Some examples:

  • User calls require() outside the body of design functions
  • Design function is dependent on code written in top-level.
    ...

Reduce functions are not properly extracted

The output json for the view when outputting dry mode into a file looks like this

{
      "map": " (function(){\n\nreturn function (doc) {\n\n    if (doc.amp && (doc.at || doc.until)) {\n      var date = doc.until || doc.at;\n      emit(doc.amp, new Date(date.time + date.offset).getTime());\n    }\n  };\n\nvar reduce = exports.reduce = function reduce() {\n  return function (keys, values) {\n    return Math.max(values);\n  };\n};\n\n}())",
      "reduce": " (function(){\n\nvar map = exports.map = function map(_ref) {\n  var emit = _ref.emit;\n  return function (doc) {\n\n    if (doc.amp && (doc.at || doc.until)) {\n      var date = doc.until || doc.at;\n      emit(doc.amp, new Date(date.time + date.offset).getTime());\n    }\n  };\n};\n\nreturn function (keys, values) {\n    return Math.max(values);\n  };\n\n}())"
    },

So the map function ends up with the reduce function in the body and vice versa.

This is the source for the view

export const map = ({emit}) => doc => {

  if(doc.amp && (doc.at || doc.until)) {
    const date = doc.until || doc.at;
    emit(doc.amp, new Date(date.time + date.offset).getTime());
  }

};

export const reduce = () => (keys, values) => Math.max(values);

And it gets transpiled to

(function(){

var map = exports.map = function map(_ref) {
  var emit = _ref.emit;
  return function (doc) {

    if (doc.amp && (doc.at || doc.until)) {
      var date = doc.until || doc.at;
      emit(doc.amp, new Date(date.time + date.offset).getTime());
    }
  };
};

return function (keys, values) {
    return Math.max(values);
  };

}())

And

(function(){

return function (doc) {

    if (doc.amp && (doc.at || doc.until)) {
      var date = doc.until || doc.at;
      emit(doc.amp, new Date(date.time + date.offset).getTime());
    }
  };

var reduce = exports.reduce = function reduce() {
  return function (keys, values) {
    return Math.max(values);
  };
};

}())
