@apollo/client

Minor Changes

Data masking

• Introduces data masking in Apollo Client.

  Data masking enforces that only the fields requested by the query or fragment is available to that component. Data masking is best paired with colocated fragments.

  To enable data masking in Apollo Client, set the dataMasking option to true.

  new ApolloClient({
    dataMasking: true,
    // ... other options
  });

  For detailed information on data masking, including how to incrementally adopt it in an existing applications, see the data masking documentation.

• Allow null as a valid from value in useFragment.

More Patch Changes

• Maintain the existing document if its unchanged by the codemod and move to more naive whitespace formatting

• Fix issue when using Unmasked with older versions of TypeScript when used with array fields.

• Prevent field accessor warnings when using @unmask(mode: "migrate") on objects that are passed into cache.identify.

• Provide a codemod that applies @unmask to all named fragments for all operations and fragments.

  Learn how to use the codemod in the incremental adoption documentation.

• Fix issue where data went missing when an unmasked fragment in migrate mode selected fields that the parent did not.

• Data masking types: handle overlapping nested array types and fragments on interface types.

• Fix issue where masked data would sometimes get returned when the field was part of a child fragment from a fragment unmasked by the parent query.

• Warn when using data masking with "no-cache" operations.

• Fix issue where the warning emitted by @unmask(mode: "migrate") would trigger unnecessarily when the fragment was used alongside a masked fragment inside an inline fragment.

• Fix error when combining @unmask and @defer directives on a fragment spread when data masking is enabled.

• Fix error thrown when applying unmask migrate mode warnings on interface types with selection sets that contain inline fragment conditions.

• Add a helper that will skip the TS unmasking alorithm when no fragments are present on type level

• Ensure documents unchanged by the codemod are left untouched.

• Ensure null is retained in nullable types when unmasking a type with the Unmasked helper type.

• Fix issue that threw errors when masking partial data with @unmask(mode: "migrate").
