## I. How to Search using Keywords in AliExpress

Searching the AliExpress Search Engine Results Page (SERP) with keywords is a straightforward process. Here are the steps to search for products on AliExpress using keywords:

1. **Visit AliExpress:** Open your web browser and go to the AliExpress website (www.aliexpress.com).
2. **Enter Keywords:** On the AliExpress homepage, you'll find a search bar at the top. Enter your desired keywords in this search bar. These keywords should describe the product you're looking for. For example, if you're searching for "red sneakers," simply type "red sneakers" in the search box.
3. **Click "Search":** After entering your keywords, click on the "Search" button or hit "Enter" on your keyboard. AliExpress will then process your search query.
4. **Browse Search Results:** The AliExpress SERP will display a list of products that match your keywords. You can scroll through the search results to explore different products. The results will include images, product titles, prices, seller ratings, and other relevant information.

Browsing through individual products on AliExpress is a walk in the park. Yet, when you're faced with the daunting task of sifting through thousands of keywords and extracting data from the search results, things can take a turn toward the tedious. How do you tackle this challenge? How do you make it possible to extract product information from AliExpress in the shortest possible time? The solution lies just a scroll away, so keep reading to uncover the secrets.

## II. Project Scope and Structure

Our aim is to ease and scale your process of searching for products in AliExpress, scrape the results, and store them for use. Whether you require data for analytical purposes, market research, or pricing strategies. The project will allow you to input keywords, which are then transformed into valid AliExpress Search Engine Results Page (SERP) URLs. These URLs are then forwarded to the Crawlbase API for efficient web scraping.

To achieve this, we will utilize Postman to accept user input, JavaScript in conjunction with Bun (JavaScript Runtime), Express package, and finally, the Crawlbase Crawling API to crawl and scrape AliExpress. This approach ensures seamless data retrieval while minimizing the risk of being blocked during the scraping process.

Below, you'll find a simplified representation of the project's structure.

## III. Setting Up Your Environment

So, you've got your keywords prepped, and you're all set to dive headfirst into the realm of AliExpress data. But before we proceed on our web scraping adventure, there's a bit of housekeeping to attend to – setting up our environment. It is an essential prep work to ensure a smooth journey ahead.

**1. Acquiring Your Crawlbase JavaScript Token**

To get started, we'll need to create a free [Crawlbase account](https://crawlbase.com/signup/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Crawlbase sign up') and acquire a [JavaScript token](https://crawlbase.com/dashboard/account/docs/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Crawlbase Account Docs'). This token is essential for enabling our efficient data scraping from AliExpress pages, using a [headless browser infrastructure](https://crawlbase.com/docs/crawling-api/headless-browsers/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Headless Infrastructure') and a specialized [Crawling API](https://crawlbase.com/crawling-api-avoid-captchas-blocks/?utm_source=dev.to&utm_medium=referral&utm_campaign=content_distribution 'Crawlbase Crawling API') data scraper designed specifically for AliExpress SERPs.

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/crawlbase-account-docs.jpg)

**2. Establishing Your JavaScript Environment**

Now that you've got that JavaScript token securely in your grip, it's time to set the stage for our coding journey. Begin by creating a new project directory for your scraping application. In this example, we're creating a folder named 'Crawlbase'

```bash
mkrdir Crawlbase
```

**3. Utilizing the Power of Bun**

In this project, we'll be leveraging the power of [Bun](https://bun.sh/docs 'Bun Documentation'), so it's crucial to ensure that you have Bun properly installed. Bun is a versatile, all-in-one toolkit tailored for JavaScript and TypeScript applications.

At the heart of Bun lies the Bun runtime, a high-performance JavaScript runtime meticulously engineered to replace Node.js. What sets it apart is its implementation in the Zig programming language and its utilization of JavaScriptCore under the hood. These factors work in harmony to significantly reduce startup times and memory consumption, making it a game-changer for your development and web scraping needs.

Execute the line below:

```bash
cd Crawlbase && bun init
```

This command is used to initialize a new project with Bun. When you run `bun init` in your command line or terminal, it sets up the basic structure and configuration for your web scraping project. This can include creating directories and files that are necessary for your project to function correctly.

