I was trying to crop videos with cropper.js, but from what I understand that it is impossible and only works for photos. I've looked everywhere for resources to do such, but I couldn't find anything. If you don't know what I am talking about I would like something like this https://codesandbox.io/s/react-easy-crop-for-videos-lfhme but uses JavaScript instead of React. The reason I don't want to switch to a frontend framework is because I am using Django for my backend, and am not comfortable with switching to APIs, and using React or Vue, since I am really far into my project. I also want to avoid using a hybrid architecture if possible. If anyone knows of any libraries or repositories I can check out that might help me that would be much appreciated.

Just in case I can use videos in cropper.js here is my source code.

I am new to programming and one thing I am very confused about, my boss has told me to create a rest API about an app which I have completed all the signups, login, and other parts. But now I have to create a frontend but all the tutorials on the internet are about create rest API of Django to react or some other frontend framework, is their any tutorial on YouTube about connecting to a html CSS JavaScript on frontend to Rest API. thanks.

I am trying to have my frontend server pull an http request from my backend server, but am getting the following error in my browser console:

I have a container being used to hold a registration form. I tried adding position: relative then using top: combined with a negative integer to move the image, but what happens instead is that the entire container is being moved, rather than the background image. I am using bootstrap as a frontend framework.

I know the standard way is to use Express, but i was wondering how i could achieve this without having to use it. I already know how to serve html files using http/https in a common website (without a frontend framework) through nodejs, but when i tried to do the same with index.html from React app, it wouldn't work. I think it's important to mention that i am using react-router. I searched a lot about this but every tutorial would use Express, so i couldn't find help in google.

Here's how i would do with plain html:

I am using React.js as Frontend framework,

I have an icon from antd, and I want to put it in the 'alt' prop of an image tag, so in case that the url I pass there will be null - it will go to put the icon there.

I tried using 'alt' but it only accepts string. is it possible to put there an icon? (like one from antd?)

to emphasize - I want to add it as - }

as in in an actual icon and NOT AS A URL.

I am writing code that uses data binding to change the innerHTML of an span to the input of the user, but I can't get it to work. What it should do is show the input on the right side of the input field on both the input fields, but it doesn't. Can someone please help me out.

We are a small company, using emberjs as the main frontend framework for our projects. The frontend architect sticks to it like liquid glue sticks to paper, because he doesn't know any other frameworks. The main reason that is forced is the slogan: 'convention over configuration'. And there are reasons like emberjs is faster in larger scale applications. Anyone can reason pro-contra for emberjs, angular, react etc.. (hopefully someone who knows all of them, at least emberjs, and another)? We are having meeting sessions about this, where junior frontend devs try to convince the architect about the other frameworks. In my opinion this should not be a technical issue, all of the frameworks are capable of developing 'larger scale' applications. The real reason should be the recruiting, we would find react/angular devs more easily. Thanks

Right now I'm building an application where I use Symfony 5.3 as a full stack framework. So I use twig for my views and vanilla javascript. At first this wasn't a big problem but I had to build a few multi step forms and it's starting to be really annoying. Although I'm new to frontend frameworks I want to give ReactJS a try. After some searching I found Symfony's Encore bundle. The only problem that I have is that the hosting server does NOT have NodeJS installed.

Is it possible to use React (with Encore) without node running?
