Workflow, Feed, Messages & Notifications Flow in Novu

​

Fetch Subscriber Feed

A subscriber feed is a list of all In-App messages for a single subscriber. It’s a continuous stream of messages displayed in a list that subscribers can scroll through on the frontend via the Notification Center.

It is a dynamic list with seen and unseen capabilities. Multiple feeds can exist for a subscriber.

The code sample below fetches the list of all In-App messages sent to a specific subscriber:

const { data: inAppMessages } = await novu.subscribers.getNotificationsFeed('subscriberId', {
  page: 0,
  limit: 10,

  // it is of type string. By default all feeds messages are fetched
  feedIdentifier: 'Marketing',

  // seen and read filter of type boolean
  seen: true,
  read: true
});

​

Fetch All Feeds

In-App messages are grouped in Feeds. There can be one or multiple feeds.

The code sample below fetches all the feeds that have been created and exist in the In-App steps:

const { data: feedsData } = await novu.feeds.get();

​

Delete a Message From a Feed

A message is a content sent to a single subscriber over a single channel. Some messages are simple, like SMS, while others have more features and capabilities, such as Email, Chat, In-App.

A single message can be deleted from a Feed. The code sample below shows how to do it:

await novu.messages.deleteById('messageId');

​

Fetch all Messages Sent To All Subscribers

You can retrieve all messages sent to all subscribers. There are a couple of filters you can apply to fetch these messages.

• channel: fetches all messages that were sent via a specific channel, e.g Email, Sms, Push, In-App
• subscriberId: fetches all messages sent to a specific subscriber
• transactionIds: fetches all messages via transaction ids.

import { ChannelTypeEnum } from '@novu/node';

// All fields are optional
const listMessagesOptions = {
  // pagination options
  page: 0,
  limit: 20,

  /**
   *  Filter options
   */
  // use ChannelTypeEnum.PUSH for push, ChannelTypeEnum.IN_APP for in-app,
  channel: ChannelTypeEnum.EMAIL, // only email type messages will be fetched
  subscriberId: '6444105141ffb0919496dfcb',
  transactionIds: ['644-41051-41ffb0-919496-dfcb'],
};

const { data: messagesData } = await novu.messages.list(listMessagesOptions);

​

Mark an In-App Message as Read/Seen

You can mark an In-App message as read/seen. Messages from other channels: Email, Push, Chat, Sms can’t be marked as read/seen.

const { data: markMessageAsRead } = await novu.subscribers.markMessageRead(
  'subscriberId',
  'messageId'
);

const { data: markMessageAsSeen } = await novu.subscribers.markMessageSeen(
  'subscriberId',
  'messageId'
);

​

Mark an In-App Message as Read/Unread/Seen/Unseen

You can mark an In-App message as read/unread/seen/unseen. Messages from other channels: Email, Push, Chat, Sms can’t be marked as read/unread/seen/unseen.

const { data: markMessageAs } = await novu.subscribers.markMessageAs(
  'subscriberId',
  'messageId',
  { seen: true, read: false }
);

​

Mark all In-App Messages as Read/Unread/Seen/Unseen

You can mark all In-App messages as read/unread/seen/unseen.

Messages from other channels: Email, Push, Chat, Sms can’t be marked as read/unread/seen/unseen.

import { MarkMessagesAsEnum } from "@novu/node"

const { data: markAllInAppMessages } = await novu.subscribers.markAllMessagesAs(
   'subscriberId',

   // can be filtered with feed identifiers
   feedIdentifier: ['Marketing', 'Product']

   // MarkMessageAsEnum.READ => It will mark all messages as read
   // MarkMessageAsEnum.SEEN => It will mark all messages as seen
   // MarkMessageAsEnum.UNREAD => It will mark all messages as unread
   // MarkMessageAsEnum.UNSEEN => It will mark all messages as unseen
   markAs: MarkMessageAsEnum.Read
);
