Show calendar based on IP Address accessed

[Spinster]

@sdetweil

I tried your code, but find that once I include getip module in config.js, I am not seeing any output for calendar. Is this the expected output. Without getip module, I find that client_ip = document.getElementById("getip is returning null.Please advice

@Spinster
By the way, which client are you using? Electron? Or Browser?

[Spinster]

@MMRIZE Browser as of now.

I also tried using express ipfilter, but the problem is I don’t know how to use it in module.js, it is throwing error saying ipfilter not known etc

[sdetweil]

@Spinster well, here is a working example, in addition to the other code already

watch out if using address AND MM host system not included. as it won’t show either…
one could make the ipaddress in cal a list (of ip addresses) similar to what @MMRIZE does…
I don’t like adding the extra block,
just add the var to the thing that matters…

@Spinster
With getip of @sdetweil and MMM-ModuleMonkeyPatch, I did it. (You don’t have to modify the original source code for future-proof.)

Example.
Server is running on 192.168.178.63 and I run 2 clients on 192.168.178.22 and 192.168.178.63.
Both 2 clients can show different set of calendars.

{
	module: "MMM-ModuleMonkeyPatch",
	config: {
		patches: [
			{
				module: "calendar",
				method: "socketNotificationReceived",
				patch: async function (original, args) {
					const [ notification, payload ] = args
					if (notification === "CALENDAR_EVENTS") {
						const calendarName = this.config.calendars.find((cal) => cal.url === payload?.url)?.name
						const r = await fetch('http://192.168.178.63:8080/modules/getip')
						const ip = JSON.parse(await r.text())?.[ 'address' ] ?? null
						if (!this.config.clientMap?.[ ip ]?.includes(calendarName)) {
							return original(notification, { ...payload, events: [] })
						}
					}
					return original(notification, payload)
				}
			}
		]
	}
},
{
	module: "getip",
},
{
	module: "calendar",
	header: "US Holidays",
	position: "top_left",
	config: {
		clientMap: {
			"192.168.178.63": [ "cal1", "cal2", "cal3" ],
			"192.168.178.22": ["cal3", "cal4", "cal5"]
		},
		calendars: [
			{
				url: "...",
				name: "cal1",
			},
			{
				url: "...",
				name: "cal2",
			},
			{
				url: "...",
				name: "cal3",
			},

			{
				url: "...",
				name: "cal4",
			},
			{
				url: "...",
				name: "cal5",
			}
		]
	}
},

TO Improve
Whenever notification CALENDAR_EVENTS coming, getip is called. After first execution, to store IP on the localStorage or cookie would be better.

@sdetweil will express ipfilter be useful? Similar to whitelist, can we try something

[sdetweil]

@Spinster no… as its in the wrong place… (inside node_helper…) we NEED the ip address to compare with

just get it and return . one time

@MMRIZE said in Show calendar based on IP Address accessed:

(You don’t have to modify the original source code for future-proof.)

BUT you are fetching cal for system not going to use it… SOME cals are 1000’s of entries especially old
that have to be processed… this is a bad waste of resources…

and this exposes a cal problem, as if u fetch http://xyz on client 1 and client 2 and client 3, we fetch it 3 times. also bad
this could also lead to different clients showing different data between fetchIntervals…

I Can’t understand your point.
My code is just small injection that does filtering out calendars by condition on socketNotificationReceived. No additional fetching is needed.
