Angular is not defined Gulp.js - javascript

I still have this error Angular is not defined. Im 99.9999% Sure its something to do with the paths not being confugred properly, but im out of clue. I cant fix it! This is my folder structure as of now:
bower_components/
node_modules/
app/
components/
home/
controller/
homeCtrl.js
css/
home.css
home.html
shared/
css/
directives/
filters/
directives/
sass/
services/
assets/
audio/
debug/
dist/
app.min.js
vendor.min.js
lib/
etc...
gulp/
paths.js
gulpfile.js
index.html
etc....
It for some reason says angular is not defined.

Help would be greatly appreciated here! Btw im working it on Cloud9IDE So if we could fix it there, it would be quick and fantastic! https://ide.c9.io/amanuel2/ng-fourm

The reason was that i mispelled javascript:
<script type="text/javscript" src="assets/dist/vendor.min.js"></script>
It was preety hard to find because, something that simple can completely throw you off!

Can't load stylesheet, "MIME-type not supported"

I'm using gulp for a website using Bootstrap that I'm trying to set up. I'm able to successfully run gulp from the node.js command prompt:
gulp running from command line
But no stylesheets are applied to the webpage that loads:

I've already checked this post: Stylesheet not loaded because of MIME-type and can't find the answer to my problem in it.

Also, I'm trying to follow https://www.youtube.com/watch?v=hnCmSXCZEpU&t=766s for getting bootstrap started and I know that a lot of people from the tutorial have had trouble with this part. Maybe this post can help them too..
EDIT 1
I tried using gulp serve, nothing changed. Here's a link to the edited gulpfile.js

I run the app using Spring-boot, but when I use it in Chrome I get an "Uncaught Syntax Error: Unexpected identifier". The JavaScript that causes the issue is:
import log from './utils/log';
import formatTime from './utils/format-time';
import pluginDefaultOptions from './defaults';
import window from 'global/window';
import videojs from 'video.js';
import WaveSurfer from 'wavesurfer.js';
I tried inserting type="module" into html as suggested in this Q&A, then Chrome stops complaining about the first import-from and gets an error at the "import window from 'global/window' line

how are you compiling this? Based on your syntax and the names of your compiled modules, I'm assuming you're using either Webpack, which means you're likely using Typescript (unless you meant to tag as AngularJS instead). In any case, ES6 import statements are the same, and the syntax you're using is for default exports only.
import can only be used in ES6 JS if type="module" is on the script tag.
So, unless you're setting default exports and relying on them, the syntax for importing explicit exports is:
import { exportedProperty1 } from 'module-name'
import { exportedThing1, exportedThing2 } from 'module-name'
import defaultExport from 'module-name'
import * as Name from 'module-name'
...where 'module-name' is a relative path to the file.
This syntax does not require type="module":
let myThing = import('module-name')
your issue with window from global/window is going to be specific to your bundler, your platform, your files, and your polyfills.
All the packages that contained es6 JavaScript had to be compiled individually using webpack, then changes had to be made to the "overrides" section of bower.json for the big project to include dist directories and generated min.js files of the compiled projects in order for gulp to inject them. E.g.
"overrides" {
"videojs-record": {
"main": [
"dist/videojs.record.min.js"
]
}
}

Not able to correctly inject files using gulp

My app structure is following:
-gulp
-src
-app
-assets
-css
I want to insert files from "css" folder in index.html which is in "src" folder.
use the below code and set the path accurately.
var inject = require('gulp-inject');
var $ = require('gulp-load-plugins')({ lazy: true });
gulp.task('inject', function () {
var injectStyles = gulp.src(['css/*.css'], { read: false } );
return gulp.src( '/src/index.html')
.pipe($.inject(injectStyles, { relative: true }))
.pipe(gulp.dest('/src'));
});
specially you need to enter styles comment tag in your html file as below:
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<!-- inject:css -->
<!-- endinject -->
</head>

