We have to install refine's support packages for React Table and React Hook Form. We are using Tailwind Heroicons for our icons, the Day.js library for time calculations and Recharts library to plot our charts for KPI data.

Well, I haven't reviewed the code, I just checked package.json and I'll suggest you to ditch moment.js Even the creator recommends ditching it. Dayjs is a fantastic alternative. Source: almost 2 years ago
This may sound a bit general but we can't forget about well-tought code. If we are using a lot of external dependencies, we can check if there aren't many lighter alternatives. Example? Some people are still using moment.js for date formatting. Why not use a lightweight 2kb alternative instead? Writing clean, organized and maintainable code won't give us a huge score boost but we are trying to save every byte of... - Source: dev.to / almost 2 years ago
I think Date.now() creates a string that is the number of milliseconds since 1 January 1970 UTC, and since it is UTC you can account for the timezone automatically however you format it for the user. For example, dayjs. Source: about 2 years ago

This, but I still use dayjs as a date helper library. It's tiny and internally, it uses the native browser APIs to deal with timezones, it just makes it slightly more useful API surface. Source: about 2 years ago

Let’s take a look at an example implementation of import maps. In this tutorial, we will learn how to import a bare module like dayjs without the use of a bundler. - Source: dev.to / about 2 years ago
You may want to take a look at dayjs. It’s 6.5kb to date-fns’ 162kb and shares the same api as moment allowing it to be a much easier package to integrate into an existing moment setup. Granted if you need added functionality you need to use the plugins too so they add to bundle size a little, however 90% of the time the base package is enough. Source: about 2 years ago
