    if (newHeight === lastHeight) {
      break;
    }

  }
}

async function fillInfoFromPage(page) {
  return await page.evaluate(async () => {
    return Array.from(document.querySelectorAll(".iFjolb")).map((el) => ({
      title: el.querySelector(".BjJfJf").textContent.trim(),
      companyName: el.querySelector(".vNEEBe").textContent.trim(),
      location: el.querySelectorAll(".Qk80Jf")[0].textContent.trim(),
      via: el.querySelectorAll(".Qk80Jf")[1].textContent.trim(),
      thumbnail: el.querySelector(".pJ3Uqf img")?.getAttribute("src"),
      extensions: Array.from(el.querySelectorAll(".oNwCmf .I2Cbhb .LL4CDc")).map((el) => el.textContent.trim()),

  });
}

  const browser = await puppeteer.launch({
    headless: false,
    args: ["--no-sandbox", "--disable-setuid-sandbox"],
  });

  const page = await browser.newPage();

  const URL = `${domain}/search?ibp=htl;jobs&hl=${requestParams.hl}&q=${requestParams.q}&uule=${requestParams.uule}`;

  await page.setDefaultNavigationTimeout(60000);
  await page.goto(URL);
  await page.waitForSelector(".iFjolb");
  await page.waitForTimeout(1000);

  await scrollPage(page, ".zxU94d");

  const jobs = await fillInfoFromPage(page);

  await browser.close();

  return jobs;
}

getJobsInfo().then((result) => console.dir(result, { depth: null }));

Preparation

First, we need to create a Node.js* project and add npm packages puppeteer, puppeteer-extra and puppeteer-extra-plugin-stealth to control Chromium (or Chrome, or Firefox, but now we work only with Chromium which is used by default) over the DevTools Protocol in headless or non-headless mode.

To do this, in the directory with our project, open the command line and enter npm init -y, and then npm i puppeteer puppeteer-extra puppeteer-extra-plugin-stealth.

*If you don't have Node.js installed, you can download it from nodejs.org and follow the installation documentation.

📌Note: also, you can use puppeteer without any extensions, but I strongly recommended use it with puppeteer-extra with puppeteer-extra-plugin-stealth to prevent website detection that you are using headless Chromium or that you are using web driver. You can check it on Chrome headless tests website. The screenshot below shows you a difference.

Process

First of all, we need to scroll through all job listings until there are no more listings loading which is the difficult part described below.

The next step is to extract data from HTML elements after scrolling is finished. The process of getting the right CSS selectors is fairly easy via SelectorGadget Chrome extension which able us to grab CSS selectors by clicking on the desired element in the browser. However, it is not always working perfectly, especially when the website is heavily used by JavaScript.

We have a dedicated web Scraping with CSS Selectors blog post at SerpApi if you want to know a little bit more about them.

The Gif below illustrates the approach of selecting different parts of the results.

Code explanation

Declare puppeteer to control Chromium browser from puppeteer-extra library and StealthPlugin to prevent website detection that you are using web driver from puppeteer-extra-plugin-stealth library:

const puppeteer = require("puppeteer-extra");
const StealthPlugin = require("puppeteer-extra-plugin-stealth");

Next, we "say" to puppeteer use StealthPlugin, write what we want to search and encode it into URI string:

puppeteer.use(StealthPlugin());

const searchString = "javascript developer"; // what we want to search
const encodedString = encodeURI(searchString); // what we want to search for in URI encoding

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

📌Note: the uule parameter is an encoded location parameter. You can make it using UULE Generator for Google.

const requestParams = {
  q: encodedString, // our encoded search string
  hl: "en", // parameter defines the language to use for the Google search
  uule: "w+CAIQICIKY2FsaWZvcm5pYQ", // encoded location
};

const domain = `https://www.google.com`;

Next, we write a function to scroll the page to load all the articles:

async function scrollPage(page, scrollContainer) {
  ...
}

In this function, first, we need to get scrollContainer height (using evaluate() method). Then we use while loop in which we scroll down scrollContainer, wait 2 seconds (using waitForTimeout method), and get a new scrollContainer height.

Next, we check if newHeight is equal to lastHeight we stop the loop. Otherwise, we define newHeight value to lastHeight variable and repeat again until the page was not scrolled down to the end:

let lastHeight = await page.evaluate(`document.querySelector("${scrollContainer}").scrollHeight`);
while (true) {
  await page.evaluate(`document.querySelector("${scrollContainer}").scrollTo(0, document.querySelector("${scrollContainer}").scrollHeight)`);
  await page.waitForTimeout(2000);
  let newHeight = await page.evaluate(`document.querySelector("${scrollContainer}").scrollHeight`);
  if (newHeight === lastHeight) {
    break;
  }
  lastHeight = newHeight;
}

Next, we write a function to get jobs data from the page:

async function fillInfoFromPage(page) {
  ...
}

In this function, we get information from the page context and save it in the returned array. First, we need to get all the jobs results available on the page (querySelectorAll() method) and make the new array from got NodeList (Array.from()):

return await page.evaluate(async () => {
    return Array.from(document.querySelectorAll(".iFjolb")).map((el) => ({

Next, we assign the necessary data to each object's key. We can do this with textContent and trim() methods, which get the raw text and removes white space from both sides of the string. If we need to get links, we use getAttribute() method to get "src" HTML element attributes:

  title: el.querySelector(".BjJfJf").textContent.trim(),
  companyName: el.querySelector(".vNEEBe").textContent.trim(),
  location: el.querySelectorAll(".Qk80Jf")[0].textContent.trim(),
  via: el.querySelectorAll(".Qk80Jf")[1].textContent.trim(),
  thumbnail: el.querySelector(".pJ3Uqf img")?.getAttribute("src"),
  extensions: Array.from(el.querySelectorAll(".oNwCmf .I2Cbhb .LL4CDc")).map((el) => el.textContent.trim()),

Next, write a function to control the browser, and get information:

async function getJobsInfo() {
  ...
}

In this function first we need to define browser using puppeteer.launch({options}) method with current options, such as headless: false and args: ["--no-sandbox", "--disable-setuid-sandbox"].

