How do I use catbox-memory

[ShayBox]

I'm trying to setup a basic catbox cache that stores the output for a few seconds in memory, nothing too advanced, as far as I can tell I need @hapi/hapi, @hapi/catbox, and @hapi/catbox-memory.

const server = new Server({
	port,
	cache: {
		name: 'realtime',
		engine: require('@hapi/catbox'),
	},
});

const realtimeCache = server.cache({
	cache: 'realtime',
	expiresIn: 1000,
	segment: 'realtime',
	generateFunc: () => device.getPowerUsage(),
	generateTimeout: 2000,
});

server
	.route({
		method: 'GET',
		path: '/tplink/realtime',
		handler: realtimeCache.get('realtime'),
	});

Your engine is wrong. Should be require('@hapi/catbox-memory')

Updated Server

		const server = new Server({
			port,
			routes: {
				cors: true,
			},
			cache: {
				name: 'realtime',
				engine: new catboxEngine(),
			},
		});

Error

EDIT: It is using catbox-memory now, it said it needed to be constructed

[hueniverse]

What version of hapi are you on? See hapijs/hapi#3871 for info on how to configure the cache.

[ShayBox]

    "@hapi/catbox-memory": "^4.1.0",
    "@hapi/hapi": "^18.3.1",
    "@types/hapi__catbox-memory": "^4.1.0",
    "@types/hapi__hapi": "^18.2.1",

It should be the correct version of catbox-memory for hapi

[ShayBox]

I changed it to the example on that page

		const server = new Server({
			port,
			routes: {
				cors: true,
			},
		});

		server.cache.provision({
			provider: {
					constructor: require('@hapi/catbox-memory'),
					options: {
							partition: 'x',
							maxByteSize: 10000,
					},
			},
			name: 'countries',
	});

		const realtimeCache = server.cache({
			cache: 'countries',
			expiresIn: 1000,
			segment: 'realtime',
			generateFunc: () => device.getPowerUsage(),
			generateTimeout: 2000,
		});

		server
			.route({
				method: 'GET',
				path: '/tplink/realtime',
				handler: realtimeCache.get('realtime'),
			});

And it still gives this error

EDIT: This is the full code, it would probably help more then just segments https://paste.nomsy.net/obotaweqoy.js

Looks like line 80 in your code, handler is missing () => .

[ShayBox]

I have never seen in any examples seen a handler option, but I'll try when I'm able to.

EDIT: Nevermind, I see what you mean now, I thought you meant my cache needed a handler function but my route was missing the () =>, Thanks it works now 👍
