Read on to find out how to leverage all the goodness in Vuex using a more natural and convenient API, making your app easier to reason about and refactor.
Would you like to prevent problems and regressions? Refactor with confidence? Save development time? Make any area of the app accessible to other developers?

One of the nicest bits of syntax sugar in Ruby are keywords.
In this short post we will explore the keyword operator in Ruby, and a few things you should have in mind when first getting started with it.

In our team, we always use trailing…
BetterSettings is a settings-management library for Ruby apps, which was designed in response to certain issues we faced when using settingslogic (one of the most popular libraries to manage settings in Rails applications).

When providing services to different companies or customers with the same software, such as enterprise or white-label applications, it’s not unusual that each customer uses different terminology for certain concepts within the application.
…Mongoid provides support for MongoDB’s Aggregation Framework, but writing raw queries can be confusing and is extremely verbose:
Product.collection.aggregate [
{ '$match' => { 'country' => 'US' } },…Like most object-oriented languages, Ruby has both instance and class variables. The syntax is @name for instance variables, and @@name for class variables.
Let’s look at a simple…
In this post we take a look at effective ways to reduce the amount of watchers in our AngularJS application and improve the performance of our app.
AngularJS might not be hip anymore, but it’s still a useful framework to create interactive web apps. In this post we will take a brief tour through Angular’s internals: watchers and the digest cycle.
Cucumber steps often involve asserting a condition or the opposite of it. For example:
Then(/^I should see a "(.*?)" comment$/) do |message|
expect(page).to have_css('li.comment', text: message)

Bash is the default terminal for most Unix distributions, so it’s very appealing to get the best out of it. If you enjoy customizing your setup, you might want to try something like zsh instead, which comes with similar functionality ou…
Blocks are a very unique part of Ruby’s syntax, but sometimes it can be tedious to write a block to perform a simple method call. An extremely common idiom in Ruby uses symbols to specify the method that should be called, but.. how does it work?
Mongoid is not designed for extensibility; if you need to modify its behaviour in a slight way, you will probably have no choice but to monkey-patch it.
A while ago I was working on a feature that required displaying information from several mongodb collections. The performance was pretty bad, since for each item being displayed it was necessary to traverse nested and polymorphic associations to get the rest of the data.…
One of the downsides of using an ORM is that it abstracts the queries in a way that it’s difficult to understand which queries are being performed; it’s harder to notice inefficient queries, since we didn’t actually write them!
A performance issue that is very common when using ORMs is the N+1…
