Here are the steps for performing password validation in React JS using Joi schema:
Import the 'joi' module using the syntax: import Joi from 'joi';
Define a schema for the password validation, which includes the validation rules for the password. For example, you could use the following code to define a simple schema that checks for a minimum password length of 6 characters:
const passwordSchema = Joi.object({
password: Joi.string().min(6).required(),
});
function validatePassword(password) {
const { error } = passwordSchema.validate({ password });
if (error) {
return error.details[0].message;
}
return null;
}
function PasswordInput() {
const [password, setPassword] = useState('');
const [error, setError] = useState('');
function handlePasswordChange(event) {
setPassword(event.target.value);
setError(validatePassword(event.target.value));
}
return (
<div>
<label>Password:</label>
<input type="password" value={password} onChange={handlePasswordChange} />
{error && <div className="error">{error}</div>}
</div>
);
}
In this example, the state 'error' will be set to the error message returned by the validatePassword function, which will be displayed below the password input field when it is not null.
