Does grafana minify plugin js files?

I have followed the below steps -
Got the grafana code v5.4.3
Installed the backend using -
go run build.go setup
go run build.go build
Followed below steps to build the frontend -
npm install
npm install -g grunt-cli
I was able to get grafana running at http://localhost:3000.

Then I introduced my dashboard files and plugin files.
After running grafana at http://localhost:3000, I saw that the plugin js files are not minified in the browser. They are loading one by one.

Then I did grunt build and grunt release for a minified build.
grunt release created a zip file under dist folder.

When I unzip the file, I see that it does not contain bin folder.
How do I use this zip file to serve minified files while running grafana?

No, that is up to each plugin build steps that is before publishing

Thanks Torkel!

The zip file that I get by doing grunt release, how do I use it run grafana?
