Use parameters

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

Parameter typeDescription
Strapi ContentSelect one or more entry from Strapi.

Strapi Content

This parameter type allows a Uniform user to select one or more Strapi entry.

Add parameter to component

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

  1. In Uniform, navigate to your component.

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

  3. The following values can be specified:

    NameDescription
    Allowed Content TypesSpecifies which content types will be available to select from when the parameter value is edited. You can select multiple content types in order to allow the user to select from a larger set of entries.
    Allow multiselectIndicates whether the user can select only one entry (the default), or more than one entry.
    Display field (optional)Each entry available to be selected when the parameter value is edited is displayed using the value of this field. If no value is specified, the field "title" is used.
    RequiredIndicates whether the value is required when the component is used.
    parameter-config
    Strapi Content parameter with a single content type selected.

Edit parameter value

When you use a component with a Strapi Content parameter, by default no entry will be selected. You are prompted to select an entry.

  1. Click Select.

    edit-value-default
  2. Click the document you want to select.

    edit-value-filters
    About this step

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

  3. Click Accept to save your selection.

    edit-value-selected
  4. You will see details about the document 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 entry in Strapi, click Edit.
    • If you want to unselect the entry, click Unlink.

Configure an enhancer

When an entry is selected, Uniform only stores the identifier for the entry. Your front-end application must retrieve the details for the entry. 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 Strapi.

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 entries.

{
"type": "strapi-content",
"value": {
"entries": [
{
"id": "######################",
}
],
}
}

Add the enhancer

Uniform provides an enhancer so you don't need to write the API calls to Strapi to retrieve data for documents.

tip

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

  1. In Strapi, get the following values:

    • Api token
    • Host
    About this step

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

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

    @uniformdev/canvas-strapi
  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,
    StrapiClient,
    STRAPI_PARAMETER_TYPES,
    } from '@uniformdev/canvas-strapi';
  5. Add the following code:

    const client = new StrapiClient({
    apiHost: '!!! YOUR STRAPI API HOST !!!',
    apiToken: '!!! YOUR STRAPI API TOKEN !!!',
    });
    About this step

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

  6. Add the following code:

    const strapiEnhancer = createEnhancer({ clients: client });
  7. Add the following code:

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

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

Next steps

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