JWT VS Clearance

To authenticate our users, we need to add jwt gem to our Gemfile

jwt is a Ruby implementation of the RFC 7519 OAuth JSON Web Token standard. bcrypt is a Ruby binding for the OpenBSD bcrypt() password hashing algorithm.

ruby-jwt is fairly easy to use on it's own without Devise. You might try that first and only add Devise if needed.

Generally speaking, the larger the application, the more internal and external services it has to talk to. External services usually have their own way of authenticating and authorizing third party API calls. With internal systems however, organisations prefer to use JWT tokens because of their inherent flexibility and versatility. A sample JWT based handshake between 2 rails applications using ruby-jwt would look like this -

Interesting. What's the difference between this and the standard ruby-jwt? https://github.com/jwt/ruby-jwt

jwt - encoding and decoding jwt oauth

Decoding JWTs is simple whit the help of an already implemented solution. In this section, I'll be using the ruby-jwt.

https://github.com/thoughtbot/clearance It is simple and good. You can also customize it easily.

Clearance has been better for most of my projects. Its got a cleaner implementation that Devise, and comes with a generator that will optionally dump all of the basic routes and views into the standard locations which you can then edit at will.

I tend to suggest Clearance for Rails apps that need a more focused toolset. It may not do everything that Devise does, but it definitely works well with Rails 7. https://rubygems.org/gems/clearance/versions/2.5.0

I've found a much simpler/cleaner authentication gem is Clearance. Devise does just about everything, but Clearance is more opinionated so out of the box it does more of what you normally want.

...because some folks prefer clearance to devise! :-D

Clearance is a Rails authentication with email & password. It is intended to be small, simple, and well-tested. It has opinionated defaults but is intended to be easy to override. 3,321 stars by now
