Schemas
We have two models of props for storages, the common props, and the virtual props.
In common props you can set the default type and value. These props can be modified.
Virtual props perform a function every time they are called and trigger change events when a listener
is declared in it through the listener property
{
schemas: {
firstname: {
type: 'string',
default: 'John'
},
lastname: {
type: 'string'
},
fullname: {
async get(){
const { firsname, lastname } = await this.get()
return this.firstname + ' ' + this.lastname
},
listener: ['firstname', 'lastname']
}
}
}
type
string
required
Prop value type. Are accepted:
- string
- number
- array
- object
- boolean
default
string
Default value of prop.
get
function
Function that will be executed when called.
listener
array
When set, the virtual prop raises an event when one of the properties described in the array is modified.
validation
function
Validation Function Always performed before the prop is monified. Receives the future value of prop as a parameter, be a common function, or asynchronous.
When common, expects a Boolean return, if true, passed validation, if false, did not pass.
When asynchronous (Promise) waits for the end of the function execution, to deny the validation it is necessary to throw an exception error, example:
throw new Error('Validation Error!')
