Highcharts Angular Wrapper – Highcharts

As a convenience to our customers, we wanted to ensure that using Highcharts in an Angular project was as easy as possible. We are therefore happy to present to you our official Highcharts Angular wrapper, which is free to use (please note that using Highcharts for commercial projects require a valid license). Let’s take a quick look at the wrapper along with the included demo app. Continue reading

AngularJS File Upload Example

Here is a step-by-step guide for implementing the file upload functionality in the angular web applications. It will have the following code:

Let’s start building an application to understand the basic building blocks of the file upload functionality in the angular library. The second part is the angular controller used by the application to get access to the files. Continue reading

AngularJS Lowercase Example

Hello readers, in this tutorial, developers will learn what AngularJS is and how to use the lowercase filter in the angular applications. Therefore, let us create a simple application using the lowercase filter in the angular applications. Following is the syntax of using the lowercase filter in angular applications. Continue reading

Adaptive Layout Design – Angular Flex Layout – The Info Grid

Responsive layout is where components and elements of a web page change size and position based on different breaking points – Web apps that adapt to any screen size. Unlike responsive layout, in Adaptive Layouts different components and elements are displayed or hidden on different screen sizes. While responsive design is amazing at what it does, it also has it limits especially trying to fit the same components in a large screen size and an extra small screen size. Continue reading

AngularJS HTTP Get Example

The angular framework provides the services and is used to do the HTTP request to retrieve the desired data from the server. In angular ajax, developers can send the Ajax requests in multiple ways, such as:

is the core angular service used to do the HTTP requests to communicate with the remote servers and retrieve the required data through the browser’s object or the . To access the angular ajax in a controller, developers will have to use the object i.e. service retrieve the data from the server in the following way. Continue reading

Angular patterns 3: flexible and scalable design of complex pages

At first sight, these are the problems that we need to solve, in order to achieve our goal:
Problem 1: I want to be able to instantiate all my brick components, and make them work, without ending up in a super-fat root component that does everythingIn order to solve this problem, we need to group somehow brick components inside different “areas” of the page; each area should receive a different set of data as input, instantiate its own set of brick components, make them work, and send signals to other areas (or to the root component) in response to user interaction. Problem 2: I want to be able to set up easily OnPush change detection strategyThe problem with “brick” components, i.e. reusable components that don’t decide anything about their internal status, is that it’s tricky to implement OnPush change detection on them, without in the same time binding them to the specific implementation of the parent component (hence, losing in reusability). The two components in the gist above behave very similarly, but they receive their inputs in a different way: the first component receives a bare number, while the second receives an object, that has a number among its properties.

React vs Angular 2: Comparison Guide for Beginners

This article aims to provide you some insight into JavaScript by comparing React and Angular 2; two of the most popular JavaScript frameworks today (you can read past comparisons between React and Angular 1; and React and Angular performance comparison). Add some style and provide the adapted index.html file (again, just copy-paste the one found on the Angular guide), and you can run it in the first terminal where you find:

At this point, we already used some TypeScript (and compared to Vanila JS, it provides a better code organization, typing, and annotations; but this is another thing to learn when you get into Angular 2). Angular 2 is, of course, an efficient framework — but my personal preference goes with React for clarity. Continue reading

AngularJS Filters Example

Hello readers, in this basic example, developers will learn what AngularJS is and how to use the angular filters in the angular applications. Following is the basic syntax using the angular filter in an angular application. Following is the syntax of using the currency filter in angular applications. Continue reading

me&mybentley — With an exterior of an 1903 Federation convent,…

With an exterior of an 1903 Federation convent, complemented by a new angular white ceramic brick, steel and glass extension, designed to reference the neighbouring brutalist architecture, @littlealbionguesthouse in Sydney’s vibrant Surry Hills is equals parts eccentric, eclectic and emphatic. With interiors by local-based firms @spacecontroldesign and Archemy, and architecture by @ty. architecture and @shedarchitecture, the hotel comprises of 35 whimsically sophisticated guest rooms, each boasting a unique symphony orchestrated by bold patterns, lively palettes and luscious textures.

I created the exact same app in React and Vue. Here are the differences.

Let’s just quickly look at our input field, then we’ll explain what is going on:
input type="text" v-model="todo"/V-Model ties the input of this field to a key we have in our data object called toDoItem. We essentially have to do three things here:
Firstly, on the element we want to call the function:
class=”ToDoItem-Delete” we have to create an emit function as a method inside the child component (in this case, ToDoItem.vue), which looks like this:
deleteItem(todo) {
this. $emit('delete', todo)
}Along with this, you’ll notice that we actually reference a function when we add ToDoItem.vue inside of ToDo.vue:
ToDoItem v-for="todo in list"
@delete="onDeleteItem" // — this 🙂
:key="" /This is what is known as a custom event-listener. Continue reading

Unit Testing Celery Tasks – Python Celery – The Missing Blog

While you might get away with not writing unit tests for very simple Rest API endpoints, doing the same for celery tasks is recipe for frustration (and disaster). Celery tasks are asynchronous by design and therefore a lot harder to get a grip on using a “development driven development” approach. Some authors recommend calling the Celery task asynchronously and then making the code wait until the task is ready to fetch the result and evaluate the test assertions. Continue reading
