array enum 的准替代方案(改进版)

定义类

interface Item {
  value: number;
  label: string;
  [x: string]: any;
}

abstract class Enum {
  public static states: readonly Item[]

  public static make () {
    const res: any = {}
    this.states.forEach(v => {
      res[v.value] = v as Item
    })
    return res
  }

  public static value: () => Record<typeof this.states[number]['value'], Item> = Enum.make
}

实际类

class CPUEnum extends Enum {
  public static states = [
    {
      value: 0,
      label: 'intel',
      title: 'intel i11'
    }
  ] as const // 必须加 as const 否则提示出不来

  public static value: () => Record<typeof this.states[number]['value'], Item> // 有大神看到，帮忙提建议优化
}

测试效果

console.info(CPUEnum.value()[0])

结语

1. 初步实现了数组枚举 ts 代码提示
2. 无法实现自动填充 value
