Coding Fonts Playground

Day 24 of #30DaysOfStartingUp

In this issue, I will share one lesson I learned today.

Storytime!

Yesterday, I wrote a tutorial about Retool, demoing a process to rebuild the Google Fonts website within 30 minutes. Retool’s Twitter account picked it up and shared it! I was pleased with the project and continued to hack around it today, even though I was not supposed to.

Seeing what Google Fonts API and Retool can do together, I came up with an idea to create a “Coding Fonts Playground” to help programmers pick coding fonts easily. My secret goal is to make a traffic magnet to promote my product and newsletters because my last growth hack project has been successful.

I had most of the functionalities done from yesterday’s tutorial piece. All I need to do is to:

  1. Filter the table to show monospaced fonts only.

  2. Add a code preview window.

I blazed through #1 by altering the data transformer in Retool:

I get stuck at #2. I wanted the code preview to look very fancy with syntax highlighting and color theme “Cobalt,” like what I had in my other project CSS Mono microsite:

I need to use javascript like prism.js to achieve syntax highlighting; however, I found out Retool blocked all javascript in the iFrame component. I have to write a custom Retool component using react.js to perform syntax highlighting. 

I entertained the direction for two hours until dinner time when I paused my work to cook. Cooking is a great time to think. It hits me: I just need a code preview window. Syntax highlighting adds flair, but it is hardly necessary. I could get #2 done in a few minutes, but instead, I spent hours!

After dinner, I wrapped up #2 with nothing fancy but <pre> <code> tags and simple CSS:

“If users like a particular font, they may want to download it.” I thought. So I added another requirement to the app feature list:

3. Add download fonts button

It surprised me how little it takes to add such a crucial feature. I just add a button to open this link:

https://fonts.google.com/download?family={{encodeURIComponent(table_fonts.selectedRow.data.family)}}

So there it is my story: what I spent most of my day doing is essentially worthless, and what I spent 5 mins doing makes the app become useful. It is a real-life example of the 80/20 rule 80% of the value to the customer comes from 20% of the effort, and vice versa!

What I could do better next time: prioritize and put my effort into high return over investment features. Because it is a fun mini-project, I let go of product management and work rather linearly. 

I was also overly stubborn on getting the syntax highlighting to work. I started to implement it because it was easy to do last time, thinking it would be low-hanging fruit. I forgot to re-adjust my plan when I found out it was not easy because of how Retool handles iFrame. I got lost in my train of thought and was mindlessly fixated to get it to work.

Have you had similar moments? Let me know your story!
