Momento has announced a new feature that allows users to access Momento Cache in edge environments through an HTTP API, demonstrated with a Cloudflare worker example. Users need a Momento cache, an authentication token, and the associated HTTP endpoint to utilize this feature, which is currently available in AWS regions. The setup involves cloning example code from the Momento JavaScript SDK, configuring Cloudflare worker files, and securely storing authentication tokens as Cloudflare secrets. The provided example code demonstrates basic cache operations such as setting and retrieving data, and users can run a local development server or deploy the setup to their Cloudflare account. The company encourages users to explore advanced applications of Momento Cache in edge functions for enhanced data reliability and functionality.
