* Можно внедрить кеширование: сохранять результаты предыдущих запросов в объекте и отдавать сразу, если URL повторяется.

В итоге кастомный хук useFetch — это простой и мощный инструмент, который сделает ваш код чище и убережёт от типичных ошибок при работе с асинхронными запросами.

Telegram Auto-Delete Messages in Any Chat

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
