Introduction
Welcome to the user documentation for the Core Module. This module forms the foundational layer of our system, providing essential services and functionalities that underpin all other components. Understanding the Core Module is crucial for effective use and development with our platform.
This documentation aims to provide a comprehensive guide for users, developers, and administrators. We will cover everything from basic concepts to advanced usage and integration patterns.
Getting Started
To begin using the Core Module, follow these steps:
- Installation: Ensure the Core Module is installed and configured according to the system's setup guide.
- Initialization: Learn how to initialize the module and make its services available to your applications.
- First Steps: A simple walkthrough to perform a basic operation, demonstrating the module's responsiveness.
Prerequisites
- A working environment with the necessary dependencies installed.
- Basic understanding of [Relevant Technology, e.g., Object-Oriented Programming, REST APIs].
Core Concepts
The Core Module is built around several fundamental concepts:
1. Services
The module exposes various services for managing data, handling requests, and orchestrating operations. Each service has a specific purpose and a well-defined interface.
2. Events
The Core Module utilizes an event-driven architecture. Understanding how events are published, subscribed to, and handled is key to building reactive applications.
3. Configuration
Learn how to configure the Core Module to suit your specific needs, including settings for performance, security, and resource management.
4. Data Management
Details on how the Core Module handles data persistence, retrieval, and transformation. This includes information on supported data formats and strategies.
API Reference
This section details the public API of the Core Module. All interactions with the module should ideally go through these interfaces.
Service: UserManager
Manages user accounts, authentication, and authorization.
Method: createUser(userData)
Creates a new user account.
// Example usage in JavaScript
coreModule.services.userManager.createUser({
username: "john_doe",
email: "john.doe@example.com",
password: "securePassword123"
})
.then(user => console.log("User created:", user))
.catch(error => console.error("Error creating user:", error));
| Parameter | Type | Description |
|---|---|---|
| userData | Object | An object containing user details. |
Method: getUserById(userId)
Retrieves a user by their unique identifier.
coreModule.services.userManager.getUserById("user-123")
.then(user => console.log("User found:", user))
.catch(error => console.error("Error fetching user:", error));
| Parameter | Type | Description |
|---|---|---|
| userId | String | The unique ID of the user. |
Examples
Illustrative examples showcasing common use cases of the Core Module.
Example 1: Authenticating a User
This example demonstrates how to authenticate a user using their credentials.
async function authenticateUser(username, password) {
try {
const session = await coreModule.services.auth.login(username, password);
console.log("Authentication successful. Session token:", session.token);
return session;
} catch (error) {
console.error("Authentication failed:", error.message);
throw error;
}
}
authenticateUser("admin", "password");
Troubleshooting
Common issues and their solutions.
Issue: Service unavailable
Symptom: Received an error indicating a service could not be reached.
Solution: Ensure the Core Module is running and properly initialized. Check server logs for detailed error messages.
Issue: Data not saving
Symptom: Changes made to data are not persisted.
Solution: Verify your database connection settings and ensure the user has the necessary permissions. Consult the data management section for specific configurations.
