Migration

Version 7

The message parameter to TypedError is now
required. Previously message was optional
for TypedError.

The WrappedError class now exposes the error that
is being wrapped as a cause field instead of an
original field.

The following properties have been reserver on the
wrapped error class: cause, fullType, causeMessage

Version 5

There were no breaking changes...

Version 4

The TypedError function now has mandatory arguments.
The type and message arguments for TypedError
are required.

Version 3

The TypedError class now uses string-template for
message formatting.

Previously:

var FooError = TypedError({
  type: 'foo.x'
  message: 'Got an error %s'
});

FooError('Oops');

Currently:

var FooError = TypedError({
  type: 'foo.x',
  message: 'Got an error {ctx}',
  ctx: null
});

FooError({ ctx: 'Oops' });
