How to add a unique url link foreach category

Hi, I am trying to add a unique url link foreach category

How can I do that in my view?

This is my view:

@extends('layouts.app')

@section('content')
<div class="container">
   <h1>Categories:</h1>
        @foreach ($categories as $category)
        <li>{{ $category->name }}</a></li>
        @endforeach
</div>
@endsection

This is my category controller:

<?php

namespace App\Http\Controllers;

use App\Category;
use Illuminate\Http\Request;

class CategoryController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {
      $categories = Category::all();
      return view('categories.index', compact('categories'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
      return view ('categories.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
      $categorie= new \App\Category();
      $categorie->name=$request->get('name');
      $categorie->save();

      return redirect('categories');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
      $category = Category::find($id);
      return view('categories.edit',compact('category','id'));
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
      $category = Category::find($id);
      $category->name=$request->get('name');
      $category->save();

      return redirect('categories');
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}
