crawler.ts

import axios from 'axios'
import { JSDOM } from 'jsdom'

export const crawling = async (url: string) => {
    try {
        const response = await axios.get(url)
        const { window } = new JSDOM(response.data)

        // * 크롤링 코드 시작
        const iframePath = window.document.querySelector('#contentarea_left > iframe').src
        if (!iframePath) throw new Error()

        const timeAndIsOpenedData = window.document.querySelector('#time').textContent.trim().split(' ')
        if (!timeAndIsOpenedData) throw new Error()

        const currentDate = timeAndIsOpenedData[0].split('.').join('-')
        const isOpen = timeAndIsOpenedData[1] != '닫힘'
        // * 크롤링 코드 완료

        return {
            innerURL: `${url}/${iframePath}`,
            currentDate,
            isOpen,
        }
