Meteor Method Hooks
Before/after hooks for Meteor methods
This package extends Meteor with four methods:
Meteor.beforeMethod
Meteor.afterMethod
Meteor.beforeAllMethods
Meteor.afterAllMethods
This package differs from hitchcott:method-hooks in that:
- You can add hooks for all methods
- It works on both client and server
- You can add and remove hooks at runtime.
- After methods can change the methods result
The beforeMethod
method can be used for securing Meteor.methods
based on the result of a definable function.
Any beforeMethod
that throws an error will stop the relevant method and any other hooks from executing.
If you want to prevent further execution without triggering an error, you can just return 'false' from within your hook.
Here's an example for checking user login:
1Meteor.beforeMethod('test',function(){ 2 if(!Meteor.userId()) throw new Meteor.Error(403,"Forbidden"); 3})
You can also pass an array of method names as first parameter.
Uses include:
- Security
- Logging
- [insert imaginative idea]
The before methods get the same arguments as the original method,
The after method can get the current result from this.result
or the error from this.error
If it returns a value that is not undefined, then this will replace the original result.
