Is Node.js killing PHP? – TFOT

  • In this article, we are going to address one of such burning arguments PHP vs Node.js.
  • So, let us see the battle of Node.js vs PHP and define the winner!
  • At the dawn of its history, PHP coexisted peacefully with JavaScript, but with the start of Node.js the situation changed.
  • In this regard, Node.js is much more productive, as PHP has very limited functionality above its basic server-side development technologies.
  • In this study, one can see that Node.js has progressed up to obscuring PHPs fame, as in most cases JavaScript-based platform undertakes CPU under much less duress than it does.

A Practical Guide to Using and Creating Angular Directives – SitePoint

  • The ngClass directive is a good example of an existing Angular attribute directive: – – p [ngClass]={‘blue’=true, ‘yellow’=false} – Angular Directives Are Cool!
  • But Angular also offers out-of-the-box structural directives, like the ngIf: – – @Component({ – selector: ‘ng-if-simple’, – template: ` – button (click)=show = !
  • To do that, lets navigate to the app.component.ts file and add the following: – – import { Component } from selector: ‘my-app’, – template: `h1 my-errorHello {{name}}/h1`, – }) – export class AppComponent { name = ‘Angular’; } – – The final result looks similar to this: – – -…
  • Lets start with our app.mycustomifdirective.ts file: – – import { Directive, Input, TemplateRef, ViewContainerRef } from selector: ‘[myCustomIf]’ – }) – – export class MyCustomIfDirective { – – constructor( – private templateRef: TemplateRefany, – private viewContainer: ViewContainerRef) { } – – @Input() set myCustomIf(condition: boolean) { – if (condition) {…
  • from Rangle.ios Angular 2 Training – – – Next, we add it to our declarators: – – import { NgModule } from ‘@angular/core’; – import { BrowserModule } from { MyErrorDirective } from { MyCustomIfDirective } from { AppComponent } from imports: [ BrowserModule ], – declarations: [ AppComponent, MyErrorDirective,…

Build a Node.js command-line chat application with Chatkit

  • In the same project, install @pusher/chatkit and jsdom: – npm install –save @pusher/chatkit – npm install –save jsdomTo be clear, in the previous step, we installed the Chatkit server SDK (@pusher/chatkit-server) and here, we install the client Chatkit SDK (@pusher/chatkit-client).
  • Create auser – Before connecting to Chatkit, we must first create a Chatkit user via the server we wrote earlier.
  • To do this, well send a request to the /users route using axios, which is a HTTP client: – npm install –save axiosAfter installing axios, import it: – Then, define a function called createUser: – We can now call this function with the prompted username: – Lets test this out….
  • To do this, we should update the main function in client.js to fetch joinable rooms (getJoinableRooms), and list them alongside the rooms a user has already joined (user.rooms): – The… syntax there is called destructuring, and it provides a succinct way to merge two or more arrays.
  • First, install readline to read input from the user: – npm install –save readlineThen, import it: – Finally, reference it below: – If you run two instances of the client, you should be able to send and receive messages:
