transformParameters & normalizeParameters

[L1lith]

TransformParameters:
Allows you to modify your parameters after they are sanitized before they are passed to call. It could accept either the synchronous return, a promise to await to the output, or the call of a provided callback. It would merge the returned value with the existing ones. This could be useful for something like this

transformParameters: (parameters, next) => {
     bcrypt.hash(parameters.password, (error, hash) =>{
          if (error) return next(error)
          next({hash})
     })
}

NormalizeParameters
Almost exactly the same as transformParameters except it would happen before sanitation so you could normalize it before it's sanitized.

normalizeParameters: parameters => ({email: parameters.email.toLowerCase()})
