@创建工程

创建空白Vue+TS工程

npm init vue@latest

移植内容

  • src覆盖
  • package.json合并
  • vite.config.js合并
  • src下所有js改名ts
  • 所有vue文件lang=ts

运行起来

npm run dev

@检查TS语法

执行类型检查

npm run type-check

Found 313 errors in 30 files.

允许隐式any

"noImplicitAny": false,

@.ts件重构细节

useScroll.ts

type Scrollable = window | HTMLElement

export default function (target:Scrollable = window, dataRef = null) {...}

const offset = (target as HTMLElement).scrollTop - y;

router/index.ts

路由表类型分配错误

import { createRouter, createWebHistory, type RouteRecordRaw } from "vue-router";

const router = createRouter({
   history: createWebHistory(import.meta.env.BASE_URL),
   routes: ([...publicRoutes] as readonly RouteRecordRaw[]),
});

类型“unknown”上不存在属性“user”。ts(2339)

interface StoreState {
    user:User,
    token:string
}

console.log("beforeEach",(store.state as StoreState).user);

类型“{ path: string; name: string; meta: { menuIndex: string; adminRequired: boolean; }; component: () => Promise<typeof import("d:/GZH5/H5-2207/manager_2207/movie-manats-2207/src/views/cinema/HotCity.vue")>; }”的参数不能赋给类型“RouteRecordName”的参数。ts(2345)

import { type RouteRecordName } from "vue-router";

  adminRoutes.forEach(r => {
     // 未挂载就挂载
     if (!router.hasRoute(<RouteRecordName><unknown>r)) {
        router.addRoute(r);
        console.log(`挂载${r}完毕`);
     } else {
        console.log(`${r}已挂载`);
     }
  });

store/index.ts

类型“unknown”上不存在属性“user”。ts(2339)

   getters: {
      isAdmin(state){
         return (state as StoreState).user && (state as StoreState).user.admin
      }
   },

不能将类型“{ namespaced: boolean; state(): { content: any; }; getters: {}; mutations: { setObj(state: any, content: any): void; }; actions: { fetchContent({ commit, sate }: { commit: any; sate: any; }, arg: any): Promise<void>; }; }”分配给类型“Module<any,unknown>”。

/* 子模块 */
modules: {
  demoModule: (demoModule as any),
},

Found 73 errors in 10 files.

@.vue文件重构细节

NotFound.vue

类型“string | string[]”上不存在属性“join”。 类型“string”上不存在属性“join”。ts(2339)

<p>/{{ ($route.params.pm as string[]).join("/") }}</p>

Playing.vue

类型“{ :ComponentInternalInstance;: ComponentInternalInstance; :ComponentInternalInstance;data: {}; props: Partial<{}> & Omit<Readonly<ExtractPropTypes<{}>> & VNodeProps & AllowedComponentProps & ComponentCustomProps, never>; ... 10 more ...; watch<T extends string | ((...args: any) => any)>(source: T, cb: T extends (...args: any) => infer R ? (args_0: R, args_1: R) => ...”上不存在属性“$store”。ts(2339)

 <!-- 不是管理员就隐藏之 -->
 <el-button
    v-admin
    class="opBtn"
    type="danger"
    @click="patchDelete">
    <el-icon><Close /></el-icon>&nbsp;删除
 </el-button>

属性“replaceAll”在类型“string”上不存在。是否需要更改目标库? 请尝试将 “lib” 编译器选项更改为“es2021”或更高版本。ts(2550)

找不到名称“console”。是否需要更改目标库? 请尝试更改 “lib” 编译器选项以包括 “dom”。ts(2584)

"lib": ["DOM","ES2021"]

不能将类型“{ msg: string; callback: () => void; }”分配给类型“{ msg: string; callback: () => Promise<void>; }”。 在这些类型中，"callback()" 返回的类型不兼容。ts(2322)

/* 批量删除 */
const patchDelete = () => {
   // 确认删除对话框显示粗来
   dialogMode.value = (dialogModes.patchDelete as any);
   dialogVisible.value = true;
};

Coming.vue

不能将类型“{ msg: string; callback: () => void; }”分配给类型“{ msg: string; callback: () => Promise<void>; }”。 在这些类型中，"callback()" 返回的类型不兼容。ts(2322)

/* 批量删除 */
const patchDelete = () => {
	// 确认删除对话框显示粗来
	dialogMode.value = (dialogModes.patchDelete as any);
	refEpDialog.value.setDialogVisible(true);
};

App.vue

不能将unknown类型分配给string

const currentMenuIndex = computed(():string => {
   const result = (route.meta.menuIndex as string);
   console.log("route=", route);
   console.log("currentMenuIndex=", result);
   return result;
});

EpTable.vue

类型“{}”上不存在属性“prop”。ts(2339)

interface EpTableColConfig {
   prop: string;
   label: string;
   fixed: boolean;
   width: number;
   formatter: any;
   hasSlot: boolean;
   nosort: boolean;
}

const { tableData, pageSize, fixedCol, cols, /* colWidth, */ avgColWidth } = defineProps({
	tableData: Array,
	pageSize: Number,
	fixedCol: Object,
	cols: Array<EpTableColConfig>,
	avgColWidth: Number,
});

App.vue

const menu = ref(adminMenu as EpMenuItem[])

DynamicLineChart.vue

类型“number”的参数不能赋给类型“string”的参数。ts(2345)

data.push(5000 + parseInt(Math.random() * 5000 + ""));

BtnGroup.vue

类型“unknown”上不存在属性“type”。ts(2339)

interface GroupBtnConfig 	{
    name: string,
    type: string,
    slotName: string,
    callback: string,
}

const { groupBtns } = defineProps({
	groupBtns: Array<GroupBtnConfig>,
});

EpMenuUnit.vue

类型“unknown”上不存在属性“submenu”。ts(2339)

interface EpMenuItem {
    name:string,
    iconName?:string,
    path?:string,
    submenu?:EpMenuItem[]
}

const { activeIndex, menu, parentIndex } = defineProps({
	activeIndex: String,
	menu: Array<EpMenuItem>,
	parentIndex: String,
});

类型“{}”上不存在属性“runtime”。ts(2339)

interface FilmType {
    name:string,
}

interface Film {
    _id:string,
    filmId:string,
    name:string,
    runtime:string,
    grade:string,
    filmType:FilmType,
    premiereAt:number,
    isPresale:number,
    category:string,
    nation:string,
    actors:string,
    poster:string,
    synopsis:string,
}

interface FormUploadPicture {
    name:string,
    url:string,
}

interface FilmForm extends Film {
    category:string[],
    poster:FormUploadPicture[],
    actors:FormUploadPicture[],
}

// 表单数据存储器
const form = reactive<FilmForm>({} as FilmForm);

@排错摘要

找不到模块“@store/index”或其相应的类型声明。ts(2307)

    "@/*": ["./src/*"],

},

“config.headers”可能为“未定义”。ts(18048)

config.headers!["Authorization"]

“store.state”的类型为“未知”。ts(18046)

config.headers!["Authorization"] = `Bearer ${(store.state as any).token}`;

const { arr: films } = await <doGetResponse>(doGet(`/film/0`) as unknown);

类型“number”的参数不能赋给类型“string”的参数。ts(2345)

var minutesDiffer = parseInt(oddMillis / (60 * 1000) + "");

不能将类型“number”分配给类型“null”。ts(2322)
