Equinox JS

This is a JS port of jet's Equinox.

Equinox is a set of low dependency libraries that allow for event-sourced processing against stream-based stores handling:

• Snapshots
• Caching
• Optimistic concurrency control

Notable differences from Equinox

TypeScript doesn't have DU's

Well, that's technically not true, we can approximate them as such:

type Data = { hello: "world" }
type Event = { type: "Something"; data: Data }

TypeScript doesn't have modules

We can replace them with namespaces, but people will look at you funny for using them for some reason 🤷.

export namespace Events {
  type Data = { hello: "world" }
  export type Event = { type: "Something"; data: Data }
}
