Utility belt implementation of the compose standard

This module is the new cool modern version of the stampit module. Consider @stamp/it as stampit v4.

Usage

Install:

$ npm i -S @stamp/it 

Import:

import stampit from '@stamp/it'

Or import utility functions only:

import {
    methods,
    
    props,
    properties,
    
    statics,
    staticProperties,
    
    conf,
    configuration,
    
    deepProps,
    deepProperties,
    
    deepStatics,
    staticDeepProperties,
    
    deepConf,
    deepConfiguration,
    
    init,
    initializers,
    
    composers,
    
    propertyDescriptors,
    
    staticPropertyDescriptors
} from '@stamp/it'

const Stamp1 = methods({ foo() {} })
const Stamp2 = props({ bar: 'my bar' })
const Stamp3 = conf({ my: 'configuration' })
const Stamp4 = init(function (options, {stamp, instance, args}) {
  console.log('bla')
})

API

Arguments

See more examples in this blog post.

Create a new empty stamp:

const S1 = stampit()

Create a new stamp with a method:

const S2 = stampit({
  methods: {
    myMethod() { }
  }
})

Create a new stamp with a property:

const S3 = stampit({
  props: { // or properties:
    myProperty: 42
  }
})

Create a new stamp with a static property:

const S4 = stampit({
  statics: { // or staticProperties:
    myStaticProperty: 42
  }
})

Create a new stamp with initializer(s):

const S5 = stampit({
  init: function () { console.log('hi form initializer') }
})
// or
const S6 = stampit({
  init: [ // or initializers:
    function () { },
    function () { }
  ]
})

Create a new stamp with a configuration:

const S7 = stampit({
  conf: { // or configuration:
    myConfiguration: { anything: 'here' }
  }
})

Compose the stamps above together:

const Stamp = compose(S1, S2, S3, S4, S5, S6, S7)
console.log(Stamp)
// { compose: [function] { properties, methods, staticProperties, initializers, configuration } }

const obj = Stamp()
console.log(obj)
// { myProperty: 42 }
console.log(Object.getPrototypeOf(obj))
// { myMethod: [function] }

Static methods

The Stamp.create() static method

Calling Stamp.create() is identical to calling Stamp().

Shortcut static methods

All stamps receive few static properties. These are taken from the @stamp/shortcut stamp. For example:

stampit()
  .props({ foo: 'foo' })
  .deepConf({ things: ['bar'] })
  .methods({ baz() {} })
  // etc

Shortcut exported methods

The module exports a range of shortcut methods. These are taken from the @stamp/shortcut stamp.

import {methods, props, init, statics, /* etc */} from '@stamp/it'

Each returns a stampit-flavoured stamp.

NOTE! Unlike the @stamp/shortcut module, all the exported functions of @stamp/it are stampit-flavoured. Meaning that:

import {methods} from '@stamp/it'
const Stamp = methods({ foo() {} })
.props({bar: 1})                    // THIS WILL WORK
.statics({baz: 2})                  // AND THIS WILL WORK TOO
