1523-1527: Handle Possible Undefined Value from 'toVersionVector'In the function
versionVectorToHex, there's an assumption thattoVersionVector(vector)will not returnundefineddue to the non-null assertion operator!:const pbVersionVector = toVersionVector(vector)!;If
vectorcan beundefined, this could lead to a runtime error.Ensure that

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 <[email protected]>
Implement a new BroadcastOptions interface to allow for automatic retries on network failures during broadcasts. This enhancement improves resilience against temporary network issues, ensuring more reliable message delivery. The maxRetries option allows users to control retry behavior, with a default of 0 (no retries). Only network errors trigger retries; other errors, such as unserializable payloads, will not initiate retry attempts.
Enhance splay tree efficiency by incorporating splay operations after node location in Find and IndexOf functions. This change maintains the tree's self-balancing property and ensures amortized O(log n) time complexity for future operations. Simplify IndexOf() by leveraging the splay operation, reducing additional traversal logic and improving overall performance.
This commit Streamlines data type handling by replacing Long with native. It also updates target to ECMAScript 2020. Despite the introduction of bigint, but Long still remains in Counter. We need to remove Long.

1-1: Consider removing the unusedJsonimport.The
Jsontype is imported from '@yorkie-js-sdk/src/document/document' but is not used in this file. To keep the imports clean and avoid potential confusion, consider removing this unused import.Apply this diff to remove the unused import:

10-10: LGTM! Consider adding a comment for clarity.The change to make
selectionoptional improves flexibility inYorkiePresenceobject creation while maintaining type safety. This aligns well with the PR's objective of enhancing document synchronization capabilities.Consider adding a brief comment explaining why
selectionis optional. For example:export type YorkiePresence = { username: string; color: string; // Optional: may be undefined when user has no active selection selection?: TextPosStructRange; };This would provide clarity for other developers working with this type in the future.
packages/sdk/src/util/validator.ts (2)
20-20: Excellent type safety improvement!Changing the parameter type from
anytounknownis a great step towards better type safety. This change aligns with TypeScript best practices and helps prevent potential type-related issues.Consider adding type narrowing within the function to demonstrate proper usage of the
unknowntype. For example:export const validateSerializable = (value: unknown): boolean => { if (value === null || value === undefined) { return true; // null and undefined are valid JSON values } try { const serialized = JSON.stringify(value); return serialized !== undefined; } catch (error) { return false; } };This implementation explicitly handles
nullandundefined, and simplifies the logic by returning the result of the comparison directly.
Line range hint
21-30: Consider optimizing the serializability checkWhile the current implementation works, there are a few areas where it could be improved:
- The check for
serialized === undefinedis unnecessary asJSON.stringifynever returnsundefined.- For large objects, performing a full serialization might be inefficient.
- The function doesn't explicitly handle all cases of non-serializable values.
Consider this alternative implementation:
export const validateSerializable = (value: unknown): boolean => { // Handle primitive types that are always serializable if (value === null || ['undefined', 'boolean', 'number', 'string'].includes(typeof value)) { return true; } // Handle non-serializable types if (['function', 'symbol'].includes(typeof value)) { return false; } // For objects and arrays, we need to check more deeply if (typeof value === 'object') { try { JSON.stringify(value); return true; } catch { return false; } } return false; // Fallback for any unhandled types };This implementation:
- Quickly returns
truefor primitives that are always serializable.- Quickly returns
falsefor types that are never serializable.- Only performs
JSON.stringifyfor objects and arrays, which could potentially contain non-serializable values.- Removes the unnecessary undefined check.
This approach should be more efficient and comprehensive in handling different types of values.

