<code>@Input()</code> works on if you call a component(child component) from another component(parent component.

You can pass the user object like this.

<pre><code>&lt;child-component [user]="userObject"&gt;&lt;/child-component&gt;

You can encode your object into the string and pass it through the query params.

There is a npm package for Angular which extends router: angular2-navigate-with-data

<a href="https://www.npmjs.com/package/angular2-navigate-with-data" rel="nofollow noreferrer">https://www.npmjs.com/package/angular2-navigate-with-data</a>

I'm using it with Angular 6 and pretty sure it works also with 7.
Example use:

import package in app.module file: <code>import "angular2-navigate-with-data";</code>

<pre class="lang-javascript prettyprint-override"><code>import {Router} from '@angular/router';

class PageOne {
 constructor (private router: Router){}

 public redirect() {
 this.router.navigateByData({
 url: ["/PageTwo"],
 data: [1,2,3,4,5], //data - &lt;any&gt; type
 //extras: {} - &lt;NavigationExtras&gt; type, optional parameter
 });
 }
}


import {Router} from '@angular/router';
import {OnInit} from "@angular/core";

class PageTwo implements OnInit {
 constructor (private router: Router){}

 public ngOnInit() {
 console.log(this.router.getNavigatedData()); //output [1,2,3,4,5]
 }
}
</code></pre>

I wanted to pass one object with routerLink. I found lot but, didn't get any satisfied answer. I am new to angular.

user.component.html

<pre><code>&lt;button type="button" routerLink="/admin"&gt;Add Event&lt;/button&gt;
</code></pre>

user.component.ts

<pre><code>export class UserComponent implements OnInit {

 @Input()
 public user: UserOperator = new UserOperator({});
</code></pre>

I wanted to pass above user object to with button routerLink.

app.module.ts

<pre><code>const appRoutes: Routes = [
 { path: 'admin', component: AdminComponent },
]
</code></pre>

I am working on Angular 7. 
Any help would be greatly appreciated.
