Storybook Addon HTML Adjustments
This fork is adjusted version of https://github.com/whitespace-se/storybook-addon-html
If you are not sure which version you should use, always use the original one.
The reason for this fork was ability to dispatch message html-plugin-code-received to story's iframe, after rendered HTML code is updated.
...
useEffect(() => {
setCode(prettierFormat(html, prettierConfig));
const event = new Event('html-plugin-code-received');
document.dispatchEvent(event);
}, [html]);
...Storybook Addon HTML
This addon for Storybook adds a tab that displays the compiled HTML for each story. It uses highlight.js for syntax highlighting.

Getting Started
With NPM:
npm i --save-dev @whitespace/storybook-addon-htmlWith Yarn:
yarn add -D @whitespace/storybook-addon-htmlRegister addon
// .storybook/main.js
module.exports = {
// ...
addons: [
'@whitespace/storybook-addon-html',
// ...
],
};Usage
The HTML is formatted with Prettier. You can override the Prettier config
(except parser and plugins) by providing an object following the
Prettier API override format in the
html parameter:
// .storybook/preview.js
export const parameters = {
// ...
html: {
prettier: {
tabWidth: 4,
useTabs: false,
htmlWhitespaceSensitivity: 'strict',
},
},
};You can override the wrapper element selector used to grab the component HTML.
export const parameters = {
html: {
root: '#my-custom-wrapper', // default: #root
},
};When using Web Components, the HTML will contain empty comments, i.e. <!---->.
If you want to remove these, use the removeEmptyComments parameter:
export const parameters = {
html: {
removeEmptyComments: true, // default: false
},
};You can override the showLineNumbers and wrapLines settings for the syntax
highlighter by using the highlighter parameter:
export const parameters = {
html: {
highlighter: {
showLineNumbers: true, // default: false
wrapLines: false, // default: true
},
},
};Supported frameworks
As of version 4.0.0 all frameworks are supported per default 🎉
