Use parameters

After you install the Squidex integration, the following parameter types are available. You can use these to incorporate content from Squidex into your components and compositions.

Parameter typeDescription
Squidex ContentSelect one or more content item from Squidex.

Squidex Content​

This parameter type allows a Uniform user to select one or more Squidex content item.

Add parameter to component​

In order to allow a user to select a content item from Squidex, you must add a parameter to a component. The parameter is used to store the identifier to the selected content item when the user selects it.

  1. In Uniform, navigate to your component.

  2. Add a new parameter using the parameter type Squidex Content.

  3. The following values can be specified:

    NameDescription
    Allowed Content SchemasSpecifies which content schema will be available to select from when the parameter value is edited. You can select multiple content schema in order to allow the user to select from a larger set of content items.
    Allow multiselectIndicates whether the user can select only one content item (the default), or more than one content item.
    RequiredIndicates whether the value is required when the component is used.
    parameter-config
    Squidex Content parameter with one content schema selected.

Edit parameter value​

When you use a component with a Squidex Content parameter, by default no content item will be selected. You are prompted to select content item.

  1. Click Select.

  2. Click the content item you want to select.

    About this step

    A couple of filters are available. The dropdown allows you to filter by content schema. The text box allows you to filter by item content.

  3. Click Accept to save your selection.

  4. You will see details about the content item you selected, including the title and some metadata.

    edit-value-saved
    About this step

    After your selected is saved, you are presented with the following options:

    • If you want to edit the selected content item in Squidex, click Edit.
    • If you want to unselect the entry, click Unlink.

Configure an enhancer​

When a content item is selected, Uniform only stores the identifier for the content item. Your front-end application must retrieve the details for the content item. Uniform provides an enhancer to simplify this process.

tip

Using the enhancer provided by Uniform saves you from having to write logic to interact directly with Squidex.

How Uniform stores the selected document​

The following is an example of what Uniform stores for the parameter. It stores the identifiers for the selected content items.

{
  "type": "squidex-content",
  "value": {
    "entries": [
      {
        "id": "########-####-####-####-############",
        "contentSchema": "posts"
      }
    ]
  }
}

Add the enhancer​

Uniform provides an enhancer so you don't need to write the API calls to Squidex to retrieve data for content items.

tip

For more information about the enhancer, see the package documentation.

  1. In Squidex, get the following values:

    • App name
    • Client ID
    • Client secret
    About this step

    These are the same values used to configure the Squidex integration in Canvas.

  2. Add the following npm packages to your front-end application:

    @uniformdev/canvas-squidex

  3. In a text editor, open the file where you retrieve the composition definition from Uniform.

    About this step

    You are looking for the code calls the async function getComposition. The code below assumes the object returned is set in a variable composition.

  4. Add the following import statements:

    import { EnhancerBuilder, enhance } from '@uniformdev/canvas';
    import {
      createEnhancer,
      SquidexClient,
      SQUIDEX_PARAMETER_TYPES,
    } from '@uniformdev/canvas-squidex';

  5. Add the following code:

    const squidexClient = new SquidexClient({
      appName: '!!! YOUR SQUIDEX APP NAME !!!',
      clientId: '!!! YOUR SQUIDEX CLIENT ID !!!',
      clientSecret: '!!! YOUR SQUIDEX CLIENT SECRET !!!',
    });
    About this step

    We recommend you moving the Squidex credentials to environment variables rather than hard-coding them in the front-end app.

  6. Add the following code:

    const enhancer = createEnhancer({
      clients: squidexClient,
    });

  7. Add the following code:

    await enhance({
      composition,
      enhancers: new EnhancerBuilder().parameterType(
        SQUIDEX_PARAMETER_TYPES,
        enhancer,
      ),
      context: {},
    });
    About this step

    This registers the enhancer to be used for any occurrence of the Squidex Content parameter.

Next steps

Now, the parameter value in the composition is mutated to include the field values for the selected Squidex content items (instead of just being identifiers).
