Provides server-side before/after hooks for Meteor methods

Meteor Method Hooks

Before/after hooks for Meteor methods

This package is old and hasn't been maintained in a while. Try this one, which has tests and is more recent: https://github.com/Workpop/meteor-method-hooks

Meteor >= 0.9	Meteor < 0.9
meteor add hitchcott:method-hooks	mrt add method-hooks

This server-only package extends Meteor with two methods:

• Meteor.beforeMethods
• Meteor.afterMethods

The beforeMethods method can be used for securing Meteor.methods based on the result of a definable function.

Here's an example for security, in /server/methods.coffee

Meteor.beforeMethods 'test', ->
  Meteor.users.findOne(@userId)?.admin

The above will prevent the test method from being executed unless the client is logged in as and has their admin field set to true.

Any beforeMethods that return false will stop the relevent method and any other hooks from executing.

Uses include:

• Security
• Logging
• [insert imaginative idea]

Example Usage

You can pass an array of method names, and the hooks will recieve the same parameters as the original method. For example:

if Meteor.isServer
  Meteor.methods
    'test1' : (str) -> console.log 'Hi', str
    'test2' : -> console.log 'second method'

  Meteor.beforeMethods ['test1','test2'], (str) ->
    console.log 'hook1', str

  Meteor.beforeMethods 'test1', ->
    console.log 'hook2'

  Meteor.afterMethods 'test2', ->
    console.log 'hook3'

if Meteor.isClient
  Meteor.call 'test1', 'Chris'
  Meteor.call 'test2'

will output

hook1 Chris
hook2
Hi Chris
hook1 undefined
second method
hook3

TODO

• Testing
• beforeAllMethods & afterAllMethods ?
• Hook up methods instantly (if they exist) rather than waiting for startup, and defer any unmatched hooks until after Meteor.startup.
