如何扩展 Joi 模式？

Question

我有一个名为用户的 joi 模式

const user = {
  firstName: Joi.string()
    .min(2)
    .max(50)
    .required()
    .label('First Name'),
  lastName: Joi.string()
    .min(3)
    .max(50)
    .required()
    .label('Last Name'),
  email: Joi.string()
    .allow('')
    .email({ minDomainAtoms: 2 })
    .max(100)
    .label('Email Address'),
}

我还有一个叫主人

const ownerSchema = {
  firstName: Joi.string()
    .min(2)
    .max(50)
    .required()
    .label('First Name'),
  lastName: Joi.string()
    .min(3)
    .max(50)
    .required()
    .label('Last Name'),
  email: Joi.string()
    .allow('')
    .email({ minDomainAtoms: 2 })
    .max(100)
    .label('Email Address'),
  number: Joi.string()
    .regex(/[0-9]/)
    .length(10)
    .required()
    .label('Phone Number'),
  dateOfBirth: Joi.date(),

  kycDetails: Joi.array()
    .items(schemaKyc)
    .required(),
  bankDetails: Joi.array()
    .items(schemaBank)
    .required(),
  licenceDetails: Joi.array()
    .items(schemaLicence)
    .required(),
  insuranceDetails: Joi.array()
    .items(schemaInsurance)
    .required()
};

如您所见，两者具有三个共同字段，我希望能够在所有者中使用用户架构，并且每当我对用户进行更改时，我希望它也反映在所有者中。

Answer 1

只需 spread user 里面的 ownerSchema:

const ownerSchema = {
    ...user,
    /* owner specific fields goes here */
};

Answer 2

您可以使用object.keys([schema])，其中

Sets or extends the allowed object keys where:

schema - optional object where each key is assigned a joi type object. If schema is {} no keys allowed. If schema is null or undefined, any key allowed. If schema is an object with keys, the keys are added to any previously defined keys (but narrows the selection if all keys previously allowed). Defaults to 'undefined' which allows any child key.

示例：

const base = Joi.object().keys({
    a: Joi.number(),
    b: Joi.string()
});
// Validate keys a, b and c.
const extended = base.keys({
    c: Joi.boolean()
});
