Error: pattern must be a RegExp using Joi framework nodejs-CodePudding

I need to accept a mobile number as an input for example 97255555555. I need the user to enter first sign and then only digits.

  const LoginValidation = (data) => {
    const schema = Joi.object({
        phone: Joi.string().required().regex("/^([ ]\d*)?$/"),
        passwordUser: Joi.string().required(),
    });
    return schema.validate(data);
  };
module.exports.LoginValidation = LoginValidation;

But I'm facing following issue while validating with Joi framework: UnhandledPromiseRejectionWarning: Error: regex must be a RegExp.

CodePudding user response：

let re = RegExp("/^([ ]\d*)?$/";
const LoginValidation = (data) => {
    const schema = Joi.object({
        phone: Joi.string().required().regex(re),
        passwordUser: Joi.string().required(),
    });
    return schema.validate(data);
  };

It's just saying that rather than expecting a regex string. It's expecting a regex object.

I fixed this by changing to pattern instead of regex

  const LoginValidation = (data) => {
    const schema = Joi.object({
        phone: Joi.string().required().pattern(/^([ ]\d*)?$/),
        passwordUser: Joi.string().required(),
    });
    return schema.validate(data);
  };
module.exports.LoginValidation = LoginValidation;
