Any time we allow user input, we need form validation. We must check that the data entered is in the correct format, that it falls inside a valid data range (for example, date fields), and that it does not contain malicious code that could lead to SQL injections.

This is referred to as form validation. When you enter data, the browser and/or web server will verify that it is in the correct format and falls within the application's limits.

In order to validate a form, we must accomplish the following: Define the form's validation rules. Any errors should be saved in a state variable. If there are any errors, prevent the form from submitting.

  • Make a React app.
  • Install React Bootstrap.
  • Make a custom form component that includes validation.
  • In App.js, add a Custom Form Component.
