Question

I have a function defined called func1 in file file_a.js

I have another file file_b.js, in which I want to use the function func1.
Can I do this inside mongo environment?

Mongodb console can take multiple input file loaded in order specified.

Or you can use the built in load function like this

➜  mongotest  cat test.js
load("test2.js");
print("test.js");
foo();
➜  mongotest  cat test2.js
var foo = function() {
  print("test2.js");
};

➜  mongotest  mongo test.js
MongoDB shell version: 2.0.6
connecting to: test
test.js
test2.js

test.js is the file given to mongodb console, it loads test2.js(containing function foo) and calls foo
