i have tryied these two models of .htacess on public/.htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . /index.html [L]
</IfModule>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.html [QSA,L]
but it doesn't works too.
Server
const root = require('path').join(__dirname, 'client', 'build')
app.use(express.static(root));
app.get("*", (req, res) => {
res.sendFile('index.html', { root });
})
i don't have any webserver, sorry, but im a student, and im still learning...
please help guys!

If you using Create React App check your build/asset-manifest.json if have correct paths to the files. If not, change them manually or - what is better - change or set "homepage" value in package.json to proper one. And last tip - read carefully whole output of npm run build - it helped me. Whole bugfinding spends me 3 hours :(

you add the line of code below to index.html in the public folder
<base href="your root path">
Or you can refer to the link below:

In angular js after reloading page it say error on server 404 can not found the page after using $locationProvider.html5Mode(true);

I use
$locationProvider.html5Mode(true); to remove # from url
http://seagullinteractive.com/#/about :-its work after reload
to
http://seagullinteractive.com/about :- its not work dont now the problem

You need to create .htaccess file in your root directory.
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*) /index.html [NC,L]
Need to put above rewrite rules. Then it will be fine. When you call http://seagullinteractive.com/about then your server will look for directory with name "about" which actually will not exist and you will get 404 as a result. You need to redirect to index.html(or whichever is your page that contains ng-app) if there is no resource found on server with requested URI.

AngularJS - Remove hash # using $locationProvider

I used $locationProvider to remove hashtag # from this url
http://localhost/angular-phonecat/app/#/phones
using the following code:
phonecatApp.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
$routeProvider.
when('/phones', {templateUrl: 'partials/phone-list.html', controller: 'PhoneListCtrl'}).
when('/phones/:phoneId', {templateUrl: 'partials/phone-detail.html', controller: 'PhoneDetailCtrl'}).
otherwise({redirectTo: '/phones'});
$locationProvider.html5Mode(true);
}]);
and in index.html added this in the head
<base href="/angular-phonecat/app/">
this worked and my current url is:
http://localhost/angular-phonecat/app/phones
But when I directly access this url it is not showing the webpage because it is not calling the index.html file. Instead, it is showing the contents of /app/phones directory
I tried by creating an .htaccess file also
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^(/index\.php|/img|/js|/css|/robots\.txt|/favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ./index.html [L]

There is a small error in your rule, the rewrite rule requires one more parameter.
Furthermore, when you write RewriteCond %{REQUEST_FILENAME} !-d you prevent redirection if a directory with this name exists. Since /anular-phonecat/app/phones exist you need to also remove this line.
You dont need the RewriteCond %{REQUEST_URI} !^(/index\.php|/img|/js|/css|/robots\.txt|/favicon\.ico) condition, since files won't be redirecte thanks to the RewriteCond %{REQUEST_FILENAME} !-f condition
The result is:
RewriteEngine On
RewriteBase /angular-phonecat/app/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* ./index.html [L]

AngularJs Routes and Refreshing

Routes is what I am using in AngularJs to load dynamic content through an ajax calls asynchronously. This is how I do that:
var $app = angular.module('app', ['ngRoute']);
$app.config(["$routeProvider", "$locationProvider", function ($routeProvider, $locationProvider) {
$routeProvider
.when("/pop", {controller: "popCtrl", templateUrl: "partials/pop_test.html"})
.when("/dashboard", {controller: "dashBoardCtrl", templateUrl: "partials/dashboard.html"})
.otherwise({redirectTo: "/"})
$locationProvider.html5Mode(true);
}])
I also have a mini nav set up so that when I click on my links it loads those partials through the templatrUrl parameter
<ul>
<li>Home</li>
<li>Pop</li>
<li>Dashboard</li>
</ul>
This is all working great, when I click on my links it loaded the content I have set up in pop_test.html and dashboard.html
Now the problem that I am having.
When you click on the link for lets say dashboard the content loads just fine through ng-view and the routes work great BUT if the user reloads or refreshes the page and you're on lets say localhost/dashboard it will actually try to go to that link and locate a file named after whatever you have after / which in this case is a directory called dashboard.
So how can I make it so when the user refreshes or reloads the page he doesn't actually reload the /dashboard page therefor not getting a server error page not found.

As Alberto mentioned, the server needs to know what to do. In Angular's case, everything needs to be routed through the index.html when using $locationProvider.html5Mode(true); otherwise you'll run into what you are now.
To fix this you need to add a Server Rewrite rule which you can find an explanation of it, along with the different server versions, in ui-router's docs here.
You can also add a .htaccess file with the rewrite rules for index.html like so:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*) /index.html [NC,L]

fuelphp routes to angular routes

I have routes and request handling mechanism written in fuelphp to calculate the template in server side.
Computing templates on server side is slower in my understanding and I would like to covert all routes to angular routing.
Most of the fuelphp code outputs angularjs views.
Is there a direct or quicker way to convert all php routes to angular routes.

Try this:
In your public folder make a .htaccess file and fill it with the following
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</IfModule>
