It handles them just like running a Linux terminal with VS Code. Because you're running a Linux terminal with VS Code :)
If your question is how do you do web applications, as long as what your working on can serve requests at 0.0.0.0, the Coder.com extension will create an internal URL for your account where you can access the site while the container is active (very similar to Cloud 9, except that Coder chooses the internal URL for you instead of being based solely on your username and project name).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
