Is Code Sandbox a legit and safe editor?
It's legitimate. In fact, many projects host their own examples on CodeSandbox. If you go to one of the component pages for Material-UI, you'll see above every example there's a pencil icon. Click that, and it will take you to a CodeSandbox that includes the example. For instance, here's the sandbox for the first example on that page I linked: https://codesandbox.io/s/mnvxm That said, it's an online in-browser editor. That's both its up-side and down-side. It's "safe" (not really sure exactly what would be unsafe about it in this context), and it's easier to just get started because they have project templates, but not that much easier. It's easier to share running examples. But at the same time, you're limited to one window in a browser, where in a local editor you can open several files. You also have more control locally. So, it's fine for learning purposes, but you eventually want to start using your own local setup anyway. More on reddit.com

December 8, 2020Using CodeSandBox instead of local for projects
What do you mean “using local”? I think you’ve covered the big pros and cons of using something like CodeSandBox. It really depends on what use case you have. I try to do things in a simple way using less dependencies, so I’d always prefer just using syntax highlighting rather than relying on an online service. More on reddit.com

February 13, 2024CodeSandbox - An online React editor with a focus on easy sharing and reusability
Hey Reddit!
This is a project I’ve been working on for the past few months. With CodeSandbox I want to focus on a feature of React that, in my opinion, could be exploited much more, which is reusability. With CodeSandbox you can easily build and share a React project with anyone by just sharing the url, others can then fork it to make changes or download it (which includes the default create-react-app template).
The next thing I’m building for CodeSandbox is the real reusable part: it should be possible to publish any project you have on CodeSandbox to NPM with a single click and let others reuse it as much as they like. An example is that someone makes a button on CodeSandbox and publishes it, others can then use this button inside CodeSandbox or in any project out of CodeSandbox. Publishing is already done, I’m now working on UI so publishing and searching sandboxes becomes easier.
I’d love to hear any feedback or suggestions or problems you might have! I want to make CodeSandbox as friendly as possible.
I also encourage everyone who built something cool to share it here. I will also put some of the sandboxes on the homepage.

r/learnprogramming on Reddit: Is Code Sandbox a legit and safe editor?
December 8, 2020 -
I am a student and I'm currently learning React JS and my friend recommended this Code Sandbox to use it as a simpler and faster alternative to creating the npm apps on my local machine that React JS usually requires. I just want to ask if that site is sketchy or safe and if it has any drawbacks?

Is there any other reason for using local over codesandbox-type online editors, than the fact that it gives local hosting and is with the files locally secured? Thanks in advance.

Pricing model aside (I'm not sure what the pro plan for CSB looks like these days) you're going to have a development environment that is much weaker than a MacBook Pro. That may be significant for you if you're doing ETL on large data sets, or training AI models, or other heavy computational tasks. CSB is probably fine if all you're doing is rendering a web app though. I believe CSB supports Docker now, so you can have a devbox with your full backend services included, but there may still be restrictions depending on if you're free tier vs paid.

r/webdev on Reddit: Self-hosting code demos a la a Codesandbox.io?
February 13, 2024 -
A bunch of these code sandbox sites are pushing more and more to paid accounts and I'm looking for a way out.
How do others handle this? Do you guys self-host a repo and just keep making sections/pages? Is there some project out there that basically lets you self-host a full Codesandbox.io clone? Or do you just shut up and pay?
Also, I'm curious how else other people use sites like this. For my part it's mostly, "Oh I wonder how I could do that..." kind of experimentation, whipping up a demo of a bug or technique to share, stuff like that. I think that's why I'm hesitant to spend too much money on this because I don't use this as a full on core tool.

hey, I just hosted my own domain name through netlify I'm pretty much still learning web dev. I tried for so long to skip HTML and CSS for 10 years and after my javascript class, I realized that was a big mistake and I wasted so much time after I learned about the DOM and how powerful HTML is. My javascript instructor from 2023 fall semester taught us on codesandbox.io ,. I myself would have used notepad++ at that time. The benefit I got from these sites is having a place for my previous work saved online. At that time codesandbox.io was kinda buggy with some of its features so we had the option to use replit after a student who was an adept web programmer recommended it. My background was in Java so I would use an IDE normally but not knowing computer maintenance and failing laptop parts has been my downfall. Anyway javascript was kinda confusing but I made it out of the class with a B+ and was completely happy with that. I would have done much better if I took the beginner web development courses before but I was able to test into Javascript from my previous experience designing my websites. but like you said codesandbox is pushing more into paid memberships. I wonder what the benefit is? I just optimized my laptop and removed all the bloatware I didn't know existed until I took a Comptia A++ class 2024 spring. Since then I've been going through everything I learned in college and incorporating it into my workflows. I'm about to get into optimizing VS code but I wanted to do some research on using replit or codesandbox. I emailed my instructor, and he said he likes codesandbox.io because he can see a preview and the source code as an instructor. I'm just trying to keep my laptop minimal and not have too much software until I have more experience aka holding off getting into using VS code. But I'll check out stackblitz like bunnyfy recommended. Thanks for posting this question. If you have any knowledge you can share 10 months later please comment below.

Made an online code editor, like CodeSandbox. Think VS ...
March 29, 2023 -
Hey guys, I've made an online code editor from scratch. Think CodeSandbox, but watered down a little. It uses xterm.js to give a shell to the user on the frontend, and monaco editor for editing your files, and I generate the folder structure recursively. I've used Zustand for global state management
There's also multi file support, so you can switch between open tabs just like the real thing. I tried to get it as close to VS Code as possible, and there's a bunch of stuff still left to do, but a major chunk of the project is done.
Lemme know what you think!

Can you talk about any interesting challenges you ran into while building this? How is userland code executed? And how do you keep it separate from editor code? Suggestion: Move screenshots to the top of the README. Usually folks casually browsing want to see the end result before diving into the details.
