Solution retrospective


This small but really cool project has taught me a lot and helped me to practice my newly learned React skills. I've worked with class components before, but working with function components seems to be a lot cooler. The code is more concise and easy readable. When building stuff with Vanilla JS, I was used to making everything by myself, however, now that's not the case anymore. It's not that I stopped liking making things by myself, but I think that I don't have to know how to write a code that'll generate a QR code, when I can easily add that functionality in my React project. This is just the beginning, but I can surely say that I already like working with React a lot!

This is my very first React project, so if you have any suggestion or feedback, make sure to leave a comment 👨🏻‍💻 Cheers 👾

P. S. It feels so good to be back!

    Hi Ken, great job congratulations!

    Here are a few tips for improve your code:

    • you can remove the <div class="container"> because it is superfluous
    • if I insert some empty spaces or something that is not a link the qr can be downloaded anyway, I would add a control
    • after downloading the page breaks and turns blank, you could add a download message or reset everything

    Overall you did well 😁 Hope this help!

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 1st-party linked stylesheets, and styles within <style> tags.

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.
