NPM Setup

npm install primeng --save

It is a very young component library, the development started on January 2016. The development speed is pretty quick and many of the most useful components from PrimeFaces and PrimeUI are already available in PrimeNG. The 1.0 Final version is said to be delivered on 23rd of November.

PrimeNG at the current state of development provides a lot of ready to use components like DataTables, TreeTables, Dialogs, Menus, Charts, Drag&Drop functionality, Inputs (switches, dropdowns, spinners toggles ...) and many more.

Nevertheless, PrimeNG supports JQuery Theme Rolles, so there are many free themes available to customize the look and feel of your application.

Small Discussion about ng-bootstrap?

What is Ng-Bootstrap?

ng-bootstrap is angular directives specific to the Bootstrap 4.
ng-bootstrap is a set of components and directives that wrap the latest version of Bootstrap.This makes it easy to use Bootstrap in your Angular apps.
ng-bootstrap depends on Bootstrap’s CSS being available, but you don’t need the Bootstrap JS or jQuery dependencies.

Npm Command

npm install --save @ng-bootstrap/ng-bootstrap

Example

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
declarations: [AppComponent, ...],
imports: [NgbModule.forRoot(), ...],
bootstrap: [AppComponent]
})

Discussion About Angular 2 Directives?

What are Angular Directives?

Directives are a way to teach HTML new tricks. During DOM compilation directives are matched against the HTML and executed. This allows directives to register behavior, or transform the DOM.

Directives Types

Components
Structural Directives
Attribute Directives

1. Components

Component decorator allows you to mark a class as an Angular component and provide additional metadata that determines how the component should be processed, instantiated and used at runtime.

Components are the most basic building block of an UI in an Angular application. An Angular application is a tree of Angular components. Angular components are a subset of directives. Unlike directives, components always have a template and only one component can be instantiated per an element in a template.

@Component({
selector: 'myApp',
template: `<h1>Query Home</h1>`
})
class homePage{
}

2. Structural Directives

Structural directives are responsible for HTML layout. They shape or reshape the DOM's structure, typically by adding, removing, or manipulating elements.

As with other directives, you apply a structural directive to a host element. The directive then does whatever it's supposed to do with that host element and its descendants.

Example

<div *ngIf="isPageEnable" class="app-name">Query Home</div>

3.Attribute Directives

Attributes directives are responsible for change the appearance or behavior of an element, component, or another directive.

Example

<p appHighlight>Highlight me!</p>

Small Discussion about Thingspeak?

What is ThingSpeak?

ThingSpeak is an open-source Internet of Things (IoT) application and API to store and retrieve data from things using the HTTP protocol over the Internet or via a Local Area Network.ThingSpeak was originally launched by ioBridge in 2010 as a service in support of IoT applications.
ThingSpeak™ is an IoT analytics platform service that allows you to aggregate, visualize and analyze live data streams in the cloud.

ThingSpeak provides instant visualizations of data posted by your devices to ThingSpeak. With the ability to execute MATLAB® code in ThingSpeak you can perform online analysis and processing of the data as it comes in. ThingSpeak is often used for prototyping and proof of concept IoT systems that require analytics.

ThingSpeak allows you to aggregate, visualize and analyze live data streams in the cloud.

Some of the key capabilities of ThingSpeak include the ability to

Easily configure devices to send data to ThingSpeak using popular IoT protocols.
Visualize your sensor data in real-time.
Aggregate data on-demand from third-party sources.
Use the power of MATLAB to make sense of your IoT data.
Run your IoT analytics automatically based on schedules or events.
Prototype and build IoT systems without setting up servers or developing web software.
Automatically act on your data and communicate using third-party services like Twilio® or Twitter®.

Small Discussion about Minikube?

What is Minikube?

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

Minikube supports Kubernetes features such as:

DNS
NodePorts
ConfigMaps and Secrets
Dashboards
Container Runtime: Docker, rkt, CRI-O and containerd
Enabling CNI (Container Network Interface)
Ingress

When using a single VM of Kubernetes, it’s really handy to reuse the Minikube’s built-in Docker daemon; as this means you don’t have to build a docker registry on your host machine and push the image into it -

We can just build inside the same docker daemon as minikube which speeds up local experiments. Just make sure you tag your Docker image with something other than ‘latest’ and use that tag while you pull the image. Otherwise, if you do not specify version of your image,

it will be assumed as :latest, with pull image policy of Always correspondingly, which may eventually result in ErrImagePull as you may not have any versions of your Docker image out there in the default docker registry (usually DockerHub) yet.

Small Discussion about Polymer.Js?

What is Polymer.Js?

Polymer.js is a JavaScript library created by Google that allows reusing the HTML elements for building applications with components. Polymer is an open-source JavaScript library developed by Google developers

Polymer provides a number of features over vanilla Web Components:

Simplified way of creating custom elements
Both One-way and Two-way data binding
Computed properties
Conditional and repeat templates
Gesture events

Polymer.js places a hefty set of requirements on the browser, relying on a number of technologies that are in still in the process of standardization (by W3C) and are not yet present in today’s browsers.

Examples include the shadow dom, template elements, custom elements, HTML imports, mutation observers, model-driven views, pointer events, and web animations. These are marvelous technologies, but at least as of now, that are yet-to-come to modern browsers.

The Polymer strategy is to have front-end developers leverage these leading-edge, still-to-come, browser-based technologies, which are currently in the process of standardization (by W3C), as they become available.

The recommended polyfills are designed in such a way that (at least theoretically) will be seamless to replace once the native browser versions of these capabilities become available.
