node.js - Generic JavaScript Models using Composition -
i working on node.js application couple of javascript model this: function role(data) { this.data = data; ... } role.prototype.save = function(...) {...} role.findbyid = function(...) {...} role.findall = function(...) {...} all of them using same (similar) logic of functions, need different implementation saving , on. idea refactor them using kind of composition. current solution combination of using inheritance prototype functions , adapter static functions. looks this. var _adapter = new databaseadapter(schema, table, role); function role(data) { model.call(this, _adapter, role._attributes) this.data = data; ... } role._attributes = { name: '' } role.prototype.save = function(...) {...} role.findbyid = function(...) { _adapter.findbyid(...); } role.findall = function(...) { _adapter.findall(...) } but, not happy current solution, because developers need know lot of implementation details create new model. so, hope show me better approach so...
