JwtApi

Scaffold a JSON Web Token API.

Installation

Add this line to your application's Gemfile:

gem 'jwt_api'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install jwt_api

Generate your API:

$ rails g jwt_api:setup

Usage

1. Make sure that each user that needs access to the API has a JTI generated.
   1. User.first.jti = SecureRandom.uuid
2. From your Rails console run SecureRandom.hex(64) and make note of the output.
   • Sample output:

     "0086870fb04cafbaa15b110cf78352fbca75537cc90e06892e206e07c24caa33ff5f6aadf2649cafac08c4acf6a1b7527b97bfa943481c282ba2480a0a922657"
     

3. Run rails credentials:edit --environment=development (and production, staging when applicable) and set your jwt_secret environment variable.

      jwt_secret: 0086870fb04cafbaa15b110cf78352fbca75537cc90e06892e206e07c24caa33ff5f6aadf2649cafac08c4acf6a1b7527b97bfa943481c282ba2480a0a922657

4. Request a JWT at the /api/authenticate/ endpoint.
5. Include that token as a Bearer token in all other requests.
