The npm-user-validate package is used to validate npm usernames. It ensures that usernames conform to the rules and guidelines set by npm, such as length and character restrictions.

What are npm-user-validate's main functionalities?

Username Validation

This feature allows you to validate a given npm username to check if it meets the npm username requirements. The function returns a boolean indicating whether the username is valid.

const validate = require('npm-user-validate');

const username = 'valid-username';
const isValid = validate(username);
console.log(isValid); // true or false

Custom Validation Messages

This feature provides detailed error messages when a username does not meet the validation criteria. The `validate.errors` array contains specific reasons why the username is invalid.

const validate = require('npm-user-validate');

const username = 'invalid username';
const isValid = validate(username);
if (!isValid) {
  console.log(validate.errors); // Array of error messages
}
