server db

server: db

This module provides server-side access to the synchronized data stores. For each happening, there are several different stores available:

• shared, synchronized across all devices of all happening members,
• admin, synchronized across all devices of all happening admins,
• personal, synchronized across all devices of a single happening member; note that this is not a single data store, but in fact one store for each member, and
• backend, not synchronized, only available to your backend code.

Data in any of these stores can only be modified by your server-side plugin code. Client-side code can read and observe the data though, subject to the above limitations of course.

Objects

shared

An Observable that maps to the root of the shared store.

admin

An Observable that maps to the root of the shared admin store.

Functions

personal(memberId)

Returns a Observable that maps to the root of the personal store for the given member id.

Example

Example:

server.coffee:
	Db = require 'db'

	exports.client_add = (data) !->
		# allocate a the next id; when `maxId` isn't set yet, this will set and return 1
		id = Db.shared.incr 'maxId'

		# add entree to the list
		Db.shared.set 'items', id, data

client.coffee:
	Dom = require 'dom'
	Ui = require 'ui'
	Modal = require 'modal'
	Server = require 'server'

	Dom.section !->
		Dom.h4 "A shared list"
		Ui.list !->
			Db.shared.iterate 'items', (myItem) !->
				Ui.item !->
				Dom.text myItem.get()
			Ui.bigButton "Add", !->
				Modal.prompt "Add new item", (value) !->
					Server.call 'add', value
