Migrating from @telegram-apps/init-data-node

This guide provides a summary of the migration process from @telegram-apps/init-data-node to @tma.js/init-data-node.

parse

• The function now has no way of returning a camel-cased version of init data. Instead, it always returns them in form they were passed from Telegram. Nevertheless, you can import the deepSnakeToCamelObjKeys function from the package in order to deeply camelize keys:

import { deepSnakeToCamelObjKeys, parse } from '@tma.js/init-data-node';

const initDataCamelCased = deepSnakeToCamelObjKeys(parse('...'));

Errors

• The following functions were removed:
  • isAuthDateInvalidError
  • isSignatureInvalidError
  • isHexStringLengthInvalidError
  • isSignatureMissingError
  • isExpiredError

Instead, you should use the errors' static is() method:

import { ExpiredError } from '@tma.js/bridge';

if (ExpiredError.is(someValue)) {
  // someValue is instance of ExpiredError.
}
