Hooks

The hook system allows us to hook on to the lifecycle of the API request/context and somehow impact it.

Below are the hooks available in GramIO:

• onStart - called when the bot is started
• onStop - called when the bot stops
• onError - called when an error occurs in the contexts
• preRequest - called before sending a request to Telegram Bot API (allows us to impact the sent parameters)
• onResponse - called on API request response (only if success)
• onResponseError - called on API request response (only if errored)
