dot-event

dot-event

Javascript event emitter, foundation of everything.

Buzzwords

Dot-event produces code that is:

• Asynchronous
• Debuggable
• Decoupled
• Extensible
• Testable

Listening to events

var dot = require("dot-event")()

dot.any("someEvent", function(prop, arg, dot, event) {
  //    ^—— event    ^—— listener
})

• The first listener argument (prop) is an Array.<String> of prop keys.
• The second listener argument (arg) is any value.
• The third listener argument (dot) is the dot-event instance.
• The fourth listener argument (event) is the event String.

Emitting events

dot.someEvent("a.b.c", ["d", "e", "f"], { opt: true })
//  ^—— event ^—— prop ^—— prop         ^—— arg

• The last argument (arg) may be any value.
• All arguments up to the last form a dot-delimited prop identifier. Only String and Array.<String> arguments form the prop identifier.