**4. Crawlbase JavaScrip Library and Express**

We're going to introduce two vital libraries: Crawlbase and Express. The [Crawlbase JavaScript library](https://www.npmjs.com/package/crawlbase 'Crawlbase NPM Package') is an absolute gem in this context, allowing us to seamlessly integrate the Crawling API into our JavaScript project and Express is a popular web application framework that we'll use to create our scraping server.

To get these essential libraries added to your project, simply run the following command in your terminal:

```bash
bun add crawlbase express
```

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/terminal-installation.jpg)

With the Crawlbase library and Express now in the mix, you're on your way to unlocking the full potential of the Crawling API and creating a robust scraping application. We're making strides, so stay tuned as we proceed further in this exciting project.

## IV. AliExpress Search Page Scraping Results

Now that the development environment is all set, let’s dive into the core function of our code. You can copy and paste the following code block and understand it by reading the explanation below.

```js
const express = require('express'); // Import the 'express' module
const { CrawlingAPI } = require('crawlbase'); // Import the 'crwalbase' module for Crawling API
const fs = require('fs'); // Import the 'fs' module

// Initializing Crawlbase Crawling API to crawl the HTML
const api = new CrawlingAPI({ token: 'Crawlbase_JS_Token' }); // Replace it with you Crawlbase JS token

// main app
const app = express();
const PORT = process.env.PORT || 3000;

app.get('/scrape-products', async (req, res) => {
  try {
    const response = await api.get(
      `https://aliexpress.com/w/wholesale-${req.query.keywords.split(' ').join('-')}.html`,
      {
        scraper: 'aliexpress-serp',
      },
    );

    if (response.statusCode === 200) {
      const scrapeProducts = response.json.body;
      console.log('Scrape Products:', scrapeProducts);

      // Responding with Scraped JSON
      res.status(200).send(scrapeProducts);
    } else {
      throw new Error(`API request failed with status: ${response.statusCode}`);
    }
  } catch (error) {
    console.error(`API call failed: ${error.message}`);
    return res.status(500).send({ status: 'Failed', msg: 'Data not Saved' });
  }
});

app.listen(PORT, () => console.log(`Server is running on port ${PORT}`));
```

1. We start by importing the necessary modules: `express`, `CrawlingAPI` from Crawlbase, and `fs` for file system operations.
2. We initialize the Crawlbase Crawling API with your Crawlbase JavaScript token. This token grants access to the Crawlbase services.
3. An Express app is created, and we specify the port number for the server. It defaults to port 3000 if not defined in the environment variables.
4. We define a route, "/scrape-products," using `app.get`. This route listens for GET requests and is responsible for the web scraping process.
5. Within this route, we use `api.get` to request the HTML content from an AliExpress URL that is dynamically generated based on the user's search keywords. We replace spaces in the keywords with hyphens to create the appropriate URL structure.
6. We specify the "aliexpress-serp" scraper to instruct Crawlbase to use the AliExpress SERP scraper for this specific URL.
7. If the response from the API has a status code of 200 (indicating success), we extract the scraped product data and log it in the console. The scraped data is then sent back as a JSON response to the client.
8. If the API response has a different status code, an error is thrown with a message indicating the failure status.
9. In the case of any errors or exceptions, we handle them by logging an error message and sending a 500 Internal Server Error response with a message indicating that the data wasn't saved.
10. Finally, we start the Express app, and it begins listening on the specified port. A message is displayed in the console to confirm that the server is up and running.

To execute the app, simply run the command below:

```bash
bun index.js
```

The server is up and running:

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/terminal-server.jpg)
This code sets up a functional web server that can scrape product data from AliExpress search results based on user-defined keywords. It uses the Crawlbase library and Express to provide a simple API endpoint for web scraping, making your project all the more dynamic and interactive.

Now, how will a user enter the keywords exactly? Let’s find out on the next section of the blog.

## V. Accepting Keywords through Postman

After we've set up our web scraping server to extract data from AliExpress search results, it's time to test it out using [Postman](https://www.postman.com/ 'Postman Download'), a popular and intuitive API testing tool.

In this section, we'll show you how to use Postman to send keyword queries to our `/scrape-products` route and receive the scraped data. Keep in mind that you can use any keywords you like for this test. For our example, we'll be searching for "Halloween costumes" on AliExpress.

