In this guide, we will write a check for an empty object in JavaScript. To achieve this we would be using the custom built-in object.keys method. This returns a truthy value if the given object is empty. This is however easily achieved with lodash like so:
In this guide, we will look at how to handle custom emitted events using the vue $emit() function. It’s noteworthy that all vue components have the $emit function and this basically allows us to pass custom events around our component tree. In somewhat simpler terms, the $emi()t function lets us pass functions as props. Say […]
In this guide, we will look at event handling using Vue onclick directive. Say we have an element (supposedly a button) that we want to trigger a function on click, this directive comes in handy. The onclick directive can also be referenced as such:
Core to the simplicity heralded in Vuejs is its router component (Vue router). Apart from offering dynamic routing and allowing the user to pass in params during routing, the router is also capable of allowing one to do a total re-route to a different URL. Vue router redirect example This is similar to what vanilla […]
Vue Refs are instance properties used to make reference to HTML elements in our vue application. In this guide, we will take a look at using $refs in accessing and manipulating DOM elements in vue. We simply changed the value of the input tag by making reference to it. This is similar to what we […]
In this guide, we will look at class binding with the Vue v-bind directive. Class binding comes in handy when we have the need of manipulating an element’s class list. We can either pass an object or array to dynamically toggle a class. Object Syntax The above syntax means that the class active would be […]
Conditionals are a core part of programming languages. The vue framework uses the v-if directive amongst others in handling this. The Vue v-if directive renders a block of code if its directive is truthy. As long as the expression isActive remains truthy, our block keeps displaying. The reverse is the case when it is false.
In this guide, we will be taking a look at how to use the Vue v-on directive. Basically, the v-on directive is used to listen to DOM events and run some JavaScript when they’re triggered. Here’s a sample:
Life cycle hooks are windows to the driving factors of our frameworks. They help us keep track of what happens to our components. Typically, this is when they are created, updated, destroyed or before either happens. Vue Mounted lifecycle hook is a function called after the instance is mounted. It is however worthy of note […]
In this guide, we will be looking at Vue created lifecycle hook. In general, life cycle hooks are windows to the driving factors of our frameworks. In a nutshell, they help us keep track of what happens to our components. This would usually be when they are created, updated, destroyed or before either of the […]
In this article, we will have a general overview/insight into geocoding; forward geocoding, and reverse geocoding. We will go-ahead to build a mini-app that utilizes the concept of reverse geocoding to display specific locations. We would be using mapbox and Nuxtjs primarily to achieve this. In clear terms, Geocoding involves transforming text-based locations into geographic […]
In this article you learn 5 ways to copy an Array in JavaScript, A bulk of the beauty of JavaScript has to lie in its ability to let us do one thing in several ways, using several means. It’s a typical exemplification of the saying;‘There’s more than one way to skin a cat ’. Arrays […]
In this article, we will learn about Dynamic Routing In VueJS. Time and time again, the simplicity heralded in Vuejs has been reiterated. It does go without saying, that it is the bedrock on which the framework was built on. “I would consider it my failure if it takes 3 years to be good at […]
