使用 sort-imports 排序规则美化头部 import 代码

我们在开发一个页面的时候，文件头部总是会有一堆 import 代码，特别是使用 React 技术栈的同学感同身受，随着项目代码的增多，如果不对头部的代码进行分层，会导致代码看起来很冗余，我们需要它按照一定的规则进行排序。

问题本质

当头部 import 代码过多时，它往往是这样的：

import { useAntdTable, useBoolean, useRequest, useSetState } from 'ahooks'
import type { ColumnsType, ColumnType } from 'antd/es/table';
import ImportFileModal from './components/ImportFileModal'
import ImportFundReceiptListTable from './components/ImportFundReceiptListTable'
import { get, reduce, toNumber } from 'lodash'
import moment, { Moment } from 'moment'
import React, { FC, useState } from 'react'
import { Link } from 'react-router-dom';
import PageHeaderWrapper from '@/components/PageHeaderWrapper';
import { transPostToGet } from '@/utils/utils';
import ImportErrorModal from './components/ImportErrorModal'
import ImportNumberModal from './components/ImportNumberModal'
import TrendTotal from './components/TrendTotal'
import { Button, Card, Col, DatePicker, Form, Row, Space, Table } from 'antd'
import { FundReceiptTable, Json2DBParams, TableParams } from './utils/interface'
import { generatePageJson, getReceiptList, saveJsonDB } from './utils/service'

如果不进行处理，可读性极差，对于有强迫症的我实在忍不了。

配置 Eslint

Eslint 官网本身提供了一条名叫 sort-imports 的规则，首先我们需要安装一个插件 eslint-plugin-simple-import-sort：
1
pnpm add -D eslint-plugin-simple-import-sort

配置 .eslintrc.cjs 文件，加入配置：

{
  "plugins": ["simple-import-sort"],
  "rules": {
    "simple-import-sort/imports": "error",
  }
}

这样我们就配置好了，以后当我们开发页面的时候，Eslint 会自动帮我们把头部的 import 代码进行排序。

排序后是这样的：

import { useAntdTable, useBoolean, useRequest, useSetState } from 'ahooks'
import { Button, Card, Col, DatePicker, Form, Row, Space, Table } from 'antd'
import type { ColumnsType, ColumnType } from 'antd/es/table';
import { get, reduce, toNumber } from 'lodash'
import moment, { Moment } from 'moment'
import React, { FC, useState } from 'react'
import { Link } from 'react-router-dom';

import PageHeaderWrapper from '@/components/PageHeaderWrapper';
import { transPostToGet } from '@/utils/utils';

import ImportErrorModal from './components/ImportErrorModal'
import ImportFileModal from './components/ImportFileModal'
import ImportFundReceiptListTable from './components/ImportFundReceiptListTable'
import ImportNumberModal from './components/ImportNumberModal'
import TrendTotal from './components/TrendTotal'
import { FundReceiptTable, Json2DBParams, TableParams } from './utils/interface'
import { generatePageJson, getReceiptList, saveJsonDB } from './utils/service'
