• 公共组件不能有副作用
• 判空操作符替代对象属性判断

    get('/home/datamgr/v2/system_config?configName=DATAMGR, {}).then((res) => {
      const data = (res && res.data) || {};
      store.set('houseHoldBindMode', data.data);
    });

    get('/home/datamgr/v2/system_config?configName=DATAMGR,GRID', {}).then((res) => {
      const data = res?.data?.data || {};
      store.set('houseHoldBindMode', data.DATAMGR_BUIDLING_HOUSE_BIND_MODE);
      store.set('isDutyGird', !!Number(data.DATAMGR_PATROL_FILTER_BY_DUTY_GRID));
    });

• switch代替冗杂的if判断

  const controlShowBySwitchChange = (flag) => {
    form.validateFields().then((values) => {
      const { displayFontCon, topCascadeField, linkageAssign, securityGrade } = values;
      if (flag === 1) {
        if (displayFontCon) {
          if (!isShowDisplayFontCon) {
            form.setFieldsValue({
              relDisplayField: '',
              relDisplayFieldValue: '',
              displayFontConType: false,
              selfDisplayFieldValue: '',
            });
            setRelateDisplayValueList([]);
          }
        }
        setIsShowDisplayFontCon(displayFontCon);
        setIsShowDisplayFontConType(false);
      } else if (flag === 2) {
        setIsShowTopCascadeField(topCascadeField);
      } else if (flag === 3) {
        setIsShowLinkageAssign(linkageAssign);
      } else if (flag === 4) {
        if (form.getFieldValue('securityGrade') === 'encryption-level') {
          get(`/home/datamgr/v2/meta_field/encrypt_check/${fieldID}`, {}).then((res) => {
            if (res && res.message) {
              message.error(res.message, [5]);
            }
          });
        }
        form.setFieldsValue({
          encryption: null,
          desensitizationRule: null,
        });
        setIsShowEncryption(securityGrade === 'encryption-level');
        setIsDesensitizationRule(securityGrade === 'internal-level');
      }
    });
  };

const controlShowBySwitchChange = (flag) => {
    form.validateFields().then((values) => {
      const { displayFontCon, topCascadeField, linkageAssign, securityGrade, autoCode } = values;
      switch (flag) {
        case 1:
          if (displayFontCon) {
            if (!isShowDisplayFontCon) {
              form.setFieldsValue({
                relDisplayField: '',
                relDisplayFieldValue: '',
                displayFontConType: false,
                selfDisplayFieldValue: '',
              });
              setRelateDisplayValueList([]);
            }
          }
          setIsShowDisplayFontCon(displayFontCon);
          setIsShowDisplayFontConType(false);
          break;
        case 2:
          setIsShowTopCascadeField(topCascadeField);
          break;
        case 3:
          setIsShowLinkageAssign(linkageAssign);
          break;
        case 4:
          if (form.getFieldValue('securityGrade') === 'encryption-level') {
            get(`/home/datamgr/v2/meta_field/encrypt_check/${fieldID}`, {}).then((res) => {
              if (res && res.message) {
                message.error(res.message, [5]);
              }
            });
          }
          form.setFieldsValue({
            encryption: null,
            desensitizationRule: null,
          });
          setIsShowEncryption(securityGrade === 'encryption-level');
          setIsDesensitizationRule(securityGrade === 'internal-level');
          break;
        case 5:
          setIsShowAutoCode(autoCode);
          break;
        default:
          break;
      }
    });
  };

• 拒绝魔法数字 用枚举代替，没有ts就用对象代替,上面switch就很典型

export const linkageAssignTypesEnum = {
  equivalent: 1,
  splicing: 2,
  trinocular: 3,
  dateCalculate: 4,
};

export const dateCalculateRulesEnum = {
  add: 1,
  subtract: 2,
};

• import除了兄弟结构用相对路径，其他情况一律用在 webpack 中配置的别名

import Overview from '@/pages/payy/dashboard_liaocheng/overviewHospital';
import Warning from '@/pages/paxy/dashboard_dark/warning';
import GridCheck from '@/pages/paxy/dashboard_dark/gridCheck';
import Security from '@/pages/paxy/dashboard_dark/security';

• 尽量使用 es6 语法，如解构，给定默认值，let,const,箭头函数，await async
• 严格遵守eslint规范，不要随意使用disable注释去避开代码检查
• 确保单个函数单一职责代码不超过50行
• 别重复自己 消除重复代码，适当封装组件或方法
• 没必要不注释包括且限于提供信息&意图解释&阐释&警示 &TODO
• 用有意义的命名来定义逻辑判断条件

    const isShowHeadImg = field.dataFieldAttr.isShowHeadImg;
    const canShowFlag = field.dataFieldAttr.canShowFlag;
    const isHideAutoValueField = (isEdit || isAdd) && field.dataFieldAttr.canAutoValue;
    // 责任网格特殊处理
    const isGridField = field?.fieldName.split('@')[1] === 'grid_name';

React相关

• Hook代替高阶组件HOC
• 文件，文件夹名使用小驼峰
• 组件引用时使用大驼峰
• 对于 render 函数返回内容过多时(50 行)，尽量拆分组件， 表单例外。

const Left = () => {
  const { hiddenLeft } = useContext(HomeContext);
  return (
    <TweenOne animation={{ left: '-30%', duration: 800 }} reverse={!hiddenLeft}>
      <Overview />
      <Warning type={2} />
      <Security style={{ height: '23%' }} type={1} />
      <GridCheck subBlockTitleText={'医患纠纷'} />
    </TweenOne>
  );
};
