I have a Flask application I have built locally and have hit the wall as to having javascript with npm packages being able to be used because I am consuming REST APIs and using jQuery per my application. I followed the advice here and have Webpack working.
I ran the command npm run watch
webpack --progress -d --config webpack.config.js --watch
0% compiling
Webpack is watching the files…
Version: webpack 2.1.0-beta.21
Time: 4836ms
Asset Size Chunks Chunk Names
bundle.js 5.97 MB 0 [emitted] main
[366] ./js/index.js 15.3 kB {0} [built]
+ 366 hidden modules
So now I have webpack working with my index.js file and I have the Flask app being served using gunicorn and Docker on 5000.
Everything is working, but my JS is still unresponsive in my Flask application.
Does anyone know what I do to have my index.js file to work per this Flask app with these components I have, or what I am doing incorrectly here?

Make sure that your Flask project structure contains static folder as per Flask documentation.
According to the relative bundle.js file path in index.html template, your static directory should contain js directory. Make sure you have it there after using webpack and it contains your bundle.js, index.js and the rest of files mentioned in your template.

I am trying to call the login function which goes to the login page in login app on main page url. Also I want to make the login function works across different apps. Therefore, I am not able to call the function here (in the example code provided). Is there any way I can call the login function here (in the example code provided). So, I don't have to create login page again.
If your base.html say is in an app called pages, and the template path is pages/templates/pages/base.html you can do in all apps
{% extends 'pages/base.html' %}

I'm new to Django. I'm having problem including a sub-template in a main template. The directory structure of my project is attached in the snapshot. I removed the default views.py and created my own folder named "views" and put my views in it. Here is what I've done:
1. app/views/__init__.py
from .home import *
2. app/views/home.py
from django.shortcuts import render
def index(request):
return render(request, 'home.html')
3. app/templates/home.html

The problem is include is not adding content from the sub-views.
I understand it could be a path problem but I tried various options like:
{% include "includes.header_logo.html" %}
{% include includes.header_logo.html %}
{% include "includes/header_logo.html" %}
{% include "templates.includes.header_logo.html" %}
{% include "app.templates.includes.header_logo.html" %}
etc.
You have to use directory slashes (/), not dots (.)
For example:
{% include "includes.footer.html" %}
becomes this:
{% include "includes/footer.html" %}
As suggested by Leistungsabfall, "includes/footer.html" works. The header was not working because it had:
This line must be crashing and because of which header was not working.
Simply add template folder with slash .... like
{% include "blog/footer.html" %}
