No file watcher & browser refresh in `patternlab:serve` gulp task.

[ringods]

I am using Pattern Lab Node v3.0.0-beta-1 on Mac, with Node v8.12.0, using a Gulp Edition (tested with Gulp v3.9.1 and v4.0.0).

Expected Behavior

When running gulp patternlab:serve, I want the local server to start and the file watcher to pick up changes with the cycle ending in a browser refresh.

Actual Behavior

The local server is started, but any change to my patterns is not picked up and there is no browser refresh. A manual refresh doesn't make a difference.

Steps to Reproduce

Create a new project and install PL 3.0.0-beta-1 with edition-node-gulp (on gulp 3.9.1). Just use the generated gulpfile.js with task patternlab:serve.

I can confirm that I had the same issue.

I had the same issue as well! I managed to fix this by updating the serve function in the gulpfile.js to:

function serve() {
    return patternlab.server
        .serve({
            cleanPublic: config.cleanPublic,
            watch: true
        })
        .then(() => {
            // do something else when this promise resolves
        });
}

Adding the watch: true is the important part!

@bmuenzenmeyer maybe that should be set in the default gulpfile or it should be set to watch: argv.watch to match the build function.

Adding watch: true fixes watching patterns, but there is no reload in the browser when I change CSS.

I'm seeing the same issue while using edition-twig (php engine) and starterkit-twig-demo. I'm using Pattern Lab Node v3.0.1. Any workarounds available without gulp?
