Miso.Exception
Description
Synopsis
Types
data MisoException Source #
The MisoException type is used to catch Component-related mounting errors.
The two mounting errors that can occur during the lifetime of a miso application are
- Not Mounted Exception
This occurs if a user tries to call sample myComponent when myComponent is currently
not mounted on the DOM.
- Already Mounted Exception
It is a requirement that all Component be named uniquely
(this is to avoid runaway recursion during mounting).
If we detect a Component is attempting to be mounted twice
this exception will be raised.
Other exceptions can arise, but its up to the user to handle them in
the update function. All unhandled exceptions are caught in the event loop
and logged to the console with console.error()
