What is Weaverse?

Weaverse is a visual page builder for Shopify Hydrogen. It lets merchants customize storefronts via a drag-and-drop Studio while developers build type-safe React components with schemas that define the editor UI.

2. Component Anatomy

Every Weaverse component has up to 3 exports from a single file (or directory):

// app/sections/my-section/index.tsx

// 1. Default export — React component
function MySection(props: MySectionProps) { ... }
export default MySection;

// 2. Schema export — editor configuration
export let schema = createSchema({ ... });

// 3. Loader export (optional) — server-side data fetching
export let loader = async (args: ComponentLoaderArgs<DataType>) => { ... };

Minimal Example

import { createSchema } from '@weaverse/hydrogen';
import type { HydrogenComponentProps } from '@weaverse/hydrogen';

interface BannerProps extends HydrogenComponentProps {
  heading: string;
  description: string;
}

function Banner({ heading, description, children, ...rest }: BannerProps) {
  return (
    <section {...rest} className="py-16 px-4 text-center">
      <h2 className="text-3xl font-bold">{heading}</h2>
      <p className="mt-4 text-lg text-gray-600">{description}</p>
      {children}
    </section>
  );
}

export default Banner;

export let schema = createSchema({
  type: 'banner',
  title: 'Banner',
  settings: [
    {
      group: 'Content',
      inputs: [
        { type: 'text', name: 'heading', label: 'Heading', defaultValue: 'Hello World' },
        { type: 'textarea', name: 'description', label: 'Description', defaultValue: 'Welcome to our store.' },
      ],
    },
  ],
  presets: {
    heading: 'Hello World',
    description: 'Welcome to our store.',
  },
});

Key Rules

• Spread {...rest} on the root element — required for Weaverse Studio interaction.
• Render {children} if the component accepts child components (childTypes).
• forwardRef is optional in React 19. If using React 18, wrap with forwardRef and attach ref to root element.
• type must be unique across all components, use kebab-case (e.g., hero-banner).

3. Component Registration

Components must be registered in app/weaverse/components.ts:

import type { HydrogenComponent } from '@weaverse/hydrogen';

// MUST use namespace imports (import * as X), NOT default imports
import * as HeroBanner from '~/sections/hero-banner';
import * as FeaturedCollection from '~/sections/featured-collection';
import * as ProductCard from '~/sections/product-card';

export let components: HydrogenComponent[] = [
  HeroBanner,
  FeaturedCollection,
  ProductCard,
];

Common mistake: Using import HeroBanner from ... — this won't work. Always import * as HeroBanner from ....

4. Schema with createSchema()

import { createSchema } from '@weaverse/hydrogen';

export let schema = createSchema({
  type: 'my-component',          // Unique kebab-case identifier
  title: 'My Component',         // Display name in Studio
  limit: 1,                      // Max instances per page (optional)
  enabled: ({ page, group }) =>  // Dynamic insertion availability (optional)
    ['PRODUCT', 'COLLECTION'].includes(page.type) && group === 'body',
  settings: [                    // Editor UI groups
    {
      group: 'Content',
      inputs: [
        { type: 'text', name: 'heading', label: 'Heading', defaultValue: 'Title' },
        { type: 'richtext', name: 'body', label: 'Body' },
        { type: 'image', name: 'image', label: 'Image' },
        {
          type: 'select', name: 'layout', label: 'Layout',
          configs: {
            options: [
              { value: 'grid', label: 'Grid' },
              { value: 'list', label: 'List' },
            ],
          },
          defaultValue: 'grid',
        },
      ],
    },
  ],
  childTypes: ['product-card', 'button'],  // Allowed child component types
  presets: {                     // Defaults when component is added to page
    heading: 'Title',
    layout: 'grid',
    children: [
      { type: 'product-card' },
      { type: 'product-card' },
    ],
  },
});

inspector is deprecated — always use settings.

enabledOn is deprecated — move page/group checks into enabled. The callback is synchronous, runs in the storefront preview, and receives { page: { id, type, handle, locale }, group }. Errors, Promises, and non-boolean results hide the component from new insertion without affecting existing instances. Studio currently evaluates the body group.

Page types for enabled: INDEX, PRODUCT, ALL_PRODUCTS, COLLECTION, COLLECTION_LIST, PAGE, BLOG, ARTICLE, CUSTOM

6. Data Fetching

import type { ComponentLoaderArgs, HydrogenComponentProps } from '@weaverse/hydrogen';

type MyData = { collectionHandle: string };

export let loader = async ({ weaverse, data }: ComponentLoaderArgs<MyData>) => {
  let { storefront } = weaverse;
  return await storefront.query(COLLECTION_QUERY, {
    variables: { handle: data.collectionHandle },
  });
};

// Derive props type from loader return
type Props = HydrogenComponentProps<Awaited<ReturnType<typeof loader>>> & MyData;

function MyComponent({ loaderData, ...rest }: Props) {
  let collection = loaderData?.collection;
  return <section {...rest}>{collection?.title}</section>;
}
export default MyComponent;

Key patterns:

• weaverse.storefront.query() — Shopify Storefront API
• weaverse.fetchWithCache(url, options) — External APIs with caching
• Promise.all([...]) — Parallel fetching
• shouldRevalidate: true on schema inputs that affect the loader

7. Styling & Theming

Tailwind CSS is the primary styling approach.

Global theme settings are defined in app/weaverse/schema.server.ts and applied via CSS variables:

// app/components/GlobalStyle.tsx
import { useThemeSettings } from '@weaverse/hydrogen';

export function GlobalStyle() {
  let settings = useThemeSettings();
  if (!settings) return null;
  return (
    <style dangerouslySetInnerHTML={{ __html: `
      :root {
        --color-primary: ${settings.colorPrimary};
        --body-base-size: ${settings.bodyBaseSize}px;
        --heading-base-size: ${settings.headingBaseSize}px;
      }
    `}} />
  );
}

CVA (Class Variance Authority) for component variants:

import { cva } from 'class-variance-authority';
let buttonVariants = cva('inline-flex items-center rounded font-medium', {
  variants: {
    variant: { primary: 'bg-blue-600 text-white', secondary: 'bg-gray-200' },
    size: { sm: 'h-8 px-3 text-sm', md: 'h-10 px-4', lg: 'h-12 px-6' },
  },
  defaultVariants: { variant: 'primary', size: 'md' },
});

8. Weaverse API (Key Hooks & Utilities)

→ Full details: references/10-weaverse-api.md

9. Server Setup (server.ts)

import { WeaverseClient } from '@weaverse/hydrogen';
import { components } from '~/weaverse/components';
import { themeSchema } from '~/weaverse/schema.server';

export async function createAppLoadContext(request, env, executionContext) {
  let hydrogenContext = createHydrogenContext({ env, request, cache, waitUntil, session, /* ... */ });
  return {
    ...hydrogenContext,
    weaverse: new WeaverseClient({
      ...hydrogenContext,
      request,
      cache,
      themeSchema,
      components,
    }),
  };
}

10. Route Integration

// app/routes/($locale)._index.tsx
import { WeaverseHydrogenRoot } from '@weaverse/hydrogen';

export async function loader({ context }: LoaderFunctionArgs) {
  let weaverseData = await context.weaverse.loadPage({ type: 'INDEX' });
  return { weaverseData };
}

export default function Homepage() {
  return <WeaverseHydrogenRoot />;
}

For product pages:

export async function loader({ context, params }: LoaderFunctionArgs) {
  let weaverseData = await context.weaverse.loadPage({
    type: 'PRODUCT',
    handle: params.productHandle,
  });
  return { weaverseData, /* other data */ };
}
