Usage

Sending Promotional Notifications

Here’s an example of how to use the eventFeature to send a promotional notification:

Create a file named notify-service.ts:

import { eventFeature, keywords } from 'notify-services';

const SERVER_URL = 'http://localhost:3005';

const main = async () => {
    try {
        await eventFeature.sendNotifyPromotion(SERVER_URL, {
            user_name: 'John Doe',
            heading: 'New Promotion',
            content: 'Check out this exciting offer just for you!',
            call_to_action: 'Click here',
            company_name: 'Company',
            user_id: 3,
            keyword: keywords.NOTIFY_PROMOTION_AGENCY,
        });
    } catch (error) {
        console.error('Error sending notification:', error);
    }
};

main();

In this example:

• sendNotifyPromotion: Sends a promotional notification to the specified server.
• The payload contains details like the user’s name, promotion content, and call-to-action.

Receiving and Managing Notifications

NotifyService also allows you to receive and manage notifications for your users:

import { eventFeature } from 'notify-services';

const SERVER_URL = 'http://localhost:3005';

const main = async () => {
    try {
        // Get notifications for a user
        const user_id = 3; // Replace with the target user ID
        const notifications = await eventFeature.getNotification(
            user_id,
            SERVER_URL,
            { limit: 10, offset: 0 }, // {limit, offset, keyword, type} (keyword use search)
        );
        console.log('Notifications:', notifications);

        // Mark a notification as seen
        const notification_id = 1; // Replace with the target notification ID
        await eventFeature.seenNotification(notification_id, SERVER_URL);
    } catch (error) {
        console.error('Error handling notifications:', error);
    }
};

main();

In this example:

• getNotification: Retrieves notifications for a specific user.
• seenNotification: Marks a notification as seen.
