How to dynamically set an object key in typescript

Question

How do I create a function where a key of an object is dynamically set from the function

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
  return Joi.object({
    key: Joi.string()
      .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
      .required(),
  });
};

how do I make the key be the key of the object

Answer 1

Maybe you can try the following:

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
    let object: any = {};
    object[key] = Joi.string()
          .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
          .required();
    return Joi.object(object);
}

Cheers

I've been able to find a way out using the code snippet below

export const validateObjectId = (key: string = 'id'): ObjectSchema => {
  interface Obj {
    [key: string]: Object;
  }

  const object: Obj = {};

  object[key] = Joi.string()
    .regex(/^(?=[a-f\d]{24}$)(\d+[a-f]|[a-f]+\d)/i)
    .required();
  return Joi.object(object);
};
