Node.js로 인프런 강의 크롤링하기

생각보다 코드가 심플해서 신기하다 .

 

 

 

 

 

const axios = require("axios");

const cheerio = require("cheerio");

const getHTML = async (keyword) => {

  try {

    return await axios.get(

      "https://www.inflearn.com/courses?s=" + encodeURI(keyword)

    );

  } catch (err) {

    console.log(err);

  }

};

// 파싱

const parsing = async (keyword) => {

  const html = await getHTML(keyword);

  const $ = cheerio.load(html.data);

  const $courseList = $(".course_card_item");

  let courses = [];

  $courseList.each((idx, node) => {

    const title = $(node).find(".course_title").text();

    courses.push({

      title: $(node).find(".course_title").text(),

      instructor: $(node).find(".instructor").text(),

      price: $(node).find(".price").text(),

      rating: $(node).find(".star_solid").css("width"),

      image: $(node).find(".card-img > figure > img").attr("src"),

    });

  });

  console.log(courses);

};

parsing("자바스크립트");
