Nested Objects

The composition ability for combining validators together on props and objects opens up complex possibilities. Another great example is nested objects.

import validate, {
objectProps, required, length, range, every
} from 'strickland';
const personValidator = objectProps({
name: every([required(), length(5, 40)]),
address: objectProps({
street: every([required(), objectProps({
number: every([required(), range(1, 99999)]),
name: every([required(), length(2, 40)])
})]),
city: required(),
state: every([required(), length(2, 2)])
})
});
const person = {
name: 'Marty McFly',
address: {
street: {
number: 9303,
name: 'Lyon Drive'
},
city: 'Hill Valley',
state: 'CA'
}
};
const result = validate(personValidator, person);

Objects can be nested without any limits on depth. And any type of validator can be used anywhere in the tree.
