function getSyncType(metadata, globalSync?): RepositorySyncType;

Defined in: packages/rxdb/src/sync-contract/sync-type-utils.ts:84

从 EntityMetadata 获取同步类型

Parameters

Parameter	Type	Description
metadata	EntityMetadata	实体元数据
globalSync?	| SyncOptions | EntitySyncResolver	全局同步配置（可选，作为回退）；传实例解析器 rxdb.entitySync 时连同实例覆盖一起解析

Returns

RepositorySyncType

同步类型

Example

// Full sync (双向同步)
const metadata = {
  sync: {
    type: SyncType.Full,
    local: { adapter: 'sqlite' },
    remote: `{ adapter: 'supabase' }`
  }
};
getSyncType(metadata); // 'full'

// Remote only (只读远程)
const metadata = {
  sync: {
    type: SyncType.None,
    remote: `{ adapter: 'supabase' }`
  }
};
getSyncType(metadata); // 'remote'

// Local only (只本地)
const metadata = {
  sync: {
    type: SyncType.None,
    local: `{ adapter: 'sqlite' }`
  }
};
getSyncType(metadata); // 'local'

// No sync (系统表)
const metadata = { sync: undefined };
getSyncType(metadata); // 'none'

// 使用全局配置回退
const metadata = { sync: undefined };
const globalSync = { type: SyncType.Full, local: {...}, remote: {...} };
getSyncType(metadata, globalSync); // 'full'
