Next.Js Forms: All The Resources You Need To Build Amazing And Secure Forms - Articles - Pages

Dear Next.js Aficionado,

Building and handling forms in Next.js or any other framework can easily be one of the most challenging stuff you need to do.

It’s so hard because you need some experience and knowledge in multiple disciplines like UX, Cybersecurity, Back-End Development, Front-End Development, and API Building, among others.

For example, make your form look slightly long and hard to fill out, and your website users may never use it. Or put a “suspicious privacy-intruding” field, and they not only won’t send it, but they will start having a “bad feeling” about your website.

There are many security considerations also…

Most of the time, you always need to create some backend to validate and process your forms. If you don’t validate server-side users’ data before sending it to your storage or database, that’s a significant vulnerability.

So building and handling Next.js forms is so much more work than just writing some simple JSX and an API route that accepts submissions.

That’s why I created this resource-like article where I shared links to useful articles, js libraries, and services that will help you build amazing and secure forms.

Before we dig deep into the more complex stuff, let’s first review some of the React.Js and Next.js basics regarding forms.

It’s important for both security and business reasons. On the one hand, we want our forms to be secure, so malicious users can’t use them to gain access to our database or infect the website.

On the other hand, we want to receive the correct information in a valid format from our users.

Creating amazing and secure Next.Js forms that are constantly filled out and submitted takes work.

We need to plan a lot of stuff like the proper type and the number of fields, what we should validate and what we shouldn’t, and how to make them look compact and elegant, so they don’t repel our users.

I hope all the resources I collected here help you achieve your goal…

Building and handling forms can easily be one of the most challenging stuff you need to do, but you’re not alone. There is plenty of people who’ve done it the right way and shared their experience, so we can learn to do it too.
