Joi object key type

Question

I have object with dynamic string keys with string values,

{
  [string]: string
}

how can I do this?

Joi.object().keys({
  [Joi.string()]: Joi.string()
})

not working :(

Answer 1

You want to use Joi.object().pattern(). From the Joi docs, this lets you provide:

A pattern that can be either a regular expression or a joi schema that will be tested against the unknown key names.

const schema = Joi.object().pattern(
    Joi.string(), Joi.string()
)
