You can use it as is without passing any option, or you can configure it as explained by Socket.io doc.
Hook
The plugin also adds an onClose
hook which closes the socket server when the fastify
instance is closed.
Typescript
From v4 types will no longer be included in the plugin package but will need to be installed separately:
npm i -D types-fastify-socket.io
This is necessary to allow, eventually, the developer to be able to define custom types and make use of the socket.io
new types system (doc).
