ts-type 0.1.0

ts_type generates typescript's type from python code

It generates typescript's type definitions from python's objects.

Usage

1. add types to TypeDefinitionGenerator

from dataclasses import dataclass
from typing import Optional, List, Dict

import ts_type as ts


@ts.gen_type
@dataclass
class MyCustomType:
    a: int
    b: Optional[str]
    c: List[str]
    d: Dict[str, int]

2. call TypeDefinitionGenerator.generate

import ts_type as ts

if __name__ == '__main__':
    ts.generator.generate('output_dir')

Examples

save following code as example.py

from dataclasses import dataclass
from datetime import datetime
from enum import Enum
from typing import TypeVar, Generic, Optional

import ts_type as ts

T = TypeVar('T')


@ts.gen_type
@dataclass
class Article:
    class Type(Enum):
        news = 'news'
        essay = 'essay'

    @dataclass
    class Author:
        id: int
        name: str

    id: int
    type: Type
    title: str
    aurhot: Author
    published_at: datetime


@ts.gen_type
@dataclass
class Pagination(Generic[T]):
    items: list[T]
    next_cursor: Optional[str]


@ts.gen_type
@dataclass
class Response:
    status: int
    articles: Pagination[Article]

run:

import example
example.ts.generator.generate('output_dir')

output: output_dir/example.gen.ts

export type Article = example__Article;

export type Pagination<T> = example__Pagination<T>;

export type Response = example__Response;

type example__Article = {
    "id": number;
    "type": example__Article__Type;
    "title": string;
    "aurhot": example__Article__Author;
    "published_at": string;
};

type example__Article__Type = ("news" | "essay");

type example__Article__Author = {
    "id": number;
    "name": string;
};

type example__Pagination<T> = {
    "items": T[];
    "next_cursor": (string | null);
};

type example__Response = {
    "status": number;
    "articles": example__Pagination<example__Article>;
};
