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

In this frontend mentor challenge I had the opportunity to continue my study on the new features introduced by the Angular framework, in particular I also studied the use of Angular Animations to have a smooth transition in the result component.

Thanks to animations based on the app state I was able to add animations based on:

  • the presence of the result, in case of form submission;
  • absence of the result, in case of initial state or possible subsequent reset.
What challenges did you encounter, and how did you overcome them?

A tricky use case was the logic for the amount input to format it as a currency, with decimal digits and separators based on locales. For this purpose I've used a valueChanges observable provided by form controls: the input is treated as text but formatted each time the valueChanges observable emits. The formatting phase includes the usage of Decimal Pipe provided by Angular to format the string with decimals and separators.

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

I would love to get some feedbacks from you. Your insights would be incredibly valuable in helping me improve. Here are a few specific areas where I'd appreciate your thoughts:

  • Folder Structure Management:

How effective is the current folder structure? Are there any changes you would suggest to improve organization and maintainability?

  • State Design and Action Management:

What do you think about the design of the state and the way actions are managed? Are there any best practices or improvements you would recommend?

  • SCSS Organization:

How is the SCSS part of the application organized? Do you have any suggestions for better structuring or optimizing the SCSS?

  • Possible Improvements or Suggestions:

Do you have any general feedback or suggestions for improving the solutions I've implemented? Are there any areas where you see potential for enhancement?

Thank you so much for taking the time to review my work. Your feedback is greatly appreciated ❤️.

Happy code to everyone!! 😁

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.
