海外TECH	DEV Community	Web Scraping in Node.js!	https://dev.to/code_jedi/web-scraping-in-nodejs-2lkf	Web Scraping in Node js Web scraping Web Scraping is a way to collect all sorts of publicly available data like prices text images contact information and much more from the world wide web This can be useful when trying to collect data that might take a person a lot of time to collect and organize manually Some of the most useful use cases of web scraping include Scraping product prices from e commerce websites such as amazon ebay or alibaba Scraping social media posts likes comments followers or bios Scraping contacts from websites like yellowpages or Linkedin PuppeteerWhile there are a few different libraries for scraping the web with Node js in this tutorial i ll be using the puppeteer library Puppeteer is a popular and easy to use npm package used for web automation and web scraping purposes Some of puppeteer s most useful features include Being able to extract a scraped element s text content Being able to interact with a webpage by filling out forms clicking on buttons or running searches inside a search bar Being able to scrape and download images from the web Being able to see the web scraping in progress using headless mode You can read more about puppeteer here InstallationFor this tutorial I will suppose you already have npm and node modules installed as well as a package json and package lock json file If you don t here s a great guide on how to do so SetupTo install puppeteer run one of the following commands in your project s terminal npm i puppeteerOryarn add puppeteerOnce puppeteer is installed it will appear as a directory inside your node modules Let s make a simple web scraping script in Node jsThe web scraping script will get the first synonym of smart from the web thesaurus by Getting the HTML contents of the web thesaurus webpage Finding the element that we want to scrape through it s selector Displaying the text contents of the scraped element Let s get started Before scraping and then extracting this element s text through it s selector in Node js we need to setup a few things first Create or open an empty javascript file you can name it whatever you want but I ll name mine index js for this tutorial Then require puppeteer on the first line and create the async function inside which we will be writing our web scraping code index jsconst puppeteer require puppeteer async function scrape scrape Next initiate a new browser instance and define the page variable which is going to be used for navigating to webpages and scraping elements within a webpage s HTML contents index jsconst puppeteer require puppeteer async function scrape const browser await puppeteer launch const page await browser newPage scrape Scraping the first synonym of smart To locate and copy the selector of the first synonym of smart which is what we re going to use to locate the synonym inside of the web thesaurus webpage first go to the web thesaurus synonyms of smart right click on the first synonym and click on inspect This will make this webpage s DOM pop up at the right of your screen Next right click on the highlighted HTML element containing the first synonym and click on copy selector Finally to navigate to the web thesaurus scrape and display the first synonym of smart through the selector we copied earlier First make the page variable navigate to inside the newly created browser instance Next we define the element variable by making the page wait for our desired element s selector to appear in the webpage s DOM The text content of the element is then extracted using the evaluate function and displayed inside the text variable Finally we close the browser instance index jsconst puppeteer require puppeteer async function scrape const browser await puppeteer launch const page await browser newPage await page goto var element await page waitFor meanings gt div css ixatld erdun gt ul gt li nth child gt a var text await page evaluate element gt element textContent element console log text browser close scrape Time to testNow if you run your index js script using node index js you will see that it has displayed the first synonym of the word smart Scraping the top synonyms of smartWe can implement the same code to scrape the top synonyms of smart instead of index jsconst puppeteer require puppeteer async function scrape const browser await puppeteer launch const page await browser newPage await page goto for i i lt i var element await page waitFor meanings gt div css ixatld erdun gt ul gt li nth child i gt a var text await page evaluate element gt element textContent element console log text browser close scrape The element variable will be meanings gt div css ixatld erdun gt ul gt li nth child gt a on the first iteration meanings gt div css ixatld erdun gt ul gt li nth child gt a on the second and so on until it reaches the last iteration where the element variable will be meanings gt div css ixatld erdun gt ul gt li nth child gt a As you can see the only thing that is altered in the element variable throughout the iterations is the li nth child value This is because in our case the elements that we are trying to scrape are all li elements inside a ul element so we can easily scrape them in order by increasing the value inside li nth child li nth child for the first synonym li nth child for the second synonym li nth child for the third synonym li nth child for the fourth synonym And li nth child for the fifth synonym Final notesWhile web scraping has many advantages like Saving time on manually collecting data Being able to programmatically aggregate pieces of data scraped from the web Creating a dataset of data that might be useful for machine learning data visualization or data analytics purposes It also has disadvantages Some websites don t allow for scraping their data one popular example is craigslist Some people consider it to be a gray area since some use cases of web scraping practice user or entity data collection and storage Wrapping upHopefully this article gave you some insight into web scraping in Node js it s practical applications pros and cons and how to extract specific elements and their text contents from webpages using the puppeteer library	2021-10-13 16:49:39
