20-20: Approved: Enhanced type safety withunknown.Changing the parameter type from
anytounknowninvalidateSerializablefunction enhances type safety by enforcing stricter type checks. This is a good practice in TypeScript to ensure that the function handles only explicitly defined types, which can help prevent runtime errors due to incorrect data types.packages/sdk/src/util/object.ts (2)
17-17: Approved: Import ofIndexabletype.The addition of the
Indexabletype import from@yorkie-js-sdk/src/document/documentenhances type specificity in thestringifyObjectValuesandparseObjectValuesfunctions. This change aligns with the PR's objective to improve type safety.
45-45: Approved: Enhanced type safety in utility functions.Modifying the type parameter from
<A extends object>to<A extends Indexable>in bothstringifyObjectValuesandparseObjectValuesfunctions improves type safety and ensures that these functions can handle objects that are specifically designed to be indexable. This adjustment reduces the risk of runtime errors associated with type mismatches and enhances the robustness of the code.Also applies to: 58-58

16-36: Approved: Enhanced type safety and flexibility inwithTwoClientsAndDocuments.The modification to include an additional generic type parameter
Pthat extendsIndexablein thewithTwoClientsAndDocumentsfunction enhances type safety and flexibility. This change allows the documents handled within the function to utilize a more specific type,Document<T, P>, ensuring that they can accommodate additional properties defined byP. This adjustment enhances the function's capability to work with a broader range of document types while maintaining type integrity.packages/sdk/src/devtools/types.ts (1)

89-92: Approved changes to handle attributes immutably.The introduction of
stringifiedAttributesin thebuildDescendantsfunction is a good practice. It enhances code clarity and robustness by ensuring that the original attributes object is not altered. This change helps prevent bugs and side effects associated with mutable data structures.
128-131: Approved consistent handling of attributes.The use of
stringifiedAttributesin thecreateCRDTTreeNodefunction mirrors the changes made inbuildDescendants. This consistency in handling attributes immutably across different functions is commendable and enhances maintainability.packages/sdk/src/client/client.ts (2)

Verified: The
broadcastmethod correctly handles theJsontype for thepayloadparameter.The method serializes the payload using
JSON.stringify, which is appropriate for JSON data. Integration tests confirm that the method behaves correctly with both serializable and unserializable payloads, ensuring robust handling of JSON serialization. No issues found with the implementation.Scripts executed

388-388: UpdatedBroadcastEventinterface to useJsontype for payload.The change from
anytoJsonfor thepayloadtype in theBroadcastEventinterface aligns with the PR's goal to ensure type safety by restricting types to JSON serializable values. This modification is crucial for preventing runtime errors due to type mismatches and ensures that the data structure is predictable and consistent across the system.
423-429: Definition ofJson,JsonScalar,JsonArray, andJsonObjecttypes.The introduction of these types is a significant enhancement in type safety for the SDK.
Jsonas a union ofJsonScalar,JsonArray, andJsonObjectprovides a clear and enforceable structure for JSON serializable data. This change supports the SDK's robustness by ensuring that only compatible data types are used throughout the system.
434-434: UpdatedIndexabletype to useJson.Changing the
Indexabletype fromRecord<string, any>toRecord<string, Json>is a critical update that aligns with the PR's objectives to enforce JSON serializability of the presence types. This change further tightens the type constraints and enhances the predictability and safety of the data handling within the SDK.
2068-2068: Updatedbroadcastmethod to acceptJsontype for payload.The update of the
broadcastmethod to accept apayloadof typeJsoninstead ofanyis a direct implementation of the PR's goal to enhance type safety. This change ensures that the method's payload is restricted to JSON serializable types, which is essential for consistent data serialization and transmission.

1-6: LGTM!The changes introduce a new type definition file for the
@tldraw/tldrawmodule. TheTDUserinterface is being extended to include theIndexabletype, which is imported from@yorkie-js-sdk/src/document/document. This change allows theTDUserinterface to have additional properties of typeJson, as defined by theIndexabletype.examples/vanilla-quill/src/type.ts (1)
10-10: Verify the impact of making theselectionproperty optional.The
selectionproperty in theYorkiePresencetype has been changed from a mandatory field to an optional field. This change allows instances ofYorkiePresenceto omit theselectionproperty entirely.Ensure that the code that interacts with
YorkiePresenceis updated to handle the case whereselectionis absent. Verify that this change does not introduce any unexpected behavior or break the functionality related to presence state management.examples/vanilla-quill/src/main.ts (1)
32-32: Verify the expected format of theembedvalue and its impact on the functionality.The
toDeltaOperationfunction has been modified to directly return theembedvalue without parsing it. This change suggests that theembedis now treated as a raw value rather than a JSON string.Ensure that the code that relies on the
embeddata is updated to handle the new format. Verify that this change does not introduce any unexpected behavior or break the functionality related to handling embedded data in the Quill editor.Consider adding documentation or comments to clarify the expected format of the
embedvalue and how it should be used.

Since the 1. react-tldraw In react-tldraw, we use export type YorkiePresenceType = {
tdUser: TDUser;
};However, 2. vanilla-quill Simillarly In vanilla-quil, the Presence type was previously defined as: export type YorkiePresence = {
// before
selection: TextPosStructRange | undefined;
// after
selection?: TextPosStructRange
};However, Additionally, I encountered a type issue in Here’s the updated Above changes are all included in the latest commit; please check if it okay :) |

Json Type to Restrict Presence Type to JSON Serializable Types
To prevent serialization issues, this commit narrows the type of the `presence` object `P`. Previously, `<P extends Indexable>` allowed any value type, including non-JSON serializable ones like byte arrays, Date, and Long. We now introduce a `Json` type, inspired by Liveblocks, to ensure only JSON serializable types are allowed in the presence object. This change affects functions like `broadcast`, ensuring safe serialization and addressing issues such as #884. The new `Json` type is defined as follows: ``` export type Json = JsonPrimitive | JsonArray | JsonObject; type JsonPrimitive = string | number | boolean | null; type JsonArray = Array<Json>; type JsonObject = { [key: string]: Json | undefined }; ``` This type restriction enhances type safety and prevents potential runtime errors during JSON serialization of presence data. --------- Co-authored-by: Youngteac Hong <susukang98@gmail.com>
What this PR does / why we need it?
This PR introduces a more restrictive type for the
presenceobjectP. Previously, the type<P extends Indexable>allowedanytype as a value, sinceIndexablewas defined asRecord<string, any>. This broad type allowed values that are not JSON serializable, such as byte arrays, Date, and Long, which could cause issues during serialization.To address this, we now restrict the type of
Pto only allow JSON serializable types. This ensures that the presence object contains values that can be safely serialized to JSON.Any background context you want to provide?
The
Jsontype introduced in this PR is based on a similar approach used by Liveblocks. Here’s the definition of theJsontype:With the introduction of the
Jsontype, we now enforce that only JSON serializable payloads can be broadcast, addressing issues like #884 . For instance, thebroadcastfunction has been updated as follows:What are the relevant tickets?
