A Shopify development toolkit.

This project is an active work in progress! The CLI is stable, but the theme itself is not.

Table of Contents

Quick Start

The easist way to get started with Slater is slater init. init outputs a default folder structure into the directory of your choice.

slater init <root>

Don't forget to install the dependencies.

npm install

You'll need to define one or more themes in the provided slater.config.js file to deploy to, similar to a standard Shopify config.yml file.

module.exports = {
  themes: {
    development: {
      id: '12345...',
      password: 'abcde...',
      store: '',
      ignore: [

Then, from the project root:

slater watch

And that's it! Slater will watch your local theme for changes and sync them to your remote site when they update 🎉.


Slater makes some assumptions out of the box, but it can be easily customized to fit most existing projects.


Slater projects require themes to be defined in the slater.config.js.

By default it looks for a theme called development:

module.exports = {
  themes: {
    development: { ... }

You can call it whatever you want though.

module.exports = {
  themes: {
    dev: { ... }

Just be sure to specify your theme name on the CLI:

slater build --theme dev

You can also define as many themes as you like. Use these for a production theme, staging, or whatever you like.

module.exports = {
  themes: {
    dev: { ... },
    test: { ... },
    live: { ... }

Directory Structure

All theme files should be located within a single source directory. By default, Slater looks for a /src directory in your project root.

To adjust this, specify an in prop on your config:

module.exports = {
  in: '/source'

Files within this directory will be built and copied to /build in your project root, and then synced to your remote theme.

To adjust your local build directory, specify an out prop on your config:

module.exports = {
  out: '/dist'


Slater uses Webpack internally to compile a single JavaScript entry point. By default, it looks for /src/scripts/index.js.

You can specify a different entry point using the assets object on your config:

module.exports = {
  assets: {
    in: '/source/scripts/index.js'

Slater uses PostCSS by default. It's configured to allow SASS-like nesting, in addition to all modern CSS goodies.

To compile your styles, simply import your root stylesheet into your JavaScript entrypoint:

import '../styles.css'
// rest of your project scripts

You can also use SASS. Simple specify the sass preset in your assets config:

module.exports = {
  assets: {
    presets: [

Alias & Env

To make your JavaScript a little easier to work with, Slater supports alias definitions and environment variables.

module.exports = {
  alias: {
    components: './src/scripts/components'
  env: {
    API_KEY: 'abcde...'

Which you can then use in your JavaScript like this:

import api from 'components/api.js'
const fetcher = api({
  key: API_KEY

For convenience, there's also a built-in alias @ that points to the directory containing your JavaScript entry point.

Keep in mind, these environment variables are public, so don't use them for any secret keys, passwords, or any value that you need to keep private!

Command Line


Watches for file changes and syncs updates to your specified theme.

slater watch


Compiles assets and copies all files from the directory to the config.out directory.

slater build


Sync local files or directories to your remote theme. A direct interface to [@slater/sync], which @slater/cli uses internally.

slater sync build/snippets/hero.liquid # file 
slater sync build/snippets # directory 
slater sync # defaults to config.out 


Any of the core commands can be combined with the following options:

  • --config <path> - specify the path to your config file
  • --theme <name> - specify a named theme from your config file


To deploy a theme, combine the above commands as needed:

slater build && slater sync --theme production

Live-reloading & HTTPS

slater uses an local SSL certification to correspond with Shopify's HTTPS hosted themes. To take advantage of live-reloading, you need to create a security exception for the slater cert (this is safe). To do this, load https://localhost:3000 in your browser, and follow the instructions for adding an exception. If it works, you should see this in your browser window:

slater running
