About this skill

Variant 类型系统

统一管理组件视觉变体类型的规范，使用 VARIANT_TYPES 常量和 Enum 工具。

常量定义

定义在 src/constants/variant.ts：

export const VARIANT_TYPES = [
  "primary",
  "success",
  "warning",
  "danger",
  "info",
] as const;

export type VariantType = (typeof VARIANT_TYPES)[number];
export const VARIANT_DEFAULT = "info";

export const VARIANT_ICON_MAP: Record<string, string> = {
  primary: "circle-info",
  success: "circle-check",
  info: "circle-info",
  warning: "triangle-exclamation",
  danger: "circle-xmark",
  error: "circle-xmark",
};

Enum 工具

导入路径：@utils/Enum

import { Enum } from "@utils/Enum";

// 传入数组
Enum(VARIANT_TYPES)  // 返回数组本身

// 传入多个参数
Enum("a", "b", "c")  // 返回 ["a", "b", "c"]

Enum() 本质是标识函数，让 @attribute 的 type 字段区分枚举类型和普通构造器。

使用方式

基础用法

import { Enum } from "@utils/Enum";
import { VARIANT_TYPES, VARIANT_DEFAULT, type VariantType } from "@constants/variant";

@attribute({
  type: Enum(VARIANT_TYPES),
  default: VARIANT_DEFAULT,
  observer(this: EaAlert, newVal: VariantType) {
    this.updateContainerClasslist();
  },
})
variant: VariantType = VARIANT_DEFAULT;

扩展 variant 值

@attribute({
  type: Enum([...VARIANT_TYPES, "normal"]),
  default: "normal",
  observer(this: EaComponent) {
    this.updateContainerClasslist();
  },
})
variant: VariantType | "normal" = "normal";

自定义枚举（非 variant）

@attribute({
  type: Enum(["outline", "solid", "dashed"]),
  default: "solid",
})
borderStyle: string = "solid";

命名规则

  • 属性名统一为 variant：用于表示组件视觉变体/类型的属性，不使用 type
  • 统一使用 danger：作为错误类型，不使用 error（VARIANT_ICON_MAP 中保留 error 做兼容映射）
  • 可选值：primary, success, warning, danger, info

与 BEM 配合

updateContainerClasslist(): string {
  const className = bem(
    { [this.variant]: true },
    { disabled: this.disabled }
  );
  this._container.className = className;
  return className;
}

@include block($name) {
  @include modifier(primary) {
    background-color: var(--primary-color);
  }

  @include modifier(success) {
    background-color: var(--green-500);
  }

  @include modifier(danger) {
    background-color: var(--red-500);
  }
}

图标映射

使用 VARIANT_ICON_MAP 获取 variant 对应的图标名：

import { VARIANT_ICON_MAP } from "@constants/variant";

const iconName = VARIANT_ICON_MAP[this.variant]; // 如 "circle-check"
