Solution retrospective


What are you most proud of, and what would you do differently next time?

I'm proud of pushing through the production grade build of this form with shadcn/ui and react-hook-form. There were plenty of opportunities to take short cuts, but I'm glad I stuck with it and made a high quality build.

What challenges did you encounter, and how did you overcome them?

I thought this was going to be an easier form to build than it turned out to be. Because there was not submit button I need to use the watch method, which I hadn't done before. I need to customize the errors and also coerce the types with zod.

What specific areas of your project would you like help with?

If anyone has feedback on better ways to leverage react-hook-form with zod and shadcn/ui I am all for it.

    • I know the inputs take in numbers, but you should set the input type to text to get rid of the up and down arrows.

    • I'm not sure why you put default values for the bill, tip %, and number of people. When a site first loads, the app should look like it has never been touched by a user before.

    • Also, maybe try to add in some logic where if the user has already selected a tip % and they click that same percentage again, it gets deselected.

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
