Prerequisites

Before you start coding, make sure you have the following things ready:

• Node.js on your computer:
  Node.js is a tool that lets you run JavaScript on your computer. It's important for running the web scraping script we're going to create. Download and install Node.js from the official website Node.js.

• Basic understanding of JavaScript:
  Since we're using JavaScript for web scraping, it's important to know the basics of the language. This includes understanding variables, functions, loops, and basic DOM manipulation. If you're new to JavaScript, check out introductory tutorials or documentation on websites like Mozilla Developer Network (MDN) or W3Schools.

• Crawlbase API Token:
  We'll be using Crawlbase Crawling API for efficient web scraping. The API token is needed to verify your requests. Go to the Crawlbase website, create an account, and find your API tokens in your account settings. These tokens act as keys to unlock the features of the Crawling API.

How to Scrape IMDb

Let's get your tools ready for the JavaScript code. Here's what you need to do:

1. Create Project Folder: Open your terminal and type mkdir imdb_scraper to create a new project folder.

mkdir imdb_scraper

1. Navigate to Project Folder: Type cd imdb_scraper to go into the new folder and make it easier to manage your project files.

cd imdb_scraper

1. Create JavaScript File: Type touch scraper.js to make a new file named scraper.js (you can choose a different name if you want).

touch scraper.js

1. Install Crawlbase Package: Type npm install crawlbase to add the Crawlbase tool to your project. This tool is important because it helps you communicate with the Crawlbase Crawling API, making it easier to gather information from IMDb's website.

npm install crawlbase

By following these steps, you're getting everything ready for your IMDb scraping project. You'll have a dedicated folder, a JavaScript file for your code, and the necessary Crawlbase tool for organized and efficient scraping.

Fetch the HTML Content

Now that you have your API credentials and the Node.js library for web scraping installed, let's start working on the "scraper.js" file. Pick the IMDb movie you want to scrape data from – for this example, let's focus on The Shawshank Redemption (1994). In the "scraper.js" file, use Node.js and the fs library to extract data from the chosen IMDb movie page. Remember to replace the placeholder URL in the code with the actual URL of the page you want to scrape.

const { CrawlingAPI } = require('crawlbase'),
  fs = require('fs'),
  crawlbaseToken = 'YOUR_CRAWLBASE_JS_TOKEN',
  api = new CrawlingAPI({ token: crawlbaseToken }),
  imdbPageURL = 'https://www.imdb.com/title/tt0111161/';

api.get(imdbPageURL).then(handleCrawlResponse).catch(handleCrawlError);

function handleCrawlResponse(response) {
  if (response.statusCode === 200) {
    fs.writeFileSync('response.html', response.body);
    console.log('HTML saved to response.html');
  }
}

function handleCrawlError(error) {
  console.error(error);
}

The above code snippet utilizes the Crawlbase library to scrape HTML content from the IMDb page of the movie. The script initializes a CrawlingAPI instance with a token, makes a GET request to the IMDb page, and upon a successful response with a status code of 200, it writes the HTML content to a file named "response.html". In case of any errors during the crawling process, it logs the error to the console.

Scrape IMDb Movie Data

In this section, we'll learn how to scrape important meaningful data from an IMDb movie page. The data we want to scrape includes details like the movie title, rating, release date, duration, cast, crew, story line, genre, and more. To do this, we'll build a special JavaScript scraper using two libraries: cheerio, often used for web scraping, and fs, which helps with file operations. The script we provide will analyze the HTML code of the IMDb page (which we fetched in the previous example), extract the needed information, and save it in a JSON array.

const fs = require('fs'),
  cheerio = require('cheerio');

try {
  const htmlContent = fs.readFileSync('response.html', 'utf-8'),
    $ = cheerio.load(htmlContent),
    getInnerText = (selector) => $(selector).first().text().trim(),
    getArrayFromLinks = (selector) =>
      $(selector)
        .map((_, element) => $(element).text().trim())
        .get(),
    getInnerTextBySelector = (selector) => {
      const elements = $(selector);

      if (elements.length > 0) {
        return elements
          .map((_, element) => $(element).text().trim())
          .get()
          .join(', ');
      }

      return ''; // Return an empty string if no matching elements are found
    },
    movieTitle = getInnerText('[data-testid="hero__pageTitle"] .hero__primary-text'),
    imdbRating = getInnerText('[data-testid="hero-rating-bar__aggregate-rating__score"] .sc-bde20123-1.cMEQkK'),
    genre = getInnerTextBySelector('.ipc-chip-list--baseAlt .ipc-chip__text'),
    outline = $("p[data-testid='plot'] span[class^='sc-466bb6c']").text().trim(),
    director = getInnerTextBySelector(
      'li:contains("Director") a.ipc-metadata-list-item__list-content-item--link:first',
    ),
    writers = getArrayFromLinks('li:contains("Writers") a.ipc-metadata-list-item__list-content-item--link'),
    uniqueWriters = [...new Set(writers)],
    stars = [
      ...new Set(
        $('li:contains("Stars") ul.ipc-metadata-list-item__list-content')
          .find('a.ipc-metadata-list-item__list-content-item--link')
          .map((_, element) => $(element).text().trim())
          .get(),
      ),
    ],
    userReviews = getInnerTextBySelector('a[href*="/reviews/?ref_=tt_ov_rt"] .score'),
    criticReviews = getInnerTextBySelector('a[href*="/externalreviews/?ref_=tt_ov_rt"] .score'),
    metascore = getInnerTextBySelector('a[href*="/criticreviews/?ref_=tt_ov_rt"] .score .metacritic-score-box'),
    releaseDate = getInnerTextBySelector(
      '[data-testid="title-details-releasedate"] .ipc-metadata-list-item__list-content-item--link',
    ),
    countryOfOrigin = getInnerTextBySelector(
      '[data-testid="title-details-origin"] .ipc-metadata-list-item__list-content-item--link',
    ),
    language = getInnerTextBySelector(
      '[data-testid="title-details-languages"] .ipc-metadata-list-item__list-content-item--link',
    ),
    productionCompany = getInnerTextBySelector(
      '[data-testid="title-details-companies"] .ipc-metadata-list-item__list-content-item--link',
    );

  const movieData = {
    movieTitle,
    imdbRating,
    genre,
    director,
    writers: uniqueWriters,
    stars,
    userReviews,
    criticReviews,
    metascore,
    releaseDate,
    countryOfOrigin,
    language,
    productionCompany,
    outline,
  };

  console.log(JSON.stringify(movieData, null, 2));
} catch (error) {
  console.error('Error reading or parsing the HTML file:', error);
}

The provided JavaScript code uses the cheerio library to parse and extract information from an HTML file of IMDb page. The script reads the HTML content from the "response.html" file, loads it into a Cheerio instance, and then employs various selectors and extraction functions to gather data.

The extracted movie data includes the title, IMDb rating, genre, plot outline, director, writers, stars, user reviews, critic reviews, metascore, release date, country of origin, language, and production company. The information is organized into a movieData object and printed as a formatted JSON string

JSON Response:

  "movieTitle": "The Shawshank Redemption",
  "imdbRating": "9.3",
  "genre": "Drama",
  "director": "Frank Darabont",
