Rails ajax comparison (fetch, Rails.ajax, axios, @rails/request.js, Turbo)

Rails ajax comparison (fetch, Rails.ajax, axios, @rails/request.js, Turbo)

I wrote this gist because I felt that the Rails documentation was lacking a description of ajax requests.

📌 Options for ajax request

There are various ways to send ajax requests in Rails.

  1. Browser default Fetch API
  2. Rails.ajax (No Official docs and request for docs)
  3. http client like axios
  4. @rails/request.js 👈 I'm using this one now !

Action Mailbox: The Missing Manual

This is all you really need to know in order to make Action Mailbox work in development.

  1. Fire up ngrok http 3000 and make note of your subdomain for steps 3 and 8.
  2. Create a Mailgun account because they offer sandbox addresses; grab your domain from the Dashboard.
  3. Go into Receiving and create a catch-all route pointing to: https://XXX.ngrok.io/rails/action_mailbox/mailgun/inbound_emails/mime
  4. Add your Mailgun API key to your credentials:

Tailwind CSS best practices

Utility classes

  1. When writing a string of multiple utility classes, always do so in an order with meaning. The "Concentric CSS" approach works well with utility classes (i.e,. 1. positioning/visibility 2. box model 3. borders 4. backgrounds 5. typography 6. other visual adjustments). Once you establish a familiar pattern of ordering, parsing through long strings of utility classes will become much, much faster so a little more effort up front goes a long way!

  2. Always use fewer utility classes when possible. For example, use mx-2 instead of ml-2 mr-2 and don't be afraid to use the simpler p-4 lg:pt-8 instead of the longer, more complicated pt-4 lg:pt-8 pr-4 pb-4 pl-4.

  3. Prefix all utility classes that will only apply at a certain breakpoint with that breakpoint's prefix. For example, use block lg:flex lg:flex-col lg:justify-center instead of block lg:flex flex-col justify-center to make it very clear that the flexbox utilities are only applicable at the

Cheat Sheet: Simple Authentication in Rails 5 with has_secure_password

Cheat Sheet: Simple Authentication in Rails 6 with has_secure_password

The goal of this cheatsheet is to make it easy to add hand-rolled authentication to any rails app in a series of layers.

First the simplest/core layers, then optional layers depending on which features/functionality you want.
