Using Google Drive as a CMS

This article details a method for using Google Drive's API to manage website content, eliminating the need for a traditional CMS. We'll cover the technical implementation, server-side caching to optimize API usage, and address potential security concerns. A complete solution, including an npm package, Git repository, and Docker image, is available.

Why Use Google Drive as a CMS?

Traditional CMS solutions like WordPress introduce complexity: new platforms to learn, increased security risks, and template management overhead. This approach leverages Google Drive, a familiar tool for many teams, to simplify content management. This is particularly beneficial when non-technical personnel need editing access.

Prerequisites

Before starting, familiarize yourself with the following resources:

• GitHub repository
• NPM package
• Docker image
• Heroku demo

Google Drive API Authentication: Service Accounts

Instead of OAuth, which requires user-specific authorization, we use Google service accounts. A service account acts as a dedicated API user with its own email address and permissions. Granting this account access to specific Drive files or folders provides granular control and enhances security. Creating a service account is straightforward through the Google Cloud Platform Console (detailed steps are in the GitHub repository).

Interacting with the Google Drive API

Using a modified Node.js quickstart sample, we authenticate the service account via jwtClient. The crucial difference is handling authentication using a service account's credentials, stored securely on the server and excluded from version control.

Node.js Server-Side Implementation

The code runs server-side to protect sensitive credentials. Functions like getDoc(id, skipCache = false) fetch and return the HTML content of a Google Doc, handling image caching to avoid hotlinking. Similarly, getSheet(id, range) retrieves data from Google Sheets, transforming it into a JSON array. The API can also handle listing files, importing from Google Slides, and downloading other file types.

Caching for Performance and API Limits

Caching is crucial for managing Google Drive API rate limits. Every fetched file version is cached, minimizing API calls. Image URLs within Google Docs are also cached, eliminating hotlinking and improving performance. This approach ensures API usage remains within limits and provides a faster user experience.

Express.js Integration

The Drive API is wrapped in an Express.js REST service, creating a proxy layer that handles caching and protects credentials. Routes like /getDoc fetch and return data, simplifying client-side interaction.

Docker Deployment

The Express server can be deployed using Docker, simplifying the deployment process. A Dockerfile is provided, and a pre-built image is available on Docker Hub.

Enhanced Security with NGINX and Google OAuth (Optional)

For enhanced security on internal websites, NGINX can be used as a reverse proxy, integrating with Google OAuth for single sign-on. This adds an extra layer of authentication before requests reach the Express server.

Conclusion

This Google Drive-based CMS offers a lightweight, flexible solution, ideal for internal sites with moderate traffic and teams already using Google Drive. Its key advantages include ease of use for non-technical users, reduced complexity compared to traditional CMS solutions, and improved security. The approach is particularly suitable for single-page applications or scenarios where minimizing API requests is paramount.
