# Script directory structure

## **📁 Required File List (Project Root Directory)**

```
Example using a Python project root directory:
├── main.py                 # Main entry file
├── requirements.txt        # Python dependency list
├── README.md               # Project documentation
├── input_schema.json       # UI Script configuration file
├── sdk.py                  # SDK file
├── sdk_pd2.py
├── sdk_pd2_grpc.py
```

### **Core Entry File**

* [**main.py**](http://main.py) / **main.js** / **main** (depending on project type; currently supports Python, Go, and Node.js)
  * The main entry point of the crawler script
  * The file name **must** be `main` (file extension depends on the language)

### **Dependency Management**

* **package.json** (Node.js projects)
* **requirements.txt** (Python projects)
* Used to declare all dependencies required to run the project

### **Configuration Files**

* **input\_schema.json**
  * UI Script configuration file
  * Defines the input form interface displayed on the platform for the script

### **Documentation**

* [**README.md**](http://README.md)
  * Script functionality documentation
  * Includes usage instructions and important notes

## **🛠️ SDK Functional Modules**

### **1. Environment Parameter Access**

* Retrieve runtime parameters passed during container startup
* Access crawler task configurations, authentication information, and more

### **2. Data Storage**

* Define data table structures (headers)
* Store scraped result data
* Supports batch saving and resumable uploads

### **3. Logging Output**

* Standardized logging interfaces
* Supports multiple log levels (INFO, WARN, ERROR, etc.)
* Logs are automatically collected and displayed by the platform
