Angular dependencies not being included from local files - html

I have the following lines on my index.html file to include various dependencies
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>
However, It keep getting the following error.
It seems like it is trying to retrieve angular and other dependencies from localhost.
How do I resolve this error?

Check your server's base filepath, its should be set to a directory level just above bower_components/
Example : if your directory structure is app/bower_components/xx/xx.js, set your server's static serve path to app/
Assuming that you are using node and express as your server, use this link for knowledge on setting static paths.
I don't see any other problem with this. As the error is 404 which means your files are not being located by the server.

check if file are already in the real path, if not, install them with: bower install

Deploying Blazor PWA to server folder, I get errors saying that various files cannot be found

I can deploy to the root of a server (e.g. http://localhost:8008) but I can't deploy to a subfolder (e.g. http://edkolis.com/pwaexperiment/wwwroot/index.html); I get errors loading various files when I try that. Files that are missing include app.css and blazor.webassembly.js:
<link href="css/app.css" rel="stylesheet" />
<script src="_framework/blazor.webassembly.js"></script>
I see there is a <base> tag in the index.html that specifies that all relative URLs should point to the server root:
<base href="/" />
however if I remove this tag I still get the same errors. How can I deploy my Blazor PWA to a subfolder and have it work, and yet also have it work at the root for local testing (i.e. I don't want to hardcode a server URL into the <base> tag)?
The base href must match the actual path you deploy to.
To avoid changing it build-time, update the launchsettings JSON with that folder name so local (dev) runs also use the"production" base path

Index.html without XAMPP

Is it possible to automatically load index.html on a system folder without using XAMPP, IIS or similar?
It is for a school project and I can't use them, so I have to open the file putting the path (C:/...) into the address bar.
I know I could use .htaccess, but I don't know what to write and if it gets read without any web server solutions!
This can get a little tricky... but is possible without any "administrator" privileges, nor without installing anything.
Download Python 3.8.2 - Windows x86-64 embeddable zip file
Create a folder on "python" on the c:\
Extract the "Zip" file into this folder
Change the folder name from "python-3.8.2-embed-amd64" to "python_src"
Create a folder named "python_html"
The folder structure should look like:
c:\python\
c:\python\python_src\
c:\python\python_html\
Create a file named "webserver.py" in the "c:\python\python_html" folder
Place the following code into that file:
#webserver.py
import http.server
import socketserver
PORT = 80
Handler = http.server.SimpleHTTPRequestHandler
with socketserver.TCPServer(("", PORT), Handler) as httpd:
print("serving at port", PORT)
httpd.serve_forever()
Save and close the file
Create index.html file in the "python_html" folder and place the following code in that file:
<html>
<head>
<title>Web Title</title>
</head>
<body>
<h1>Python Web Server File</h1>
<p>Congratulations! The HTTP Server is working!</p>
</body>
</html>
Open the "Command Prompt" and type the following commands
cd\
cd python\python_html\
c:\python\python_src\python ./webserver.py
Open a web browser and navigate to "http://localhost/"
Once you have confirmed this works, you can build an entire website within that "python_html" folder. As long as you don't close the command prompt it will continue acting as a "Web Server".
I know I could use .htaccess
.htaccess is an Apache (Web Server) config file, so unless you have Apache installed (ie. the "A" in XAMPP) then you can't use that. (If .htaccess was available then index.html would likely load automatically anyway.)
On Apache, being able to load index.html by default when requesting a directory requires mod_dir (an Apache module). In this case, mod_dir issues an internal subrequest for the DirectoryIndex - this all requires additional processes.
I can't install extensions... I have to open the file on my school computer
If you can't install anything then you can't do this I'm afraid. You appear to be limited to direct file requests.
When using a webserver (such as Apache or IIS) then you have a differentiation between a URL and a filesystem path. The webserver maps the URL to a filesystem path. Without a webserver you don't have that abstraction.
There are lighter webservers, other than Apache and IIS, but you need to install something extra.
Just give your file(s) meaningful names (ie. not index.html) and use those instead? eg. fox-project.html

