Want branded strings or more specific

Want branded strings or more specific types?

I just realized this just works:

defineSchema({
  myTable: defineTable({
    myField: v.string() as Validator<MyStringType>
  })
)}

defineSchema({
  myTable: defineTable({
    myField: v.string() as Validator<MyStringType>
  })
)}

defineSchema({
  myTable: defineTable({
    myField: v.string() as Validator<MyStringType>
  })
)}

defineSchema({
  myTable: defineTable({
    myField: v.string() as Validator<MyStringType>
  })
)}

myField

myField

myField

myField will be typed as

MyStringType

MyStringType

MyStringType

MyStringType when you get it from the DB, and give you errors on functions like

withIndex

withIndex

withIndex

withIndex if your parameter isn't

MyStringType

MyStringType

MyStringType

MyStringType when comparing against

myField

myField

myField

myField

Note: this isn't runtime validation, this is just type annotations to help you catch bugs & be more descriptive.
