decorator

装饰器模式 - 动态地给对象添加额外的职责。

函数签名

function decorate<T>(fn: T, decorators: Decorator<T>[]): T

function withLogging(logger): Decorator
function withTiming(logger): Decorator
function withCache(): Decorator
function withErrorHandling(handler): Decorator
function withRetry(maxRetries, delay, setTimeout): Decorator

使用示例

import { decorate, withLogging, withCache } from 'zcw-shared/functions/patterns/decorator'

function add(a: number, b: number) {
  return a + b
}

const enhanced = decorate(add, [
  withLogging(console.log),
  withCache()
])

enhanced(1, 2)  // 记录日志并缓存结果
