ConflictResolver

Defined in: packages/rxdb/src/sync-contract/conflict.ts:72

冲突解决器接口

可自定义实现。注意运行时能自动应用的解决结果只有 KEEP_LOCAL 与 KEEP_REMOTE， 返回 MERGE / DEFER 会让本轮拉取整体回滚，详见 ConflictResolution。

通过 PullOptions.conflictResolver 或 PullRepositoryOptions.conflictResolver 传入；不传则用 LWWConflictResolver。

Example

交互式选择（返回值仍须落在两种可应用结果上）

class MyResolver implements ConflictResolver {
  async resolve(conflict: Conflict): Promise<ConflictResolution> {
    const keepLocal = await showConflictDialog(conflict);
    return { type: keepLocal ? 'KEEP_LOCAL' : 'KEEP_REMOTE' };
  }
}
