custom

Building custom plugins in the Psychic ecosystem is incredibly simple. You can utilize the app.plugin method (this exists both on the DreamApplication and PsychicApplication classes) to register custom behavior, enabling you to provide encapsulated logic to extend both dream and psychic exactly the same way you would if you were writing custom code into the conf/app.ts and conf/dream.ts files directly.

// conf/app.ts
export default async (psy: PsychicApplication) => {
  ...
  psy.plugin(myPlugin)
}

async function myPlugin(psy: PsychicApplication) {
  // this function will be called after both Psychic and Dream
  // are initialized, enabling you to extend both with
  // custom behavior
}

Psychic also ships with a few helpful plugins that you can opt into during app provisioning. These are utilities that most applications may not need, but for the ones that do, they provide a powerful pack of extra features.

Psychic workers

The workers plugin enables you to easily provision background job systems that integrate seamlessly into your app's service and model layers, enabling you to easily kick functions off to a background system whenever you see fit.

Psychic websockets (beta)

The websockets plugin provides mechanisms for leveraging redis pubsub mechanisms to bind socket.io to your app, enabling you to emit messages to your users no matter which web instance they are connected to.

Snapshotable

The Snapshotable plugin plugin provides a powerful mixin to enable you to easily take snapshots of your model layer.
