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 🙏

Storyblok RichText Resolver

Readme

🚀 Usage

If you are first-time user of the Storyblok, read the Getting Started guide to get a project ready in less than 5 minutes.

Installation

npm install @storyblok/richtext

or yarn:

yarn add @storyblok/richtext

or pnpm:

pnpm add @storyblok/richtext

Basic

import { richTextResolver } from '@storyblok/richtext';

const { render } = richTextResolver();

const html = render(doc);

document.querySelector<HTMLDivElement>('#app')!.innerHTML = `
  <div>
  ${html}
  </div>
`;

Overwrite resolvers

To overwrite an existing resolver, you can pass a property called resolvers available on the richTextResolver options.

import { MarkTypes, richTextResolver } from '@storyblok/richtext';

const html = richTextResolver({
  resolvers: {
    [MarkTypes.LINK]: (node) => {
      return `<button href="${node.attrs?.href}" target="${node.attrs?.target}">${node.children}</button>`;
    },
  },
}).render(doc);

Typing with Generics

It is possible to ensure correct typing support in a framework-agnostic way by using Typescript Generics

  • Vanilla string
  • Vue VNode
  • React React.ReactElement

This way the @storyblok/richtext is ignorant of framework specific types, avoiding having to import them and having vue react etc as dependencies.

// Vanilla
const options: StoryblokRichTextOptions<string> = {
  resolvers: {
    [MarkTypes.LINK]: (node: Node<string>) => {
      return `<button href="${node.attrs?.href}" target="${node.attrs?.target}">${node.children}</button>`;
    },
  },
};

const html = richTextResolver<string>(options).render(doc);
// Vue
const options: StoryblokRichTextOptions<VNode> = {
  renderFn: h,
  keyedResolvers: true,
};
const root = () => richTextResolver<VNode>(options).render(doc);
// React
const options: StoryblokRichTextOptions<React.ReactElement> = {
  renderFn: React.createElement,
  keyedResolvers: true,
};
const root = () => richTextResolver<React.ReactElement>(options).render(doc);

Optimize Images

To optimize images in the richtext, you can use the optimizeImages property on the richTextResolver options. For the full list of available options, check the Image Optimization documentation.

import { richTextResolver } from '@storyblok/richtext';

const html = richTextResolver({
  optimizeImages: {
    class: 'my-peformant-image',
    loading: 'lazy',
    width: 800,
    height: 600,
    srcset: [400, 800, 1200, 1600],
    sizes: ['(max-width: 400px) 100vw', '50vw'],
    filters: {
      format: 'webp',
      quality: 10,
      grayscale: true,
      blur: 10,
      brightness: 10,
    },
  },
}).render(doc);

Security: HTML Output Sanitization

[!WARNING] This package does not provide proper HTML sanitization by default

The @storyblok/richtext package primarly converts rich text content into HTML strings, which can then be rendered into the DOM of a web page. This means that any HTML output generated by the rich text resolver includes the raw content as it is defined in Storyblok, which may potentially include harmful or malicious scripts.

Why is Sanitization Important?

Injecting unsanitized HTML into your web application can expose it to cross-site scripting (XSS) attacks. XSS attacks can allow attackers to execute malicious scripts in the context of your website, potentially leading to data theft, session hijacking, and other security breaches.

Your Responsibility

As a developer using @storyblok/richtext, you are responsible for sanitizing the HTML output from the rich text resolver before injecting it into the DOM. This precaution helps prevent XSS attacks and ensures a safer web environment for your users.

Recommended Sanitization Libraries

To assist you in sanitizing HTML content, we recommend using the following library:

  • sanitize-html: A simple HTML sanitizer with a flexible API that can adjust to a wide range of applications.

    GitHub: sanitize-html

Example Usage

Here is an example of how you might sanitize HTML output using sanitize-html before rendering it to the DOM:

import sanitizeHtml from 'sanitize-html';
import { richTextResolver } from '@storyblok/richtext';

const html = richTextResolver().render(yourRichTextContent);
const sanitizedHTML = sanitizeHtml(html, {
  allowedTags: sanitizeHtml.defaults.allowedTags.concat(['img', 'figure', 'figcaption']),
  allowedAttributes: {
    ...sanitizeHtml.defaults.allowedAttributes,
    img: ['src', 'alt', 'title']
  }
});

document.getElementById('your-element-id').innerHTML = sanitizedHTML;
