- I have decided to use Vue.js 3 with the Composition API because it allows to create global states and reuse component logic.
- To have a consistent style guide, I have installed eslint and prettier to follow Vue style guide rules.
- For the chart component, I have used vue-chart-3 because it is a charts.js v3 wrapper written in Typescript and using Composition API for Vue 3. This way it is faster to create charts and modify charts. However, I have found that it is not doing tree-shaking so I had to lazy-import the component that was using this library because the bundle size was pretty big.
- For styling, I have used SASS (SCSS) preprocessor and BEM methodology for naming classes as I believe it allows to have styles that are scalable and maintainable.
- I have chosen [Cryptocompare API][https://min-api.cryptocompare.com/data] because the endopoins I needed were free to use without an API key or subscription.
- This app follows a reactive pattern by using the Composition API to share and manage top currencies list and currency quote selected states. I have also used it to reuse currency details component logic.
- I have divided styles by globals and mixins. Component-specific styles are declared in the corresponding Vue component.
- Components are named by prefixing the view where they belong if they are unique to that view, by 'The' if they are unique or by 'Base' if they can be used anywhere. I like this system because it allows to keep a clean and flat structure. If the application were larger, I would have may followed Atomic Design.
- I have used semantic HTML and aria attributes to have a better accessibility.
- Add date selector for choosing date range for the historical data.
- Add dark mode.
- Add unit testings with Jest.
- Add e2e tests with Cypress.
- Make accessibility checks by following WCAG.
- Add microanimations to improve user experience overall.
