Local Notification Configuration Data Structure

Overview

Local notification purpose is to notify users to sue the mobile app for better learning experience.
Here user will get notification on timely basis, and the notification will be purely locally generated. For this, when the user installs the application and run it for the first time, based on certain configurations a notification event will be set on a particular date* and time*, which will be triggered at specified time with some message*.

Proposed Design

We're proposing the data structure for configuring the local notification.

Solution 1:

A notification will be triggered on every Tuesday at 7:30 PM (19:30) from the next coming Tuesday onwards.

And will be repeated 4 time only, after which there won't be any notification.

[
  {
     time: "19:30",
     day: "Tuesday",
	 repeat: 7
     occurrence: 4,
     title: "{\"en\":\"Message\"}",
     msg: "{\"en\":\"Description for Notification\"}"
  }
]

Property	type	Value (Example)	Description
time	string	20:15	time in 24 hours
day	string	"Tuesday"	any day of week ["Moday", "Tuesday"... "Sunday"] Note: either of `day` or `date`
date	int	14	date of the month [1-31] Note: either of `day` or `date`
repeat	int	5	number of days notification to be repeated
occurrence	int	10	number of time to repeat the notification
title	string		Tittle for notification
msg	string		Description of notification

Solution 2:

A)

A notification will be triggered on every month 20th at 7:00 PM (19:00) from the next coming date.

And will be repeated monthly, till the given date in `endRepeat` i.e 20 May 2019

{
  time: "19:00",
  date: 20,
  repeat: "monthly",
  endRepeat: {
    date: "20/05/2019"
  }
  title: "{\"en\":\"Message\"}",
  msg: "{\"en\":\"Description for Notification\"}"
}

B)

A notification will be triggered on every day at an interval of 5 days at 10:00 AM (10:00).

And will be occurring for next 6 weeks, after which notification will stop.

{
  time: "10:00",
  interval: 5,
  endRepeat: {
    weeks: 6
  }
  title: "{\"en\":\"Message\"}",
  msg: "{\"en\":\"Description for Notification\"}"
}

Property	type	Value (Example)	Description
time	string	20:15	time in 24 hours
day	string	"Tuesday"	any day of week ["Monday", "Tuesday"... "Sunday"] Note: either of `day` or `date`
date	int	14	date of the month [1-31] Note: either of `day` or `date`
repeat	string	monthly	repeat pattern
	string	weekly
	string	yearly
	string	daily
title	string		Tittle for notification
msg	string		Description of notification
endRepeat	object		object with some properties

For repeat object:

Property	type	Value (Example)	Description
months	int	4	after N number of months should stop notification Note: if given then `day` should be a date of a month, example: 20
weeks	int	5	after N number of weeks should stop notification Note: if given then `day` should be in weekday, example: "Tuesday"
days	int	3	after N number of days should stop notification Note: if given then `day` and `repeat` should not be provided
repeatCount	int	10	should be repeated for N number of times only

Pros and Cons

Solution	Pros	Cons
1	Simple logic not too many conditions for calculating date.	While setting passing the values we've to calculate the number of occurrences based on when and how long we want to continue the notification.
2	Has just have to pass the values it'll automatically calculate the occurrences and stop if required.	Logic will be complex and have to take care of each every value which needs to be passed.

Using In App Notification Payload

After the discussion, we'll be using the same payload structure as described in In App Notification.

{
"id": 1, // id of the notification will be integer, which will be unique
"type": 1, // Notification type will be integer - Their can different notification types, like DOWNTIME, GREETINGS, NON-DISPLAY and OTHERS
"data":{ // action data contains all the information related to type of the notification, start, msg, notification title
	"en": {
	"title": "Title text",
	"msg": "Descriptive message"
	}
}
}

Property	type	Value (Example)	Description
id	int		id of the notification will be integer, which will be unique
type	enum		Notification type will be integer - Their can different notification types, like DOWNTIME, GREETINGS, NON-DISPLAY and OTHERS
data	obj	translations	Object specifying the language, Example `en`
	obj	interval	Interval specifies the time interval difference between 2 notification. Example, for weekly once value should be `7`.
	obj	start	Date and time from when the notification will be triggered for the first time. `Format "14/05/2019 12:00" or "Tuesday 12:00"`
	obj	occurrence	Number of times the notification should be triggered, if `null` then notification will be shown infinite times on the specified date and time

Translations object contains object with these properties with key specifying language code

Property	type	Value (Example)	Description
en	obj	title	Title of notification, should be string
	obj	msg	Description of notification, should be string
hi	obj	title	Title of notification, should be string
	obj	msg	Description of notification, should be string