1. **Open Postman:** If you haven't already, [download and install Postman](https://www.postman.com/downloads/ 'Download Postman'), and fire it up.
2. **Select Request Type:** In Postman, choose the type of HTTP request you want to make. In our case, we'll select "GET" since we're fetching data.
3. **Enter the URL:** In the URL field, enter the endpoint for your scraping route. Assuming your server is running locally on port 3000, it would be something like `http://localhost:3000/scrape-products`. Make sure to adjust the URL according to your setup.

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/postman-url-highlight.jpg)

1. **Add Keywords as a Query Parameter:** To provide keywords for your search, you'll include them as query parameters. In Postman, you can add these parameters to the request URL. For our example, we'll add `keywords` as a parameter with the value "Halloween costumes." In the URL, it will look something like this: `http://localhost:3000/scrape-products?keywords=Halloween%20costumes`.

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/postman-keywords-highlight.jpg)

2. **Send the Request:** Click the "Send" button in Postman to fire off your request. Your server will respond by sending back the scraped data.

![Image description](https://crawlbase.com/blog/aliexpress-search-page-scraping/postman-json-response.jpg)

3. **View the Response:** Postman will display the response in the bottom panel. You should see the scraped data from AliExpress, which can be in JSON format or another format depending on how your server is configured.

That's it! You've successfully used Postman to send keywords to your web scraping server and received the scraped data in response. Remember, you can replace "Halloween costumes" with any keywords you want to search for on AliExpress. This process demonstrates the dynamic nature of your web scraping application, making it adaptable to various search queries.

## VI. Saving the Data to JSON

In our journey of scraping AliExpress search results so far, we've successfully set up our web scraping server and tested it with various keywords using Postman. Now, it's time to enhance our project further by adding a feature to save the scraped data to a JSON file. This step is incredibly valuable as it allows you to store and later analyze the data you've extracted.

We've introduced a crucial addition to the `/scrape-products` route in our code. This addition ensures that the data we scrape isn't just sent in response but also saved in a structured JSON file. Let's evaluate the code.

```js
// Saving the scraped products in JSON file
fs.writeFileSync('AliExpressProducts.json', JSON.stringify({ scrapeProducts }, null, 2));
```

- We use the fs module, which we imported earlier, to write data to a file. In this case, we're creating a new file named "AliExpressProducts.json" in the current working directory.
- `JSON.stringify({ scrapeProducts }, null, 2)` converts our scraped data (in the `scrapeProducts` variable) into a JSON-formatted string. The null, 2 arguments are for pretty printing, which adds indentation for readability.
- The `fs.writeFileSync` method then writes this JSON string to the specified file.

Below is the complete code of our project:

```js
const express = require('express'); // Import the 'express' module
const { CrawlingAPI } = require('crawlbase'); // Import the 'crwalbase' module for Crawling API
const fs = require('fs'); // Import the 'fs' module
// Initializing Crawlbase Crawling API to crawl the HTML
const api = new CrawlingAPI({ token: 'Crawlbase_JS_Token' }); // Replace it with you Crawlbase JS token
// main app
const app = express();
const PORT = process.env.PORT || 3000;
app.get('/scrape-products', async (req, res) => {
  try {
    const response = await api.get(
      `https://aliexpress.com/w/wholesale-${req.query.keywords.split(' ').join('-')}.html`,
      {
        scraper: 'aliexpress-serp',
      },
    );
    if (response.statusCode === 200) {
      const scrapeProducts = response.json.body;
      console.log('Scrape Products:', scrapeProducts);
      // Saving the scraped producrs in JSON file
      fs.writeFileSync('AliExpressProducts.json', JSON.stringify({ scrapeProducts }, null, 2));
      // Responding with Scraped JSON
      res.status(200).send(scrapeProducts);
    } else {
      throw new Error(`API request failed with status: ${response.statusCode}`);
    }
  } catch (error) {
    console.error(`API call failed: ${error.message}`);
    return res.status(500).send({ status: 'Failed', msg: 'Data not Saved' });
  }
});
app.listen(PORT, () => console.log(`Server is running on port ${PORT}`));
```

With this addition, the scraped data will not only be available in real-time responses but also stored in a structured JSON file for future use. It's a crucial step to ensure you can analyze, process, and visualize the data you collect from AliExpress efficiently.
