A blank theme to get you started with Shopify theme dev, featuring TailwindCSS. Built ontop of Theme Lab.

• With the release of Online Store 2.0 and the new starter theme, Dawn, Shopify have really leaned into the idea of using theme sections as individual components.
• Each section file in Dawn imports its own JS and CSS files. This means that the browser is only rendering the styles and scripts necessary for this section, improving not just site performance but also the customizer experience for merchants.
• The concept for this starter was to enable a similar "section first" approach to theme development. Each section has a corresponding JS and CSS file, which get compiled to the /assets directory. The minifyed assets are then imported into the section using the asset_url filter.

1. Ensure you have the following prerequisites installed:
   • Ruby v2.7+
   • Shopify CLI v2+
   • Node.js v14+
2. Run shopify login --store <your-store.myshopify.com>
3. Clone this repo or enter the following command: shopify theme init -u https://github.com/lilyfielding/shopify-cli-starter.git
4. Run npm install
5. Run npm run start

• The starter is using the Liquid Schema Plugin. This allows us to write the schema for each section in JS, so we can do things like repeat certain customizer fields across multiple sections without having to write the same code every time.
  • Please refer to this blog post for more use-cases and capabilities.
• The plugin will look for section files in the ./src/sections/liquid directory, and output these to ./shopify/sections.
• The schema for each section is written in its own JS file in ./src/sections/schema like so:

  // ./src/sections/schema/hero.js
  
  module.exports = {
    name: 'Hero Banner',
    settings: [
      {
        label: 'Title',
        id: 'title',
        type: 'text'
      }
    ]
  }
  

• We then import the schema into the section's liquid file like so:

  // ./src/sections/liquid/hero.liquid
    
  <div class="hero"></div>
    
  {% schema 'hero' %}
  

• The outputted section file will look like the following:

  // ./shopify/sections/hero.liquid
    
  <div class="hero"></div>
    
  {% schema %}
    {
      "name: "Hero Banner",
      "settings": [
        {
          "label": "Title",
          "id": "title",
          "type": "text"
        }
      ]
    }
  {% endschema %)
  

• Each of the JS files in ./src/sections/scripts will be minified by webpack and outputted to the ./shopify/assets folder like so: [file_name].section.js
  • Please Note: The development server will need to be restarted every time you add a new script.
• Any CSS files included in the javascript will also be outputted to ./shopify/assets like so: [file_name].section.js
  • Since Webpack is JS focussed, each CSS file will need to be imported into a JS file for this to work, even if there is no javascript associated with the section.
• The minified assets should then be included in each section like so:

  // ./src/sections/liquid/hero.liquid
  
  <div class="hero"></div>
  
  {% schema 'hero' %}
  {{ 'hero.section.css' | asset_url | stylesheet_tag }}
  {{ 'hero.section.js' | asset_url | script_tag }}
  

• Currently the starter is still kind of a WIP, and while I do want to pursue a dev strategy that's as close as possible to what Shopify expects, I haven't had chance to test this on a real project yet – so I can't yet vouch for how performant this idea will be.
• If you give this a go but find this section-first approach isn't working out, you can disable the above by deleting the following from ./.config/webpack/webpack.common.js:

  const path = require("path");
  const { CleanWebpackPlugin } = require("clean-webpack-plugin");
  const MiniCssExtractPlugin = require("mini-css-extract-plugin");
  const LiquidSchemaPlugin = require("liquid-schema-plugin");
  
  <!--   Delete this line     -->
  const sectionEntries = require("./utils/getSections");
  
  module.exports = {
    stats: "minimal",
    entry: {
      global: path.resolve(__dirname, "../../src/global.js"),
      <!--      And this line      -->
      ...sectionEntries(),
    },
  

• You can then simply import all of your stylesheets into global.css rather than splitting them out by section.
