Access function in another module.export in a separate file

Question

Access function in another module.export in a separate file

I have several javascript files that contain different parts of my node application. They are required using the logic below. I want to access a function in one file1.js from file2.js, but have had little success so far. Any help would be appreciated, thanks.

app.js: This is the file where I start my server and include all the express routes.

require(path_to_file+'/'+file_name)(app, mongoose_database, config_file);  //Require a bunch fo files here in a loop.

file1.js: This is an example file that is required using the code above.

module.exports = function(app, db, conf){
  function test() {  //Some function in a file being exported.
    console.log("YAY");
  }
}

file2.js: This is another file required using the code above. I want to access a function in file1.js from within this file (file2.js).

module.exports = function(app, db, conf){
  function performTest() {  //Some function in a file being exported.
    test();
  }
}

node.js
express

Answer 1

file1.js

module.exports = function(app, db, conf){
  return function test() {
    console.log("YAY");
  }
}

Note you need to return the function.

file2.js

module.exports = function(app, db, conf){
  return function performTest() {
    var test = require('./file1')(app, db, conf);
    test();
  }
}

(some other file)

var test = require('./file2')(app, db, conf);
test();

or

require('./file2')(app, db, conf)();

The function you have right now in file1 is scoped only to the function within the exports. Instead, you want to export an object with each function being a member of that object.

//file1.js
module.exports = {
    test: function () {
    }
};


//file2.js:
var file1 = require('./file1.js');
module.exports = {
    performTest: function () {
        file1.test();
    }
}
