SerpApi for JavaScript/TypeScript

npm version Deno version Build status License SerpApi Libraries

Scrape and parse search engine results using SerpApi. Get search results from Google, Bing, Baidu, Yandex, Yahoo, Home Depot, eBay and more.

🪧 Coming from google-search-results-nodejs?
Check out the migration document to find out how to upgrade.

Quick start

Node.js

Ensure you’re running at least Node.js v16.14.

npm install serpapi
import { getJson } from "serpapi";
const response = await getJson("google", {
  api_key: API_KEY, // Get your API_KEY from https://serpapi.com/manage-api-key
  q: "coffee",
  location: "Austin, Texas",
});
console.log(response);

Deno

Import directly from deno.land. Usage is otherwise the same as above.

import { getJson } from "https://deno.land/x/serpapi/mod.ts";

Features

Configuration

You can declare a global api_key and timeout value by modifying the config object. timeout is defined in milliseconds and defaults to 60 seconds.

All functions, other than getLocations, accepts an optional api_key and timeout that will take precedence over the values defined in config.

getLocations doesn’t require an API key.

import { config, getJson } from "serpapi";

config.api_key = API_KEY;
config.timeout = 60000;

await getJson("google", { q: "coffee" }); // uses the API key defined in the config
await getJson("google", { api_key: API_KEY_2, q: "coffee" }); // API_KEY_2 will be used

Pagination

Search engines handle pagination in several different ways. Some rely on an “offset” value to return results starting from a specific index, while some others rely on the typical notion of a “page”. These are often combined with a “size” value to define how many results are returned in a search.

This module helps you handle pagination easily. After receiving search results from getJson, simply call the next() method on the returned object to retrieve the next page of results. If there is no next() method, then either pagination is not supported for the search engine or there are no more pages to be retrieved.

const page1 = await getJson("google", { q: "coffee", start: 15 });
const page2 = await page1.next?.();

You may pass in the engine’s supported pagination parameters as per normal. In the above example, the first page contains the 15th to the 24th result while the second page contains the 25th to the 34th result.

Note that if you set no_cache to true, all subsequent next() calls will not return cached results.

Refer to the getJson definition below for more examples.

Functions

Table of Contents

getJson

Get a JSON response based on search parameters.

  • Accepts an optional callback.
  • Get the next page of results by calling the .next() method on the returned response object.

Parameters

  • engine string engine name
  • parameters object search query parameters for the engine
  • callback fn? optional callback

Examples

// single call (async/await)
const json = await getJson("google", { api_key: API_KEY, q: "coffee" });

// single call (callback)
getJson("google", { api_key: API_KEY, q: "coffee" }, console.log);
// pagination (async/await)
const page1 = await getJson("google", { q: "coffee", start: 15 });
const page2 = await page1.next?.();
// pagination (callback)
getJson("google", { q: "coffee", start: 15 }, (page1) => {
  page1.next?.((page2) => {
    console.log(page2);
  });
});
// pagination loop (async/await)
const organicResults = [];
let page = await getJson("google", { api_key: API_KEY, q: "coffee" });
while (page) {
  organicResults.push(...page.organic_results);
  if (organicResults.length >= 30) break;
  page = await page.next?.();
}
// pagination loop (callback)
const organicResults = [];
getJson("google", { api_key: API_KEY, q: "coffee" }, (page) => {
  organicResults.push(...page.organic_results);
  if (organicResults.length < 30 && page.next) {
    page.next();
  }
});

getHtml

Get a HTML response based on search parameters.

  • Accepts an optional callback.
  • Responds with a JSON string if the search request hasn’t completed.

Parameters

  • engine string engine name
  • parameters object search query parameters for the engine
  • callback fn? optional callback

Examples

// async/await
const html = await getHtml("google", { api_key: API_KEY, q: "coffee" });

// callback
getHtml("google", { api_key: API_KEY, q: "coffee" }, console.log);

getJsonBySearchId

Get a JSON response given a search ID.

  • This search ID can be obtained from the search_metadata.id key in the response.
  • Typically used together with the async parameter.
  • Accepts an optional callback.

Parameters

  • searchId string search ID

  • parameters object (optional, default {})

    • parameters.api_key string? API key
    • parameters.timeout number? timeout in milliseconds

  • callback fn? optional callback

Examples

const response = await getJson("google", {
  api_key: API_KEY,
  async: true,
  q: "coffee",
});
const { id } = response.search_metadata;
await delay(1000); // wait for the request to be processed.

// async/await
const json = await getJsonBySearchId(id, { api_key: API_KEY });

// callback
getJsonBySearchId(id, { api_key: API_KEY }, console.log);

getHtmlBySearchId

Get a HTML response given a search ID.

  • This search ID can be obtained from the search_metadata.id key in the response.
  • Typically used together with the async parameter.
  • Accepts an optional callback.

await delay(1000); // wait for the request to be processed.

// async/await
const html = await getHtmlBySearchId(id, { api_key: API_KEY });
