Share a service between two or more plugins

Question

I need to share a payment service class between two (or more) plugins and am wondering if Kuzzle's Pipes are the best solution for that?

I made a poc which seems to work, nevertheless, I don't found any similar example on kuzzle's plugins (like for hooks with Kuzzle-plugin-logger)

What are the other options?

Answer 1

The best way to share functionalities between plugins is to declare them as API actions.

You could expose your payment service features by creating a plugin named payment for example and declaring a controller inside.

this.controllers = {
  card: {
    pay: request => ...,
    fraudCheck: request => ...
  }
};

Then you can use the embedded SDK to call those actions from another plugin. The request will be directly transmitted to Kuzzle without using the network.

this.context.accessors.sdk.query({
  controller: 'payment/card',
  action: pay,
  number: '...',
  ccv: 543,
  ...
});

Since Kuzzle rights are whitelist based so external users will not be able to call your actions unless you explicitly specify it in their roles.
