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 🙏

html-compose

Static HTML builder with component-style includes, props and watch mode.

Build modular HTML pages using reusable components without a framework.

You can split HTML into components and compose pages with:

  • include() for components
  • props for passing data
  • iff() for conditional rendering
  • watch mode for automatic rebuilding

Installation

Install in your project:

npm install html-compose

Usage

Build a directory:

html-compose src dist

Watch mode:

html-compose src dist --watch

Example package.json scripts:

{
  "scripts": {
    "build:html": "html-compose src dist",
    "watch:html": "html-compose src dist --watch"
  }
}

Run with:

npm run watch:html

Example Project Structure

src/
  index.html
  about.html

  _components/
    header.html
    footer.html
    card.html

Files and folders starting with _ are treated as private templates.

They are not rendered as standalone pages, but can be included inside other HTML files.

Include Components

${ await include('./_components/header.html') }

Components can be nested and reused across multiple pages.

Passing Props

Props can be passed into components.

Page

${ await include('./_components/card.html', {
  title: 'Hello',
  text: 'Welcome to the site'
}) }

Component

<div class="card">
  <h2>${ props.title }</h2>
  <p>${ props.text }</p>
</div>

Conditional Rendering

Use iff() for conditional rendering.

${ iff(props.loggedIn, `
  <p>Welcome back!</p>
`) }

With an else case:

${ iff(props.loggedIn,
  `<p>Welcome!</p>`,
  `<p>Please log in</p>`
) }

Watch Mode

Watch mode automatically rebuilds when HTML files change.

html-compose src dist --watch

Example output:

[html-compose] built index.html
[html-compose] built about.html
[html-compose] watch mode

Private Templates

Any file or directory starting with _ is not rendered as a page.

Example:

src/
  index.html
  _components/
    header.html
    footer.html

Output:

dist/
  index.html

But components can still be used via include().

Example Page

<body>

${ await include('./_components/header.html', {
  title: "My Site"
}) }

<main>
  <h1>Hello</h1>
</main>

${ await include('./_components/footer.html') }

</body>

How It Works

The build pipeline:

HTML files
   ↓
include()
   ↓
props
   ↓
iff()
   ↓
render
   ↓
dist output

Templates are rendered using a JavaScript-based template engine internally.

Roadmap

Possible future features:

  • each() loops
  • dependency graph for faster watch rebuilds
  • HTML minification
  • layouts
  • plugin system
