What will be scraped
Preparation
First, we need to create a Node.js project and add npm
packages cheerio
to parse parts of the HTML markup, and axios
to make a request to a website. To do this, in the directory with our project, open the command line and enter npm init -y
, and then npm i cheerio axios
.
Process
SelectorGadget Chrome extension was used to grab CSS selectors by clicking on the desired element in the browser. If you have any struggles understanding this, we have a dedicated Web Scraping with CSS Selectors blog post at SerpApi.
The Gif below illustrates the approach of selecting different parts of the results.
Full code
const cheerio = require("cheerio");
const axios = require("axios");
const searchString = "elon musk"; // what we want to search
const encodedString = encodeURI(searchString); // what we want to search for in URI encoding
const AXIOS_OPTIONS = {
headers: {
"User-Agent":
"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36",
}, // adding the User-Agent header as one way to prevent the request from being blocked
params: {
q: encodedString, // our encoded search string
tbm: "nws", // parameter defines the type of search you want to do ("nws" means news)
hl: 'en', // Parameter defines the language to use for the Google search
gl: 'us' // parameter defines the country to use for the Google search
},
};
function getNewsInfo() {
return axios
.get(`http://google.com/search`, AXIOS_OPTIONS)
.then(function ({ data }) {
let $ = cheerio.load(data);
const pattern = /s='(?<img>[^']+)';\w+\s\w+=\['(?<id>\w+_\d+)'];/gm;
const images = [...data.matchAll(pattern)].map(({ groups }) => ({ id: groups.id, img: groups.img.replace('\\x3d', '') }))
const allNewsInfo = Array.from($('.WlydOe')).map((el) => {
return {
link: $(el).attr('href'),
source: $(el).find('.CEMjEf span').text().trim(),
title: $(el).find('.mCBkyc').text().trim().replace('\n', ''),
snippet: $(el).find('.GI74Re').text().trim().replace('\n', ''),
image: images.find(({ id, img }) => id === $(el).find('.uhHOwf img').attr('id'))?.img || "No image",
date: $(el).find('.ZE0LJd span').text().trim(),
}
});
return allNewsInfo;
});
}
getNewsInfo().then(console.log);
Code explanation
Declare constants from required libraries:
const cheerio = require("cheerio");
const axios = require("axios");
Code | Explanation |
---|---|
cheerio |
library for parsing the html page and access the necessary selectors |
axios |
library for requesting the desired html document |
Next, we write in constants what we want to search for and encode our text into a URI string:
const searchString = "elon musk";
const encodedString = encodeURI(searchString);
Code | Explanation |
---|---|
searchString |
what we want to search |
encodedString |
what we want to search for in URI encoding |
Next, we write down the necessary parameters for making a request:
const AXIOS_OPTIONS = {
headers: {
"User-Agent":
"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36",
},
params: {
q: encodedString,
tbm: "nws",
hl: 'en',
gl: 'us'
},
};
Code | Explanation |
---|---|
headers |
HTTP headers let the client and the server pass additional information with an HTTP request or response |
User-Agent |
is used to act as a "real" user visit. Default axios requests user-agent is axios/0.27.2 so websites understand that it's a script that sends a request and might block it. Check what's your user-agent. |
q |
encoded in URI search query |
tbm |
parameter defines the type of search you want to do ("nws" means news) |
hl |
parameter defines the language to use for the Google search |
gl |
parameter defines the country to use for the Google search |
And finally a function to get the necessary information:
function getNewsInfo() {
return axios
.get(`http://google.com/search`, AXIOS_OPTIONS)
.then(function ({ data }) {
let $ = cheerio.load(data);
const pattern = /s='(?<img>[^']+)';\w+\s\w+=\['(?<id>\w+_\d+)'];/gm;
const images = [...data.matchAll(pattern)].map(({ groups }) => ({ id: groups.id, img: groups.img.replace('\\x3d', '') }))
const allNewsInfo = Array.from($('.WlydOe')).map((el) => {
return {
link: $(el).attr('href'),
source: $(el).find('.CEMjEf span').text().trim(),
title: $(el).find('.mCBkyc').text().trim().replace('\n', ''),
snippet: $(el).find('.GI74Re').text().trim().replace('\n', ''),
image: images.find(({ id, img }) => id === $(el).find('.uhHOwf img').attr('id'))?.img || "No image",
date: $(el).find('.ZE0LJd span').text().trim(),
}
});
return allNewsInfo;
});
}
Code | Explanation |
---|---|
function ({ data }) |
we received the response from axios request that have data key that we destructured (this entry is equal to function (response) and in the next line cheerio.load(response.data) ) |
pattern |
a RegEx pattern for search and define full images. See what it allows you to find |
images |
an array that contains the id of the img selector and the image itself |
[...data.matchAll(pattern)] |
in this code we use spread syntax to create an array from an iterator that was returned from matchAll method (in this case this entry is equal to Array.from(data.matchAll(pattern)) ) |
.replace('\\x3d', '') |
in this code we remove \\x3d chars from the end of the base64 image format string to display image properly |
allNewsInfo |
an array with full info about news from page |
.attr('href') |
gets the href attribute value of the html element |
$(el).find('.mCBkyc') |
finds element with class name mCBkyc in all child elements and their children of el html element |
.text() |
gets the raw text of html element |
.trim() |
removes whitespace from both ends of a string |
Now we can launch our parser. To do this enter node YOUR_FILE_NAME
in your command line. Where YOUR_FILE_NAME
is the name of your .js
file.

