Examples
Section titled ExamplesLink previews automatically appear when you pasting a link into a post, providing a glimpse of what’s been linked to. This approach has been popularized by Slack, Twitter, Facebook, etc. Link previews should be tailored to fit the content received from each third party. It might be appropriate to use atomic utility classes for further customization, but Stacks provides a few reusable patterns:
Base style
Section titled Base styleUse for links whose expected body is rich text or markdown like Jira issues or Slack messages. Wherever possible, it’s best practice to support basic markdown formatting (bold, italics, line breaks, lists, etc.)

I'm trying to create a simple fetch with hooks from an AWS database. At the moment it errors out and the only reason I can see is because it breaks the rules of hooks but I'm not sure how. It's at the top level of this functional component and it's not called inside an event handler.
The result of this call (an array of user data), needs to be exported as a function and called in another file.
If anyone can spot something I have missed and can highlighted how I'm breaking the rules of hooks I'd be grateful!
Thanks!
Code blocks
Section titled Code blocksUse for links whose expected body is code like code files or GitHub Gists. In these scenarios, replace s-link-preview--body
class with s-link-preview--code
.
Add a s-code-block
class to the <pre>
tag if you’d like to apply highlight.js’s syntax highlighting on Stack Exchange sites with this option enabled.
<div class="s-link-preview">
<div class="s-link-preview--header">
<div class="s-link-preview--icon">@Svg.Icon</div>
<div>
<a href="#" class="s-link-preview--title">…</a>
<div class="s-link-preview--details">…</div>
</div>
</div>
<div class="s-link-preview--code">
<pre class="s-code-block">
<code>…</code>
</pre>
</div>
<div class="s-link-preview--footer">
<a href="#" class="s-link-preview--url">…</a>
<div class="s-link-preview--misc">(truncated)</div>
</div>
</div>
'use strict';
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
version: '<%= pkg.version %>',
// Shell commands for use in Grunt tasks
shell: {
eleventyBuild: {
command: 'npx @11ty/eleventy',
options: {
stderr: false,
execOptions: {
cwd: 'docs'
}
}
Code blocks with line numbers
Section titled Code blocks with line numbersYou can further configure highlight.js’s syntax highlighting to include line numbers by adding the class linenums
to the prettified <pre>
tag containing the code. See also Code blocks.
Class | Description |
---|---|
linenums |
Count starts at line 1 |
linenums:<n> |
Count starts at line <n> |
