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 🙏

TeaScript

For people who don't like coffee.

This is an updated language idea with brand new syntax that is not compatible with the old TeaScript, which is no longer maintained.

Installation

Yarn

yarn add @axel669/teascript

NPM

npm i @axel669/teascript

API

const tea = require("@axel669/teascript")

const result = await tea(
    sourceCode,
    options = {
        target?: "es6" | "browser"
    }
)
if (result instanceof Error) {
    //  do something with the error
}
const { code, ast } = result

CLI Usage

Run Script

tea file <input file> <options>

Transpile File

tea file <input file> <dest file> <options>
tea file -c <input file> <options>

Transpile Directory

tea file -d <input dir> <dest dir> <options>

CLI Options

-c, -compile
Output file will be in the same dir as the source file

-d, -dir
Compile directory with output file structure mirroring source directory

-target=es6|node
Code output target. es6 will use import statements for the built-in functions,
browser will inline the built-in functions, any other value (or omitting) will
insert require calls.

Browser Usage

Include the script build/browser-tea.js on the page or use the CDN link. The browser script adds the teascript function to the global scope, and relies on the browser version of prettier.

<script src="https://unpkg.com/[email protected]/standalone.js"></script>
<script src="https://unpkg.com/[email protected]/parser-babel.js"></script>
<script src="https://cdn.jsdelivr.net/gh/axel669/[email protected]/dist/browser-tea.js"></script>

TODO

See the language ref (in the ref folder) for the future plans.
