<script> tags in templates are not added to the DOM, they are just stripped from the template. You need to use other means to add the script. For example require()

After I build my angular app, I have to perform one last manual step to get my program to run: The platform it runs on has a requirement that its javascript file is in the <head> of the html file that is running. Their .js is on a CDN. So basically, post-build, I have to open up index.html and add the following:
<script src="https://cdn.fragilecorp.com/lib/js/platform.js" type="text/javascript"></script>
Is there a way I can accomplish this automatically using angular configs or a different way?
Yes, in .angular-cli.json (.angular.json in older versions), I believe you can add what's inside of src to the scripts array.

How to include external JS file to angular5?
i can't really get my js libraries to work , some time ago i decided to have a separate js file for every library i use (so i have a jquery.js file and a bootstrap.js file included in my layout) ,everything was working just fine until i had to add jquery-ui to this chaos , and got this error
Uncaught TypeError: $(...).slider is not a function
until i loaded ,jquery and jquery-ui in the same file .The problem is i dont want to include jquery ui everywhere i include jquery , beacuse i only use it in 2 pages. Below i will put my code :
jquery-ui.slider.js:
require('jquery-ui/ui/widgets/slider');
require('./components/carFilter.js');
app.js:
window.$ = window.jQuery = require('jquery');
require('./bootstrap');
webpack.mix.js:
mix.js('resources/assets/js/app.js', 'public/js')
mix.js('resources/assets/js/jquery-ui.slider.js', 'public/js');
I am using the following npm modules :
bootstrap-sass
jquery
jquery-ui
I ended up by just creating a file where i require jquery,bootstrap.js and then i require this file in a specific file for the two pages...
Below its the code:
app.js
window.$ = window.jQuery = require('jquery');
require('./bootstrap');
page.js
require('./app.js')
require('jquery-ui/ui/widgets/slider');
It seams that now it is working ,even if now i have to include a js file in all the views...Question its still open , i hope somone have a beter idea .
I think laravel-mix only serves the purpose when you have small sites with pages that all include the same app.js & app.css files.
When you have complex portal with multiple pages that have different set of frontend "plugins" you have to split your entries & generate a table of dependencies automatically.
After a lot of time searching I've come to the conclusion that the best approach would be switch to webpack-encore from Symfony.
You can read more about it's capabilities here Webpack Encore Official Documentation.
Now the question is how to embed it to Laravel? It's quite easy, I've just reverse engineered the Symfony's PHP bundle for that and here is the result:
https://github.com/ntpages/laravel-encore
Now you just have to include you're dependency in the page entry and it's all handled automatically.
I think you should load jquery-ui when a condition is met, like:
if (window.loadJQueryUI) {
require('jquery-ui');
}
And you need to initialize loadJQueryUI for the two pages, like this:
<script type="text/javascript">
window.loadJQueryUI = true;
</script>
I am new with Angular and Angular 2, and I would like to use the following external lib in my project:
http://angularjs.jqueryrain.com/draw-polygons-image-angularjs-canvas/
To use this lib, I have put the following line in my index.html file before angular:
<script src="./lib/angular-canvas-area-draw.js"></script>
But I have the following error:
Uncaught ReferenceError: angular is not defined
at angular-canvas-area-draw.js:3
at angular-canvas-area-draw.js:234
How should i resolve this problem?
Assuming by your tags, you are trying to use an AngularJs plugin inside an Angular application, that won't work (Or at least it would be pretty hard to get it running by using the upgrade adapter and some zonejs hacking). Try to find the plugin for Angular instead of AngularJs.
But if your tags are misleading and you're using AngularJs than make sure AngularJs in included before the plugin.
<script type="text/javascript" src="./lib/angular.min.js"></script>
<script src="./lib/angular-canvas-area-draw.js"></script>
Move your dependencie into .angular-cli.json file under scripts like this
"scripts": [
....,
"./lib/angular-canvas-area-draw.js"
],
from the latest angulae cli you have to add all external files(css and js) under the script and style tag in the angular-cli.json file
I have created a new Rails 4 project and I am trying to load an external JavaScript file in my HTML file. I have placed the JavaScript file in the /assets/javascripts directory and included the file in my HTML file.
My HTML file:
<html>
<body>
<script src="/assets/hello.js"></script>
</body>
</html>
My JavaScript file:
document.write("test");
I do not see any errors in my web browser console when loading the website. I am pretty sure I put the JavaScript file in to correct directory but the file will not run. Does Rails require something for external JavaScript files to work properly?
I have also tried defining a method in the JavaScript file and calling it within a <script> tag but I get a "Uncaught ReferenceError: methodname is not defined".
You probably need to list 'assets/hello.js' in application.js. The Rails asset pipeline compiles all JavaScript into application.js based on the filepaths that it finds listed there.

So I figured out why Rails wasn't loading my JavaScript file. When I created the Rails project, it included .coffee scripts which can be used instead of JavaScript. For some reason by default, the .coffee script was being run instead of the JavaScript file that I created. After deleting the .coffee script, my JavaScript loads as expected.
In the Jangaroo tutorial using Maven it states"include a Jangaroo application script generated by the Maven build process". This should be created in src/main/webapp/index.html, it isn't. Can anyone explain this, or what in the pox.xml is missing?
Thanks
The misunderstanding here is that actually, the Jangaroo application script is generated, not the index.html file.
The idea is that your index.html usually contains custom HTML, e.g. loading your CSS or setting up some context. The only Jangaroo-specific things your HTML code has to do is load the generated joo/jangaroo-application.js script and run the application's main class, using its fully-qualified name (in this example, HelloWorld is in the top-level package):
<script type="text/javascript"
src="joo/jangaroo-application.js"></script>
<script type="text/javascript">
joo.classLoader.run("HelloWorld");
</script>
