AngularJS App disrupted due to Direct Link to URL containing route parameters

Having an issue with direct links to pages containing a parameter. While links from the page itself work, accessing the page directly or refreshing it causes it to break and not load anything. This problem is occurring within a blog application I am developing.

For example, localhost/blog loads correctly, but when navigating to localhost/blog/name-of-article directly, it fails to load. The Chrome Javascript console displays the error "Uncaught SyntaxError: Unexpected token < " for all javascript files. There is also a problem when the URL has a trailing "/" which could be related to Angular issues.

Here is a snippet of relevant code from my routes:

app.config(['$routeProvider','$locationProvider',
  function($routeProvider,$locationProvider){

    $routeProvider.
        when('/',{
        templateUrl: '/partials/home.html',
            controller: 'HomeController as HomeCtrl'

        }).
        when('/home',{
            templateUrl: '/partials/home.html',
            controller: 'HomeController as HomeCtrl'
        }).
        when('/blog',{
            templateUrl: '/partials/blog.html',
            controller: 'BlogController as blogCtrl'
        }).
        when('/blog/:name', {
            templateUrl: '/partials/article.html',
            controller: 'ArticleController as articleCtrl'

        }).
        otherwise({
            redirectTo: '/'
        });

         $locationProvider.html5Mode(true);

}]);

The server-side is built using Node/Express, serving an API for the Angular app.

app.use('*', function(req, res){
  res.sendFile(__dirname + '/public/index.html');
  console.log('page loaded');
});

Additional routes are set up for /api/contact and /api/article.

Answer №1

I finally discovered the reason behind the issue I was experiencing. It turns out that the Angular app was sending requests to the server using a different path when there was a trailing slash or an extra parameter. For example, when trying to access /blog/article, it was actually requesting files from /blog/javascripts, /blog/stylesheets, and so on, which did not exist.

The solution was simple:

<base href="/index.html">

Adding this line to the index.html file resolved the problem completely.

Answer №2

If your default HTML page, let's call it index.html, is located at the root directory and all other dependencies are inside a folder named /src, you can configure your Express server to handle requests in a specific way.

To ensure that requests targeting www.example.com/src are served resources from the /src folder in the root directory, you can add the following configuration line to your Express server:

var staticDirectory = "/src";
app.use('/src', express.static(__dirname + staticDirectory));

All other requests should return the index.html file.

By setting up your Express server this way, any requests not pointing to /src will automatically return the index.html file. You can apply similar configurations for other folders containing static content if needed.

Your Express configuration file should resemble the following:

var express = require('express');
var app     = express();
var staticDirectory = "/src";    
app.use('/src', express.static(__dirname + staticDirectory));
app.get('/*', function(req,res){
    res.sendFile(__dirname + '/index.html');
});
app.listen(9000, function(){
    console.log('Express server is listening on 9000. Yayy!');
})

This setup should effectively address your issue. I have tested this configuration with a structure similar to this one.
