hi I'm completely new to the MERN stack and am completely comfortable with html and CSS. however when I look at MERN tutorials online I see no html. is there a way I can still write up my websites I want to create using html and CSS then dealing with back end using MERN?
The "R" in MERN stands for React, which means writing JavaScript (or TypeScript) using the React ecosystem, usually including JSX (which is an XML/HTML-like syntax for representing UI) React is what you'd use instead of writing HTML and vanilla JS or jQuery. Anything you can do with React, you can do with plain HTML, CSS, and JS, though it might take a lot more work. If you use Mongo, Express, and Node, without React, that would work perfectly fine, but it wouldn't be the MERN stack.
Yes, you can use your normal HTML CSS & JAVASCRIPT for the frontend.
But before that lets understand what is MERN.
MERN --> stands from MongoDB , Express , React , Node js
Let's breakdown more:-
Mongo DB --> This is a database
Express --> This is a package to make our server (just like http package)
React --> This is a frontend framework for creating React apps.
Node js-->This is the environment for running your javascript code (Basically your javascript code runs on a browser environment but when you deploy your javascript codes on the server for making the backend there is no browser that's why we use node to provide a javascript environment to run the javascript files )
Collectively we make a whole website using all these.
But as you said can we use HTML , Yes you can use HTML to make your frontend only but you can't use HTML to program your backend because it's not possible.
In MERN you can replace "R" With (HTML , CSS , JAVASCRIPT) But MEN will be going to remain the same because these are used only to make your backend.
And combining it all We call FullStack web development.
I hope you will get it all. :)

I have a pug template index.pug for my project. I have also made navbar.pug, footer.pug, sidenav.pug. These files are included in the index.pug.
For server side I am using node.js, express.js and socket.io. Now I want to update only the navbar.pug file according to server response. But when I tried to do that I found some solution. But all of them refresh the full index page.
Is there any method that can help to update an specific portion of the webpage(in PUG) without refreshing the whole page?
Thanks in advance...
No, pug is a server-side only HTML processor. As such there is no way to do what you describe here - to get pug to process more means another round trip to the server to re-render the page.
Although technically you could do this with plain JavaScript, you should look into a client-side library like jquery, React, Angular, or Vue to do what you want. A lot of us use pug in combination with those toolsets to build modern web apps, but with those frameworks pug becomes a quicker way to write HTML and is no longer a server-side pre-processor.
I have ~2,000 lines of HTML code that I can retrieve from my Java server. This HTML code also has angular directives inside of it, such as ngIf* and (click) and [ngClass]. When I try to display that HTML in my client with such methods as the below:
<div [innerHTML]="htmlData"></div>
<div innerHTML="{{ htmlData }}"></div>
I see all of the HTML elements displayed correctly, but none of the angular directives are working (such as some of the HTML should be hidden with the *ngIf but they aren't... and none of the (click) events work. What can I do to fix this?
I need this functionality because I am delivering my code as a JAR file to various users to run on their local machines, and I want to serve the HTML code from some Amazon's S3 so I can update it whenever I want to give their website an update.
And I tried looking at the below answers, but those dealt with pure HTML from the server, and didn't have any angular directives.
Inserting HTML from server into DOM with angular2 (general DOM manipulation in Angular2)
Angular HTML binding
Unfortunately it's not possible. InnterHTML will put HTML code there - not angular. Angular code should be compiled ahead of time - a process where all the directives and html magic is replaced with simple JS.
You can transform you angular code to plain html by server side rendering with node js.
You can read more about server side rendering here: https://angular.io/guide/universal
But just as well you can use JAVA and with any popular templating framework for JAVA servers if you'll send your parameters on the http request.
I would like to to use React with Django non Single Page App way - Django will take care of routing, and rendering HTML templates and serving data.
React should be used just on some specific components inside HTML page for eg. (dropdowns, autocomplete, modals), ideally being able to just drop for eg. div element with a class inside HTML and pass props for React component.
What’s the best - maintainable, scalable solution to go about this ?
See django-jsx package and also server side rendering paper. I'm not a frontend specialist but when I've faced such problem, my friends offered me to google isomorphic app with django and react.
I found this add React to an HTML page in one minute page/example to be absolutely painless in rendering a React component inside of a Django template!
This probably isn't what you want to do, given that React has a pretty robust ecosystem around it for building performant single page applications (SPA's). You should be able to decouple your React site from your Django app. Then you'd be able to throw up your React app on a performant CDN, rather than having your Django server hosting every visitor.
But if you insist, the most straightforward way to proceed would probably be to create an index.js & index.html at each Django route. In other words, make a separate "React app" at each route, which Django will serve as users go to each endpoint. I've seen this done before. It's laggy and inefficient (relative to an SPA), but can be done.
If you really intend to go so far as to write raw HTML/CSS/JS and just use React for bits and pieces in between, you'll probably be looking to invoke ReactDOM.render using a variety of second arguments (called container) rather than the standard React-y way of doing a single ReactDOM.render(<App />, document.getElementById('root')); for the whole app to inject into a barebones HTML template.
I notice you tagged your question with server side rendering. If that is a hard requirement for you for some reason, I'd look into using next.js, a Node framework optimized for exactly that.
I am working among a team on a large web projet.
These are the technologies involved:
Meteor: Full-stack JavaScript framework
MongoDB: DBMS
React: included in Meteor as the following 2 main packages react v15.6.1 and react-router-dom v4.1.2
My question concerns the front-end part of the website and its integration with already developed early versions. The specifications of the front-end section were translated to hand drawn wireframes first, then digital ones using Balsamiq.
While developing the first versions of the website, I used React and now I am in love with it (and kind of stuck with it too to be honest :D).
I am not normally in charge of the front-end section of the project, but I will be responsible or integrating it with my already done work.
Knowing that the digital wireframes will be coded in HTML, CSS and JavaScript, my question is: Is there a way of integrating/translating/rewriting an HTML, CSS and JavaScript template to fit React?
My question basically boils down to; how to integrate an HTML, CSS and JS template into a React project?
If there is no way to do so, what would be the best approach: rewrite my code, or the template should be written in React?
What I usually do, is copy the HTML tags/elements from the file into React's return(){} and then add React components and modify some css to make it look like you want it to. Remember, React's return(){} is basically rendering HTML plus your own React components and Javascript to make them work the way you want them to.
However, if you just want to display a page, you can always
import React, { Component, PropTypes } from 'react';
static contextTypes = {
router: PropTypes.object
}
this.context.router.push('/page');
and set the path to direct to the HTML page in your route.js file.
I have to make a html page with css and javascript that I have to enter a url in a form. With this url, I have to get some information from the html of the page with a Python 3.2 Script.
I start learning Python some days ago and I have some question:
I need CherryPy/Django to do that? (I'm asking because I executed a script to get the entire html without using CherryPy/Django and it works - no interaction with browser)
CherryPy examples have the html built in the python code. I must write the html in the python script or can I have an html page that call the script with Ajax (or anything else)?
If I can use Ajax, is XmlHttpRequest a good choice?
Thank you! :D
No, you don't need a web framework, but in general it's a good idea. Django seems like brutal overkill for this. CherryPy or Pyramid or some micro framework seems better.
You can have an HTML page that calls the CherryPy server, but since this page obviously is a part of the system/service you are building, serving it from the server makes more sense.
Sure, why not.
