API Samples

This directory contains a simple Sinatra web app illustrating how to use the client in a server-side web environment.

It illustrates a few key concepts:

Using Google Sign-in for authentication.
Using the googleauth gem to request incremental authorization as more permissions are needed.

Setup

Create a project at https://console.developers.google.com
Go to the API Manager and enable the Drive and Calendar APIs
Go to Credentials and create a new OAuth Client ID of type 'Web application'
- Use http://localhost:4567/oauth2callback as the redirect URL
- Use http://localhost:4567 as the JavaScript origin

Additional details on how to enable APIs and create credentials can be found in the help guide in the console.

For convenience, application credentials can be read from the shell environment or placed in a .env file.

After setup, your .env file might look something like:

GOOGLE_CLIENT_ID=479164972499-i7j6av7bp2s4on5ltb7pjXXXXXXXXXX.apps.googleusercontent.com
GOOGLE_CLIENT_SECRET=JBotCTG5biFWGzXXXXXXXXXX

To start the server, run

ruby app.rb

Open http://localhost:4567/ in your browser to explore the sample.
