I'm using Yeoman and the angular-fullstack generator to bootstrap an angular app. When I do grunt serve or grunt serve:dist everything works as expected.
Now the question is, when I open the index.html file directly in the browser, isn't it supposed to work equally?
So I have a hard time understanding whats tasks grunt is executing here to make it work. Or maybe I am missing something else.
The console tells me:
GET file:///app/8d57a97f.app.css net::ERR_FILE_NOT_FOUND
GET file:///app/47ab0f3e.vendor.js net::ERR_FILE_NOT_FOUND
GET file:///app/01b9b8a8.app.js net::ERR_FILE_NOT_FOUND
The generated index.html looks something like this:
<!doctype html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<base href="/">
<title></title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" href="app/8d57a97f.app.css"/>
</head>
<body ng-app="myApp">
<!-- some functionality... -->
<script src="app/47ab0f3e.vendor.js"></script>
<script src="app/01b9b8a8.app.js"></script>
</body>
</html>
The reason why I do this:
I try to run the angular app with phonegap on an android device. When I load it to the android mobile, the screen remains blank. So I opened it in the browser and got the same result.
So this is my first attempt to solve this issue.
The problem was the <base href="/"> in the header.

Hi I am new to React and recently built my app which was working fine locally but when my colleagues deployed it on the azure , we are facing this issue.
I tried looking for answers in stackoverflow itself but it was associated with changing webpack.config.js file which looks nothing like my config file which is in node_modules/react-scripts/config. So no idea how to solve it. Here is my public/index.html file
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<title>Booking System</title>
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
<!--
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
You can add webfonts, meta tags, or analytics to this file.
The build step will place the bundled scripts into the <body> tag.
To begin the development, run `npm start` or `yarn start`.
To create a production bundle, use `npm run build` or `yarn build`.

</body>
</html>
I have a build a React application and deployed it on Heroku. When I try to load my home page "/" I get no errors and the page loads perfectly. But when I try to navigate to a different page "/RegistrationList" I get the Content Security Policy errors:
I have already searched for a solution online and found that I need to specify a Meta tag in the index.html file inside the public folder of my application. So now this file looks as follows:
!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
http-equiv="Content-Security-Policy"
content="default-src * 'self' 'unsafe-inline' 'unsafe-eval'"
/>
<link
rel="stylesheet"
href="https://fonts.googleapis.com/icon?family=Material+Icons"
/>
<link
href="https://fonts.googleapis.com/css2?family=Titillium+Web:ital,wght#0,400;0,700;1,400&display=swap"
rel="stylesheet"
/>
...
But at this point I still keep on getting the errors. The strange thing is that the main page ("/") loads perfectly and the second page gives these errors.
Your current CSP within the index.html is useless under a security point of view (you are allowing everything, so this is equivalent as not defining a CSP).
CSP can be defined either in your front-end (index.html) and back-end, and when there is a mismatch, you find all kinds of errors. If you try to remove the CSP meta tag from your index.html and you still get the error, it means the problem is in the server side.
In case of Apache server, this is located in file 'htaccess'. As for Heroku, I don't know exactly where it is. Perhaps this can work:

I was using the CDN release of office-js, but had to change to a local version. After this change, it seems Office.initialize is not being run, which means the add-in doesn't work correctly. On the console, I see the following error:
SCRIPT5022: MicrosoftAjax.js is not loaded successfully.
office.js (18,26767)
The only references to MicrosoftAjax.js that I can find are ASP.NET related, but my project is Typescript/React. Here's how office.js is being loaded in the html:
<!doctype html>
<html lang="en" data-framework="typescript">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>wincross-formatter</title>
</head>
<body class="ms-font-m">
<script src="/assets/office.js"></script>
<div id="container"></div>
</body>
</html>
How can I fix this error?
EDIT:
As per this page, I added the following line just above the office-js script:
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.min.js"></script>
Adding it after the office-js script gives me this error instead of the previous one, and Office.initialize still isn't being called:
SCRIPT5022: Neither the locale, en-us, provided by the host app nor the fallback locale en-us are supported.
FINAL EDIT: That was completely my fault. I didn't copy the contents of office-js/dist recursively.
I've generated angular(2) project and it generated the following index.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>FirstAngular</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
</head>
<body>
<app-root>Loading...</app-root>
</body>
</html>
As you can see no "script" tag to include any JS bundler. I know this project use webpack but I don't see any reference to it in the index.html file.
After running the project everything works fine. I'll love if someone could tell me how this "magic" happens.
Thanks!
This index.html just acts as a template for webpack. Once you do ng serve or ng build the actual index.html will be generated and saved. If you look into the page source code in the browser, you will see the script tags are there.
I can't figure out why I'm getting the ERR_EMPTY_RESPONSES error below. I am working on Chapter 2 of Learning AngularJS by Ken Williamson. I typed in all the code exactly as it is in the book and set up the directory structure exactly as it is listed in the book. However, when I try to run the project (locally on my computer), I get the following error:
Failed to load resource: net::ERR_EMPTY_RESPONSE (22:27:47:397 | error, network)
at http://localhost:8383/AngularJsHelloWorld_chapter2/partials/main.html
Error: [$compile:tpload] http://errors.angularjs.org/1.5.0-rc.0/$compile/tpload?p0=partials%2Fmain.html&p1=-1&p2=
at Error (native)
The code for the relevant pages look like this:
Index.html:
<!DOCTYPE html>
<html lang="en" ng-app="helloWorldApp">
<head>
<title>AngularJS Hello World</title>
<meta name="viewport" content="width=device-width, initial- scale=1.0">

<script src="js/services.js"></script>
</head>
<body>
<div ng-view></div>
</body>
</html>
main.html:
<div>{{message}}</div>
I realize I might need to provide additional information. Any help is appreciated.
Here is a link to the directory structure:
https://library.oreilly.com/book/0636920035831/learning-angularjs/14.xhtml?ref=toc#idp2844416
Here is the code on Github: https://library.oreilly.com/book/0636920035831/learning-angularjs/14.xhtml?ref=toc#idp2844416
By the way, my directory is slightly different from the book in that I have the latest versions of the js framework in it.
This error is caused by a known issue in ngRoute (https://docs.angularjs.org/api/ngRoute):
If ngView is contained in an asynchronously loaded template (e.g. in another directive's templateUrl or in a template loaded using ngInclude), then you need to make sure that $route is instantiated in time to capture the initial $locationChangeStart event and load the appropriate view. One way to achieve this is to have it as a dependency in a .run block: myModule.run(['$route', function() {}]);
Adding the following code should fix the error. It did for me when opening the web page locally.
helloWorldApp.run(['$route', function() {}]);
