How to dynamically add imports

I want to dynamically create an HTTP router using custom plugins/middleware, currently, I am using a config.yml for example:

plugins:
  - waf
  - jwt 
  - cors

After parsing the yml file I create the routes like this:

route := violetear.New()
chain := middleware.New() 
for _, plugin := range Plugins {
    chain := chain.Append(plugin)       
}
router.Handle("/test", chain.Then(myHandler))
log.Fatal(http.ListenAndServe(":8080", router))

For this to work, I would have to include all the plugins in the import section, something like:

import (
   "net/http"

   "github.com/nbari/violetear"
   "github.com/nbari/violetear/midleware"
   
   // How to deal with this
   "github.com/example/waf"
   "github.com/example/jwt"
   "github.com/example/cors"
)

I would need to change the current config format to be something more useful/generic probably something like:

plugins:
  - [github.com/foo, foo]
  - [github.com/bar, bar]

But besides that what could be the best approach to "dynamically" create the imports or to generate the code the one later could be compiled?

Any ideas?

Go is a statically linked language. This means if a package is not referenced at compile time (from your .go source files), that package will not be linked / compiled into the executable binary, which implies it will not be availabe at runtime.

So the easiest is to just use imports.

If you want truly dynamic configuration, plugins introduced in Go 1.8 may be an option for you, but using plugins complicates things and I would only use that as a last resort. Also note that plugins currently only work on linux.
