# Стратегии кэширования SFERA
|
||
|
||
## 🎯 Обзор
|
||
|
||
Комплексная система кэширования для платформы SFERA, обеспечивающая высокую производительность, снижение нагрузки на внешние API и улучшение пользовательского опыта за счет оптимального кэширования данных различных типов.
|
||
|
||
## 📊 Архитектура кэширования

```
|
||
|
||
## 🔄 Уровни кэширования
|
||
|
||
### 1. Browser/Client Cache
|
||
|
||
#### HTTP Cache Headers
|
||
|
||
```typescript
|
||
// src/lib/cache-headers.ts
|
||
export const CacheHeaders = {
|
||
// Статические ресурсы (изображения, CSS, JS)
|
||
static: {
|
||
'Cache-Control': 'public, max-age=31536000, immutable', // 1 год
|
||
Expires: new Date(Date.now() + 31536000 * 1000).toUTCString(),
|
||
},
|
||
|
||
// API данные (редко изменяются)
|
||
longTerm: {
|
||
'Cache-Control': 'public, max-age=3600, s-maxage=3600', // 1 час
|
||
ETag: true,
|
||
Vary: 'Accept-Encoding',
|
||
},
|
||
|
||
// API данные (часто изменяются)
|
||
shortTerm: {
|
||
'Cache-Control': 'public, max-age=300, s-maxage=300', // 5 минут
|
||
ETag: true,
|
||
},
|
||
|
||
// Приватные данные пользователя
|
||
private: {
|
||
'Cache-Control': 'private, max-age=300', // 5 минут, только браузер
|
||
ETag: true,
|
||
},
|
||
|
||
// Динамические данные (не кэшировать)
|
||
noCache: {
|
||
'Cache-Control': 'no-cache, no-store, must-revalidate',
|
||
Pragma: 'no-cache',
|
||
Expires: '0',
|
||
},
|
||
}
|
||
|
||
// Middleware для установки заголовков кэширования
|
||
export const setCacheHeaders = (type: keyof typeof CacheHeaders) => {
|
||
return (res: NextResponse) => {
|
||
const headers = CacheHeaders[type]
|
||
|
||
Object.entries(headers).forEach(([key, value]) => {

||

||
})
|

|

|

### 3. Application-Level Caching
|

#### Memory Cache с LRU
|

```typescript

## 🎯 Best Practices
|
||
|
||
### 1. Кэширование GraphQL
|
||
|
||
```typescript
|
||
// src/lib/graphql-cache.ts
|
||
export const GraphQLCacheConfig = {
|
||
// Кэш по умолчанию для запросов
|
||
defaultMaxAge: 300, // 5 минут
|
||
|
||
// Специфичные настройки для разных типов
|
||
typeConfigs: {
|
||
User: { maxAge: 1800 }, // 30 минут
|
||
Organization: { maxAge: 3600 }, // 1 час
|
||
Product: { maxAge: 600 }, // 10 минут
|
||
Order: { maxAge: 300 }, // 5 минут
|
||
Warehouse: { maxAge: 86400 }, // 24 часа
|
||
},
|
||
|
||
// Поля, которые не должны кэшироваться
|
||
skipCache: ['currentUser', 'realtimeData', 'sensitiveInformation'],
|
||
}
|
||
|
||
// Директива для кэширования в GraphQL схеме
|
||
export const cacheDirective = `
|
||
directive @cache(
|
||
maxAge: Int = 300
|
||
scope: CacheScope = PUBLIC
|
||
) on FIELD_DEFINITION | OBJECT
|
||
|
||
enum CacheScope {
|
||
PUBLIC
|
||
PRIVATE
|
||
}
|
||
`
|
||
```
|
||
|
||
### 2. Кэширование компонентов React
|
||
|
||
```typescript
|
||
// src/hooks/useCache.ts
|
||
import { useCallback, useEffect, useState } from 'react'
|
||
import { redis } from '@/lib/redis'
|
||
|
||
export const useCache = <T>(
|
||
key: string,
|
||
fetcher: () => Promise<T>,
|
||
ttl: number = 300
|
||
) => {
|
||
const [data, setData] = useState<T | null>(null)
|
||
const [loading, setLoading] = useState(true)
|
||
const [error, setError] = useState<Error | null>(null)
|
||
|
||
const fetchData = useCallback(async () => {
|
||
try {
|
||
setLoading(true)
|
||
setError(null)
|
||
|
||
// Попытка получить из кэша
|
||
const cached = await redis.get<T>(key)
|
||
|
||
if (cached) {
|
||
setData(cached)
|
||
setLoading(false)
|
||
return
|
||
}
|
||
|
||
// Получение свежих данных
|
||
const fresh = await fetcher()
|
||
|
||
// Сохранение в кэш
|
||
await redis.set(key, fresh, ttl)
|
||
|
||
setData(fresh)
|
||
} catch (err) {
|
||
setError(err as Error)
|
||
} finally {
|
||
setLoading(false)
|
||
}
|
||
}, [key, fetcher, ttl])
|
||
|
||
useEffect(() => {
|
||
fetchData()
|
||
}, [fetchData])
|
||
|
||
const invalidate = useCallback(async () => {
|
||
await redis.del(key)
|
||
await fetchData()
|
||
}, [key, fetchData])
|
||
|
||
return {
|
||
data,
|
||
loading,
|
||
error,
|
||
invalidate,
|
||
refetch: fetchData
|
||
}
|
||
}
|
||
|
||
// Пример использования
|
||
export const OrganizationProfile = ({ organizationId }: { organizationId: string }) => {
|
||
const { data: organization, loading, error } = useCache(
|
||
`org:${organizationId}`,
|
||
() => fetch(`/api/organizations/${organizationId}`).then(r => r.json()),
|
||
3600 // 1 час
|
||
)
|
||
|
||
if (loading) return <div>Loading...</div>
|
||
if (error) return <div>Error: {error.message}</div>
|
||
|
||
return <div>{organization?.name}</div>
|
||
}
|
||
```
|
||
|
||
## 🎯 Заключение
|
||
|
||
Система кэширования SFERA обеспечивает:
|
||
|
||
1. **Многоуровневое кэширование**: От браузера до базы данных
|
||
2. **Интеллектуальная инвалидация**: Автоматическая очистка устаревших данных
|
||
3. **Оптимизация API**: Снижение нагрузки на внешние сервисы
|
||
4. **Мониторинг производительности**: Контроль эффективности кэша
|
||
5. **Автоматическое восстановление**: Самодиагностика и исправление проблем
|
||
|
||
Правильно настроенная система кэширования значительно улучшает производительность приложения и снижает затраты на внешние API.
