Pseudo-Blocking Async Javascript Functions

Installation via NPM

npm install blocking


blocking = require 'blocking'

# an async function
get_name_async = ( id, cb ) -> ...

# trasnsform to a blocking/sync function
get_name = blocking get_name_async

# do something using the sync function
f1 = ->
  # notice that we can call toUpperCase on the value
  # because this function now returns sychronously
  get_name( 8 ).toUpperCase()

# to execute the above function we need to unblock it
f1 = blocking.unblock f1

# and the function is async again
f1 (err, res) -> console.log err, res
