sugar-form v0.0.1

🍬 sugar-form

sugar-form provides a vue-modifier-like way to simplify common React DOM event handling:

import on from 'sugar-form'

<input {...on.keydown.enter.prevent.value(value => dispatch('SUBMIT', value))}/>

Usage

import on from 'sugar-form'

// Start with `on`. Then chain up sugars in any order.
<input {...on.sugar.sugar.sugar(listener)}/>

// Sugars can take args.
<input {...on(arg).sugar.sugar(arg)(listener)}/>

Sugars

Event binding

• on('KeyPress')

  Binds keypress event.

  Note: Event name must be CamelCase.

• on('KeyPress KeyDown')

  Binds both keypress and keydown events.

• .click

  Shortcut for on('Click').

  Supported shortcuts:

  • .click
  • .keyup
  • .keydown
  • .keypress
  • .change
  • .input
  • .submit
  • .focus
  • .blur

• Chaining

  on('Pause').keypress.keydown will bind them all.

• Capture

  Add .capture to bind ALL chained events in capture phase.

Event handling

• .stop

  Call event.stopPropagation() before running your listener.

• .prevent

  Call event.preventDefault() before running your listener.

Keyboard filtering

Note: These sugars are available for keyboard events.

• .key('Enter'), .key('Enter Tab')

  Filter out events whose .key is not included.

• .code(13), .code(13, 27)

  Filter out events whose .code is not included.

Modifier keys filtering

Note: These sugars are only available for mouse and keyboard events.

• .ctrl, .alt, .shift, .meta

  Filter out events whose .ctrlKey (or .altKey, .shiftKey, .metaKey) is false.

• Chaining

  .click.ctrl.shift ensures ALL these modifier keys are pressed.

Transforming

• .value

  Call your listener with event.target.value instead of event.

• .number

  Call your listener with +event.target.value instead of event.
