This blog is pretty outdated and I've created an updated one here. Svelte ecosystem has matured a lot that, we really don't have to do a lot of complex configurations to get going, but its still not trivial. Again the content of this blog is outdated. Visit the updated one here.
First of all, here's the link to the Github repo, go ahead and start working on your project than fiddle with the configurations. Trust me that takes a hell lot of time.
Visit this website to see the outcome: Svelte + TailwindCSS + Storybook
// Quickstart
npx degit jerriclynsjohn/svelte-storybook-tailwind my-svelte-project
cd my-svelte-project
yarn
yarn dev
yarn stories
Svelte and TailwindCSS is an awesome combination for Frontend development, but sometimes the setup seems a bit non intuitive, especially when trying to try out this awesome combination. When integrating Storybook, which is another awesome tool for UI Component development and documentation, there is no obvious place to get how it's done. This repo was made to address just that!
You can easily start your project with this template, instead of wasting time figuring out configurations for each integration.
What do you get in this repo
- A fully functional Svelte + TailwindCSS integration with side-by-side implementation of independent Storybook
- Storybook with 5 essential Addons
- Storybook populated with basic examples of Svelte + TailwindCSS
Addons
- Accessibility Addon
- Accessibility Addon - Colorblindness Emulation
- Actions Addon
- Notes Addon
- Source Addon
- Viewport Addon
Svelte + TailwindCSS + Storybook
Storybook is an open source tool for developing JavaScript UI
components in isolation
Svelte is a component framework that allows you to write highly-efficient,
imperative code, that surgically updates the DOM to maintain performance.
TailwindCSS is a highly customizable, low-level CSS framework that gives
you all of the building blocks you need to build bespoke designs without any annoying opinionated
styles you have to fight to override.
Steps to build
- Clone this repo
git clone https://github.com/jerriclynsjohn/svelte-storybook-tailwind.git
- Go to the directory
cd svelte-storybook-tailwind
- Install dependencies
yarn
- To develop your Svelte App:
yarn dev
- To develop UI components independent of your app:
yarn stories
Documentations
- Svelte - API and Tutorial
- TailwindCSS - Docs and Tutorial
- Storybook - Docs and Tutorial (No Svelte Yet!)
Steps to build it all by yourself and some tips [Warning: It's lengthy]
Instantiate Svelte App
- Start the template file using
npx degit sveltejs/template svelte-storybook-tailwind
- Go to the directory
cd svelte-storybook-tailwind
- Install dependencies
yarn
- Try run the svelte app
yarn dev
Add Tailwind into the project
- Install dependencies:
yarn add -D tailwindcss @fullhuman/postcss-purgecss autoprefixer postcss postcss-import svelte-preprocess rollup-plugin-postcss
- Add
utils.css
insrc
and add this:
/* Import Tailwind as Global Utils */
@import 'tailwindcss/base';
@import 'tailwindcss/components';
@import 'tailwindcss/utilities';
Import this into the
main.js
import './utils.css'
Change the rollup config as shown:
import svelte from 'rollup-plugin-svelte';
import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import livereload from 'rollup-plugin-livereload';
import { terser } from 'rollup-plugin-terser';
import postcss from 'rollup-plugin-postcss';
import autoPreprocess from 'svelte-preprocess';
const production = !process.env.ROLLUP_WATCH;
export default {
input: 'src/main.js',
output: {
sourcemap: true,
format: 'iife',
name: 'app',
file: 'public/bundle.js',
},
plugins: [
svelte({
preprocess: autoPreprocess({
postcss: true,
}),
// enable run-time checks when not in production
dev: !production,
// we'll extract any component CSS out into
// a separate file — better for performance
css: css => {
css.write('public/bundle.css');
},
}),
postcss({
extract: 'public/utils.css',
}),
// If you have external dependencies installed from
// npm, you'll most likely need these plugins. In
// some cases you'll need additional configuration —
// consult the documentation for details:
// https://github.com/rollup/rollup-plugin-commonjs
resolve({
browser: true,
dedupe: importee => importee === 'svelte' || importee.startsWith('svelte/'),
}),
commonjs(),
// Watch the `public` directory and refresh the
// browser on changes when not in production
!production && livereload('public'),
// If we're building for production (npm run build
// instead of npm run dev), minify
production && terser(),
],
watch: {
clearScreen: false,
},
};
Add tailwind config using the command
npx tailwind init
Add PostCSS config
./postcss.config.js
as follows:
const production = !process.env.ROLLUP_WATCH;
const purgecss = require('@fullhuman/postcss-purgecss');
module.exports = {
plugins: [
require('postcss-import')(),
require('tailwindcss'),
require('autoprefixer'),
production &&
purgecss({
content: ['./**/*.html', './**/*.svelte'],
defaultExtractor: content => {
const regExp = new RegExp(/[A-Za-z0-9-_:/]+/g);
const matchedTokens = [];
let match = regExp.exec(content);
// To make sure that you do not lose any tailwind classes used in class directive.
