change processor (node.js)
Makes it easy to compare objects and based on the differences decide what code to run.
Sample
JavaScript
var changeProcessor = var personChangeProcessor = ; var original = name : first: "Bob" second: "Marshall" var updated = name : first: "Robert" // NOTE - Different value second: "Marshall" var { console; } ;
The output from this will be
changed - name
changed - name.first
all done
Note even though we only changed name.first
the event for name
was raised too.
Examples
The project comes with examples in the examples directory:
node examples/simple
node examples/allinOneFile
Tests
First install mocha:
npm install mocha -g
Run the tests using npm test
or:
mocha -R spec spec/testFixture spec/ -w -G --recursive
Future
- A change to a property could trigger further changes and we should probably then call their appropriate handlers (avoiding cycles).
- Suitable reporting of errors that occur inside
changeTo
methods. - Optional built-in logging using winston.
