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 🙏

@ava/babel-preset-stage-4 Build Status

Babel preset for use with AVA

Aspires to bring finished ECMAScript proposals to AVA's test and helper files.

Efficiently applies the minimum of transforms to run the latest JavaScript syntax on Node.js 8, 10 and 12.

Built-ins are not added or extended, so features like Proxies, Array.prototype.includes or String.prototype.padStart will only be available if the Node.js version running the tests supports it. Consult node.green for details.

Sometimes a particular feature is mostly implemented in Node.js. In that case transforms are not applied.

Not all proposals can be supported via Babel transforms, see below for details. Babel may require "syntax" plugins in order to parse certain files. These plugins should be applied explicitly since this preset may not include them.

Install

$ npm install --save @ava/babel-preset-stage-4

Usage

Add @ava/stage-4 to your Babel presets.

Options

For more information on setting options for a preset, refer to the preset options documentation.

modules

By default this preset transform ES2015 modules to CommonJS. Set to false to disable this behavior. Other values are ignored.

Supported proposals

| Proposal | Supported | ------------------------------------------------------------------------ | --------- | Array.prototype.includes | No | Object.values/Object.entries | No | String padding | No | Object.getOwnPropertyDescriptors | No | Trailing commas in function parameter lists and calls | Yes | Shared memory and atomics | No | Lifting template literal restriction | No | s (dotAll) flag for regular expressions | Yes | RegExp named capture groups | No | RegExp Lookbehind Assertions | No | RegExp Unicode Property Escapes | No | Promise.prototype.finally | No | Asynchronous Iteration | Partially | Optional catch binding | Yes | JSON superset | No | Symbol.prototype.description | No | Function.prototype.toString revision | No | Object.fromEntries | No | Well-formed JSON.stringify | No | String.prototype.{trimStart,trimEnd} | No | Array.prototype.{flat,flatMap} | No | String.prototype.matchAll | No | import() | Yes | Promise.allSettled | No

@babel/plugin-proposal-async-generator-functions relies on Symbol.asyncIterator, which AVA does not polyfill for you.
