Clase del Miércoles 10/11/2021 (Semana C)

Vamos a intentar ponernos al día con las prácticas anteriores.

Tenemos una nueva práctica en camino sobre las subscripciones en GraphQL:

Lab: GraphQL Subscriptions

• GraphQL Subscriptions

Subscriptions are based on three technologies:

1. EventEmitter.
   • Review the chapter on EventEmitters.
   • If you want to practice more with the event emitters you can optionally do the lab networking.
2. Another concept that you have to know before going to GraphQL subscriptions is Async Generators. You can optionally do the laAsync Generators
3. The third technoloy you need to know is websockets. You can optionally do the lab Websockets
