firebase serve config

[vladiim]

Whilst working through you Web Chat App Javascript tutorial I hit an error when executing firebase serve.

From, firebase-debug.log:
[debug] TypeError: Cannot read property 'public' of undefined at Server.<anonymous> (/usr/local/lib/node_modules/firebase-tools/commands/serve.js:25:15)

I was able to prevent this error by commenting out the following lines in serve.js (obviously not ideal):
if (config.public && config.public !== '.') { logger.info(chalk.bold('Public Directory:'), config.public); }

I had a similar issue. If you go into the web-start directory and run:
firebase init
when you get to this question:

=== Hosting Setup

Your public directory is the folder (relative to your project directory) that
will contain Hosting assets to uploaded with firebase deploy. If you
have a build process for your assets, use your build's output directory.

? What do you want to use as your public directory?

You can use ./ here (make sure you tell it not to redirect links or overwrite index.html as well in the other steps for init).

When you get to step 13:

firebase.json has a section that does the same thing:

"hosting": {
    "public": "./",

Thanks @uzusan, I was sure it was a rookie error.

Thanks for the report guys. I'll fix this. It seems the alpha version of the CLI that I was using did not require the hosting/public attribute to be set but it now does...
