heroku-buildpack-nodejs VS dokku-postgres

No default language could be detected for this app. HINT: This occurs when Heroku cannot detect the buildpack to use for this application automatically. See https://devcenter.heroku.com/articles/buildpacks

Choose a buildpack explicitly https://devcenter.heroku.com/articles/buildpacks

Another alternative that comes to my mind it is to use the node.js buildpack and serve the static files using serve or similar.

Support for Buildpacks from Heroku

You use a buildpack.

Now that your app is registered to Heroku, we have to set up a buildpack.

My first instinct was to (cry) manually set the appropriate buildpack for a node.js server as mentioned by Heroku's Dev Center. However, Heroku states that...

Dokku is a popular, open-source, and self-hosted platform as a service (PaaS) that allows users to easily deploy and manage their applications, very similar to your own self-hosted Heroku. Under the hood, Dokku is powered by Docker, uses Heroku buildpacks by default, and has a number of official and community plugins.
