Svelte Tailwind2 Starter

Svelte + TailwindCSS 2.0 starter template

Svelte + TailwindCSS 2.0 + RollupJS starter

Starter template for Svelte + TailwindCSS apps.

It has built-in support for TailwindCSS 2.0, while the bundling is handled by Rollup.

There's also a simple dark/light mode switch, and a surprise button 👇

🚨 Limitations

In development mode (running npm run dev / yarn dev), the CSS bundle includes all of TailwindCSS and weighs in at ~6.8MB. You don't want to deploy this to production.

In production mode (running npm run build / yarn build), all the unused CSS styles are purged, dropping the bundle to a much more manageable size (~7KB in this case). However, I haven't yet found a way to stop Tailwind from purging dynamic Svelte classes (such as class:dark or class:from-blue-700={$dark}).

As a result, the production bundle won't contain such dynamic classes. To get around this, in tailwind.config.js, under purge, add an options object with a safelist array containing all the classes you wish to protect from purging:

purge: {
    enabled: production,
    content: [
    options: {
        safelist: [

Get started

Install the dependencies...

cd svelte-app
npm install

...then start Rollup:

npm run dev

Navigate to localhost:5000. You should see your app running. Edit a component file in src, save it, and reload the page to see your changes.

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host

Building and running in production mode

To create an optimised (production) version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Single-page app mode

By default, sirv will only respond to requests that match files in public. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.

If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for any path. You can make it so by editing the "start" command in package.json:

"start": "sirv public --single"

Deploying to the web

With now

Install now if you haven't already:

npm install -g now

Then, from within your project folder:

cd public
now deploy --name my-project

As an alternative, use the Now desktop client and simply drag the unzipped project folder to the taskbar icon.

With surge

Install surge if you haven't already:

npm install -g surge

Then, from within your project folder:

npm run build
surge public