These options mean that we use headless mode and array with arguments which we use to allow the launch of the browser process in the online IDE. And then we open a new page:

const browser = await puppeteer.launch({
  headless: false,
  args: ["--no-sandbox", "--disable-setuid-sandbox"],
});

const page = await browser.newPage();

Next, we define the full request URL, change default (30 sec) time for waiting for selectors to 60000 ms (1 min) for slow internet connection with .setDefaultNavigationTimeout() method, go to URL with .goto() method and use .waitForSelector() method to wait until the selector is load:

const URL = `${domain}/search?ibp=htl;jobs&hl=${requestParams.hl}&q=${requestParams.q}&uule=${requestParams.uule}`;

await page.setDefaultNavigationTimeout(60000);
await page.goto(URL);
await page.waitForSelector(".iFjolb");

And finally, we wait until the page was scrolled, save jobs data from the page in the jobs constant, close the browser, and return the received data:

await scrollPage(page, ".zxU94d");

const jobs = await fillInfoFromPage(page);

await browser.close();

return jobs;

Now we can launch our parser:

$ node YOUR_FILE_NAME # YOUR_FILE_NAME is the name of your .js file

Output

[
   {
      "title":"Python Developer Python-JavaScript and vue.js",
      "companyName":"Dice",
      "location":"San Francisco, CA",
      "via":"via LinkedIn",

         "Contractor"
      ]
   },
   {

      "companyName":"Jobot",
      "location":"Las Vegas, NV",
      "via":"via Central Illinois Proud Jobs",
      "extensions":[

         "Full-time",

      ]
   },
   ... and other results
]

Using Google Jobs API from SerpApi

This section is to show the comparison between the DIY solution and our solution.

The biggest difference is that you don't need to use browser automation to scrape results, create the parser from scratch and maintain it.

There's also a chance that the request might be blocked at some point from Google, we handle it on our backend so there's no need to figure out how to do it yourself or figure out which CAPTCHA, proxy provider to use.

First, we need to install google-search-results-nodejs:

npm i google-search-results-nodejs

Here's the full code example, if you don't need an explanation:

const SerpApi = require("google-search-results-nodejs");
const search = new SerpApi.GoogleSearch(process.env.API_KEY);

const searchString = "javascript developer"; // what we want to search

const params = {
  engine: "google_jobs", // search engine
  q: searchString, // search query
  hl: "en", // Parameter defines the language to use for the Google search
  uule: "w+CAIQICIKY2FsaWZvcm5pYQ", // encoded location
};

const getJson = () => {
  return new Promise((resolve) => {
    search.json(params, resolve);
  });
};

const getResults = async () => {
  const organicResults = [];
  while (true) {
    const json = await getJson();
    if (json.search_information?.jobs_results_state === "Fully empty") break;
    organicResults.push(...json.jobs_results);
    params.start ? (params.start += 10) : (params.start = 10);
  }
  return organicResults;
};

getResults().then((result) => console.dir(result, { depth: null }));

Code explanation

First, we need to declare SerpApi from google-search-results-nodejs library and define new search instance with your API key from SerpApi:

const SerpApi = require("google-search-results-nodejs");
const search = new SerpApi.GoogleSearch(API_KEY);

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

📌Note: the uule parameter is an encoded location parameter. You can make it using UULE Generator for Google.

const searchString = "javascript developer"; // what we want to search

const params = {
  engine: "google_jobs", // search engine
  q: searchString, // search query
  hl: "en", // Parameter defines the language to use for the Google search
  uule: "w+CAIQICIKY2FsaWZvcm5pYQ", // encoded location
};

Next, we wrap the search method from the SerpApi library in a promise to further work with the search results:

const getJson = () => {
  return new Promise((resolve) => {
    search.json(params, resolve);
  });
};

And finally, we declare the function getResult that gets data from the page and return it:

const getResults = async () => {
  ...
};

In this function first, we declare an array organicResults with results data:

const organicResults = [];

Next, we need to use while loop. In this loop we get json with results, check if results are present on the page (jobs_results_state isn't "Fully empty"), push results to organicResults array, define the start number on the results page, and repeat the loop until results aren't present on the page:

while (true) {
  const json = await getJson();
  if (json.search_information?.jobs_results_state === "Fully empty") break;
  organicResults.push(...json.jobs_results);
  params.start ? (params.start += 10) : (params.start = 10);
}
return organicResults;

After, we run the getResults function and print all the received information in the console with the console.dir method, which allows you to use an object with the necessary parameters to change default output options:

getResults().then((result) => console.dir(result, { depth: null }));
