These two lines could be found at the bottom of the file: You could access the file by adding "/robots.txt" by the end of the link to your target website.Įnter in your browser, and let’s check the robots file of Facebook. Robots.txt is a file used by websites to let "bots" know if or how the site should be scrapped or crawled and indexed. When planning to scrape a website, you should always check its robots.txt first.
$('div > div').1. Actually, Facebook disallows any scraper, according to its robots.txt file. * Get extra properties from the profile */ Let profilePictureUrl = $('img').attr('href') * Send the request to the user page and get the results */ We need to simulate a request to the dev.to website just like a normal browser would and get the HTML content of it.Ĭonst request = require('request-promise') The first phase is pretty straight forward. Let's get right at it, I don't like to waste time talking non sense without actually showing some code and results.
I also post a lot content like this on my Scraping Blog including a nice article on Scraping Instagram Profile Data with NodeJs 💻 I very much want to mention that if you still Web Scrape with callbacks or chained promises, this is going to be a nice refresh to you because we are going to use async await syntax. We're gonna scrape basic details of any dev.to member page. You can easily initiate one on a new empty folder with npm.Īnd after completing these steps you must install the libraries that we're gonna use by running the following lines ( while on the same new project ):įor this example I am going to take this community website dev.to because I want to make this unique and directly dedicated to all you people 😋 Now, we need to make sure that you have a new project ready to write the code. I will assume that you already have Node.Js installed on your laptop or pc and if not, what are you waiting for? 🔥 Request-Promise - In order to make the requests and to get the contents of the website you want to scrape.Ĭheerio - Probably the most used library to parse html content with NodeJs with a Jquery-like syntax Request - Peer dependency for request-promise Here are the tools that I am going to use for this example, these are the perfect tools for getting started This is the case that you go and start with Web Scraping. You want to get information of a instagram profile, followers, followings, uploads, description and other informations which may not be available to an API or you may not have access to that API.
I'm not going to make it boring for you with scientific technical explanation so, Today we're gonna get started with Web Scraping with NodeJs with some cool and simple examples
