const NewUser = Joi.object()
  .keys({
    email: Joi.string()
      .email()
      .example("[email protected]"),
    name: Joi.string().example("john doe"),
    username: Joi.when("email", {
      is: Joi.exist(),
      then: Joi.string().required(),
      otherwise: Joi.optional()
    }).example("johndoe"),
    password: Joi.when("email", {
      is: Joi.exist(),
      then: Joi.string().required(),
      otherwise: Joi.optional()
    }).example("password"),
    "first-name": Joi.string()
      .allow(null)
      .example("john"),
    "communication-email": Joi.string()
      .allow(null)
      .example("[email protected]"),
    "phone-number": Joi.number()
      .allow(null)
      .example(9898989898),
    "avatar-s3-key": Joi.string()
      .allow(null)
      .example("ace/2018-12/89a3fa9c-0b79-4140-b0ef-d1a35ea0b733/dog4.jpeg"),
    "last-name": Joi.string()
      .allow(null)
      .example("doe"),
    "dont-login": Joi.boolean()
      .allow(null)
      .example(true),
    "avatar-url": Joi.string()
      .uri()
      .allow(null)
      .example(
        "https://thumbor-stg.assettype.com/ace/2018-12/89a3fa9c-0b79-4140-b0ef-d1a35ea0b733/dog4.jpeg"
      ),
    "login-phone-number": Joi.string().example("+919898989898"),
    otp: Joi.string()
      .when("login-phone-number", {
        is: Joi.exist(),
        then: Joi.required(),
        otherwise: Joi.optional()
      })
      .when("email", {
        is: Joi.exist(),
        then: Joi.required(),
        otherwise: Joi.optional()
      })
      .example("12345"),
    metadata: Joi.object()
      .example({ "favorite-fruit": "papaya" })
      .meta({ swagger: { deprecated: true } }),
    active: Joi.boolean().example(true)
  })
  .xor("otp", "username", "password")
  .or("login-phone-number", "email");

For payload:
{
    "email":"[email protected]",
    "otp": "913676"
}
Response:
{
    "message": "\"body.username\" is required,\"body.password\" is required"
}

username and password was initially to be mandatory, but when I have otp, username+password can be optional and vice versa. it can also allow all the three fields.

Wouldn't it work with a simple .and('username', 'password').or('username', 'otp')?

If email exists user can signup/login via otp or username+password

• when otp exists in the request body, u+p can be optional
• when u+p is in request body, otp can be optional
• email+otp, email+u+p is also allowed

.and('username', 'password').or('username', 'otp') doesn't work. I tried the below code.

const NewUser = Joi.object()
  .keys({
    email: Joi.string()
      .email()
      .example("[email protected]"),
    name: Joi.string().example("john doe"),
    username: Joi.when("email", {
      is: Joi.exist(),
      then: Joi.string().required(),
      otherwise: Joi.optional()
    }).example("johndoe"),
    password: Joi.when("email", {
      is: Joi.exist(),
      then: Joi.string().required(),
      otherwise: Joi.optional()
    }).example("password"),
    "login-phone-number": Joi.string().example("+919898989898"),
    otp: Joi.string()
      .when("login-phone-number", {
        is: Joi.exist(),
        then: Joi.required(),
        otherwise: Joi.optional()
      })
      .when("email", {
        is: Joi.exist(),
        then: Joi.required(),
        otherwise: Joi.optional()
      })
      .example("12345"),
    metadata: Joi.object()
      .example({ "favorite-fruit": "papaya" })
      .meta({ swagger: { deprecated: true } }),
    active: Joi.boolean().example(true)
  })
  .or("login-phone-number", "email")
  .and("username", "password")
  .or("username", "otp");

I believe if you use and/or for the u + p and u + otp you shouldn't use when anymore. Have you tried removing the when?
