Package Exports

simple-model

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (simple-model) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
