With an intuitive UI, you can create and review your to-do lists. This project was inspired by my personal morning routine of listing three important tasks and reflecting on them briefly in the evening. I found it difficult to maintain a diary, so I created this application as a practice.

• Auto Focusing: The input field is automatically focused when the Enter key is pressed.
• Delete To-Do: A delete button appears when hovering over an item, allowing for easy deletion.
• Drag and Drop Items: To-do items can be reordered via drag and drop. If an item is dragged out of the drop zone, it returns to its original position.
• Retrospective Section: A retrospective section appears when all tasks are completed, allowing you to write brief reflections. Items in the retrospective can be listed by pressing the Enter key.
• Delete Retrospective Items: Retrospective items can be deleted.
• Auto Date Transition: The date automatically advances to the next day after 24 hours.
• Data Storage and Load: The list data is saved to localStorage and loaded when the page is reopened.

• Implemented the drag and drop feature for the list without using any libraries.
• Chose UnoCSS over TailwindCSS for a new utility-first CSS framework, leveraging its extensibility, readability, and custom features.
• Utilized the popular date formatting library date-fns.

• Framework: React
• Language: JavaScript
• Styling: UnoCSS, Iconify
• Utilities: date-fns
• Storage: localStorage

• Source Code: GitHub
• Build Tools: Vite
• Package Manager: pnpm

• Hosting and Deployment: Netlify

• Currently, data is stored in localStorage. It would be beneficial to integrate with Notion or Google Calendar in the future.
• Enable editing when clicking outside the text area of an item.
• Refactor Input and List components.
• Display data from previous dates.
• Add animation effects.
• Allow sub-tasks to be entered via the Tab key (using tree structures or recursive functions).
• Make completed lists collapsible.

• UnoCSS

  • I learned about UnoCSS while researching CSS compilation/bundling and decided to apply it. It took a considerable amount of time to configure.
  • Using attributify caused IntelliSense to be unreliable, so I ended up reporting this issue.
  • Discovered other useful services like FontShare and iconify.
  • UnoCSS seems to be more flexible than TailwindCSS, making it more suitable for large projects with established design systems. The ability to extend naming rules with regular expressions is a significant advantage.
  • While promising, the ecosystem still feels somewhat immature, with official documentation and configuration details lacking.
  • It seems to be favored by those skilled with TailwindCSS or other preset libraries for more complex functionalities.

• date-fns

  • Although I was using native Intl, I decided to familiarize myself with a date library, and chose date-fns.
  • After researching alternatives like dayjs, luxon, and moment, I found date-fns to be the most flexible and performant.
  • It's well-modularized and has a small package size, which is advantageous for bundling.
  • However, running a bundling analyzer or checking the network tab revealed a significant size impact.
  • For this project, using a library was necessary due to the potential for a calendar feature. However, for simpler date calculations, custom functions might be more efficient.

• Drag and Drop Feature

  • Studied the drag event to implement the feature without a library.
  • Styling was particularly challenging, requiring further study.
