## Full code

If you don't need an explanation, have a look at [the full code example in the online IDE](https://replit.com/@MikhailZub/Scrape-Apple-App-Store-Product-and-Reviews-NodeJS-SerpApi#index.js)

```javascript
import dotenv from "dotenv";
dotenv.config();
import { getJson } from "serpapi";

const getSearchParams = (searchType) => {
  const isProduct = searchType === "product";
  const reviewsLimit = 10; // hardcoded limit for demonstration purpose
  const engine = isProduct ? "apple_product" : "apple_reviews"; // search engine
  const params = {
    api_key: process.env.API_KEY, //your API key from serpapi.com
    product_id: "1507782672", // Parameter defines the ID of a product you want to get the reviews for
    country: "us", // Parameter defines the country to use for the search
    type: isProduct ? "app" : undefined, // Parameter defines the type of Apple Product to get the product page of
    page: isProduct ? undefined : 1, // Parameter is used to get the items on a specific page
    sort: isProduct ? undefined : "mostrecent", // Parameter is used for sorting reviews
  };
  return { engine, params, reviewsLimit };
};

const getProductInfo = async () => {
  const { engine, params } = getSearchParams("product");
  const json = await getJson(engine, params);
  delete json.search_metadata;
  delete json.search_parameters;
  delete json.search_information;
  return json;
};

const getReviews = async () => {
  const reviews = [];
  const { engine, params, reviewsLimit } = getSearchParams();
  while (true) {
    const json = await getJson(engine, params);
    if (json.reviews) {
      reviews.push(...json.reviews);
      params.page += 1;
    } else break;
    if (reviews.length >= reviewsLimit) break;
  }
  return reviews;
};

const getResults = async () => {
  return { productInfo: await getProductInfo(), reviews: await getReviews() };
};

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

```

## Why use [Apple Product Page Scraper](https://serpapi.com/apple-product) and [Apple App Store Reviews Scraper](https://serpapi.com/apple-reviews) APIs from SerpApi?

Using an API generally solves all or most problems that might be encountered while creating your own parser or crawler. From a webscraping perspective, our API can help to solve the most painful problems:

- Bypass blocks from supported search engines by solving CAPTCHA or IP blocks.
- No need to create a parser from scratch and maintain it.
- Pay for proxies, and CAPTCHA solvers.
- Don't need to use browser automation if there's a need to extract data in large amounts faster.

Head to the [Apple Product Page playground](https://serpapi.com/playground?engine=apple%5Fproduct) and [Apple App Store Reviews playground](https://serpapi.com/playground?engine=apple%5Freviews) for a live and interactive demo.

## Preparation

First, we need to create a Node.js\* project and add [npm](https://www.npmjs.com/) packages [serpapi](https://www.npmjs.com/package/serpapi) and [dotenv](https://www.npmjs.com/package/dotenv).

To do this, in the directory with our project, open the command line and enter:

```bash
$ npm init -y

```

And then:

```bash
$ npm i serpapi dotenv

```

\*If you don't have Node.js installed, you can [download it from nodejs.org](https://nodejs.org/en/) and follow the installation [documentation](https://nodejs.dev/learn/introduction-to-nodejs).

- SerpApi package is used to scrape and parse search engine results using SerpApi. Get search results from Google, Bing, Baidu, Yandex, Yahoo, Home Depot, eBay, and more.
- dotenv package is a zero-dependency module that loads environment variables from an `.env` file into `process.env`.

Next, we need to add a top-level "type" field with a value of "module" in our `package.json` file to allow [using ES6 modules in Node.JS](https://nodejs.org/api/packages.html#determining-module-system):

![ES6Module](https://user-images.githubusercontent.com/64033139/206865580-6b5326ee-ff65-4890-876e-78112047a03f.png)

For now, we complete the setup Node.JS environment for our project and move to the step-by-step code explanation.

## Code explanation

First, we need to import `dotenv` from [dotenv](https://www.npmjs.com/package/dotenv) library and call [config()](https://www.npmjs.com/package/dotenv#user-content-config) method, then import `getJson` from [serpapi](https://www.npmjs.com/package/serpapi) library:

```javascript
import dotenv from "dotenv";
dotenv.config();
import { getJson } from "serpapi";

```

- `config()` will read your `.env` file, parse the contents, assign it to `process.env`, and return an Object with a `parsed` key containing the loaded content or an `error` key if it failed.
- `getJson()` allows you to get a JSON response based on search parameters.

Next, we write `getSearchParams` function, to make the necessary search parameters for two different APIs. In this function, we define and set `isProduct` constant depending on the `searchType` argument.

