How to minify dynamic generated code?

Some times you need code that is dependent on parameter. Like having one up to five analog reads depense on your device. Having it readable eats up lots of space.

Is there a way to minify Sting module?

count = 3;
name = 'analogRead';
var APINS = [ D28, D3, D4, D30, D29 ];
var analogRead = {};

var buildModule = (c) =>{
  var module = "", i = 0;
  module = `exports = function (interval) {
  var a0 = 0
    , a1 = 0
    , a2 = 0
    , a3 = 0
    , a4 = 0
  ;
  setInterval(() => {
`;
  for (i = 0; i < count; i++) {
    module += '    a'+i+' = analogRead('+APINS[i]+');\n';
  }
  module +=`    print(`;
      module += ' a'+0+'.toFixed(3)\n';
  for (i =1; i < count; i++) {
    module += '         , a'+i+'.toFixed(3)\n';
  }
  module +=`    );
   }, interval);
}`;

  require('Storage').write(name, module);
  print(module);
};

buildModule(count);
analogRead = require(name);

output

exports = function (interval) {
  var a0 = 0
      , a1 = 0
      , a2 = 0
      , a3 = 0
      , a4 = 0
  ;
    setInterval(() => {
      a0 = analogRead(D28);
      a1 = analogRead(D3);
      a2 = analogRead(D4);
      print( a0.toFixed(3)
           , a1.toFixed(3)
           , a2.toFixed(3)
      );
   }, interval);
