react-router & react-router-dom ^6.11.2
antd ^4.24.8
@commitlint/cli & @commitlint/config-conventional ^17.4.4
eslint-config-prettier ^8.6.0

具体配置、操作和内容会有差异,“坑”也会有所不同。。。


一、项目起航:项目初始化与配置

二、React 与 Hook 应用:实现项目列表

三、TS 应用:JS神助攻 - 强类型

四、JWT、用户认证与异步请求


五、CSS 其实很简单 - 用 CSS-in-JS 添加样式


六、用户体验优化 - 加载中和错误状态处理



七、Hook,路由,与 URL 状态管理



八、用户选择器与项目编辑功能


九、深入React 状态管理与Redux机制





十、用 react-query 获取数据,管理缓存


十一、看板页面及任务组页面开发

1.看板列表开发准备工作

之前的项目详情进入看板页的路由有个小问题,点击浏览器返回按钮回不去,原因如下:

  • 路由列表是栈结构,每访问一个路由都会 push 一个新路由进去,当点击返回,就会将上一个路由置于栈顶;而进入项目详情页(从'projects''projects/1')默认重定向子路由是看板页(projects/1/viewboard),返回上一个路由时,默认又会重定向到看板页路由。列表栈示例如下:
  • ['projects', 'projects/1', 'projects/1/viewboard']

接下来解决一下这个问题,编辑 src\screens\ProjectDetail\index.tsx (重定向标签新增属性 replace,在重定向时直接替换原路由):

...
export const ProjectDetail = () => {
    
    
  return (
    <div>
      ...
      <Routes>
        ...
        <Route index element={
    
    <Navigate to="viewboard" replace/>} />
      </Routes>
    </div>
  );
};

为了方便后续类型统一调用,将 src\screens\ProjectList\components\List.tsxinterface Project 提取到 src\types 目录下

视频中 是用 WebStorm ,博主用的是 VSCode:

  • 在需要重构的变量上右击,选择重构(快捷键 Ctrl + Shift + R),选择 Move to a new file,默认同变量名的文件会创建在当前文件所在同一级目录下,其他引用位置也相应改变,涉及引用位置:
    • src\utils\project.ts
    • src\screens\ProjectList\components\SearchPanel.tsx
    • src\screens\ProjectList\components\List.tsx
  • 拖动新生成的文件到 src\types 目录下,可以看到其他引用位置也相应改变

src\screens\ProjectList\components\SearchPanel.tsxinterface User 也执行同样操作,涉及引用位置:

  • src\screens\ProjectList\components\SearchPanel.tsx
  • src\screens\ProjectList\components\List.tsx
  • src\auth-provider.ts
  • src\context\auth-context.tsx
  • src\utils\use-users.ts

看板页还需要以下两个类型,新建一下:

  • src\types\Viewboard.ts:
export interface Viewboard {
    
    
  id: number;
  name: string;
  projectId: number;
}
  • src\types\Task.ts
export interface Task {
    
    
  id: number;
  name: string;
  projectId: number;
  processorId: number; // 经办人
  taskGroupId: number; // 任务组
  kanbanId: number;
  typeId: number;      // bug or task
  note: string;
}

接下来创建数据请求的 hook:

src\utils\viewboard.ts:

import {
    
     cleanObject } from "utils";
import {
    
     useHttp } from "./http";
import {
    
     Viewboard } from "types/Viewboard";
import {
    
     useQuery } from "react-query";

export const useViewboards = (param?: Partial<Viewboard>) => {
    
    
  const client = useHttp();

  return useQuery<Viewboard[]>(["viewboards", param], () =>
    client("kanbans", {
    
     data: cleanObject(param || {
    
    }) })
  );
};

src\utils\task.ts:

import {
    
     cleanObject } from "utils";
import {
    
     useHttp } from "./http";
import {
    
     Task } from "types/Task";
import {
    
     useQuery } from "react-query";

export const useTasks = (param?: Partial<Task>) => {
    
    
  const client = useHttp();

  return useQuery<Task[]>(["tasks", param], () =>
    client("tasks", {
    
     data: cleanObject(param || {
    
    }) })
  );
};

2.看板列表初步开发

接下来开始开发看板列表,展示需要用到项目数据,可以提取一个从 url 获取 projectId,再用 id 获取项目数据的 hook

新建 src\screens\ViewBoard\utils.ts

import {
    
     useLocation } from "react-router"
import {
    
     useProject } from "utils/project"

export const useProjectIdInUrl = () => {
    
    
  const {
    
     pathname } = useLocation()
  const id = pathname.match(/projects\/(\d+)/)?.[1]
  return Number(id)
}

export const useProjectInUrl = () => useProject(useProjectIdInUrl())

export const useViewBoardSearchParams = () => ({
    
    projectId: useProjectIdInUrl()})

export const useViewBoardQueryKey = () => ['viewboards', useViewBoardSearchParams()]

export const useTasksSearchParams = () => ({
    
    projectId: useProjectIdInUrl()})

export const useTasksQueryKey = () => ['tasks', useTasksSearchParams()]

注意:每一个 useXXXQueryKey 都要确保返回值第一项 与后续列表请求 useXXXuseQuery 的第一个参数保持一致,否则后续增删改都无法正常自动重新请求列表,问题排查比较困难

