@telegram-apps/transformers

The package that provides valibot schemas and related utilities to work with the @telegram-apps/types typings.

Schemas' Generators

Schemas' generators are functions accepting true, if the output must be deeply camel-cased.

The schema generator's name ends with the Query suffix if it creates a valibot schema accepting query parameters presented as a string or an instance of URLSearchParams. It also may end with the Json suffix accepting a JSON object presented as a string.

initDataQuery

The initDataQuery generator returns a new schema for init data.

import { initDataQuery } from '@telegram-apps/transformers';
import { create, is } from 'valibot';

const initData = 'user=%7B%22id%22%3A279058397%2C%22first_name%22%3A%22Vladislav%22%2C%22last_name%22%3A%22Kibenko%22%2C%22username%22%3A%22vdkfrost%22%2C%22language_code%22%3A%22ru%22%2C%22is_premium%22%3Atrue%2C%22allows_write_to_pm%22%3Atrue%2C%22photo_url%22%3A%22https%3A%5C%2F%5C%2Ft.me%5C%2Fi%5C%2Fuserpic%5C%2F320%5C%2F4FPEE4tmP3ATHa57u6MqTDih13LTOiMoKoLDRG4PnSA.svg%22%7D&chat_instance=-9019086117643313246&chat_type=sender&auth_date=1736362318&signature=JUPYm_qmf8hJYSux535eNDg_a5ZdcOkS6yZMkEUGS09zcXoIopCn3DOuNCa5aWH0PQGaUGGMAaq9MeaMg-6EBg&hash=14cd9c9eeebf82370b20f4df23af9439d00f6da2837dd20e17ed3b03ab99cd9c&additional_prop=1';