Polymer: Failed to load resources after build

I'm new to polymer. I've followed a couple of tutorials to learn the base of the library. However, I always encounter a problem after building the app.
Here is a summary how to reproduce my problem.
polymer --version //returns 1.6.0
mkdir poly-app
cd poly-app
polymer init // Select polymer-2-application
polymer serve --open // works fine
polymer build
polymer serve build/default --open // works fine
Now, I would like to export my code to my web server. I copy paste the content of /poly-app/build/default and I paste it on my web server. When I try to access it, it get errors such as:
Failed to load resource: the server responded with a status of 404 (Not Found)
I found that the problem comes from the following lines of code in /poly-app/build/default/index.html:
<script src="/bower_components/webcomponentsjs/webcomponents-loader.js"></script>
<link rel="import" href="/src/poly-app-app/poly-app-app.html">
In order to fix the problem, I need to remove the first / in the src and href attribute.
<script src="bower_components/webcomponentsjs/webcomponents-loader.js"></script>
<link rel="import" href="src/poly-app-app/poly-app-app.html">
Apparently I need to do this manually every time I build the app. Is there any other way to fix automatically?
Thanks a lot!
I believe you are trying to serve it from a non root path on your website?
In that case you should set the basePath property of the build configuration to the respective path and the generated code should populate the <base> tag with the needed information so the urls are working.

Firebase not running index.html file

I'm a pretty new programmer going through the Firebase tutorial. I have gone through steps 1-5 of the tutorial (https://codelabs.developers.google.com/codelabs/firebase-web/#5). I've added the "Add Firebase to your web app" js code to the html file, and set up the Firebase CLI. However, when I run the firebase server, everything seems to work other than it is not showing the code from the index.html file.
I am in the right directory, and my console says "Server listening at: http://localhost:5000." But, at localhost 5000, it shows a generic "Welcome to Firebase Hosting: You're seeing this because you've successfully setup Firebase Hosting. Now it's time to go build something extraordinary!" box rather than the app interface code in the index.html file. It is the only html file in my directory. It seems like I am missing something very simple. Thank you for your help.
The website shown to you is the index.html from your public folder (or whatever you configured it to be in your firebase.json file).
The culprit might be firebase init. It tries to generate a generic index.html file for you. However, in the latest version, it should at least ask you whether or not to override (which it did not in the past!).
The problem is firebase init being unbelievably crude. It just overrides the index.html file that was in your public folder... no confirmation, no safety net, no nothing.
If you lost, or accidentally let firebase init overwrite, your index.html file, you have to re-produce it somehow. If you do not have a backup of or other means of re-producing your index.html file... well... too bad!
How does the firebase CLI work?
Generally, the steps of a firebase setup go a little like this:
firebase login
firebase init
your-build-command-here # (if you have a build pipeline)
firebase deploy
You only need to do Step #1 (login) the first time when you setup building on that machine (or maybe when a new firebase revision has been released)
You only need to do Step #2 (init) to initialize a new project. That is, when you don't have your firebase.json yet (which will be created by the init command).
To re-deploy, it's simply:
your-build-command-here # (if you have a build pipeline)
firebase deploy
I figured out my answer. The index.html file that was being posted was in the "public" file, which was created during the "firebase init" stage. I replaced that placeholder html file with the one for my app.
Firebase hosting not showing up app?
There might be two reasons for this problem
1st step:
Make sure your public folder (define in your firebase.json) 'dist' containing the index.html hasn't been modified by firebase init command, if yes replace it with your original project index.html
for reference (dist is standard but your may different)
{ "hosting": { "public": "dist"} }
2nd step:
Make sure to configure your base href in project's index.html
as
<base href="https://["YOUR FIREBASE PROJECT NAME"].firebaseapp.com/">
and other bundle files as
<script type="text/javascript" src="https://["YOUR FIREBASE PROJECT NAME"].firebaseapp.com/runtime.a66f828dca56eeb90e02.js">
<script type="text/javascript" src="https://["YOUR FIREBASE PROJECT NAME"].firebaseapp.com/main.2eb2046276073df361f7.js">
3rd step run command - firebase deploy
enjoy ! ;)
New projects
when doing firebase init select the directory which contains the index.html as the public directory.
Existing projects
update firebase.json with
"hosting": {
"public": "dist/directoryThatContainsIndexHtml",
......
}
Edited Original Answer: Available in edit history. Only for testing purposes.!! for production, use the updated version. Contents of dist are rewritten on each build so anything you place #dist are gone each time you build.
For anyone else comming across this.
Try launching in incognito mode - the browser was cached for me.

