### Define Spacing Tokens in Easyblocks

Source: https://docs.easyblocks.io/essentials/configuration

This example demonstrates defining spacing tokens in Easyblocks. It includes standard pixel values and responsive values using viewport width units (`vw`). The `id`, `label`, and `value` structure is used, with `value` supporting responsive objects.

```typescript
export const config: Config = {
  // ...,
  tokens: {
    // ...,
    space: [
      {
        id: "0",
        label: "0",
        value: "0px",
      },
      {
        id: "1",
        label: "1",
        value: "1px",
      },
      {
        id: "2",
        label: "2",
        value: "2px",
      },
      {
        id: "4",
        label: "4",
        value: "4px",
      },
      {
        id: "6",
        label: "6",
        value: "6px",
      },
      {
        id: "8",
        label: "8",
        value: "8px",
      },
      {
        id: "12",
        label: "12",
        value: "12px",
      },
      {
        id: "16",
        label: "16",
        value: "16px",
      },
      {
        id: "24",
        label: "24",
        value: "24px",
      },
      {
        id: "32",
        label: "32",
        value: "32px",
      },
      {
        id: "48",
        label: "48",
        value: "48px",
      },
      {
        id: "64",
        label: "64",
        value: "64px",
      },
      {
        id: "96",
        label: "96",
        value: "96px",
      },
      {
        id: "128",
        label: "128",
        value: "128px",
      },
      {
        id: "160",
        label: "160",
        value: "160px",
      },
      {
        id: "containerMargin.standard",
        label: "Standard",
        value: {
          // responsive value
          $res: true,
          md: "5vw", // vw units are allowed for "space" type
          lg: "8vw",
        },
      },
      {
        id: "containerMargin.large",
        label: "Large",
        value: {
          // repsonsive value
          $res: true,
          xs: "5vw",
          md: "8vw",
          lg: "12vw",
        },
      },
    ],
    // ...
  },
};
```

### Custom Backend Interface Definition

Source: https://docs.easyblocks.io/essentials/backend

This TypeScript interface defines the contract for a custom Easyblocks backend. It specifies the methods required for managing documents (get, create, update) and templates (get, getAll, create, update, delete).

```typescript
export type Backend = {
  documents: {
    get: (payload: { id: string; locale?: string }) => Promise<Document>;
    create: (payload: Omit<Document, "id" | "version">) => Promise<Document>;
    update: (payload: Omit<Document, "type">) => Promise<Document>;
  };
  templates: {
    get(payload: { id: string }): Promise<UserDefinedTemplate>;
    getAll: () => Promise<UserDefinedTemplate[]>;
    create: (payload: {
      label: string;
      entry: NoCodeComponentEntry;
      width?: number;
      widthAuto?: boolean;
    }) => Promise<UserDefinedTemplate>;
    update: (payload: {
      id: string;
      label: string;
    }) => Promise<Omit<UserDefinedTemplate, "entry">>;
    delete: (payload: { id: string }) => Promise<void>;
  };
};

export type Document = {
  id: string;
  version: number;
  entry: NoCodeComponentEntry;
};

export type UserDefinedTemplate = {
  id: string;
  label: string;
  thumbnail?: string;
  thumbnailLabel?: string;
  entry: NoCodeComponentEntry;
  isUserDefined: true;
  width?: number;
  widthAuto?: boolean;
};
```

--------------------------------

### Defining No-Code Components in Easyblocks

Source: https://docs.easyblocks.io/essentials/configuration

Specifies the No-Code Component Definitions available in the Easyblocks setup. Each component has an ID and a schema defining its properties.

```typescript
importtype { Config } from'@easyblocks/core';
constconfig:Config= {
  ...,
  components: [
    {
      id:'MyNoCodeComponent',
      schema: [
        {
          prop:'title',
          type:'string',
          label:'Title'
        }
      ]
    }
  ]
};
```

--------------------------------

### Resolve Product References in Fetcher

Source: https://docs.easyblocks.io/essentials/external-data

This example demonstrates a complete fetcher implementation within the `onExternalDataChange` callback. It filters external references for the 'product' widget, finds matching products from a local array, and returns the resolved data or an error if a product is not found.

```javascript
const products = [
  {
    id: "1",
    title: "Product 1",
    price: 25.0,
  },
  {
    id: "2",
    title: "Product 2",
    price: 10.0,
  },
  {
    id: "3",
    title: "Product 3",
    price: 50.0,
  },
  {
    id: "4",
    title: "Product 4",
    price: 150.0,
  },
];
const [externalDataValues, setExternalDataValues] = useState<ExternalData>(
  {}
);
<EasyblocksEditor
  ...
  onExternalDataChange={async externals => {
    // (1)
    const productReferences = Object.entries(externals)
      .filter(([, reference]) => {
        // Why do we check `widgetId` instead of `type`?
        // We could rely on `type` field, but we could have multiple widgets for
        // the same type and they could be resolved differently.
        // Why do we check for empty `id`? 
        // Changing from non empty value to empty is also a change
        return reference.widgetId === 'product' && reference.id !== null;
      });
    const resolvedProducts = Object.fromEntries(
      productReferences.map(([id, reference]) => {
        // (2)
        const product = products.find(p => p.id === reference.id);
        // (3)
        if (!product) {
          // If product wasn't resolved/found, we report an error
          return [id, { error: new Error(
            `Product with id ${reference.id} was not found`
          )}]
        }
        // (3) If found, return it as resolved external data
        return [id, { type: 'product', value: product }];
    }));
    // We inform editor about change by updating `externalDataValues` state variable
    // with new data
    setExternalDataValues({
      ...externalDataValues,
      ...resolvedProducts
    });
  }}
/>
```

