版本
react & react-dom ^18.2.0
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
husky ^8.0.3
lint-staged ^13.1.2
prettier 2.8.4
json-server 0.17.2
craco-less ^2.0.0
@craco/craco ^7.1.0
qs ^6.11.0
dayjs ^1.11.7
react-helmet ^6.1.0
@types/react-helmet ^6.1.6
react-query ^6.1.0
@welldone-software/why-did-you-render ^7.0.1
@emotion/react & @emotion/styled ^11.10.6

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

1~3

4.添加任务搜索功能

接下来为任务看板添加搜索功能

编辑 src\screens\ViewBoard\utils.ts(新增 useTasksSearchParams 为后续 SearchPanel 中数据联动做准备):

js 复制代码
import { useMemo } from "react";
import { useLocation } from "react-router";
import { useProject } from "utils/project";
import { useUrlQueryParam } from "utils/url";

...
export const useTasksSearchParams = () => {
  const [param, setParam] = useUrlQueryParam([
    "name",
    "typeId",
    "processorId",
    "tagId",
  ]);
  const projectId = useProjectIdInUrl();
  return useMemo(
    () => ({
      projectId,
      typeId: Number(param.typeId) || undefined,
      processorId: Number(param.processorId) || undefined,
      tagId: Number(param.tagId) || undefined,
      name: param.name,
    }),
    [projectId, param]
  );
};
...

新建 src\components\task-type-select.tsx(仿照 UserSelect 改造出一个 TaskTypeSelect):

js 复制代码
import { useTaskTypes } from "utils/task-type";
import { IdSelect } from "./id-select";

export const TaskTypeSelect = (props: React.ComponentProps<typeof IdSelect>) => {
  const { data: taskTypes } = useTaskTypes();
  return <IdSelect options={taskTypes || []} {...props} />;
};

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

js 复制代码
import { useSetUrlSearchParam } from "utils/url"
import { useTasksSearchParams } from "../utils"
import { Row } from "components/lib"
import { Button, Input } from "antd"
import { UserSelect } from "components/user-select"
import { TaskTypeSelect } from "components/task-type-select"

export const SearchPanel = () => {
  const searchParams = useTasksSearchParams()
  const setSearchParams = useSetUrlSearchParam()
  const reset = () => {
    setSearchParams({
      typeId: undefined,
      processorId: undefined,
      tagId: undefined,
      name: undefined
    })
  }
  return <Row marginBottom={4} gap={true}>
    <Input style={{width: '20rem'}} placeholder='任务名' value={searchParams.name}
      onChange={e => setSearchParams({name: e.target.value})}/>
    <UserSelect defaultOptionName="经办人" value={searchParams.processorId}
      onChange={val => setSearchParams({processorId: val})}/>
    <TaskTypeSelect defaultOptionName="类型" value={searchParams.typeId}
      onChange={val => setSearchParams({typeId: val})}/>
    <Button onClick={reset}>清除筛选器</Button>
  </Row>
}

编辑 src\screens\ViewBoard\index.tsx(引入 SearchPanel):

js 复制代码
...
import { SearchPanel } from "./components/SearchPanel";

export const ViewBoard = () => {
  ...
  return (
    <div>
      <h1>{currentProject?.name}看板</h1>
      <SearchPanel/>
      <ColumnsContainer>...</ColumnsContainer>
    </div>
  );
};
...

查看功能和效果:

5.优化看板样式

功能实现一部分了,接下来优化样式

编辑 src\components\lib.tsx(新增 ViewContainer 处理内边距):

js 复制代码
export const ViewContainer = styled.div`
  padding: 3.2rem;
  width: 100%;
  display: flex;
  flex-direction: column;
`

编辑 src\authenticated-app.tsx(调整 Main 样式,垂直占满):

js 复制代码
...
const Main = styled.main`
  display: flex;
  /* overflow: hidden; */
`;

编辑 src\screens\ViewBoard\index.tsx(应用 ViewContainer ,增加 Loading 调整 ColumnsContainer 样式并暴露出来,使其触底):

js 复制代码
...
import { useProjectInUrl, useTasksSearchParams, useViewBoardSearchParams } from "./utils";
...
import { ViewContainer } from "components/lib";
import { useTasks } from "utils/task";
import { Spin } from "antd";

export const ViewBoard = () => {
  ...
  const { data: viewboards, isLoading: viewBoardIsLoading } = useViewboards(useViewBoardSearchParams());
  const { isLoading: taskIsLoading } = useTasks(useTasksSearchParams())
  const isLoading = taskIsLoading || viewBoardIsLoading
  return (
    <ViewContainer>
      <h1>{currentProject?.name}看板</h1>
      <SearchPanel />
      {
        isLoading ? <Spin/> : <ColumnsContainer>
        ...
        </ColumnsContainer>
      }
    </ViewContainer>
  );
};

const ColumnsContainer = styled.div`
  display: flex;
  overflow-x: scroll;
  flex: 1;
`;

