Validating a tuple, for example:
type UserInfo = [string, number]
const user: UserInfo = ['John', 32]
useSchema(user, [validateUsername, validateAge])
from reach-schema.
For arrays you can use this approach. What do you have in mind?
useSchema(
{
'users.name': (value, pointer) => value.length > 10,
},
{
users: [
name: 'Marco'
],
},
)
from reach-schema.
That looks like a good start, @marcosvega91!
I was thinking that useSchema
should be able to accept a root-level array as well. Something like:
useSchema([1, 2, 3], [1, 2, 3]) // OK!
The complexity comes with describing a spec of expected data.
// Validate each Array member against a predicate.
useSchema([1, 2, 3], (value) => !isNaN(value))
// Validate each Array member against a unique predicate.
useSchema(
[1, 'admin', { firstName: 'John' }],
() => [
(value) => !isNaN(value),
(value) => value === 'admin',
(value) => ({
// Regular schema validation
firstName: value => value === 'John'
})
]
)
It gets more complex, when you wish to validate a portion of Array against a general predicate, and a portion against exact predicate functions.
I think we should approach this from the specification point of view, defining what features should be supported.

Array of course should be implemented 💯
I'm thinking about the use of array with multiple predicate...mmmm.. Do you have a real example of this use?
