I have a windows c++ DLL. It provides some functions like add(1,2). But I don't have the source code for this DLL, is it possible call functions in this DLL through nodejs, I mean, through web side and http. If it possible, what should I do?

Did you check out the ffi nodejs library? https://github.com/node-ffi/node-ffi

var ffi = require('ffi');

var libm = ffi.Library('libm', {
  'ceil': [ 'double', [ 'double' ] ]
});
libm.ceil(1.5); // 2