45-46: LGTM: Updated type constraint for stringifyObjectValuesThe change from
objecttoIndexableimproves type safety and aligns with the new import.Consider adding a brief comment explaining the

(implementation) };
58-59: LGTM: Updated type constraint for parseObjectValuesThe change from
objecttoIndexableis consistent with the stringifyObjectValues function and improves type safety.Consider adding a brief comment explaining the
Indexabletype and the return value:/** * `parseObjectValues` returns the JSON parsable string values to the origin states. * @param attrs A record of string key-value pairs. * @returns An object conforming to the Indexable interface with parsed values. */ export const parseObjectValues = <A extends Indexable>( attrs: Record<string, string>, ): A => { // ...

17-59: Summary: Improved type safety with Indexable interfaceThe changes in this file enhance type safety by using the
Indexableinterface forstringifyObjectValuesandparseObjectValuesfunctions. This aligns well with the PR's objective of introducing a version vector system and likely contributes to improved document state handling and synchronization.The modifications are consistent and do not alter the core functionality of the utility functions. They provide a more precise type constraint, which can help catch potential type-related issues earlier in the development process.
Consider documenting the
Indexableinterface in the project's API documentation, explaining its role in the version vector system and how it relates to document synchronization. This will help other developers understand the purpose and usage of these utility functions in the broader context of the SDK.packages/sdk/test/integration/integration_helper.ts (1)
22-22: Consistent use of new generic types.The updates to the document types (
Document<T, P>) in the callback parameters and document creation are consistent with the function signature changes. This maintains type safety throughout the function.For improved readability and consistency, consider using type aliases for
Document<T, P>. For example:type TestDocument<T, P extends Indexable> = Document<T, P>; // Then use it like this: const doc1 = new yorkie.TestDocument<T, P>(docKey); const doc2 = new yorkie.TestDocument<T, P>(docKey);This can make the code more readable, especially if

185-200: Well-implementedtoVersionVectorfunctionThe
toVersionVectorfunction effectively converts aVersionVectorto its Protobuf representation, properly handling the optional input and ensuring correctness in the serialization process.
833-833: Non-null assertion operator may be unnecessaryIn the line:
fromVersionVector(pbChangeID.versionVector)!,Since
fromVersionVectorcan handleundefinedvalues, the non-null assertion!might be redundant. Removing it can enhance code safety.
1515-1519: Avoid unnecessary non-null assertion inversionVectorToHexIn the
versionVectorToHexfunction:const pbVersionVector = toVersionVector(vector)!;Given that
vectoris not optional here, andtoVersionVectorcan returnundefinedonly ifvectorisundefined, the non-null assertion may not be necessary. Consider ensuring thattoVersionVectoralways returns a validPbVersionVectorwhenvectoris provided.
1528-1529: Unnecessary non-null assertion inhexToVersionVectorIn the
hexToVersionVectorfunction:return fromVersionVector(pbVersionVector)!;Since
fromVersionVectorcan returnundefined, it's safer to handle this possibility rather than using the non-null assertion.

555-577: Correct Construction of Recursive Paths inPathOfInternalThe
PathOfInternaltype constructs all possible paths within the JSON structure, using conditional types and recursive calls while respecting the specified depth. This provides comprehensive path typings for nested JSON elements.
1186-1188: Ensure Correct Reapplication of Local Changes After SnapshotWhen a snapshot is applied, local changes are reapplied as remote changes. Verify that reapplying local changes in this manner does not introduce inconsistencies or conflicts within the document state.
1263-1269: Passingthis.getVersionVector()increateChangePackIn the
createChangePackmethod,this.getVersionVector()is passed toChangePack.create(). Ensure thatthis.getVersionVector()always returns a definedVersionVectorto prevent potential issues during change pack creation. If it can beundefined, consider handling this case appropriately.
1341-1349: Updated Garbage Collection UsingVersionVectorThe

