Patch Changes

• #​12252 cb9cd4e Thanks @​jerelmiller! - Changes the default behavior of the MaybeMasked type to preserve types unless otherwise specified. This change makes it easier to upgrade from older versions of the client where types could have unexpectedly changed in the application due to the default of trying to unwrap types into unmasked types. This change also fixes the compilation performance regression experienced when simply upgrading the client since types are now preserved by default.

  A new mode option has now been introduced to allow for the old behavior. See the next section on migrating if you wish to maintain the old default behavior after upgrading to this version.

Migrating from <= v3.12.4

If you've adopted data masking and have opted in to using masked types by setting the enabled property to true, you can remove this configuration entirely:

-declare module "@​apollo/client" {
-  interface DataMasking {
-    mode: "unmask"
-  }
-}

If you prefer to specify the behavior explicitly, change the property from enabled: true, to mode: "preserveTypes":

declare module "@​apollo/client" {
  interface DataMasking {
-    enabled: true
+    mode: "preserveTypes"
  }
}

If you rely on the default behavior in 3.12.4 or below and would like to continue to use unmasked types by default, set the mode to unmask:

declare module "@​apollo/client" {
  interface DataMasking {
    mode: "unmask";
  }
}