Next, we define and return different search parameters for Product Page API and Reviews API: search `engine`; how many reviews we want to receive (`reviewsLimit` constant); search parameters for making a request:

```javascript
const getSearchParams = (searchType) => {
  const isProduct = searchType === "product";
  const reviewsLimit = 10; // hardcoded limit for demonstration purpose
  const engine = isProduct ? "apple_product" : "apple_reviews"; // search engine
  const params = {
    api_key: process.env.API_KEY, //your API key from serpapi.com
    product_id: "1507782672", // Parameter defines the ID of a product you want to get the reviews for
    country: "us", // Parameter defines the country to use for the search
    type: isProduct ? "app" : undefined, // Parameter defines the type of Apple Product to get the product page of
    page: isProduct ? undefined : 1, // Parameter is used to get the items on a specific page
    sort: isProduct ? undefined : "mostrecent", // Parameter is used for sorting reviews
  };
  return { engine, params, reviewsLimit };
};

```

When we run this function, we receive different search parameters for:

- Product Page API:  
![product api](https://user-images.githubusercontent.com/64033139/206909475-36569bfa-8a1c-47f7-92bf-264762d138e0.png)
- Reviews API:  
![reviews api](https://user-images.githubusercontent.com/64033139/206909548-6693e5dc-f93e-4002-9c35-4e5d48ca9602.png)

You can use the next search params:

Common params:

- `api_key` parameter defines the SerpApi private key to use.
- `product_id` parameter defines the ID of a product you want to get the reviews for. You can get the ID of a product from our [Web scraping Apple App Store Search with Nodejs](https://serpapi.com/blog/web-scraping-apple-app-store-search-with-nodejs) blog post. You can also get it from the URL of the app. For example  
`product_id` of "<https://apps.apple.com/us/app/the-great-coffee-app/id534220544>", is the long numerical value that comes after "id", `534220544`.
- `country` parameter defines the country to use for the search. It's a two-letter country code. (e.g., `us` (default) for the United States, `uk` for United Kingdom, or `fr` for France). Head to the [Apple Regions](https://serpapi.com/apple-regions) for a full list of supported Apple Regions.
- `no_cache` parameter will force SerpApi to fetch the App Store Search results even if a cached version is already present. A cache is served only if the query and all parameters are exactly the same. Cache expires after 1h. Cached searches are free, and are not counted towards your searches per month. It can be set to `false` (default) to allow results from the cache, or `true` to disallow results from the cache. `no_cache` and `async` parameters should not be used together.
- `async` parameter defines the way you want to submit your search to SerpApi. It can be set to `false` (default) to open an HTTP connection and keep it open until you get your search results, or `true` to just submit your search to SerpApi and retrieve them later. In this case, you'll need to use our [Searches Archive API](https://serpapi.com/search-archive-api) to retrieve your results. `async` and `no_cache` parameters should not be used together. `async` should not be used on accounts with [Ludicrous Speed](https://serpapi.com/plan) enabled.

Product Page params:

- `type` parameter defines the type of Apple Product to get the product page of. It defaults to `app`.

Reviews params:

- `page` parameter is used to get the items on a specific page. (e.g., `1` (default) is the first page of results, `2` is the 2nd page of results, `3` is the 3rd page of results, etc.).
- `sort` parameter is used for sorting reviews. It can be set to: `mostrecent` (Most recent (default)) or `mosthelpful` (Most helpful).

Next, we declare the function `getProductInfo` that gets all product information from the page and returns it. In this function we receive and [destructure](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring%5Fassignment) `engine` and `params` from `getSearchParams` function with `"product"` argument. Next, we get `json` with results, delete unnecessary keys, and return it:

```javascript
const getProductInfo = async () => {
  const { engine, params } = getSearchParams("product");
  const json = await getJson(engine, params);
  delete json.search_metadata;
  delete json.search_parameters;
  delete json.search_information;
  return json;
};

```

Next, we declare the function `getReviews` that gets reviews results from all pages (using pagination) and return it:

```javascript
const getReviews = async () => {
  ...
};

```

In this function we need to declare an empty `reviews` array, receive and [destructure](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring%5Fassignment) `engine`, `params` and `reviewsLimit` from `getSearchParams` function without arguments, then and using [while](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/while) loop get `json` with results, add `reviews` from each page and set next page index (to `params.page` value).

If there are no more results on the page or if the number of received results is more than `reviewsLimit` we stop the loop (using [break](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/break)) and return an array with results:

```javascript
const reviews = [];
const { engine, params, reviewsLimit } = getSearchParams();
while (true) {
  const json = await getJson(engine, params);
  if (json.reviews) {
    reviews.push(...json.reviews);
    params.page += 1;
  } else break;
  if (reviews.length >= reviewsLimit) break;
}
return reviews;

```

And finally, we declare and run the `getResults` function, in which we make an object with results from `getProductInfo` and `getReviews` functions. Then we print all the received information in the console with the [console.dir](https://nodejs.org/api/console.html#consoledirobj-options) method, which allows you to use an object with the necessary parameters to change default output options:

```javascript
const getResults = async () => {
  return { productInfo: await getProductInfo(), reviews: await getReviews() };
};

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

```