first of all you need to check your index.html after deployment of project. after these command steps:
firebase login
firebase init
firebase deploy
your real index.html file might be overwrite by firebase generic file that's why the problem is occurred. so change code of index.html after deployment of project. if you see this box on your web page
Tip: copy your complete project anywhere in your PC before deployment.
otherwise check your directory for file path your path of index.html is must correct.
In my case when I run the command ng build --prod it created a sub folder under dist folder. Assume my project name is FirstProject. I can see a sub folder called FirstProject inside dist folder (dist/FirstProject).
Give dist/[subDirectory] as your public directory
What do you want to use as your public directory? dist/FirstProject
This solved my issue
For deploying Angular application to Firebase simple and quick tutorial
you can find here.
During the process of firebase init, type N, when the question
"File dist/index.html already exists. Overwrite?" appears, and your page will be displayed as it should be.
In public folder option write dist/your-folder-name.
This will allow you to render your index file which is in your folder.
npm install -g firebase-tools
firebase login
firebase init
firebase deploy
firebase open

Hosting: Deployed Site
When you build your Angular app, at least with Angular 10, by default Angular creates a folder names dist, containing a folder having the name of the application. For example, this example’s app is named blog-front, so when building the project (ng build or ng build -- prod), Angular will create a folder dist, containing a folder named blog-front:
When you reach the firebase init step asking the public directory, your folder's name should be “dist/blog-front” for this example, or “dist/yourApplicationName” as a general rule :
In my case firebase was using the wrong directory, also see here: firebase CLI didn't recognize the current project directory for 'firebase init'. While I was expecting firebase to put all created files into my project directory it was totally disconnected and put all files into my /Users/MyUserName directoy and deploying the wrong index.html from there.
This is how to fix it (no reinstall of firebase needed as suggested in the linked post):
delete all created firebase files from /Users/MyUserName directoy (.firebaserc, firebase.json, index.html and dist-folder)
run firebase init on project directoy
use dist/projectname as public directory
Configure as a single-page app "Yes"
do not overwrite index.html (if you do, make sure to "ng build" again before deploying)
firebase deploy
By the way, for everyone who is using Angular 7, this tutorial about deploying an angular 7 app to firebase hosting was really helpfull to me.
I faced similar situation. When we run firebase init it asks couple of questions. At that time we mention the directory path from where firebase will take all files to deploy.
Make sure that, directory contain index.html.
Delete the index.html which is present in dist folder.
Then run the following commands:
firebase login
ng build --prod
firebase init
firebase deploy
This Worked for me
First Stop the project and follow these steps
npm install -g firebase-tools
firebase login
firebase init
? Are you ready to proceed? Yes
? Which Firebase CLI features do you want to set up for this folder? Press Space to select features, then Enter to confirm your choices. Hosting: Configure and deploy Firebase Hosting sites
? What do you want to use as your public directory? dist
? Configure as a single-page app (rewrite all urls to /index.html)? Yes
After initialization is completed makesure to delete the created dist file before next steps
ng build --prod
firebase deploy
You are seeing this error because you didn't run the command:
npm run build
make sure you use it before firebase deploy
and also make you are incorrect directory.
execute this after finishing firebase init process.
If you get a public folder with ready index.html by firebase init. You can simply replace that index.html with yours and use the command:
firebase deploy
That should be enough to get it working. Make sure all the files are where they should be!
Working Solution
Just do
flutter build web, then
flutter deploy.
firebase init tries to generate a generic index.html file for you, and if it did that, then you first have to do flutter build web so that the index.html you need is generated, rather than the generic one, and then again flutter deploy
Please follow the step
npm install -g firebase-tools
If you already have a dist folder, remove it from directory
firebase login
ng build --prod
firebase init
firebase deploy
index.html file has that firebase default information.That's why it is showing that information. Copy and paste index.html from your original angular file and paste it to dist index.html. This fixed my issue.
You should add your files to public directory folder before deploy it into firebase server(your app's index file should be there).
My solution is just waiting a bit.
Then, if it still not working.
let try:
Solution 1: check your index.html inside "build" folder and index.html in your own project. They should be the same, if not, copy code index.html outside "build" folder and paste into index.html inside "build" folder.
solution 2 : delete your .firebase folder. and init it again.
=> firebase init
? What do you want to use as your public directory? build < == NOTE: "build" is my directory
? Configure as a single-page app (rewrite all urls to /index.html)? No <== select NO
? File build/404.html already exists. Overwrite? No <== select NO
? File build/index.html already exists. Overwrite? No <== select NO
After doing these things, I also get that notification of "Welcome Firebase Setting Host Complete" , and I just wait for a while. then reload the website.
Changing the default HTML page name in the public folder to index.html worked for me.
Also, make sure you do not rewrite the index.html when firebase prompts you to in the firebase init step(follow the attached image).

