Overview of Announcement Banner System

Purpose

The Announcement Banner System is designed to display sticky notices on dashboards or course views. Its primary goal is to capture user attention for disseminating important information such as news updates, system notifications, and critical alerts.

Benefits

• Sticky Positioning: Banners remain visible at the top of the screen regardless of scrolling.
• Customizable Appearance: Utilizes HTML and CSS for tailored designs without compromising layout.
• Multiple Banners Support: Ability to display several banners on a single page as needed.
• Cross-Platform Consistency: Ensures a uniform user experience across different platforms or devices.
• Seamless Integration: Easily integrates with existing UI frameworks, enhancing the user interface without disruption.

Usage Scenarios

1. System-Wide Messages: Ideal for broadcasting updates, maintenance schedules, and other critical system information.
2. Course-Specific Notifications: Inform users about course-related changes or important deadlines.
3. Time-Sensitive Information: Display alerts for upcoming events, deadlines, or real-time updates.
4. User-Specific Alerts: Notify users of pending actions, achievements, or personalized updates.

This module offers a flexible and robust solution for developers to enhance user communication within their applications, ensuring messages are seen and acted upon promptly.

Persistent Sticky Banners

Banners are designed to remain visible until explicitly dismissed by the user. They stick to the screen, ensuring important messages aren’t missed.

Banner Types

Supports multiple banner types (info, warning, error), each with distinct styling and priority levels for clear visual communication.

Customizable Positioning

Administrators can set banner positions (top, bottom, floating) based on user experience requirements and layout constraints.

Branding Integration

Banners support custom colors, fonts, and logos to align with the platform’s branding, ensuring consistent visual identity.

Management API

A RESTful API provides CRUD operations for managing banners programmatically. Developers can create, update, or delete banners through code.

Filtering and Search

Administrators can filter banners by type, status, or content using search parameters, simplifying management of large banner sets.

Performance Optimizations

Banners are optimized to load quickly with minimal impact on page load times, ensuring seamless user experience.

Content Management

Supports rich text formatting and HTML embedding for creating complex or visually appealing announcements.

Multi-Language Support

Banners can display content in multiple languages, catering to a diverse user base.

Expiry Dates

Banners automatically expire after a specified duration, preventing clutter on dashboards and course views.

User Interaction Analytics

Track banner interactions (clicks, dismissals) to gather insights into user behavior and optimize messaging strategies.

Integration Hooks

Provides hooks for integrating with other modules or systems, ensuring seamless integration within existing platforms.

React UI Component

Announcement Banner Component

import React, { useState, useEffect } from 'react';

interface Announcement {
    id: number;
    title: string;
    content: string;
    start_date: string;
    end_date: string;

const AnnouncementBanner = () => {
    const [announcements, setAnnouncements] = useState<Announcement[]>([]);
    const [searchQuery, setSearchQuery] = useState('');

    useEffect(() => {
        fetch('/api/announcements/')
            .then(response => response.json())
            .then(data => setAnnouncements(data.data))
            .catch(error => console.error('Error fetching announcements:', error));
    }, []);

    const filteredAnnouncements = announcements.filter(announcement =>
        announcement.title.toLowerCase().includes(searchQuery.toLowerCase()) ||
        announcement.content.toLowerCase().includes(searchQuery.toLowerCase())
    );

    return (
        <div className="announcement-banner-container">
