Getting Started with APIMATIC Calculator

Introduction

Simple calculator API hosted on APIMATIC

Building

The generated code depends on a few Ruby gems. The references to these gems are added in the gemspec file. The easiest way to resolve the dependencies, build the gem and install it is through Rake:

• Install Rake if not already installed: gem install rake
• Install Bundler if not already installed: gem install bundler
• From terminal/cmd navigate to the root directory of the SDK.
• Invoke: rake install

Alternatively, you can build and install the gem manually:

• From terminal/cmd navigate to the root directory of the SDK.
• Run the build command: gem build apimatic_calculator.gemspec
• Run the install command: gem install apimatic_calculator-1.0.0.gem

Installation

The following section explains how to use the apimatic_calculator ruby gem in a new Rails project using RubyMine™. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

1. Starting a new project

Close any existing projects in RubyMine™ by selecting File -> Close Project. Next, click on Create New Project to create a new project from scratch.

Next, provide TestApp as the project name, choose Rails Application as the project type, and click OK.

In the next dialog make sure that the correct Ruby SDK is being used (>= 2.6 and < 3.1) and click OK.

2. Add reference of the gem

In order to use the Tester gem in the new project we must add a gem reference. Locate the Gemfile in the Project Explorer window under the TestApp project node. The file contains references to all gems being used in the project. Here, add the reference to the library gem by adding the following line: gem 'apimatic_calculator', '1.0.0'

3. Adding a new Rails Controller

Once the TestApp project is created, a folder named controllers will be visible in the Project Explorer under the following path: TestApp > app > controllers. Right click on this folder and select New -> Run Rails Generator....

Selecting the said option will popup a small window where the generator names are displayed. Here, select the controller template.

Next, a popup window will ask you for a Controller name and included Actions. For controller name provide Hello and include an action named Index and click OK.

A new controller class named HelloController will be created in a file named hello_controller.rb containing a method named Index. In this method, add code for initialization and a sample for its usage.

Test the SDK

To run the tests, navigate to the root directory of the SDK in your terminal and execute the following command:

rake
