javascript - Node.js server/client module confusion, EventEmitter woes -


i'm trying write library can used in node.js or on client-side.

i'm running two issues:

  1. i can't seem export correctly. i'm using this doc. myclass = exports? , exports or @myclass = {} doesn't seem work, split files now.

  2. the library emits events; i'm hoping can clarify confusion on how more simply. follow me below :)

node.js:

library:

    {eventemitter} = require 'events'      class myclass extends eventemitter        emitsomething: (key, data) ->          @emit key, data  module.exports = myclass

required:

myclass = require 'myclass' myclass = new myclass()  myclass.on 'someevent', (data) ->   console.log data   # bare not using `emit` directly. data =    key: 'value'  myclass.emitsomething 'someevent', data

client-side

eventemitter included.

class myclass extends eventemitter    emitsomething: (key, data) ->      @trigger key, [ data ] # that's stupid.

the library file included in script , somewhere do:

myclass = new myclass()  myclass.on 'someevent', (data) ->   console.log data   data =    key: 'value'  myclass.emitsomething 'someevent', data

client-side

backbone.js/underscore.js included (not eventemitter library above).

class myclass    constructor: () ->      _.extend @, backbone.events    emitsomething: (key, data) ->      @trigger key, data # notice difference.

the library file included in script , somewhere do:

myclass = new myclass()  myclass.on 'someevent', (data) ->   console.log data   data =    key: 'value'  myclass.emitsomething 'someevent', data

so, uh, what's best way write library emits events both node , browser? eventemitter library seemed conflict backbone when had them both included (it needs work on node, , or without backbone). there's got simpler solution!

you should consider using browserify, let use myclass module client side since includes version of nodecore events.

so client side:

myclass = require('./myclass') myclass = new myclass()

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
