aiogram 3 Developer-Telegram Bot Development Framework

Example

Using the Router class to create modular handlers that can be reused across different projects.

Scenario

In a project where you need to handle messages, commands, and callbacks separately, the Router allows you to organize these handlers into distinct modules that can be included or excluded as needed.

Example

Implementing a middleware to log all incoming messages or to manage user sessions.

Scenario

If your bot needs to track user interactions for analytics, you can create a middleware that logs every message received and processed by the bot.

Example

Using Magic Filters to simplify event handling.

Scenario

When you need to filter messages based on content, such as handling only text messages that contain specific keywords, Magic Filters can streamline this process, making your code cleaner and easier to maintain.

Example

Managing multi-step user interactions with FSM.

Scenario

For bots that require a multi-step process, like filling out a form or guiding a user through a series of questions, the FSM feature allows you to manage the state of the conversation efficiently.

Example

Dynamically generating inline or reply keyboards based on user input.

Scenario

In scenarios where the options presented to the user depend on previous choices or external data, Keyboard Builders provide a flexible way to create complex, interactive UIs within the chat.