编辑 src\screens\ProjectDetail\index.tsx(引入 Menu 并调整整个组件样式,Menu 高亮状态从路由中获取):

js 复制代码
import { Link, Navigate } from "react-router-dom";
import { Route, Routes, useLocation } from "react-router";
import { TaskGroup } from "screens/TaskGroup";
import { ViewBoard } from "screens/ViewBoard";
import styled from "@emotion/styled";
import { Menu } from "antd";

const useRouteType = () => {
  const pathEnd = useLocation().pathname.split('/')
  return pathEnd[pathEnd.length - 1]
}

export const ProjectDetail = () => {
  const routeType = useRouteType()

  return (
    <Container>
      <Aside>
        <Menu mode="inline" selectedKeys={[routeType]}>
          <Menu.Item key='viewboard'>
            <Link to="viewboard">看板</Link>
          </Menu.Item>
          <Menu.Item key='taskgroup'>
            <Link to="taskgroup">任务组</Link>
          </Menu.Item>
        </Menu>
      </Aside>
      <Main>
        <Routes>
          <Route path="/viewboard" element={<ViewBoard />} />
          <Route path="/taskgroup" element={<TaskGroup />} />
          <Route index element={<Navigate to="viewboard" replace />} />
        </Routes>
      </Main>
    </Container>
  );
};

const Aside = styled.aside`
  background-color: rgb(244, 245, 247);
  display: flex;
`

const Main = styled.div`
  display: flex;
  box-shadow: -5px 0 5px -5px rgbs(0, 0, 0, 0.1);
  overflow: hidden;
`

const Container = styled.div`
  display: grid;
  grid-template-columns: 16rem 1fr;
  width: 100%;
`

查看功能和效果:

6.创建看板与任务

接下来新建创建看板的组件:

先准备好调用新增看板接口的 Hook,编辑 src\utils\viewboard.ts

js 复制代码
...
export const useAddViewboard = (queryKey: QueryKey) => {
  const client = useHttp();
  return useMutation(
    (params: Partial<Viewboard>) =>
      client(`kanbans`, {
        method: "POST",
        data: params,
      }),
    useAddConfig(queryKey)
  );
};

新建组件:src\screens\ViewBoard\components\CreateViewboard.tsx

js 复制代码
import { useState } from "react"
import { useProjectIdInUrl, useViewBoardQueryKey } from "../utils"
import { useAddViewboard } from "utils/viewboard"
import { Input } from "antd"
import { Container } from "./ViewboardCloumn"

export const CreateViewBoard = () => {
  const [name, setName] = useState('')
  const projectId = useProjectIdInUrl()
  const { mutateAsync: addViewBoard } = useAddViewboard(useViewBoardQueryKey())

  const submit = async () => {
    await addViewBoard({name, projectId})
    setName('')
  }

  return <Container>
    <Input
      size="large"
      placeholder="新建看板名称"
      onPressEnter={submit}
      value={name}
      onChange={evt => setName(evt.target.value)}
    />
  </Container>
}

编辑:src\screens\ViewBoard\index.tsx(引入 CreateViewBoard):

js 复制代码
...
import { CreateViewBoard } from "./components/CreateViewboard";

export const ViewBoard = () => {
  ...
  return (
    <ViewContainer>
      ...
      {
        isLoading ? <Spin/> : <ColumnsContainer>
          {viewboards?.map((vbd) => (
            <ViewboardColumn viewboard={vbd} key={vbd.id} />
          ))}
          <CreateViewBoard/>
        </ColumnsContainer>
      }
    </ViewContainer>
  );
};
...

查看功能和效果,输入新增看板名后回车,即可看到新看板:

接下来新建创建任务的组件:

先准备好调用新增任务接口的 Hook,编辑 src\utils\task.ts

js 复制代码
...
import { QueryKey, useMutation, useQuery } from "react-query";
import { useAddConfig } from "./use-optimistic-options";

...
export const useAddTask = (queryKey: QueryKey) => {
  const client = useHttp();
  return useMutation(
    (params: Partial<Task>) =>
      client(`tasks`, {
        method: "POST",
        data: params,
      }),
    useAddConfig(queryKey)
  );
};

新建组件:src\screens\ViewBoard\components\CreateTask.tsx

js 复制代码
import { useEffect, useState } from "react";
import { useProjectIdInUrl, useTasksQueryKey } from "../utils";
import { Card, Input } from "antd";
import { useAddTask } from "utils/task";

export const CreateTask = ({kanbanId}: {kanbanId: number}) => {
  const [name, setName] = useState("");
  const { mutateAsync: addTask } = useAddTask(useTasksQueryKey());
  const projectId = useProjectIdInUrl();
  const [inputMode, setInputMode] = useState(false)

  const submit = async () => {
    await addTask({ name, projectId, kanbanId });
    setName("");
    setInputMode(false)
  };

  const toggle = () => setInputMode(mode => !mode)

  useEffect(() => {
    if (!inputMode) {
      setName('')
    }
  }, [inputMode])
  
  if (!inputMode) {
    return <div onClick={toggle}>+创建任务</div>
  }

  return (
    <Card>
      <Input
        onBlur={toggle}
        placeholder="需要做些什么"
        autoFocus={true}
        onPressEnter={submit}
        value={name}
        onChange={(evt) => setName(evt.target.value)}
      />
    </Card>
  );
};

编辑:src\screens\ViewBoard\components\ViewboardCloumn.tsx(引入 CreateTask):

js 复制代码
...
import { CreateTask } from "./CreateTask";

...
export const ViewboardColumn = ({ viewboard }: { viewboard: Viewboard }) => {
  ...
  return (
    <Container>
      <h3>{viewboard.name}</h3>
      <TasksContainer>
        ...
        <CreateTask kanbanId={viewboard.id}/>
      </TasksContainer>
    </Container>
  );
};
...

查看功能和效果,点击 +创建任务 输入框出现,点击输入框以外的地方输入框隐藏,输入新增任务名后回车,即可看到新任务:
