101# 📬 Newsletter Subscription App — Storyblok
This is a web application that allows users to subscribe to newsletters that are focussed on different topics. The web app has two pages which are:
1. [Subscription Page](http://localhost:5173/subscription) which allows users to fill a subscription form with basic personal details and select newsletter categories
2. [Subscription List Page](http://localhost:5173/subscription/list) which allows users to view all submitted subscriptions and filter subscriptions by category

## 🔧 Things to Improve
Here is a list of things that I would like to improve but couldn't due to time constraints:
- Add end to end tests with `Cypress`
- Add caching for the categories to prevent frequent database queries as that dataset would not change often
- Use a proper localization tool that can automatically manage translations
- Add visual feedback for loading and success/failure states
- Improve the UI rendering for the categories a customer has subscribed to on the subscription list page
- Use toasts or a proper notification library instead of using `alert()`
- Add a proper UI for visual feedback when there was an error fetching categories on the subscription and subscription list pages
- Add a not found page for visual feedback when a route that does not exist is accessed
