Function isEntryReplacementComponent

Parameters

• component:
      | {
          baseline: { hidden?: boolean; id: string };
          type?: "EntryReplacement";
          variants: { hidden?: boolean; id: string }[];
      }
      | {
          baseline: {
              value: string
              | number
              | boolean
              | Record<string, JSONType>
              | null;
          };
          key: string;
          type: "InlineVariable";
          valueType: "Boolean"
          | "Number"
          | "Object"
          | "String";
          variants: {
              value: string | number | boolean | Record<string, JSONType> | null;
          }[];
      }

  Personalization component to test.

  • {
        baseline: { hidden?: boolean; id: string };
        type?: "EntryReplacement";
        variants: { hidden?: boolean; id: string }[];
    }

    • baseline: { hidden?: boolean; id: string }

      Baseline variant used when no targeting or allocation selects another variant.

      • Optionalhidden?: boolean

        On a baseline: true excludes the whole component from allocation.

        On a variant: can be true (author chose "Use empty variant") or false (unfilled placeholder). Both states share id: "". Do not use this field to detect an empty variant — use id === "" instead. The Experience API strips this field before runtime; it is only present in Contentful CDA nt_config.

      • id: string

        Unique identifier for the variant. Empty string ("") for an empty variant — both the deliberate "Use empty variant" choice and an unfilled placeholder slot.

    • Optionaltype?: "EntryReplacement"

      Discriminator for the component type.

      Remarks

      Can be omitted, in which case the component is treated as an EntryReplacement.

    • variants: { hidden?: boolean; id: string }[]

      Additional variants that can be served.

  • {
        baseline: {
            value: string | number | boolean | Record<string, JSONType> | null;
        };
        key: string;
        type: "InlineVariable";
        valueType: "Boolean"
        | "Number"
        | "Object"
        | "String";
        variants: {
            value: string | number | boolean | Record<string, JSONType> | null;
        }[];
    }

    • baseline: { value: string | number | boolean | Record<string, JSONType> | null }

      Baseline value used when no targeting or allocation selects another variant.

      • value: string | number | boolean | Record<string, JSONType> | null

        Variant value for the inline variable.

    • key: string

      Key under which this variable is exposed to the template.

    • type: "InlineVariable"

      Discriminator for the inline variable component.

    • valueType: "Boolean" | "Number" | "Object" | "String"

      Describes the runtime type of the values for this variable.

    • variants: { value: string | number | boolean | Record<string, JSONType> | null }[]

      Additional variable variants for experimentation or personalization.
