richsilv / renderOnce.js

Last active August 29, 2015 13:56

A Meteor.js utility function to easily attach a function to a given template's "rendered" callback but only run it once, on the next render.

	// Useful for occasions on which you know that an action will result in the re-rendering of a template
	// (through invalidation) and you want to execute task(s) once the rendering is complete in response.
	// Sometimes, you only need to execute these task(s) in response to that specific action, so it doesn't
	// make sense to add the task(s) to the normal "rendered" callback and then test if they need to be executed
	// every time the template is rendered.
	renderOnce = function(template, oneTimeFunc, afterwards) {
	// template: either a Meteor Template instance, or the string name of such an instance
	// oneTimeFunc: the function you are attaching to the "rendered" callback to be run only once
	// afterwards: set to true if you need the oneTimeFunc to be executed after the normal "rendered" callback,
	// rather than before it

	var collections = [];
	for (var item in window) {
	if (window[item] && window[item]['_collection']) collections.push(item);

richsilv / ReactiveObject.js

Last active August 29, 2015 14:10

Meteor Reactive Object

	// initial - Initial value (must be an object)
	// name - a name to help identify the object if you're using objectStore
	// objectStore - a central store to push all initialised objects into (for debugging)
	// maxInvalidate - the maximum number of times to invalidate computations which depend
	// on this object. Avoids and helps diagnose infinite invalidation loops in testing.
	//
	// note that setting a sub-key on a key which is currently literal-valued will delete
	// the existing value

	ReactiveObject = function(initial, name, objectStore, maxInvalidate) {

richsilv / debounceWithArgs.js

Last active August 29, 2015 14:10

Mixin for Underscore.js to allow arguments to be passed with each function call. Designed for use with Meteor, but easy to use without either Meteor or Underscore.

	// Underscore mixin to allow arguments to be passed to debounced functions.
	// Useful for updating user doc on keyup (or similar) where doc update will invalidate
	// many dependent computations, and so you only want to actually update it every so often.
	// See below for example.
	// Can also be used without Meteor (change Meteor.setTimeout to Timeout), and without
	// underscore (just make debounceWithArgs a stand-alone function).

	_.mixin({
	debounceWithArgs: function(func, timeOutDuration) {
	var timeOut,

richsilv / methods.js

Last active August 29, 2015 14:13

Demo of the difference in `this` in Meteor methods depending on whether the call was from client or server

	var calledFromServer;

	Meteor.methods({
	'getThis': function() {
	return this;
	},

	'getThisServer': function() {
	return calledFromServer;
	}

richsilv / randomCode.js

Last active August 29, 2015 14:18

Random code generator (numbers and letters) of prescribed format (e.g. Postcode, NI number)

	var randomLetter = function() {return String.fromCharCode(Math.floor(Math.random()*26) + 65);}
	var randomNumber = function() {return String.fromCharCode(Math.floor(Math.random()*10) + 48);};
	var genDict = {
	'l': randomLetter,
	'n': randomNumber
	};

	// pass in a format string of the type: "4l 3n 2l", i.e. a space-delimited set of number/letter
	// pairs, the first of which gives the number of characters of the given type and the second
	// denotes the type: "n" for number, "l" for letter (always upper-case).