Additionally,snapshotVectoris included in the publishedSnapshotevent after serialization. Ensure that the conversion functions (converter.versionVectorToHexandconverter.hexToVersionVector) correctly handleVersionVectorobjects.
1526-1526: Synchronize Local Change ID with Remote ChangeThe call to
this.changeID = this.changeID.syncClocks(change.getID());ensures that the localChangeIDis synchronized with the remote change'sChangeID. This is crucial for maintaining an accurate and consistent version history in collaborative editing scenarios.
1679-1685: HandlingSnapshotEventwithsnapshotVectorinapplyDocEventIn the
applyDocEventmethod, handling ofDocEventType.Snapshotnow includes processing ofsnapshotVector. The method correctly convertsserverSeqandsnapshotVectorfrom strings to their respective types before callingapplySnapshot(). This ensures that snapshots are applied with the correct versioning information.
1892-1900: Implementation offilterVersionVectorMethodThe
filterVersionVectormethod filters out lamport timestamps from detached clients in the version vector. This helps prevent conflicts and inaccuracies caused by clients that are no longer participating. Ensure that this filtering logic aligns with the intended synchronization strategy.

47-47: LGTM: VersionVector conversion implemented correctlyThe new imports and the
toVersionVectorfunction have been implemented correctly. The function properly handles potential undefined input and correctly converts the VersionVector to its Protobuf representation, including the necessary BigInt conversion for large numbers.Also applies to: 82-82, 185-198
166-166: LGTM: ChangeID conversion updated correctlyThe
toChangeIDfunction has been properly updated to include theversionVectorfield, using the newly implementedtoVersionVectorfunction. This change consistently integrates VersionVector into the system.
837-852: LGTM: fromVersionVector implemented correctlyThe
fromVersionVectorfunction correctly converts a Protobuf VersionVector back to the model format, handling undefined input and properly converting BigInt values.
1364-1364: LGTM: ChangePack conversion updated correctlyThe
fromChangePackfunction has been properly updated to include theversionVectorfield, using the newly implementedfromVersionVectorfunction. This change is consistent with the integration of VersionVector throughout the system.
1511-1528: LGTM: VersionVector hex conversion utilities addedThe new utility functions
versionVectorToHexandhexToVersionVectorhave been implemented correctly, providing a way to convert VersionVector to and from a hexadecimal string representation. These functions have also been properly added to theconverterobject.Also applies to: 1662-1663
832-832: 🛠️ Refactor suggestionConsider removing unnecessary non-null assertion
In the
fromChangeIDfunction, the non-null assertion (!) when callingfromVersionVectormay not be necessary, asfromVersionVectoralready returnsundefinedfor undefined input.Consider changing the line to:
-fromVersionVector(pbChangeID.versionVector)!, +fromVersionVector(pbChangeID.versionVector),This change would make the code more robust by allowing
undefinedto be a valid value forversionVector.Likely invalid or redundant comment.

232-236: Addition ofversionVectorfield inChangePackThe
versionVectorfield has been correctly added to theChangePackclass, and its field mapping in thefieldsarray is appropriately specified.Also applies to: 251-251
350-354: Addition ofversionVectorfield inChangeIDThe
versionVectorfield has been appropriately added to theChangeIDclass, with correct implementation in both the class definition and thefieldsmapping.Also applies to: 367-367
387-422: Implementation ofVersionVectorclassThe
VersionVectorclass is properly implemented, including constructor, serialization, and deserialization methods. The class enhances version control capabilities as intended.
394-394: Ensurebigintcompatibility invectorfieldThe
vectorfield usesbigintfor its values. Verify that all target environments support thebiginttype, as it may not be available in older JavaScript runtimes (e.g., browsers before Chrome 67 or Node.js prior to version 10.4.0).Run the following script to check for
bigintusage in the codebase:✅ Verification successful

36-38: Consider documenting version vector conflict resolution strategy.The introduction of version vectors is a good choice for tracking causality. However, consider documenting:
- How conflicts are resolved when concurrent changes are detected
- How this impacts the garbage collection strategy
- Any performance implications of maintaining and synchronizing version vectors
This will help maintainers understand the trade-offs and constraints of the implementation.
