Arguments:

• path
  • Type: String
  • Description: path to the target key
• value
  • Type: depends on the key in the state
  • Description: value to set the desired key to in the state

Example

import FormService from '@zensen/form-service'

const MODEL = {
  firstName: '',
  lastName: '',
}

const onChange = (_dirty, state) => console.log('state:', state)

const formService = new FormService(MODEL, {}, onChange)

formService.apply('firstName', 'Tony')

Output:

state: {
  firstName: 'Tony',
  lastName: '',
}

Restrictions

• Only a single key can ever be modified along its branch in the state tree
• apply() cannot be applied to object-type keys unless clipPristine is set on that key’s selector
• Objects that can be modified must not alter the shape of that schema with the exception of going between null/object states
• The unsafe modifier flag can be set on keys in exceptional cases (such as multi-selects) where object/array mutations are required
