Hotwire Datatables with Rails. Frontend tips & tricks

Short description #

Learn how to build maintainable reactive Rails frontends

Description #

5/6 of my latest clients needed to solve the “datatables problem”: having tables (or lists) of data that can be searched, sorted, filtered, paginated, bulk and individual actions.

Datatables example

I will show my approach to creating Hotwire datatables while solving common problems.

We will cover:

Common Hotwire mistakes & best practices:

  • unnessesary declarations
  • full page reload VS frames VS streams
  • Fat VS skinny stimulus controllers
  • Bulk update via turbo streams
  • etc.

Common frontend questions:

  • When to use ViewComponents vs Partials?
  • When to use Helpers?
  • When to abstract a TailwindCSS class?
  • Should I create my own component library?
  • etc.

Common paterns:

  • Helpers I wish rails had (active_link_to, etc.)
  • Stimulus controllers every app should have (remove_element, debounce, etc.)
  • etc.

Bonus (if time allows):

  • HTML tips that will make your Hotwire journey easier.
  • Useful tools in the ecosystem (stimulus-use, stimulus-components, turbo_boost-commands, custom turbo stream actions)
