JS Bin VS Judge0 API

JS Bin is one of the useful JavaScript debugging tools designed for developers working with HTML, CSS, and JavaScript. It gives them the opportunity to test and debug their code snippets in a real-world setting. The fact that this tool is open-source is fantastic.

If I paste both in jsbin.com, the both show all content on 1 line.

A running example in https://jsbin.com/ might be easier to help with

JSBin : Front end playground, Output is not framed, so it allows you to share those snippets that will break inside an iframe.

> What if you want introduce some diagramming or Latex rendering in your blog ?

Then you are starting to step beyond what I was referring to as “a simple blog” (text, formatting, maybe some pictures or SVG).

Though there are options that don't require a CI/CD pipeline. Depending on what Latext you need MathJax may do the trick (just include the JS in your standard page header, and drop the Latex code straight in inline where needed as per their standard example: https://jsbin.com/?html,output. There are similar charting options like mermaid too. I don't know of inline charting options off the top of my head but I expect several exist.

Post your code on codesandbox.io or jsitor.com or jsbin.com or jsfiddle.net or whatever other site you prefer. Then we can look at it and see what is wrong. Otherwise, it's like showing us a picture of your cat and asking whether we think you might be allergic to it.

Important note: do not perform tests with WeakRefs in dev tools. Your objects won't be GCed in it due to DevTools specific behaviour. Instead, use jsbin, codesandbox, runkit or perform tests in Node.js. Localhost is okay when you open files using http:// protocol, as file:// also has specific behaviour.

There are services like Judge0 which you can use to execute the code in a sandbox. Just send a code as a string and get a result back. You can either use their cloud offering or deploy the container yourself (it is opensource). https://github.com/judge0/judge0

I'm trying to run a local version of the Judge0 compiler, but I can't seem to access it.

I have a front-end app which exposes a code editor where the user can provide some code and it will be compiled and executed using judge0 (so not on my server). I would like to be able to save the code created by a user, but I'm not sure of the best route to do this. My initial thought was to save the code as a string in a database, passing through my back-end which could potentially have some sanitizing methods to try and minimize any danger with this. However, I'm not sure how practical/feasible it is to try and sanitize code - has anyone attempted to do this previously or have experience in this domain?

You can deploy Judge0 Extra CE on your own servers for free. Here are the release notes that include the deployment procedure.

https://judge0.com/ to run the code, you can can host it on your server for free or use their api.

A signal gets called which gets sent over Django Channels (but you can probably use an mq or something for this) which notifies a microservice that is responsible for sending and receiving submissions to an instance of https://judge0.com/
