CSS3 right offset

Did you realised that when you need to place your background image on the right side and it always touches the corner of the right, CSS3 to save, you can actually do a offset of right by doing this:

.class {
  background-position:right 10px center; // this will offset a 10px from right side.
}

Display all products in woocommerce admin

Woocommerce is good start for ecommerce beginners, easy to install and get start with, I was using CSV importer to import thousands of SKU however I realised that it will not update the current tax that you have. So in order to fix that we need to update the tax again in each product, you can do quickly using bulk action, and click Edit

By default woocommerce only allow you to show 20 products per page, you can open up the screen option button at the top right, and change the number of items per page, easy fix.

Add active state on meteor.js menu

Imaging you have already created a menu in meteor js framework, somewhere in your header, something like this

<ul>
 	<li><a href="/home">Home</a></li>
 	<li><a href="/about-us">About Us</a></li>
 	<li><a href="/contact-us">Contact Us</a></li>
</ul>

SO you want to make the menu to be active when you are on current route, one of the simple solution is to create a template helper, Register a template helper by adding a file on client folder called helper.js

then inside helper.js register a template helper (Template.registerHelper), which previously called UI.registerHelper.

 

Template.registerHelper('isActive', function(){ // take in some params to determine the stats
  // assume that you are using iron-router, if not please install "meteor install iron:router"
  var currentRoute = Router.current().route.getName();
  if(currentRoute == parms){
    return "current";
  }
})

with this helper, you can add to your template.

 

<ul>
 	<li class="{{isActive "><a href="/home">Home</a></li>
</ul>

// Notice the home as argument which you defined on your iron router name.
<ul>
 	<li class="{{isActive "><a href="/about-us">About Us</a></li>
 	<li class="{{isActive "><a href="/contact-us">Contact Us</a></li>
</ul>

 

now your li class will return active when you are on that page/route.

Becareful with jquery on or bind event.

When you do jQuery and sometime you would bind some functions on an event outside appended DOM elements, and rerun the function again like this:

<ul>
 	<li>test</li>
 	<li>test</li>
 	<li>test</li>
</ul>
<button></button>

for example we want to change the text to something else when we click on each of the li, maybe lets change to “run test …”;

function changeText(){
  $(this).find('p').text("run test");
}

$('li').on('click', changeText);
//$('li').bind('click', changeText);

now you want append a new li and allow function on that appended li like this:

Meteor include external javascript or other files

When I first start meteor i found it hard to load external libraries like javascript files, especially when you bought some templates somewhere, which contains more than 5 javascript files and 4 css files.

A few solution I tired was using some external library loader, such as IRLibLoader, its pretty easy to use inside your router, call this method

IRLibLoader.load('/js/whatever.js')

will this seems to work fine at first, when first load its working the javascript initialised, however when i refresh and or navigate around and backĀ again its not working, the script inside this does not initialed.

So the better solution to load this when page rendered, in template js file,

 

Template.templateName.rendered= function(){
  $('body').append('<script src="/js/whatever.js">');
}

 

Meteor 1.0++ seems to able to put external tags inside the body tag, you can just include the external libraries into template tag

Gulp error tracking

If you are using Gulp for you workflow, there might be chance when you have some error, gulp will stop, and you rerun gulp again, wow thats really kills your productivity, especially sometime you don’t see the reflection on your browser and you seems can’t figure out whats wrong until you go check your terminal.

there is a gulp plugin called gulp-plumber helps when you do not want to break your gulp and print the error on console.

its really easy, just install and include in your gulp pipe like this.
First, install gulp-plumber as a development dependency:

npm install --save-dev gulp-plumber

Then, add it to you gulpfile.js:

var plumber = require('gulp-plumber');
var coffee = require('gulp-coffee');

gulp.src('./src/*.ext').pipe(plumber())
.pipe(coffee())
.pipe(gulp.dest('./dist'));

Remove sudo meteor
