I've created following Schema for validation using Joi:
const createProfileSchema = Joi.object().keys({
username: Joi.string()
.required()
.message("username is required")
.empty()
.message("username is not allowed to be empty")
.min(5)
.message("username must be greater than 5 characters")
.max(20)
.message("username must be less than 5 characters")
});
But it throws the flowing error:
Cannot apply rules to empty ruleset or the last rule added does not support rule properties
4 | username: Joi.string()
5 | .required()
> 6 | .message("username is required")
| ^
7 | .empty()
8 | .message("username is not allowed to be empty")
9 | .min(5)
Actually I want to set a custom message for every individual error case.
You can try something like this with latest version of @hapi/joi package.
const Joi = require("@hapi/joi");
const createProfileSchema = Joi.object().keys({
username: Joi.string()
.required()
.empty()
.min(5)
.max(20)
.messages({
"string.base": `"username" should be a type of 'text'`,
"string.empty": `"username" cannot be an empty field`,
"string.min": `"username" should have a minimum length of {#limit}`,
"string.max": `"username" should have a maximum length of {#limit}`,
"any.required": `"username" is a required field`
})
});
const validationResult = createProfileSchema.validate(
{ username: "" },
{ abortEarly: false }
);
console.log(validationResult.error);
