Validating a submit request with javascipt

Java Script provides a way to validate form's data on the client's computer before sending it to the web server. First let us see how to do a basic form validation.

In the above form, we are calling validate() to validate data when onsubmit event is occurring.

Dan Pastori has over 10 years experience as a full stack developer.

When you aren't finding Dan working on building a farm using Arduinos, catch him at the beach or hiking in the National Parks.

If any of these requests fail, we will get a (400 Bad Request) response back from the server and bad data will not be entered into our system!

We can catch these errors as well and display them to the user.

Vue JS (Vue.js) is definitely hands down the best front end Javascript framework out there.This way we can flag the field as invalid and display custom text if needed. Laravel has some sweet tools to make this really easy: Validation – Laravel – The PHP Framework For Web Artisans.Sometimes a field can be invalid for many reasons, so having a variable for the text helps a ton. Honestly there are a million different ways to implement your validations, so pick what you feel most comfortable with. First, define what valid data looks like for each entity: 1. First we will make a new request, according to the documentation. This is where we define the validations for the incoming data.This will at least stop a whole bunch of invalid data requests and enhance UX when adding a new cafe.First, I usually add a validations object to the data returned from the component.

Since we have our validation created, we need to add the request to the controller route.
