Migrating from 1.x to 2.x

• Middleware and Afterware executor is removed. Therefore, no use of a executor function that takes a next argument and return the next(args)

• In middleware, instead of returning next(args), return [...args] in an array form

• In afterware, instead of returning next(args), return {result: <result to be used by next afterware>, args: <arguments to be used by next afterware>}

• Afterware callback takes result from previous afterware/target as first argument and remaining arguments with it

• Extra argument as config can be sent to involve or series. It includes the flag for throwOnMiddleware, throwOnTarget, throwOnAfterware that help in execution of the middleware/afterware/target even if there is any error that occurs in any of them, according the flags provided
