative to string contatenation
  • Very flexible, you can use all the power of JavaScript functions and control structures
  • For small bits of HTML you might not want to switch contexts form code to a template
  • Easier to debug than a templating engine
  • You get full tool-chain support:
    • editor support: syntax highlighting, code tools etc etc
    • code analyzers: jslint, jshint
    • testing/coverage tools

When to use?

  • Consider using where you might currently use string concatenation
  • Avoid using for large HTML documents or in places where speed is critical
  • Good for small snippets used for client-side page updates
  • Bad for generating huge amounts of HTML on the server

Usage

I like to alias the 'pithy' library as 'html':

var html = require('pithy');

You can then just use pithy.tagname as a function to create the appropriate element. Please note, you actually get a pithy.SafeString object back, not a native JavaScript String. This might mess up your isString() tests. If you have a workaround please send a pull-request.

There is also a pithy.escape() function for escaping HTML (returns a pithy.SafeString). It will not escape a value that is already a pithy.SafeString object.
