Props

A prop is defined by adding a type hint to a class variable.

from vue import VueComponent

class ComponentWithData(VueComponent):
    prop: str

Types

Unlike Vue.js, vue.py enforces prop types (if not type hint is provided, it is a data field).

The following types are currently supported:

• int
• float
• str
• bool
• list
• dict

Default

By assigning a value to a prop, the default value can be defined.

from vue import VueComponent

class ComponentWithData(VueComponent):
    prop: str = "default"

Required

If no default value is given, the prop is automatically required.

Validator

With the @validator decorator are prop validators defined

from vue import VueComponent, validator

class ComponentWithData(VueComponent):
    prop: int

    @validator("prop")
    def prop_must_be_greater_than_100(self, value):
        return value > 100
