Advanced Features Guide

Welcome to the Advanced Features section of our documentation. Here, we delve into the more intricate capabilities of our platform, designed to empower experienced users and developers to maximize their productivity and leverage the full potential of our tools.

Dynamic Querying

This section covers how to construct dynamic queries based on user input or external data. This allows for highly flexible data retrieval and manipulation.

Using Wildcards

Wildcards like % and _ can be used to match patterns within your queries. The % wildcard matches any sequence of zero or more characters, while the _ wildcard matches any single character.

Example: Finding users whose names start with 'A'

You can achieve this using a LIKE clause:

SELECT * FROM users WHERE name LIKE 'A%';

Parameterized Queries

To prevent SQL injection vulnerabilities and improve performance, always use parameterized queries. This involves separating the SQL command from the data values.

Example: Securely searching by email

Using placeholders (syntax may vary by language/library):

SELECT * FROM users WHERE email = ?;

The actual email address would be passed as a parameter separately.

Custom Event Handling

Learn how to define and respond to custom events within the application. This is crucial for building reactive and interactive user interfaces.

Defining Custom Events

Custom events can be dispatched using a simple event bus or a dedicated event emitter.

// Example using a hypothetical event bus
        eventBus.dispatchEvent('custom:dataLoaded', { userId: 123, data: [...] });

Subscribing to Events

Register listeners for specific events to trigger actions when they occur.

// Example using a hypothetical event bus
        eventBus.addEventListener('custom:dataLoaded', (event) => {
            console.log('Data loaded for user:', event.detail.userId);
            renderData(event.detail.data);
        });
Pro Tip: Organize your events logically and use clear naming conventions to avoid conflicts and improve maintainability. Consider a namespace for your custom events, e.g., myApp:userLoggedIn.

Background Task Management

Offload computationally intensive or time-consuming operations to background tasks to keep your application responsive.

Creating Background Jobs

We support asynchronous task execution using a robust job queue system. Refer to the API Reference for detailed job creation methods.

Monitoring Job Status

Track the progress and status of your background jobs through our dashboard or programmatic APIs.

You can check job status using an identifier returned upon job submission:

const jobId = backgroundTask.createJob('process_large_file', { filePath: '/path/to/file.csv' });
        // Later, to check status:
        const status = backgroundTask.getJobStatus(jobId);
        console.log(`Job ${jobId} status: ${status}`);

Extending Functionality with Plugins

Discover how to develop and integrate custom plugins to extend the core functionality of the platform, tailoring it to your specific workflow.

Plugin Architecture

Our plugin architecture is designed for modularity and ease of integration. Each plugin typically exposes specific functions or hooks that can be invoked by the core application.

Developing a Simple Plugin

A basic plugin might look like this:

// plugins/myCustomPlugin.js
        export const myCustomPlugin = {
            name: 'MyCustomPlugin',
            version: '1.0.0',
            register: (app, options) => {
                console.log('MyCustomPlugin registered with options:', options);
                app.addFeature('customWidget', () => 'This is a custom widget!');
            }
        };

Plugins can be registered during application initialization. Consult the Plugin API for more details on lifecycle hooks and available extension points.
