How to create api clients for your application? What is a better way to encapsualte interactions with third APIs? My answer is act_as_api_client.

Let's assume you have a typical Rails or any ruby application and want to play around with an API, Github for example. See the Usage section to find how to use existing preconfigured API's and encapsulate all logic inside APIClient classes.

At the moment i experiment in order to make api clients behavior very similiar to ActiveRecord models, so out of the box most of the clients support these methods: find, where, delete, update, find_by, create, update


Add this line to your application's Gemfile:

gem 'act_as_api_client'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install act_as_api_client


Folder for clients:

Create a folder in your app for examples api_clients inside your lib directory. This will be the place where you will keep all... api clients.

Create API client class:

For example you want to fetch and update Github repositoties, then you class may have a form like this:

class GithubClient < ApiClient
  act_as_api_client for: :github

In case you want to provide and use authorization token for Github:

class GithubClient < ApiClient
  act_as_api_client for: :github,
                    with: {
                      token: <your_token>

btw, all values from with hash will be availabe in tour clients as instance variable @options

Use it:

Let's fetch all repositories from Rails organization:

github_client =

github_client.find_by(organization: 'rails')
github_client.where('rails', per_page: 100)
