Joi validation of array

Question

trying to validate that an array has zero or more strings in one case and that it has zero or more objects in another , struggling with Joi docs :(

validate: {
          


        

Answer 1

Joi.array().items() accepts another Joi schema to use against the array elements. So an array of strings is this easy:

Joi.array().items(Joi.string())

Same for an array of objects; just pass an object schema to items():

Joi.array().items(Joi.object({
    // Object schema
}))
