simple-model
Simple model for getting and setting values
var SimpleModel = require('simple-model');
var x = new SimpleModel();
x.on('change', function (prop, newVal, oldVal) {
console.log('change ' + prop + ' from ' + oldVal + ' to ' + newVal);
});
x.set('foo', 'bar');
// 'change foo from undefined to bar'
x.set('foo', 'baz');
// 'change foo from bar to baz'
x.get('foo');
// 'baz'Installation
$ npm install simple-model
Dependencies
API
SimpleModel
Create a new instance of a model
model.set(prop, value)
Set the value of prop as value
model.get(prop)
Return the value of prop
model.setMiddleware(fn)
Attach middleware for setting values
refer to attach-middleware for documentation
// resume from previous example
x.setMiddleware(function (prop, val, next) {
next(null, prop.replace(/ /g, '_'), 'val: ' + val);
});
x.set('foo bar', 'baz');
x.get('foo bar');
// undefined
x.get('foo_bar');
// 'val: baz'model.getMiddleware(fn)
Attach middleware for getting values
refer to attach-middleware for documentation
// resume from previous example
x.getMiddleware(function (prop, val, next) {
next(null, prop.replace(/ /g, '_'), 'getMiddleware: ' + val);
});
x.get('foo bar');
// 'getMiddleware: val: baz'Events
'change' (prop, newVal, oldVal)
Listen for all changes on the model
'change PROP' (newVal, oldVal)
Listen for a specific prop change on the model
Limitations
- Getting values must be synchronous. Let me know if an asynchronous model is needed
