Final Project 1: A Dashboard with API Data and Filters

Build a realistic dashboard that consumes remote data, filters and transforms it for UI, and handles loading and error states with a maintainable structure.

📘 Theory

Define a Sharp Dashboard Scope Before Coding

A strong first project is focused, not oversized.

1

Pick one meaningful data set and one useful filtering experience. For example: users with search and status filters, products with category sorting, or tasks with priority views.

2

The project gets much stronger when the data model and the UI purpose are clear from the start.

Keep Raw Data, UI State, and Derived Data Separate

Dashboards become messy when those concerns are mixed together.

1

A practical structure is to store the fetched base data, the current filter state, and the visible derived list as separate concepts.

2

That makes it easier to re-render the dashboard when filters change without re-fetching unnecessarily or duplicating logic.

Build a Render Flow Instead of DOM Fragments Everywhere

A dashboard is easier to maintain when rendering follows a stable order.

1

One common pattern is: update state, compute visible items, render status messages, then render the list or cards.

2

That is much healthier than directly mutating scattered DOM nodes inside every condition and every event.

What Makes This Project Feel Professional

Polish here comes from behavior, not from adding random features.

1

Professional signals include good loading feedback, empty-state handling, readable filter logic, and a predictable response when the request fails.

2

A smaller project with clear behavior is much stronger than a larger one full of untested edge cases.

🧪 Learn by doing

Example Guided Example: Model Dashboard State Keep raw items, filters, and error state explicit before implementing rendering.

🏁 Challenges

Challenge Challenge: Build a Derived List from Filters Filter base data by search text and status without mutating the original collection.

What is this?

I'm Cristian Eslava and I sometimes build websites so both you and I can learn and experiment. culTest

I made this in February 2026 to make learning easier for my students. The idea is to learn web development by practicing and to keep expanding the project with new topics, tests and challenges.

It draws inspiration from MDN, W3Schools, CodePen, Manz and many other web development references. I wanted to combine useful theory, runnable examples, challenges and the testing system I had already built for culTest. culTest
