Add Node.js example using EdgeDB Auth

[scotttrinh]

To accompany the EdgeDB Auth Guide, this is an example of a complete stock Node.js HTTP server that exercises the EdgeDB Auth extension.

TODO in future effort:

• Show protecting a route by looking for the cookie
• Show making an authenticated (access policy) query using the auth token
• Add a simple-as-possible HTML interface

Suggested a small fix in the package.json.

When I try edgedb project init, I'm getting edgedb error: cannot find package matching 5.0.. Should the version in edgedb.toml be 5.0 or 4.0?

It might be nice to add a readme with some basic stuff. If we just included a few steps on how to get the project running and a link to the guide, that could be enough for starters. It might also be nice to tell how to get the Nix environment up and running but also mention that it is optional so people know they can run the app without that.

Interesting. I don't think I actually made this edgedb.toml explicitly. I think it should be like 4.x or something like that. Will fix!

Yeah, that makes sense to me.

Yeah, I think we can get this with a "Requirements" section that shows how to use the Nix flake, or if you do not have Nix installed, what the requirements are. Should make it clear that the Nix flake manages the environment dependencies for you.
