app-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { RegisterComponent } from './register/register.component';
import { ErrorComponent } from './error/error.component';
import { MatchcenterComponent } from './matchcenter/matchcenter.component';
import { FleshScreenComponent } from './flesh-screen/flesh-screen.component';
import { CricketComponent } from './cricket/cricket.component'
const routes: Routes = [
  {path: '' , component: FleshScreenComponent, pathMatch:'full' },
 { path: 'login' , component:LoginComponent },
 { path: 'register' , component: RegisterComponent },
 { path: 'error' , component: ErrorComponent},
 { path: 'matchcenter' , component: MatchcenterComponent},
 { path: 'matchcenter/cricket' , component: CricketComponent},

@NgModule({

Answer 1

Paths need to start with a forward slash ( / )

Try changing the path configs to this:

{
  path: '/cricket',
  label: 'Cricket'
}, {
  path: '/football',
  label: 'Football'
}, {
  path: '/nba',
  label: 'NBA'
},

Answer 2

create something like that:

<nav>
  <ul>
    <li><a href="" [routerLink]="['/datatable']">datatable</a></li>
    <li><a href="" [routerLink]="['/customer']">Customer</a></li>
    <li><a href="" [routerLink]="['/courses']">Courses</a></li>
    <li><a href="" [routerLink]="['/my-table']">MyTable</a></li>
  </ul>
</nav>

I think you miss the "/" Behined Your path string.

First things first make sure your routes start from /

this.navLinks=[
    { path:'/cricket',label: 'Cricket'},
    { path:'/football',label: 'Football'},
    { path:'/nba',label: 'NBA'},
];

Based on my assumption I guess you want to pass route param to your matchcenter route. Where cricket football nba are dynamic params given to matchcenter route.

To do so make following changes in your route

const routes: Routes = [
    { path: '' , component: FleshScreenComponent, pathMatch:'full' },
    { path: 'login' , component:LoginComponent },
    { path: 'register' , component: RegisterComponent },
    { path: 'error' , component: ErrorComponent},
    { path: 'matchcenter/:type' , component: MatchcenterComponent}
];

You can further get the passed params in MatchcenterComponent using angular ActivatedRoute.

Or else if you dont want route params. You need to define all routes in the routing module. For current scenario you can use

const routes: Routes = [
    { path: '' , component: FleshScreenComponent, pathMatch:'full' },
    { path: 'login' , component:LoginComponent },
    { path: 'register' , component: RegisterComponent },
    { path: 'error' , component: ErrorComponent},
    { path: 'matchcenter' , component: MatchcenterComponent},
    { path: 'matchcenter/cricket' , component: CricketComponent},
    { path: 'matchcenter/football' , component: FootballComponent},
    { path: 'matchcenter/nba' , component: NbaComponent},
];

Answer 4

Your routerLink="{{item.path}}" in your html should be routerLink="['/matchcenter/{{item.path}}']". The / in front makes it go from baseroute.
