How To Perform Web Scraping Of Google Jobs Organic Results With Nodejs?

Basic Steps Included in Web Scraping

• Create a request to the web page for scraping data.
• Extract the web page body.
• Understand the tags or elements structure to extract from the webpage and make changes in the code to link accordingly.

Why use Node.js?

Node.js, an open-source project, is a popular runtime environment with collective features for easy-to-develop stuff. Within a web browser, manipulating the DOM is something that JavaScript & libraries like jQuery perform well. Hence, writing web scraping scripts in Node.js is better, as it gives enough options for DOM manipulations.

Web scraping of Google Jobs Organic Results with Nodejs

Here, we will brief you on the web scraping of Google Jobs with Nodejs.

First of all, we will install google-search-results-nodejs

The complete code will look like this.

npm i google-search-results-node.js

The complete code will look like this.

Explanation of Code

Here, we will brief you on the web scraping of Google Jobs with Nodejs.

We will first declare SerpApi from google-search-results-nodejs the library and then define a new search instance using the API key from SerpApi:

Next, we will write a search query and the required parameters for making a request:

Then, we cover the search method from the SerpApi library

Finally, we declare the getResult function to get and return data from the page.

In this function, first, we declare a list of organicResults with the result data.

Now, we will use a while loop. In this loop, we obtain json with results. Track if the results are available on the page jobs results state isn’t “Fully empty” move the results to the organicResult list, mention the start number on the results page, and repeat the same until you get the results on the page.

After running the getResults function and printing all the necessary information in the console, using a console.dr process, it allows using an object with the necessary parameters.

Output

The output will be like this:

Preparation

First, create the Node.js project and then add npm packages, including a puppeteer, puppeteer-extra, and puppeteer-extra-plugin-stealth for controlling Chrome or Firefox.

To perform this, open the command line and enter npm init -y , and then npm i puppeteer puppeteer-extra puppeteer-extra-plugin-stealth

Process

Using the SelectorGadget Chrome extension, getting the correct CSS selector is very easy. First, we will scroll through all job listings until no more are available. Then, after finishing scrolling, we will extract data from HTML. The below Gif presents the approach of selecting different parts of the results.

Explanation of the Code

Instruct the puppeteer to control the Chrome browser using puppeteer-extra and StealthPlugin to restrict the website from detecting that you are using a web driver from detecting that you are using a web driver from puppeteer-extra-plugin-stealth library

Now, add ‘use’ to puppeteer stealthPlugin. Mention what we are searching for and encode it within the URI string.

Next, we will write the request parameters and Google domain URL:

We will then write a function to scroll the page to load all articles.

In this function, first, we require ScrollContainer height. Then, we will use a while loop to scroll down, wait for 2 seconds, and get a new ScrollContainer height.

Next, we will stop the loop if the newHeight is equivalent to lastHeight. Otherwise, we will define the newHeight value to the lastHeight variable and repeat the same until the pages don’t scroll completely.

Next, we will write a function to get the job data from the page

First, we will get all the job results on querySelectorAll() and make a new list from got NodeList.

The next step is to assign the essential data to each object’s key using textContent and trim() methods. It gets the raw text and eliminates white space from both ends of the string.

To control the browse and avail information, we will write a function.

In this function, first, we will define a browser using puppeteer.launch method with current options. It includes headless: false and args: [“–no-sandbox”, “–disable-setuid-sendbox”]

>

We will open a new page:

Next, we define the complete request URL, change the default time for waiting, and obtain the following:

Finally, we will wait for the page to scroll, save jobs data, close the browser, and return the received data:

We will now launch the parser:

Output

The output result will appear like this:

Conclusion: Finally, we have done web scraping of the Google jobs organic results with Nodejs. It will give complete detail on the type of jobs, company name, location of the company, etc.
