prmhub v1.0.1

Hub

Hub is made to reduce redundant async calls.

Example

Program triggers multiple async calls at the same time, using hub, only one call will be actually send out. Also the result could be saved by setting a timeout(in ms), null or undefined means permanent cache.

Interface

• ctor
  1. fn, a function takes nothing and return a promise
  2. timeout: ms (0 for nocache and null/undefined for permanent cache)
• timeout (boolean)
• get (Promise)
