移动端离线支持

概述

设计离线优先的移动应用程序，无论网络连接状况如何，都能提供无缝的用户体验。

适用场景

构建无需互联网连接即可工作的应用
实现网络恢复时的无缝同步
处理设备与服务器之间的数据冲突
通过智能缓存减少服务器负载
利用本地存储提升应用响应速度

快速开始

最小工作示例：

import AsyncStorage from '@react-native-async-storage/async-storage';
import NetInfo from '@react-native-community/netinfo';

class StorageManager {
  static async saveItems(items) {
    try {
      await AsyncStorage.setItem(
        'items_cache',
        JSON.stringify({ data: items, timestamp: Date.now() })
      );
    } catch (error) {
      console.error('Failed to save items:', error);
    }
  }

  static async getItems() {
    try {
      const data = await AsyncStorage.getItem('items_cache');
      return data ? JSON.parse(data) : null;
    } catch (error) {
      console.error('Failed to retrieve items:', error);
      return null;
    }
  }

Overview

Design offline-first mobile applications that provide seamless user experience regardless of connectivity.

When to Use

Building apps that work without internet connection
Implementing seamless sync when connectivity returns
Handling data conflicts between device and server
Reducing server load with intelligent caching
Improving app responsiveness with local storage

Quick Start

Minimal working example:

import AsyncStorage from '@react-native-async-storage/async-storage';
import NetInfo from '@react-native-community/netinfo';

class StorageManager {
  static async saveItems(items) {
    try {
      await AsyncStorage.setItem(
        'items_cache',
        JSON.stringify({ data: items, timestamp: Date.now() })
      );
    } catch (error) {
      console.error('Failed to save items:', error);
    }
  }

  static async getItems() {
    try {
      const data = await AsyncStorage.getItem('items_cache');
      return data ? JSON.parse(data) : null;
    } catch (error) {
      console.error('Failed to retrieve items:', error);
      return null;
    }
  }

Best Practices

✅ DO

Implement robust local storage
Use automatic sync when online
Provide visual feedback for offline status
Queue actions for later sync
Handle conflicts gracefully
Cache frequently accessed data
Implement proper error recovery
Test offline scenarios thoroughly
Use compression for large data
Monitor storage usage

❌ DON'T

Assume constant connectivity
Sync large files frequently
Ignore storage limitations
Force unnecessary syncing
Lose data on offline mode
Store sensitive data unencrypted
Accumulate infinite queue items
Ignore sync failures silently
Sync in tight loops
Deploy without offline testing
