Momento

Prerequisites

• winglang
• Momento account and API key (see Getting started with Momento)

Installation

npm i @winglibs/momento

Usage

bring cloud;
bring momento;

let token = new cloud.Secret("momento-key");
let cache = new momento.Cache(token: token);

new cloud.Function(inflight () => {
  cache.set("key", "value");
  log(cache.get("key"));
});

To deploy an application with Momento resources using Terraform, you will need to set the MOMENTO_API_KEY environment variable to a valid super-user API key on the machine running terraform apply.

You will also need a valid Momento token (super-user token or fine-grained access token) with permissions for performing any data operations on the cache(s) that can be used by the application. You can set the secret by running wing secrets -t tf-aws main.w. You are responsible for rotating the secret as needed.

See the Momento documentation for more information about creating API keys.
