@MikeYermolayev Hi, You can compose in multiple objects with Type.Intersect()
.
const A = Type.Object({ // type A = {
x: Type.Number(), // x: number,
y: Type.Number(), // y: number
}) // }
const B = Type.Object({ // type B = {
a: Type.Number(), // a: number,
b: Type.Number(), // b: number
}) // }
const C = Type.Intersect([A, B]) // type C = A & B
With respect to things like Pick
and Omit
, currently TypeBox schemas are additive only so it's currently not possible to do things like...
const Vector3 = Type.Object({
x: Type.Number(),
y: Type.Number(),
z: Type.Number(),
})
// subtractive
const Vector2 = Type.Pick(Vector3, ['x', 'y'])
// or
const Vector2 = Type.Omit(Vector3, ['z'])
Instead this would be expressed as.
const Vector2 = Type.Object({
x: Type.Number(),
y: Type.Number()
})
// additive
const Vector3 = Type.Intersect([Vector2,
Type.Object({
z: Type.Number()
})])
Implementing Omit
and Pick
would be interesting though, may actually look into this in future.
Hope this helps!

Oh, sorry, haven’t noticed it in the docs. Should’ve read more carefully)
Thank you👍🏻
