Generally these components connect to a TFW event handler running on the backend.
Communication is handled via simpe APIs exposed by these event handlers – over TFW messages.
These APIs are documented in the `baseimage-tutorial-framework` repository as docstrings in the [lib/tfw/components](https://github.com/avatao-content/baseimage-tutorial-framework/tree/master/lib/tfw/components) directory (this is where the event handler implementations live).

This event handler spawns a `bash` session and a `pty` (pseudoterminal).
It connects the master end of the `pty` to the emulator running in the browser and the slave end to `bash`.
This essentially provides a fully functional terminal session in the browser.
You can write to it (and thus execute commands) and read what commands were executed in `bash` using the API exposed by the `TerminalEventHandler` instance.
This essentially provides a fully functional terminal session for your users in the browser (a convenient alternative for an SSH session).
This terminal is fully under your control:
You can write to it (and thus execute commands) and read what commands were executed by the user using the API exposed by the `TerminalEventHandler` instance.
This enables you to pre-type or execute commands for the user and figure out what they are doing in the terminal.
