Python type code generator

Project description

Build Status codecov pyup


Code generator that converts from Python types (implemented by dataclasses) to TypeScript interfaces


  • Python 3.7 (need dataclass)


pip install pytypegen


from pytypgen.core import contracts_to_typescript, Contract

class Gender(Enum):
    male = 1
    female = 2

class Address(Contract):
    street: str

class Person(Contract):
    name: str
    gender: Gender
    birth_date: datetime.datetime
    addresses: Optional[List[Address]] = None

print(contracts_to_typescript(dataclasses=[Gender, Address, Person]))

Will generate the following TypeScript code:

export enum Gender {
  male = 'male',
  female = 'female'

export interface Address {
  street: string

export interface Person {
  name: string
  gender: Gender
  birth_date: string
  addresses?: Array<Address>|null

Development Setup

  • Run make setup. This will setup a pre-commit hook which creates README.rst file.
  • Run pip install -r dev-requirements.txt, preferably in a virtualenv.
