What is name validation?
The process of ensuring that the user-provided input contains only legitimate characters is known as name validation. Generally speaking, a proper name includes letters, spaces, hyphens, and apostrophes.
Why validate names?
There are several reasons to validate names:
- Accuracy: Validating names ensures that the information the user gives is accurate, which lowers the risk of system mistakes.
- Security: Name verification can assist in preventing security lapses. By ensuring that the input submitted by the user is genuine, you may limit the danger of SQL injection attacks, cross-site scripting attacks, and other vulnerabilities.
- User experience: You may enhance the user experience by validating names. Users will find a smoother and less error-prone environment.
1. Common expressions
This regular expression recognizes alphabetic characters, spaces, hyphens, and apostrophes in strings.
2. Built-in validation
This approach is comparable to the regular expression approach because it uses the match rather than the test method.
3. Libraries provided by third parties
Validator.js is a well-known library. Validator.js’ validation techniques can validate names, emails, phone numbers, and other input types.
This method uses Validator.js’s ‘isAlpha’ and ‘isLength’ methods to validate names. The isAlpha and isLength methods determine whether a string contains only alphabets and whether it has a length of 2 to 100 characters.
When developing a name validation system, it is critical to consider both the needs of your users and your specific use case. Do you work with names from other countries or only first and last names in one language? Are there any legal or formatting requirements? By responding to these questions and adapting your validation technique accordingly, you can create a seamless, error-free user experience that distinguishes your application from the competition.
