Create Calender heatmap in react like Github (from scratch)

You must have seen those cool user activity heatmaps that shows the number of commits you’ve done over time using your github account. This has been a really crucial part of our journey.

Today I was able to create the same calender heatmap (without any packages) like GitHub and Leetcode under 30 minutes, and I’ve also recorded a simple video on that starting from scratch.

I’ve got an amazing response on twitter and I Hope you’ll like this video as well.

In case you want to see more of these, I’ve a whole playlist on react machine coding and building components from scratch. You can head over to @indgeek on YouTube.
