Scope

Adds a new behavior

Compatibility

• This is a breaking change

Feature description

I propose MSW, both setupWorker and setupServer throw an exception when detected being run in NODE_ENV === 'production'.

Motivation

When MSW gets to a production environment that's a mistake on the developer's end 9 times out of 10. I believe this would be a good default behavior to have to prevent this kind of mistake.

Implementation

Apart from raising an exception, this feature should also introduce an opt-out mechanism for those who explicitly wish to run MSW in production. We must still permit to run MSW anywhere the end user want but they need to explicitly state their intention. I know that a lot of teachers rely on MSW in production to teach their workshops. I want them to keep doing that without hindrance.

worker.start({ dangerouslyRunInProduction: true })
server.listen({ dangerouslyRunInProduction: true })

When the dangerouslyRunInProduction is provided and equals true, suppress the said exception.
