Notes

For the colors I decided to use the [] syntax to set the exact hex as Bootstrap thus: hover:border-[#0a58ca] text-[#fff].... You can however use Tailwind's color presets [↗].

This is one of the components that had some extra styling for transitions, I left those out.

Here is the Bootstrap base styling for all buttons:

Original Bootstrap CSS
🚫 Wrap Code📋 Copy
01: .btn {
02:     display: inline-block;
03:     font-weight: 400;
04:     line-height: 1.5;
05:     color: #212529;
06:     text-align: center;
07:     text-decoration: none;
08:     vertical-align: middle;
09:     cursor: pointer;
10:     -webkit-user-select: none;
11:     -moz-user-select: none;
12:     user-select: none;
13:     background-color: transparent;
14:     border: 1px solid transparent;
15:     padding: 0.375rem 0.75rem;
16:     font-size: 1rem;
17:     border-radius: 0.25rem;
18:     /* transition: color .15s ease-in-out,background-color .15s ease-in-out,border-color .15s ease-in-out,box-shadow .15s ease-in-out; */
19: 
20: }

The commented-out bit is what I left out.

You may have also noticed the repetition of some utility classes. Tailwind recommends creating reusable styles [↗] whenever this happens.

This can simply be a component function that takes in unique utilities as a parameter and then produces the resulting HTML element with both the common and unique utilities set as a class attribute. For example:

buttonComponent.js
🚫 Wrap Code📋 Copy
01: function buttonComponent(textContent, propString) {
02:     return `<button type="button" class="inline-block font-normal leading-normal text-center no-underline align-middle cursor-pointer select-none border-[1px] border-[solid] px-3 py-1.5 text-[1rem] rounded ${propString}">${textContent}</button>`
03: }
04: 
05: buttonComponent('Primary', 'hover:text-[#fff] hover:bg-[#0b5ed7] hover:border-[#0a58ca] text-[#fff] bg-[#0d6efd] border-[#0d6efd]')

It's ultimately up to you and your needs.
