Question

I just got started with angular js , i tried routing and worked pretty well .The problem is when i refresh the page it is showing 404 error since it is checking in my actual directory rather than checking in routes.

here is the complete code

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular-route.js"></script>

<body ng-app="myApp">

  <base href="/" />

  <a href="blue">blue</a>

  <a href="green">green</a> //blue.html and green.html are in same directory as index.html

  <p>Click on the links to load blue or green.</p>

  <div ng-view></div>

  <script>
    var app = angular.module("myApp", ["ngRoute"]);

    app.config(function($routeProvider, $locationProvider) {
      $routeProvider
        .when("/blue/:name?", {
          templateUrl: "blue.html",
          controller: "blue_control"
        })

        .when("/green", {
          templateUrl: "green.html",
          controller: "green_control"
        })

      $locationProvider.html5Mode({
        enabled: true
      });

    });
    app.controller("blue_control", function($scope) {
      $scope.msg = "this is blue";
    });
    app.controller("green_control", function($scope) {
      $scope.msg = "this is green";
    });
  </script>


</body>

</html>

here are the browser outputs

output

this is when i refresh

error

please provide me with some solution.


Answer

HTML5 mode requires URL rewriting.

From the Docs:

HTML5 Mode

Server side

Using this mode requires URL rewriting on server side , basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base> tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application.

— AngularJS Developer Guide - Using $location (HTML5 Mode Server Side)

For NodeJS and ExpressJS

var express = require('express');
var path = require('path');
var router = express.Router();

// serve angular front end files from root path
router.use('/', express.static('app', { redirect: false }));

// rewrite virtual urls to angular app to enable refreshing of internal pages
router.get('*', function (req, res, next) {
    res.sendFile(path.resolve('app/index.html'));
});

module.exports = router;

For IIS on Windows

<rewrite>
  <rules>
    <rule name="AngularJS" stopProcessing="true">
      <match url=".*" />
      <conditions logicalGrouping="MatchAll">
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
      </conditions>
      <action type="Rewrite" url="/" />
    </rule>
  </rules>
</rewrite>

For apache

RewriteEngine On RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR] 
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]
