This is a solution to the Intro component with sign up form challenge on Frontend Mentor. Frontend Mentor challenges help you improve your coding skills by building realistic projects.

Overview

I built a signup form component that validates a user's input and shows errors if they submit an invalid form. It was built using ReactJS(create-react-app) and TailwindCSS

The challenge

Users should be able to:

  • View the optimal layout for the site depending on their device's screen size
  • See hover states for all interactive elements on the page
  • Receive an error message when the form is submitted if:
    • Any input field is empty. The message for this error should say "[Field Name] cannot be empty"
    • The email address is not formatted correctly (i.e. a correct email address should have this structure: name@host.tld). The message for this error should say "Looks like this is not an email"

My process

I chose to build this project because i wanted to try something interactive rather than static components.

Started off with unstyled React components so i could focus on how data flowed. Initially i wanted each input field to keep it's own state, but it got too complex quickly so i kept every state and functionality in the form itself and passed them as props to the input fields

After testing the first input box (for first name), i turned it into a generic component where i can pass input attributes as props. I used refs to get access to the input's value but passing refs as a prop is not allowed in react, except when passed with React.forwardRef(). It was the first time i used that functionality

Once i had the components setup and working, i got to styling it and I chose TailwindCSS for their utilities based library. Their default design system had everything i needed. No stress.

When the form gets submitted, it calls a function passed as a prop from the App parent component. That way i can do something when a valid form gets submitted (like log the user in)

After that i deployed the site using surge.sh, here's a link to the project

Built with

  • Semantic HTML5 markup
  • CSS custom properties
  • Flexbox
  • Mobile-first workflow
  • React - JS library
  • TailwindCSS - CSS library
  • Surge - Static site server

What I learned

  • Learnt how to use React.forwardRef()
  • Learnt how to setup and use tailwind for a React project including optimizing for production
  • Learnt how to use Tailwind's @apply directive so that i can use tailwind's classes in my custom styles without hardcoding those values

Continued development

I would like to learn how to customize Tailwind further. While the build looks close to the proposed design, i didn't nail it as much as i wanted to. Until i start using sass.