// https://github.com/tailwindcss/discuss/issues/254#issuecomment-517918397
while (match) {
if (match[0].startsWith('class:')) {
matchedTokens.push(match[0].substring(6));
} else {
matchedTokens.push(match[0]);
}
match = regExp.exec(content);
}
return matchedTokens;
},
}),
],
};
Remove
global.css
frompublic
folder and then remove the reference fromindex.html
Build the project with some TailwindCSS utilities
yarn dev
Add Storybook into the Svelte Project
- Add Storybook dependencies
yarn add -D @storybook/svelte
-
Add 5 commonly used Storybook Addons:
-
Source:
yarn add -D @storybook/addon-storysource
-
Actions:
yarn add -D @storybook/addon-actions
-
Notes:
yarn add -D @storybook/addon-notes
-
Viewport:
yarn add -D @storybook/addon-viewport
-
Accessibility:
yarn add @storybook/addon-a11y --dev
-
Source:
Create an addon file at the root
.storybook/addons.js
with the following content and keep
adding additional addons in this file.
import '@storybook/addon-storysource/register';
import '@storybook/addon-actions/register';
import '@storybook/addon-notes/register';
import '@storybook/addon-viewport/register';
import '@storybook/addon-a11y/register';
- Create a config file at the root
.storybook/config.js
with the following content:
import { configure, addParameters, addDecorator } from '@storybook/svelte';
import { withA11y } from '@storybook/addon-a11y';
// automatically import all files ending in *.stories.js
const req = require.context('../storybook/stories', true, /\.stories\.js$/);
function loadStories() {
req.keys().forEach(filename => req(filename));
}
configure(loadStories, module);
addDecorator(withA11y);
addParameters({ viewport: { viewports: newViewports } });
- Add tailwind configs in the
webpack.config.js
under.storybook
and also accommodate for Source addon:
const path = require('path');
module.exports = ({ config, mode }) => {
config.module.rules.push(
{
test: /\.css$/,
loaders: [
{
loader: 'postcss-loader',
options: {
sourceMap: true,
config: {
path: './.storybook/',
},
},
},
],
include: path.resolve(__dirname, '../storybook/'),
},
//This is the new block for the addon
{
test: /\.stories\.js?$/,
loaders: [require.resolve('@storybook/addon-storysource/loader')],
include: [path.resolve(__dirname, '../storybook')],
enforce: 'pre',
},
);
return config;
};
- Create the
postcss.config.js
under.storybook
:
var tailwindcss = require('tailwindcss');
module.exports = {
plugins: [
require('postcss-import')(),
tailwindcss('./tailwind.config.js'),
require('autoprefixer'),
],
};
- Make sure you have babel and svelte-loader dependencies
yarn add -D babel-loader @babel/core svelte-loader
- Add npm script in your
package.json
{
"scripts": {
// Rest of the scripts
"stories": "start-storybook",
"build-stories": "build-storybook"
}
}
- Add a utils.css file under
storybook/css/
and make sure youimport 'utils.css'
in yourstories.js
files:
/* Import Tailwind as Global Utils */
@import 'tailwindcss/base';
@import 'tailwindcss/components';
@import 'tailwindcss/utilities';
- Write your Svelte component in
storybook\components
and yes you can use your regular.svelte
file. The only thing is that you cant use templates in a story yet, not supported, but yes you can compose other components together. For the starter pack lets just create a clickable button.
<script>
import { createEventDispatcher } from 'svelte';
export let text = '';
const dispatch = createEventDispatcher();
function onClick(event) {
dispatch('click', event);
}
</script>
<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded"
on:click={onClick}>
{text}
</button>
- Write your stories in
storybook/stories
and you can name any number of story file with<anything>.stories.js
, for the starter package we can create stories ofButton
with the readme notes at<anything>.stories.md
. Note: reference the css here to make sure that tailwind is called by postcss:
import '../../css/utils.css';
import { storiesOf } from '@storybook/svelte';
import ButtonSimple from '../../components/buttons/button-simple.svelte';
import markdownNotes from './buttons.stories.md';
storiesOf('Buttons | Buttons', module)
//Simple Button
.add(
'Simple',
() => ({
Component: ButtonSimple,
props: { text: 'Button' },
on: {
click: action('I am logging in the actions tab too'),
},
}),
{ notes: { markdown: markdownNotes } },
)
- Write your own Documentation for the Component which will
<anything>.stories.md
:
# Buttons
_Examples of building buttons with Tailwind CSS._
---
Tailwind doesn't include pre-designed button styles out of the box, but they're easy to build using
existing utilities.
Here are a few examples to help you get an idea of how to build components like this using Tailwind.
- Run your storyboard
yarn stories
and you'll see this:
You can add more addons and play around with them.
That's a wrap!

Anyone else getting "Uncaught SyntaxError: Unexpected token '<'" when trying to launch the Svelte app? I followed the instructions to a T and can see Storybook is working fine, but both the bundle.css and bundle.js are outputting the app's html.
Did you try running the code in the repo? Also can you share the error details?
Hi Jerric :) I decided to start over and the 2nd time round everything is working fine. Not sure where I went wrong before.
On an unrelated note, what would be the best way to add Sapper to the project? All the examples I've seen recommend starting with the Sapper template, but not anything about adding to existing templates.
TIA!
It can be done, but trust me going the template way is the best, you'll have to deal with both server side and client side dependencies. It's faster and straightforward with the template.
If you wanna add tailwind, just make sure you add the preprocess in both client and server side in the rollup config. To add story book it's the same process as mentioned in the blog here.
thanks, now i know to stay away from Svelte
I'm sure you'll be fine!!!
What's your problem with Svelte? Literally only one of the code blocks is svelte.. all the rest is the necessary config for storybook. If anything, you should be apprehensive of storybook.
Whats the best way to strip out the storybook stuff?
Wow, clone and installing gives

Thanks Volmancer! I ended up rebuilding the project from scratch and everything is working second time round. Gotta love dev!
That's wierd, I'll check it out myself on a fresh instance.
This works pretty much without doing this as well! Must be system specific.
