Modularization of html content in Electron app - html

I know a typical practice to build an Electron app is to follow SPA (Single Page App). I still would like to split my html content into separate files for easy maintenance. There is still the main index.html file which is to be loaded on startup.
My question is: is there a protocol for inserting a part of html content from a different files? For eg. in Django, there is a include and extend tags where you can insert an entire html file into the body of another parent html file or retain certain features from another html file.

There's no way to do this directly. Django is a server-side framework, so you can assemble your HTML on the server, and the completed HTML is sent to the client/browser. With Electron, you're basically running Chromium with Node.js APIs added, loading your HTML from the filesystem, so there's no server to do any HTML assembly in.
However, if you just want to break up your HTML into pieces for easier maintenance, but you're not doing any of your include/extend dynamically, theoretically, you could use some kind of templating system or a static site generator to combine your HTML files statically at build time.
Here's an list of some JS templating engines: https://expressjs.com/en/resources/template-engines.html

Isn't the html of the form Django displays on the screen?

Django shows you forms when you do basic coding, right?
Where is the html of the automatically generated form in windows?
So instead of looking for a template folder, once the developer writes the url or views code, he finds the location of the skeleton-only html that Django shows.
In my opinion, it looks like it's built somewhere like an "anaconda/envs" contains a separate virtual environment, but I can't find it.
it's maybe path?
It's well documented:
https://docs.djangoproject.com/en/2.2/ref/forms/renderers/
It loads templates first from the built-in form templates directory in
django/forms/templates
unless you have 3rd party libraries included that override these templates.
However, a quick check in https://github.com/django/django/tree/master/django/forms/templates/django/forms/ shows that this directory is empty.
tl;dr
Django does not render any forms from scratch (unless it's the Admin which of course creates its whole UI automatically). It just enables you to quickly create a template that can render your form but you will still have to provide a basic template (aka HTML markup with dynamic parts) yourself.

How to emulate the behavior of master page in Net.Core and VS Code

When building an MVC project, there's a shared folder automatically provided in which I have Layout.cshtml page that's used like the holder or master page (as it was called in Web Forms). So, all the banners, navbars, footers etc. go in there, while the acutal pages being developed refer to it in the source code and got pasted together upon rendition. This far I'm following.
Now, I have a set up and AspNet website using Yeoman and the only thing I have is wwwroot directory in which I put the file start.html. (It's the same as index.html - I just wanted to try out if I have full control over default files.)
I'm unsure how to proceed. I.e. I'd like the links on the start.html to point to files like uno.html, duo.html etc. and read those into a designated part of the landing page (i.e. start.html).
Is it doable without using the magic of templates? I want to have full control over the rendition process.
There's no point googling it, I noticed, because anything I've got the last two hours leads to how to create master page not to how to emulate master page.
Well, the static files middleware is just for that: static files.
You roughly have two options:
Do everything client sided, i.e. rather than having normal links use javascript/ajax calls and embed the content of the static file in your start.html using javascript.
It should work, but has several down-sites like it requires javascript to work (not a big issue these days, except for the paranoids who use no-script browser extensions) and that web crawler still may have issues properly indexing ajax heavy web pages
Wait until ASP.NET Core 1.2 (scheduled for Q1-Q2 2017), which will add Razor Pages. Pages rendered with Razor template engine, but without the need of a controller.
1.2
WebSockets
SignalR
Razor Pages (Views without MVC controllers)
Web API security
If you don't wanna wait, try RazorLight, which is 3rd party open source library for rendering Razor views.
But all except the first one require some "magic template engine".
You could of course write an server-sided includes (SSI) middleware which would be based on UseStaticFiles middleware and parse the file and include the html files server sided before returning it. There is nothing out of the box for it as far as I know.

What is the best way to include an external html file into another html file?

When I have one basis html file in which I want to embed a few external html files as sort of a portfolio page, what is the best way to embed those external html files? I now use iframe, but I've read that is not the preferred way? What other options are there and which one is the best?
Most modern websites implement a server-side framework such as php or asp.net that can assemble the final HTML for each page and output it together
The only issue with iFrame is that it causes additional round-trips to the server, as the client has to load each frame individually, but if you don't have access to any server-side scripting then any other solution will do the same thing

Can I still use `.cshtml` files in a hybrid mobile project?

All the resources use only HTML, but stuff like Cordova and Ionic work on the client, with HTML pages (and JavaScript and CSS of course), and once MVC has served a page, that page is HTML, so the hybrid tooling should be able to use it.
The only problem is that once it's served, it lacks the .html extension, but maybe I can figure a way to add this.
The reason I'd like to stick to .cshtml for my layout is that I can scaffold views from my sever-side view models, and this adds quite a lot of value for me.
If the question is: can you have .cshtml files on your mobile device, the answer is no. .cshtml file is processed on server by the Razor view machine, so plain HTML can be generated. Obviously you don't have MVC, Razor and such on your hybrid ionic app.
You can however work around it by taking your angular templates to be generated on your server by MVC. So, when you setup your templateUrl somewhere, instead of taking the relative path to your local template .html file, you can point to the controller on your server, giving the full path, with http:// and so. The controller will then generate your template for you and return as plain HTML.
Bear in mind, that angular will cache this, so it will be loaded only once.

Render plain html in Master Page web form

I'm writing a web application in ASP.NET Web Forms. I have a Master Page and I will include some knockout templates inside. For some structural reasons I don't want to add that templates inside the Master Page code directly, so they will be in differents files.
Structure.
Masterpage.master
template1.template.html
template2.template.html
template3.template.html
I have done the same thing in MVC, but it was easy just rendering partials.
Is there anyway to do the same thing with a helper class or something?
I need that code in every page that includes that Master Page.
Create a user control (.ascx) file and move the required markup out of your HTML files and into the ASCX files. Then register the controls (at the page or web.config level) and use them in your master page.
