Component Helpers

These are a collection of useful helper functions that will make development easier.

import {...} from 'two-way-rest

mapIf
arguments: (possibleIterator, mapFunction, noInteration*)
example:

mapIf(children, child=>child.get('name'), <div>No Children Exist</div> )

customAction
arguments: (args, customFn)
content: This function can be used during the actioncycle to perform a custom action on the state example:

<TWRCreate tree='users' callforward={args=>
  customAction(args, state=>state.delete('dogs'))
  return args
}/>

createErrors
arguments: (instance from create, update, or destroy)
content: This function will output the errors in an instance using standard bootstrap tags example:

<TWRCreate noErrors tree='users'>
  <CreateUser />
</TWRCreate>
}/>
function CreateUser(props){
  return <div>
    <input type='text' name='name' />
    {createErrors(props.instance)}
    <button>Submit</buttom
}
==> If an error is thrown
<div className='default-errors'>
  <span className='label label-danger'>Error</span>
<div>
