Object validation in JavaScript can be tedious if you don't have a good framework in place. In this post, we'll use the Array.reduce method to make...
For further actions, you may consider blocking this person and/or reporting abuse
Note: the name and password length validation can be done with HTML alone. No need for JavaScript. See the minlength attribute.
Good point - but i d like to think that this is also for server side validation. My rule of thumb: validate on the frontend for comfort , validate on the server for security .
My thought exactly.
HTML and JavaScript validation can be bypassed easily using the Developer Tools. If you plan on sending any data from the frontend to the server-side, you have to perform layered validation.
With the HTML then the JavaScript and finally the server-side. If they get past the first two, unless there is a hole in the server-side validation they are not getting past that.
Better still use a whitelist and deny any input that is not on this list.
Frontend form validation is not done for security, it's for user experience.
Backend validation is security, ideally frontend validation should be so good that non-malign users will mostly never hit those backend validation errors.
Imho frontend and backend validations serve completely different purposes and cannot directly be compared.
Frontend form validation is a mixture of good user experience with security in mind.
Respectfully, frontend validation has absolutely zero to do with security.
Thanks very clear
I like this one a lot, thanks for sharing Nick!
Platform crossover! 💪
I like this! You should flesh out the idea a bit more and publish an npm package 😃
Excellent example 👍 Thanks
