Use ViewChild directly in JavaScript
import { Component, ViewChild } from '@angular/core';
import { MyComponent } from './my-component.js';
const componentAnnotation = new Component({
selector: "try-view-child-js",
template: `<div><my-component #myComponent></my-component></div>`
});
export class TryViewChildComponent {
@ViewChild('myComponent') _myComp; // QUESTION: How can I use the ViewChild component which reference my component from template in ES6 class?

#credit - @dhavalpowar #Explain how Lets encrypt works

  • Install lets encrypt sudo apt-get install letsencrypt

  • Workflow: lets-encrypt will generate a pair of RSA private key/public key and contact the CA with your public key.

      The CA will register your public key

The program will then ask the CA to verify your domain.
