nitroglycerin

Nitroglycerin

Makes JavaScript functions so volatile and explosive that they immediately throw on errors.

This is mostly useful for testing and simple command-line scripts. In production you most likely don't want to throw exceptions.

How it works

Let's say you have a small piece of test code that needs to set something up:

resetDatabase (err) ->
  if err then throw new Error(err)
  createUser name: 'Alfred Nobel', (err, alfred) ->
    if err then throw new Error(err)
    # run your tests using alfred here

Checking that these calls didn't error out requires a bit of ceremony in Node.js, either in the form of manual error checking as described above, promises, or async.waterfall. Nitroglycerin removes most of this ceremony:

N = require 'nitroglycerin'

resetDatabase N ->
  createUser name: 'Alfred Nobel', N (alfred) ->
    # run your tests using alfred here

The functions wrapped in Nitroglycerin will immediately throw an exception when they receive an error or execute the callback with the error argument stripped.
