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 🙏

hast utility to check if a link element is “body OK”.

Contents

What is this?

This package is a utility that, when given a hast node, checks whether it is a “body OK” link.

When should I use this?

You can use this package to check whether links can exist inside <body> (outside of <head>).

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install hast-util-is-body-ok-link

In Deno with esm.sh:

import {isBodyOkLink} from 'https://esm.sh/hast-util-is-body-ok-link@3'

In browsers with esm.sh:

<script type="module">
  import {isBodyOkLink} from 'https://esm.sh/hast-util-is-body-ok-link@3?bundle'
</script>

Use

import {h} from 'hastscript'
import {isBodyOkLink} from 'hast-util-is-body-ok-link'

isBodyOkLink(h('link', {itemProp: 'foo'})) //=> true
isBodyOkLink(h('link', {rel: ['stylesheet'], href: 'index.css'})) //=> true
isBodyOkLink(h('link', {rel: ['author'], href: 'index.css'})) //=> false

API

This package exports the identifier isBodyOkLink. There is no default export.

isBodyOkLink(node)

Check whether a node is a “body OK” link.

The following nodes are “body OK” links:

  • link elements with an itemProp
  • link elements with a rel list where one or more entries are pingback, prefetch, or stylesheet
Parameters
  • node (Node) — node to check.
Returns

Whether a node is a “body OK” link (boolean).

Syntax

HTML is parsed according to WHATWG HTML (the living standard), which is also followed by all browsers.

Syntax tree

The syntax tree used is hast.

Types

This package is fully typed with TypeScript.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, hast-util-is-body-ok-link@^3, compatible with Node.js 16.

Security

As rehype works on HTML and improper use of HTML can open you up to a cross-site scripting (XSS) attack, use of rehype can also be unsafe. Use rehype-sanitize to make the tree safe.
