Overview

The challenge

Users should be able to:

  • View an age in years, months, and days after submitting a valid date through the form
  • Receive validation errors if:
    • Any field is empty when the form is submitted
    • The day number is not between 1-31
    • The month number is not between 1-12
    • The year is in the future
    • The date is invalid e.g. 31/04/1991 (there are 30 days in April)
  • View the optimal layout for the interface depending on their device's screen size
  • See hover and focus states for all interactive elements on the page
  • See the age numbers animate to their final number when the form is submitted
  • Toggle the calendar display when the calendar icon is clicked
  • Select a date from the calendar and see the date displayed in the inputs

My process

Built with

  • Semantic HTML5 markup
  • CSS custom properties
  • Flexbox
  • Mobile-first workflow
  • Tailwindcss - CSS framework
  • TypeScript
  • Redux Toolkit - Toolset for efficient Redux development
  • React - JS library
  • Vite - JS tool
  • React libraries/packages: dayjs, react-hook-form, react-redux, react-countup

What I learned

After encountering problems with create-react-app, I made the switch to Vite, which has been a much smoother experience overall. Additionally, working with TypeScript has become increasingly clear and easier for me.
