title: Can I run a web server in a GitHub Codespace?
body: <p>Part of my development process involves using Mocha and Chai tests.  I have a page in my test folder that loads all the code and tests, and I can start up a local node script that runs a simple local server, visit that page on <code>http://localhost:8080/blahblahblah.html</code>, and see the test results.</p>
  <p>GitHub recently announced Codespaces and I signed up for the beta.  If I start developing in a Codespace, I know there's a terminal there.  If I run my testing server in that Codespace, how would I see the test results?  Is it even possible to connect to the server in the container from outside?  What would replace the URL I show above?</p>
