google-search-results-nodejs is a MIT-licensed Node.js package that meant to scrape search results from Google, Bing, Baidu, Yahoo and 10+ more search engines with a SerpApi backend. SerpApi provides a Playground to get you started quickly by testing API interactively.

$ npm install google-search-results-nodejsThe following example runs a search for "coffee" using your secret API key which you can find at SerpApi Dashboard page.
Open in the online IDE (Replit).
const SerpApi = require('google-search-results-nodejs')
const search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")
search.json({
q: "Coffee",
location: "Austin, TX"
}, (result) => {
console.log(result)
})
api_key can be set globally using a singleton pattern:
// https://serpapi.com/manage-api-key
const SerpApi = require("google-search-results-nodejs")
const search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")api_key can be read from the environment variable:
const search = new SerpApi.GoogleSearch(process.env.API_KEY);api_key can be provided for each request:
const SerpApi = require("google-search-results-nodejs")
const search = new SerpApi.GoogleSearch()
let result = search.json({
api_key: "<your-serpapi-api-key>", // https://serpapi.com/manage-api-key
q: "Coffee", // search query
location: "Austin, TX", // location of the search
}, (data) => {
console.log(data)

We love open source, continuous integration and Test Driven Development (TDD). We are using Mocha to test our infrastructure around the clock to achieve the best Quality of Service (QoS).

Set your API key:
export API_KEY="<your-serpapi-api-key>"Run all tests:
npm testconst search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")
search.location("Austin", 3, (data) => {
console.log(data)
})Prints the first three (3) locations matching Austin (Texas, Texas, Rochester)

]The first search result returns a search_id which can be provided to get the search result from the archive. The following code will print the search from the archive.
var search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")
search.json({q: "Coffee", location: "Portland" }, (search_result) => {
// search in archive for the search just returned
search.search_archive(search_result.search_metadata.id, (archived_search) => {
console.log(archived_search)
})
})The following code snippet will print your account information.
const search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")
search.account((data) => {
console.log(data)
})This API was developped using basic callback to handle response. Exception are just throw away with interceptor.
If you want to take advantage of the promise to block the request, here is how we'll do:
const util = require('util')
function getJson(parameter, resolve, reject) {
const search = new SerpApi.GoogleSearch("<your-serpapi-api-key>")
try {
search.json(parameter, resolve)
} catch (e) {
reject(e)
}
}
const blockFn = util.promisify(getJson)
blockFn[util.promisify.custom](parameter).then((data) => {
expect(data.local_results[0].title.length).toBeGreaterThan(5)
done()
}).catch((error) => {
console.error(error)
done()
})Practical code example using Google Images API

const params = {
q: searchQuery, // what we want to search

const getJson = () => {
return new Promise((resolve) => {
search.json(params, resolve);
});
};
const getResults = async () => {
const imagesResults = [];
while (true) {
const json = await getJson();
if (json.images_results) {
imagesResults.push(...json.images_results);
params.ijn ? (params.ijn += 1) : (params.ijn = 1);
} else break;
}
return imagesResults;
};
getResults().then((result) => console.dir(result, { depth: null }));Reference:

This API is using callback to run in non-blocking code. Here we are trying to follow the spirit of NodeJS.

For pratical example, you can see the test located under test/ folder.
To run the regression suite.
export API_KEY="your api key"
make testSerpApi keeps error management simple:
- backend service error or search fail.
- client error.
If it's a backend error, a simple error message is returned as string in the server response. If it's a client error, then a SerpApiClientException is raised.
- 2.1
- add support for Naver, HomeDepot, AppleStoreApp, DuckDuckGo
- defeature location if it is not supported by the search engine
- 2.0.1
- fix classes loading.
- 2.0
- Refractor class name: SearchResult -> Search
- 1.2
- stable version to support all the basic search API.
