A simple Gmail client made with Create-React-App + React-Redux, using Gmail's public Javascript API. It also uses React Router to add some routing features.

It is meant to be a simple demo of utilizing live data from a RESTful API by using React development tools. It can be useful as a starting point for anyone wanting to fork it and extend it for their own ideas of a custom JavaScript Gmail client; or simply as a reference on using client-side Javascript to consume Gmail data. It is a non-ejected Create-React-App v2 app; convenient as you can customize project configs if you need to.

How does it work?
The account sign-in and authentication process is totally managed by Gmail's secure protocols. The workflow is as follows:

• First-time users will see a landing page with a button to sign in to Gmail.
• Once successfully signed-in, Gmail will display a screen asking the user for permission to use the account in the application.
• After permission is granted, the application will load all account data and display the Inbox folder.

IMPORTANT: The application does NOT store or persist any account or user data in any way at all. It simply fetches data from Gmail's API and displays it in the browser.

Requirements:

• All Gmail API requests require an API Key and an OAuth 2.0 Client ID. You can follow these instructions to obtain those credentials. Then, store those two values in the .env file located in the root folder by replacing <YOUR_API_KEY> and <YOUR_CLIENT_ID> respectively.