Google News Result API
Alternatively, you can use the Google News Result API from SerpApi. SerpApi is a free API with 100 search per month. If you need more searches, there are paid plans.
The difference is that all that needs to be done is just to iterate over a ready made, structured JSON instead of coding everything from scratch maintaining, figuring out how to bypass blocks from Google, and selecting correct selectors which could be time consuming at times. Check out the playground.
First we need to install google-search-results-nodejs
. To do this you need to enter in your console: npm i google-search-results-nodejs
const SerpApi = require("google-search-results-nodejs");
const search = new SerpApi.GoogleSearch(API_KEY); //your API key from serpapi.com
const searchString = "elon musk"; // what we want to search
const params = {
engine: "google", // search engine
q: searchString, // search query
google_domain: "google.com", // google domain: google.com, google.de, google.fr
gl: "us", // parameter defines the country to use for the Google search
hl: "en", // Parameter defines the language to use for the Google search
tbm: "nws" // parameter defines the type of search you want to do ("nws" means news)
};
const getNewsData = function ({ news_results }) {
return news_results.map((result) => {
const { link, title, source, date, snippet, thumbnail: image = "No image" } = result;
return {
link,
source,
title: title.replace('\n', ''),
snippet: snippet.replace('\n', ''),
image,
date,
}
})
};
const getJson = (params) => {
return new Promise((resolve) => {
search.json(params, resolve);
})
}
getJson(params).then(getNewsData).then(console.log)
Code explanation
Declare constants from required libraries:
const SerpApi = require("google-search-results-nodejs");
const search = new SerpApi.GoogleSearch(API_KEY);
Code | Explanation |
---|---|
SerpApi |
SerpApi Node.js library |
search |
new instance of GoogleSearch class |
API_KEY |
your API key from SerpApi |
Next, we write down what we want to search and the necessary parameters for making a request:
const searchString = "elon musk";
const params = {
engine: "google",
q: searchString,
google_domain: "google.com",
gl: "us",
hl: "en",
tbm: "nws"
Code | Explanation |
---|---|
searchString |
what we want to search |
engine |
search engine |
q |
search query |
google_domain |
google domain: google.com, google.de, google.fr |
gl |
parameter defines the country to use for the Google search |
hl |
parameter defines the language to use for the Google search |
tbm |
parameter defines the type of search you want to do ("nws" means news) |
Next, we write a callback function in which we describe what data we need from the result of our request:
const getNewsData = function ({ news_results }) {
return news_results.map((result) => {
const { link, title, source, date, snippet, thumbnail: image = "No image" } = result;
return {
link,
source,
title: title.replace('\n', ''),
snippet: snippet.replace('\n', ''),
image,
date,
}
})
};
Code | Explanation |
---|---|
news_results |
an array that we destructured from response |
link, title, source, date, snippet, thumbnail |
other data that we destructured from element of news_results array |
thumbnail: image = "No image" |
we redefine destructured data thumbnail to new image and set default value No image if thumbnail is undefined
|
replace('\n', '') |
in this code we remove new line symbol |
Next, we wrap the search method from the SerpApi library in a promise to further work with the search results and run it:
const getJson = (params) => {
return new Promise((resolve) => {
search.json(params, resolve);
})
}
getJson(params).then(getNewsData).then(console.log)
Outputs:
