在DigitalOcean上部署Vue.js应用程序

I made an app using Vue.js on the frontend and Slim PHP on the backend and I want to deploy it on a DigitalOcean droplet. So far, I've managed to do the following:

• Created a Ubuntu 16.06 droplet
• Updated it
• Installed Apache
• Installed MySQL + phpmyadmin
• Installed PHP
• Edited dir.conf (I put index.php on front of the list)
• Restarted Apache
• Prepared the Vue app with npm run build
• Copied the index.html and the /dist folder to /var/www/html/myapp

When I try to open myserverip/myapp in a browser, it just loads an blank html document. I noticed that the title is correct, but the #app div containing the application doesn't render. What am I doing wrong? Do I need to spin up a node.js server, install another service or something else?
