Sanity parameters

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

Sanity Entry Selector#

This parameter type allows a Uniform user to select a single Sanity entry.

Add parameter to component#

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

1. In Uniform, navigate to your component.

2. Add a new parameter using the parameter type Sanity Entry Selector.

3. The following values can be specified:

   Name	Description
   Allowed Content Types	Specifies 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.
   Searchable Fields	Specifies which fields are searched when the keyword filter is used.
   Required	Indicates whether the value is required when the component is used.

   

   Sanity Entry Selector parameter with a multiple content types and one searchable field set.

Edit parameter value#

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

1. Click Select.

   

2. Click the entry you want to select.

   About this step

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

   • 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.

How Uniform stores the selected item#

The following is an example of what Uniform stores for the parameter.

There is one identifier in this value:

1. The entry that was selected.

Add the enhancer#

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

1. In Sanity, get the following values:

   • Project ID
   • Delivery API key (optional)

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

   CopyCopied!Wrap

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