VegasJS are not working with bower

I am trying to use VegasJS as a slider, and Bower o manage my packages, but I am not able to run the vegas using bower, and Vegas aren't working at all, I tried to use without bower too, but was not successfully. It only occurs in my localserver, because I rewrite the exact same code in Codepen, and it works perfectly.
I'm using Gulp too, don't know if it will make some difference.
My HTML code:
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">
<title>Page Title</title>
<!-- CSS -->
<link rel="stylesheet" href="../bower_components/normalize-css/normalize.css">

<script type="text/javascript" src="./js/main.js"></script>
</head>
<body>

</body>
The CSS code:
* {
margin: 0;
padding: 0;
box-sizing: border-box; }
header {
height: 100vh;
background-color: crimson; }
The JavaScript code:
$("header").vegas({

{ src: "https://unsplash.it/1000x1000?image=500" },

{ src: "https://unsplash.it/1000x1000?image=261" }
]
});
Gulpfile.js:
var gulp = require('gulp');
var sass = require('gulp-sass');
var autoprefixer = require('gulp-autoprefixer');
var browserSync = require('browser-sync').create();
gulp.task('sass', function() {
return gulp.src('./public/sass/*.scss')
.pipe(sass.sync().on('error', sass.logError))
.pipe(sass())
.pipe(gulp.dest('./public/css'))
.pipe(browserSync.stream());
});
gulp.task('browser-sync', ['sass'], function() {
browserSync.init({
server: {
baseDir: "public",
routes: {
"/bower_components": "bower_components"
}
}
});
gulp.watch('./public/sass/**/*.scss', ['sass']);
gulp.watch('./public/*.html').on('change', browserSync.reload);
gulp.watch('./public/js/*.js').on('change', browserSync.reload);
});
gulp.task('autoprefixer', function() {
gulp.src('./public/css/style.css')
.pipe(autoprefixer({
"browserslist": [
"Chrome",
"Firefox",
"Explorer",
"Edge",
"iOS",
"Opera",
"Safari",
"ExplorerMobile",
"last 3 versions",
"> 1%"
],
cascade: false
}))
.pipe(gulp.dest('./public/css'))
});
gulp.task('watch', function() {
gulp.watch('./public/css/*.css', ['autoprefixer']);
});
gulp.task('default', ['sass', 'browser-sync', 'autoprefixer', 'watch']);
Everything seems to be working very well, with exception of Vegas, I don't know why in my localserver it aren't working.
In this case, I tested the Owl Carousel, and its working perfectly well, the only problem here, are the Vegas. I almost certainly the problem are on css link.
I tested in WebStorm and Atom IDE by the way.
Thanks for all the help, but I fixed it, what happens was, I commited the mistake of add the initialization without document ready property, the right way:
$(document).ready(function(){
$("header").vegas({
slides: [
{ src: "https://unsplash.it/1000x1000?image=421" },
{ src: "https://unsplash.it/1000x1000?image=500" },
{ src: "https://unsplash.it/1000x1000?image=425" },
{ src: "https://unsplash.it/1000x1000?image=261" }
]
});
});

My setup is express server and system JS.
server.js
var express = require('express');
var bodyParser = require('body-parser')
var fs = require("fs");
// initialize express
var app = express();
// declare build and node_module paths
app.use(express.static("./build"));
app.use(express.static("./node_modules/"));
// parse request body
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
var body;
// route to send json data from angular 2
app.post('/export', function(req, res){
body = req.body;
res.json("Got the data!");
fs.writeFile('parameters.json', JSON.stringify({body}, null, 4), function (err) {
if (err) return console.log(err);
console.log('Data json file created!');
});
});
// start server
app.listen(process.env.PORT || "3001", function(){
console.log("Express server running on localhost:3001");
});
If its the free heroku tier its probably because its sleeping when you request it?
You can minify and concatenate your js files to decrease load times.
Here is a guide on how to do that with gulp tasks:
