A step-by-step guide to integrating a third party widget with Angular

We’ll learn how to set up mapping between Angular input bindings and the widget’s configuration options and how to expose the widget’s API through an Angular component. In short, it defines:

Here’s a very basic configuration that demonstrates the usage of grid options:

Once the JavaScript data grid is initialized:

attaches the object with API methods to the that can be used to control the JavaScript data grid:

However, when ag-Grid is used as Angular component, we don’t instantiate the datagrid directly. The following example demonstrates how Angular wrapper grid is configured in a template using input bindings and output events:

Since Angular assigns an instance of the component to a template reference, which in this case is , the APIs exposed by is accessible through the component. We need to copy all configuration options from the component class properties defined as input bindings to this object. Since we need to pass a native DOM element to the data grid when it’s being instantiated, we grab the element in the component’s constructor:

Once the grid is initialized, we need to track changes to input bindings to update configuration options of the datagrid. Continue reading


Styling An Angular Application With Bootstrap

Let’s see how we can integrate Bootstrap CSS styles and JavaScript files with an Angular project generated using the Angular CLI, and how to use form controls and classes to create beautiful forms and how to style HTML tables using Table styles. Next, install Bootstrap 4 and jQuery from npm:

Finally, open the file and add the file paths of Bootstrap CSS and JS files as well as jQuery to the and arrays under the target:

Check out how to add Bootstrap to an Angular 6 project for options on how to integrate Bootstrap with Angular. After creating a project and adding Bootstrap 4, we’ll create an Angular service that will be used to provide some demo data to display in our application. Next, open the file and add:

Next, open the file and add:

Next, open the file and replace its contents with the following:

We’re creating an application shell by using the header and footer components which means that they will be present on every page of our application. You should see the following interface:

If you navigate to the Contacts page, you should see:

If you navigate to the “Create contact” page, you should see:

In this tutorial, we’ve seen how to create a simple Angular application with a Bootstrap interface. Continue reading


14 tips for developing AngularJS applications – Kiuwan

An insight into some AngularJS concepts, such as $scopes, two-way data binding and directives, will bring us some important tips to keep in mind while developing AngularJS applications. Key features are two-way data binding, built-in dependency injection, templates written with HTML and facilities for unit testing of every component in the application. Keep scopes under control:

Two-way data binding in AngularJS is a cool feature. In order to improve your application performance:

AngularJS directives are great. To make your upgrading easier:

Last but not least, organize your code:

Stay tuned, soon you will have a set of new specific rules for AngularJS applications available in Kiuwan Code Analysis  These rules will help you to follow best practices and enjoy building great AngularJS applications. Continue reading


Static Site Generators: A Beginner’s Guide — SitePoint

A great option for you is to build your website using static site generators (SSG). On the other hand, a static site generator:

takes a different approach and generates all the pages of the website once when there’s actually changes to the site. React, Webpack, modern JS, CSS, etc. all ready for you to just start coding your site

Gatsby’s rich plugin ecosystem allows you to use any kind of data you prefer from one or more sources

Easy deployment and scalability, which is mainly due to the fact that Gatsby builds static pages, which don’t require complicated setups

Gatsby is a Progressive Web Apps (PWA) generator. To install VuePress globally, just run this command in your terminal:

npm install -g vuepress

Then, to create a markdown file, run:

echo '# Hello VuePress' README.md

To start writing, run:

vuepress dev

To build your site, run:

vuepress build

Here are some great features that VuePress has to offer:

Setting up your VuePress-based site is quick and you can write your content using Markdown

VuePress is built on Vue, which means that you can enjoy the web experience of Vue, Webpack, the possibility of using Vue components inside Markdown files and of developing custom themes with Vue

Fast loading experience: VuePress static sites are made of pre-rendered static HTML and run as a SPA once they’re loaded in the browser

Multilanguage support by default with i18n. With regard to stuff like great documentation, strong community and support, all of the static site generators I listed figure among the most popular, or rapidly gaining in popularity like VuePress. Continue reading


Angular Reactive Forms: Tips and Tricks – Netanel Basal

There might be cases when we don’t want to invalidate the form just because a single control is invalid. In this instance we can set the onlySelf property to true, which means that each change only affects the control itself alone, and not its parents. Preventing Infinite Loops
In the process of setting up our form controls, we might inadvertently cause infinite loops. That’s helpful, but sometimes we want to tell Angular that this control is disabled on the initialization face. Pay attention that we must also pass the value property; otherwise Angular assumes that we want the control’s value to be { disabled: true }. Continue reading