viewing site on http://localhost instead of file://, using node.js

I am learning to use node.js.
The site looks fine when run from file:///C:/.../myfolder/index.html
I have my jquery and bootstrap files in the directories myfolder/css/ and myfolder/js.
but when I run node index.js and go to localhost:3000, these css and js files cannot be found.
This is what is in my index.html file:
<link href="/css/bootstrap.min.css" rel="stylesheet">
<script src="/js/bootstrap.min.js"></script>
<script src="/js/jquery.js"></script>
<script src="/socket.io/socket.io.js"></script>
Is there some folder in nodejs that I'm supposed to store these files? Or do I have to put some code in index.js that imports all the css and js files?
You can simply follow the quick start instructions for Express.js here:
https://www.npmjs.org/package/express
Then browse to http://localhost:3000 to test
You can use the Atom text editor or Brackets and place your files under the public folder and reference them.
http://atom.io
http://brackets.io
By default Express uses a template engine called Jade. You can look here to work with that:
http://jade-lang.com/
Using HTML in Express instead of Jade
Node.js + Express without using Jade
Good luck!
Your localhost begins in a specific directory on you machine. If you use Xampp, you must put all your server files in C:\xampp\htdocs\ in order to acces these via your localhost URL. Some other servers use a folder called 'www'.
Find your server root path en put your files there. Or create a symlink from your server root to your files.
Did you require the path module?
var path = require('path');
It's best to create a public directory to store your files in.
public/index.html
public/css/style.css
public/js/scripts.js
The reason that you couldn't get access to localhost:3000/folder/file is that localhost:port is just a virtual port. There is no such directory called localhost:3000/css/ or localhost:3000/js.
To fix this, you need to use express module to configure the root directory from which to serve static assets.
Basically, you need to add the following code:
var express=require('express');
var app=express();
var path=require('path');
app.use(express.static(path.join(__dirname,'public')));
and your static files directory will be currentWorkingDirectory/public/, which contains all of your assets.
In your code, to link any source file,
href='/fileName.extention'
Here is the documentation link express-static-files
