Parse the HTML let $ = cheerio.load( "Hello world") It provides a jQuery-like interface to interact with a piece of HTML you already have. Once we have a piece of HTML, we need to parse it. Tinyreq is actually a friendlier wrapper around the native http.request built-in solution. Using this module, you can easily get the HTML rendered by the server from a web page: const request = require( "tinyreq") Ĭonsole.log(err || body) // Print out the HTML Like always, I recommend choosing simple/small modules - I wrote a tiny package that does it: tinyreq. There are a lot of modules doing that that. To load the web page, we need to use a library that makes HTTP(s) requests. It's designed to be really simple to use and still is quite minimalist. In Node.js, all these three steps are quite easy because the functionality is already made for us in different modules, by different developers.īecause I often scrape random websites, I created yet another scraper: scrape-it – a Node.js scraper for humans. We load the page (a GET request is often enough).When there is no web based API to share the data with our app, and we still want to extract some data from that website, we have to fallback to scraping. A smart script can do the job pretty good, especially if it's something repetitive. Obviously, a human is not needed for that. Sometimes we need to collect information from different web pages automagically.
