A modern (whatever that means) WordPress skeleton to use for creating Composer based WordPress installations.

Create a new project with composer:

$ composer create-project chrisguitarguy/wordpress-skeleton new-site ~1.0
$ cd new-site

From here you can add new dependencies to composer.json, remove the example plugins and themes and do any modifications you need.

The plugins and themes you build should be autoloaded with composer.json. See the example plugin line there right now:

{
    "autoload": {
        "psr-4": {
            "Chrisguitarguy\\Skeleton\\ExamplePlugin\\": "web/content/plugins/example/inc/"
        },
        "files": [
            "web/content/plugins/example/inc/functions.php"
        ]
    }
}

Only autoload file that declare symbols (functions, contants, classes)! Not files that cause side effects.

Because not all packages can go in /vendor, you'll need to manually exclude things via .gitignore (or .hgignore, .svnignore, etc). There's an example here with the WordPress SEO plugin which is ignored in .gitignore:

/web/content/plugins/wordpress-seo

Correct. This is meant to get you started, not make all the choices for you.

The various salts are missing, for example. You could add those yourself to another file and include it from wp-config.php or let WordPress generated them for you and save them in the database (what happens when they are missing).

Because composer is nice and WordPress needs a good dose of modern development practices.
