Next, let’s open a new text file (name the file potusScraper.js), and write a quick function to get the HTML of the Wikipedia “List of Presidents” page.Ĭool, we got the raw HTML from the web page! But now we need to make sense of this giant blob of text.

presidents from Wikipedia and the titles of all the posts on the front page of Reddit.įirst things first: Let’s install the libraries we’ll be using in this guide (Puppeteer will take a while to install as it needs to download Chromium as well). We will be gathering a list of all the names and birthdays of U.S.

Working through the examples in this guide, you will learn all the tips and tricks you need to become a pro at gathering any data you need with Node.js! This guide will walk you through the process with the popular Node.js request-promise module, CheerioJS, and Puppeteer.

and parsing the data to get the exact information you want.

acquiring the data using an HTML request library or a headless browser,.

Getting started with web scraping is easy, and the process can be broken down into two main parts: Or you could even be wanting to build a search engine like Google! Maybe you want to collect emails from various directories for sales leads, or use data from the internet to train machine learning/AI models. Or perhaps you need flight times and hotel/AirBNB listings for a travel site. There are a lot of use cases for web scraping: you might want to collect prices from various e-commerce sites for a price comparison site. After that, names and values are passed directly to the browser object.So what’s web scraping anyway? It involves automating away the laborious task of collecting information from websites. Then, we navigated to the login URL and selected the form. Then a Mechanize browser object has been created.

The above code is very easy to understand.

In this example, we are going to automate the process of filling a login form having two fields namely email and password − Note that it would work only in Python 2.x. Before starting using it we need to install it with the following command − Mechanize module provides us a high-level interface to interact with forms. In this section we are going to deal with a Python module named Mechanize that will reduce our work and automate the process of filling up forms. Observe that you can easily understand the difference between script with session and without session. In the above line of code, the URL would be the page which will act as the processor for the login form. R = session.post(“enter the URL”, data = parameters) Now, we need to provide the information for the fields of login form. In this section, we are going to deal with a simple submit form with the help of Python requests library.įirst, we need to import requests library as follows − They may be very simple like including only a very few HTML fields, a submit button and an action page or they may be complicated and have some additional fields like email, leave a message along with captcha for security reasons. While working on Internet, you must have interacted with login forms many times. These days In previous chapters, we worked with HTTP GET method to request information but in this chapter we will work with HTTP POST method that pushes information to a web server for storage and analysis. In this chapter, let us understand scraping of websites that work on user based inputs, that is form based websites. In the previous chapter, we have seen scraping dynamic websites.
