Describe the problem you are trying to fix (provide as much context as possible)

const baseStringSchema = Joi.string().trim();
const keepWhitespaceSchema = baseStringSchema.trim(false);

This is needed because I want to trim every string by default, but allow sometimes.

Which API (or modification of the current API) do you suggest to solve that problem ?

• string.trim()
• Just adding enabled?: boolean option to the existing trim() implementation will solve above problem, like the existing string.truncate([enabled]) method.

Are you ready to work on a pull request if your suggestion is accepted ?
