JWTEasy

JWTEasy is a simple wrapper for the JWT gem (see versions below) that hopes to make generating and consuming various types of JSON web tokens a little easier.

Note: Currently only supports plain, EXP and NBF tokens with HMAC HS256 encryption.

Generating a plain token without encryption might look something like:

token = JWTEasy.encode(id: 'some-identifying-information')

You'd likely want to configure things before though:

# config/initializers/jwt_easy.rb
JWTEasy.configure do |config|
 config.expiration_time  = 3_600
 config.secret           = ENV['JWT_EASY_SECRET']
 config.algorithm        = JWTEasy::ALGORITHM_HMAC_HS256
end

Of course you're able to consume tokens just as easily:

JWTEasy.decode(token).id #=> 'some-identifying-information'

For both EXP and NBF claims, you're able to specify the leeway to be used when decoding tokens:

JWTEasy.configure do |config|
 config.leeway = 30 # seconds
end

Add this line to your application's Gemfile:

gem 'jwt_easy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jwt_easy

This gem's version numbers don't track that of the JWT gem, if you require support for a specific JWT gem version, you need to specify the correct version for this gem.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