### No-Code Entry with Selected Product ID

Source: https://docs.easyblocks.io/essentials/external-data

This JSON snippet shows an example of a No-Code Entry storing the 'id' and 'widgetId' of a selected product, demonstrating that only the identifier is stored, not the full data.

```json
{
  "product": {
    "id": "3",
    "widgetId": "product"
  }
}
```

--------------------------------

### Define Compound Type for Product Data

Source: https://docs.easyblocks.io/essentials/external-data

Illustrates how to structure compound data in Easyblocks, returning multiple basic data types within a single object. This example shows returning a product's title, primary image, and the full product object.

```javascript
{
  type: "object",
  value: {
    productTitle: {
      type: "text",
      value: product.title
    },
    productPrimaryImage: {
      type: "image",
      value: product.images[0]
    },
    self: {
      type: "product",
      value: product
    }
  ]
}
```

### Handle Easyblocks Editor Events

Source: https://docs.easyblocks.io/essentials/editor-page

This example shows how to listen for postMessage events sent from the Easyblocks editor within an iframe. It uses a `useEffect` hook to add and remove an event listener to the iframe's content window, allowing you to handle events like `@easyblocks/closed` and `@easyblocks/content-saved`.

```JavaScript
// We use state instead of ref on purpose to exactly know when the node is attached
// so we could react to it.
const [iframeNode, setIframeNode] = useState<HTMLIFrameElement | null>(null);
useEffect(() => {
  function handleMessage(event: MessageEvent) {
    if (event.data.type === "@easyblocks/closed") {
      // handle closed event
    }
    if (event.data.type === "@easyblocks/content-saved") {
      // handle content saved event
    }
  }
  iframeNode?.contentWindow?.addEventListener("message", handleMessage);
  return () => {
    iframeNode?.contentWindow?.removeEventListener("message", handleMessage);
  };
}, [iframeNode]);
return (
  <iframe
    src={`/your-editor-page?rootContainer=myContainer&mode=app`}
    ref={setIframeNode}
  ></iframe>
);
```

### Build Easyblocks Document

Source: https://docs.easyblocks.io/essentials/rendering-content

Prepares an Easyblocks document for rendering by processing it through a build phase. Requires document ID, configuration, and locale.

```javascript
import { buildDocument } from"@easyblocks/core";
const { renderableDocument } =await buildDocument({
  documentId:"<your_document_id>",
  config: easyblockConfig,
  locale:"<your_desired_locale>",
});
```

### Implement Product Picker Widget with SimplePicker

Source: https://docs.easyblocks.io/essentials/external-data

Demonstrates how to use the SimplePicker component from '@easyblocks/design-system' to create a product selection widget. It shows how to implement `getItems` for searching and `getItemById` for fetching item details.

```typescript
import { WidgetComponentProps } from "@easyblocks/core";
import { SimplePicker } from "@easyblocks/design-system";

const products = [
  {
    id: "1",
    title: "Product 1",
    price: 25.0,
  },
  {
    id: "2",
    title: "Product 2",
    price: 10.0,
  },
  {
    id: "3",
    title: "Product 3",
    price: 50.0,
  },
  {
    id: "4",
    title: "Product 4",
    price: 150.0,
  },
];

function ProductPickerWidget(props: WidgetComponentProps) {
  return (
    <SimplePicker
      value={props.id}
      onChange={props.onChange}
      getItems={async (query) => {
        const filteredItems = products.filter((p) => p.title.includes(query));
        return filteredItems.map((i) => {
          return {
            id: i.id,
            name: i.title,
          };
        });
      }}
      getItemById={async (id) => {
        const item = products.find((p) => p.id === id);
        return {
          id: item.id,
          name: item.title,
        };
      }}
    />
  );
}
```

### Create Easyblocks Editor Page

Source: https://docs.easyblocks.io/essentials/editor-page

This snippet demonstrates how to create a dedicated editor page for Easyblocks. It imports the EasyblocksEditor component and the project's configuration, then renders the editor with the provided configuration and no-code component instances.

### Text Type Configuration (Localizable String)

Source: https://docs.easyblocks.io/essentials/no-code-components/schema

Configures a localizable text property for a component, allowing different values for different locales, such as titles or descriptions. The UI provides a text input that handles localization. Values are stored in a locale-specific object.

```json
{
  "prop": "title",
  "type": "text",
  "label": "Title"
}
```

```json
{
  "title": {
    "en-US": "Hello world"
  }
}
```