为看板定制一个展示列组件(任务列表),供每个类型来使用

新建 src\screens\ViewBoard\components\ViewboardCloumn.tsx

import {
    
     Viewboard } from "types/Viewboard";
import {
    
     useTasks } from "utils/task";
import {
    
     useTasksSearchParams } from "../utils";

export const ViewboardColumn = ({
     
     viewboard}:{
     
     viewboard: Viewboard}) => {
    
    
  const {
    
     data: allTasks } = useTasks(useTasksSearchParams())
  const tasks = allTasks?.filter(task => task.kanbanId === viewboard.id)
  return <div>
    <h3>{
    
    viewboard.name}</h3>
    {
    
    
      tasks?.map(task => <div key={
    
    task.id}>{
    
    task.name}</div>)
    }
  </div>
}

编辑 src\screens\ViewBoard\index.tsx

import {
    
     useDocumentTitle } from "utils";
import {
    
     useViewboards } from "utils/viewboard";
import {
    
     useProjectInUrl, useViewBoardSearchParams } from "./utils";
import {
    
     ViewboardColumn } from "./components/ViewboardCloumn"
import styled from "@emotion/styled";

export const ViewBoard = () => {
    
    
  useDocumentTitle('看板列表')

  const {
    
    data: currentProject} = useProjectInUrl()
  const {
    
    data: viewboards, } = useViewboards(useViewBoardSearchParams())

  return <div>
    <h1>{
    
    currentProject?.name}看板</h1>
    <ColumnsContainer>
    {
    
    
      viewboards?.map(vbd => <ViewboardColumn viewboard={
    
    vbd} key={
    
    vbd.id}/>)
    }
    </ColumnsContainer>
  </div>;
};

const ColumnsContainer = styled.div`
  display: flex;
  overflow: hidden;
  margin-right: 2rem;
`

通过代码可知:viewboards.map 后 ViewboardColumn 渲染多次,其中 useTasks 也同时执行多次,但是仔细看浏览器开发者工具可发现,相应请求并没有执行多次,而是只执行了一次,这是因为 react-query 的缓存机制(默认两秒内发送的多个key相同且的参数相同的请求只执行最后一次)

访问看板列表可看到如下内容且三种状态任务横向排列即为正常:

待完成
管理登录界面开发

开发中
管理注册界面开发
权限管理界面开发
UI开发
自测

已完成
单元测试
性能优化

3.添加task, bug 图标

任务的类型接口并不直接返回,而是只返回一个 typeId,并不能明确标识任务类型,需要单独访问接口来获取具体任务类型

新建 src\types\TaskType.ts

export interface TaskType {
    
    
  id: number;
  name: string;
}

新建 src\utils\task-type.ts

import {
    
     useHttp } from "./http";
import {
    
     useQuery } from "react-query";
import {
    
     TaskType } from "types/TaskType";

export const useTaskTypes = () => {
    
    
  const client = useHttp();

  return useQuery<TaskType[]>(["taskTypes"], () =>
    client("tasks")
  );
};

将以下两个 svg 文件拷贝到 src\assets

                </g>
            </g>
        </g>
    </g>

直接使用可能会有如下报错:

Compiled with problems:X

ERROR in ./src/assets/task.svg

Module build failed (from ./node_modules/@svgr/webpack/lib/index.js):
SyntaxError: unknown file: Namespace tags are not supported by default. React's JSX doesn't support namespace tags. You can set `throwIfNamespace: false` to bypass this warning.

skety:type 这种类型的标签属性改成 sketchType 驼峰这样才能被 JSX 接受。

svg 文件 修改后的源码如下:

编辑 src\screens\ViewBoard\components\ViewboardCloumn.tsx(引入图标,并美化):

import {
    
     Viewboard } from "types/Viewboard";
import {
    
     useTasks } from "utils/task";
import {
    
     useTasksSearchParams } from "../utils";
import {
    
     useTaskTypes } from "utils/task-type";
import taskIcon from "assets/task.svg";
import bugIcon from "assets/bug.svg";
import styled from "@emotion/styled";
import {
    
     Card } from "antd";

const TaskTypeIcon = ({
     
      id }: {
     
      id: number }) => {
    
    
  const {
    
     data: taskTypes } = useTaskTypes();
  const name = taskTypes?.find((taskType) => taskType.id === id)?.name;
  if (!name) {
    
    
    return null;
  }
  return <img alt='task-icon' src={
    
    name === "task" ? taskIcon : bugIcon} />;
};

export const ViewboardColumn = ({
     
      viewboard }: {
     
      viewboard: Viewboard }) => {
    
    
  const {
    
     data: allTasks } = useTasks(useTasksSearchParams());
  const tasks = allTasks?.filter((task) => task.kanbanId === viewboard.id);
  return (
    <Container>
      <h3>{
    
    viewboard.name}</h3>
      <TasksContainer>
        {
    
    tasks?.map((task) => (
          <Card style={
    
    {
    
    marginBottom: '0.5rem'}} key={
    
    task.id}>
            <div>{
    
    task.name}</div>
            <TaskTypeIcon id={
    
    task.id} />
          </Card>
        ))}
      </TasksContainer>
    </Container>

};

export const Container = styled.div`
  min-width: 27rem;
  border-radius: 6px;
  background-color: rgb(244, 245, 247);
  display: flex;
  flex-direction: column;

const TasksContainer = styled.div`
  overflow: scroll;
  flex: 1;
  ::-webkit-scrollbar {
