Question about extend!

[marsanla]

Hi it's possible to extends functionality from a file in one folder to other?. For example:

We have this structure:

- components
    - c1
        - routes.js
- core
    - c1
        - routes.js

core/c1/routes.js:

module.exports = {
   hello: function() {
       return 'hello';
   },
   world: function() {
       return 'world';
   }
};

components/c1/routes.js:

module.exports = {
   hello: function() {
       return 'welcome';
   }
};

At the end i want to get this module:

module.exports = {
   hello: function() {
       return 'welcome';
   },
   world: function() {
       return 'world';
   }
};

Should i write something in particles? Or Scatter control that?

Thanks and best regards

You can find in the Guide an example of how extend works: https://github.com/mariocasciaro/scatter/wiki/Guide#extend-and-override-modules

Basically, you first need to specify that the components particle extends the core particle, you can do that by specifying the override option in the particle.json of components. Then, you need to inject from components/c1/routes a reference to the overridden module, in your case c1/routes which Scatter will resolve to core/c1/routes. Next, augment the original object with your extensions. Please notice that, for obvious reasons, this mechanism works only if the extending module is a factory and receives the extended module as an argument.
