How to separate build files for dev and prod in Gulp?

Question

gulp.js

Hello. Tell me such a moment on Gulp. I have an index.html page where I have connected in a certain order, for example, 10 libs from bower and 10 more of my scripts for a total of 20 files.
1. How can I apply js hint to all these files for one gulp command
2. on another server, use the command to concatenate and minify all these files into 1 ???
I can imagine how to make a task for the first case, but I can’t imagine how to drive all 20 js files into 1 general one in the second case.

Answer 1

? gulp-concat + gulp-inject
