What I think and why I think it.

The Making of Mendeleev

June 1, 2018

Around November of 2017, I thought about embarking on a new project in order to sharpen my web development skills. I wanted to create a useful and interesting project.

Because I was taking chemistry in school and had a life-long love of science, I decided to create an interactive periodic table.

At first I was using vanilla HTML/CSS and jQuery. However, I soon realized that this was beyond sub-optimal. In an effort to maximize development speed and pick up a Javascript framework, I decided to learn Vue.js.

Game Plan

Instead of diving headfirst into my endeavor, I watched Traversy Media’s “Vue.js 2.0 in 60 Minutes” to gain a working knowledge of Vue.js.

I also found a great JSON file that contained information about all of the elements. I planned to use this to display my information.

Later in the development of my web app, I would find a few more open-source projects that graciously did the grunt work for me. I used Periodic Table, another data set for elements, to display additional information that the JSON file did not include. I also leveraged atomic-bohr-model to display an atomic model of selected elements. I’m planning on implementing my own atomic models in the future but this project serves its purpose well.

In honor of Dmitri Mendeleev, Russian chemist and creator of the original periodic table, I decided to name my project “Mendeleev.”

Development Experience

While developing my web app, I heavily relied on the official documentation. For a few more esoteric problems, I used StackOverflow.

The creation of Mendeleev was not always smooth sailing. Sometimes I would run into issues that took multiple days to solve. Eventually, I would be able to solve my issue and gain a better understand of how Vue.js operated. Running into roadblocks is always a little bit frustrating. However, I knew that I would eventually be able to understand how to approach the problem and solve it.

At times during the development process, I felt like I wasn’t making very good progress or was forgetting to implement certain features. I had to figure out a method of keeping organized so I decided to use Trello to track my tasks. Trello greatly improved my perceived and actual productivity. It allowed me to keep track of features I needed to implement, bugs I needed to fix, and changes I needed to consider.

Because the scope of my project was much bigger than anything I had undertaken in the past, it forced me to find a way to track tasks. This was a very positive change in my development workflow and will allow me to tackle even larger projects in an orderly, methodical fashion.

While in the beginning stages of the project I used jQuery to handle some animation and DOM lookup. I decided to fully embrace modern Javascript and quickly refactored all of my jQuery-dependent code. I was using Flexbox and CSS Grid anyhow so support for older browsers wasn’t a big concern. jQuery was just extra bloat that I didn’t need to ship.

Feature wise, the periodic table is very simple. Hover over an element to reveal a card containing general information about the element and an atomic model of the element. Click on an element to be taken to a comprehensive profile of the selected element.

I’m not completely happy with the look of Mendeleev just yet. Disregarding some design inconsistencies, I would consider the aesthetic of Mendeleev passible. There’s plenty of room to improve in this regard. I’m satisfied with the font selection and color pallette, though.

I chose to use Roboto Condensed for its modern design and capability to cram a bunch of information into small amounts of space. It’s a condensed font after all.

I selected colors from the Tailwind CSS color pallette for its vibrant, friendly colors.

Future Considerations

As a progress in my journey as a web developer, I intend Mendeleev to progress with me. In the future, I would like add search functionality to the periodic table, find or create a more performant atomic model library, and improve the design of the project.


The creation of Mendeleev was an incredible learning experience for me. It allowed me to learn Vue.js, which makes the creation of web apps much easier. Additionally, the breadth of the project forced me to organize my tasks and plan features using Trello. The creation of my web app also allowed me to make a few small contributions to open-source projects that were immensely useful.
