It'd be great for the invariant
to support a custom error class to use instead of the InvariantError
:
Line 25 in 6f4006a
The @mswjs/data library utilizes different error types to distinguish between operational and other exceptions. It cannot use invariant
because it always throws the same error class.
class MyError extends Error {}
invariant.as(MyError, 'Failed to execute "%s" on "%s"', operationName, modelName)
Internally, invariant will throw a new instance of MyError
with the resolved error message passed to its constructor.
invariant(false, 'First part. %s. Second part.`, 'hello')
"First path. hello. Second part."
invariant(false, 'Error message')

An exception is thrown with the "Error message" as the error message.
