@fusionauth/cli

@fusionauth/cli (v1.2.4) is a command-line tool for interacting with FusionAuth, an OIDC/OAuth authentication server. It enables downloading, uploading, and managing email templates, lambdas, and themes. This fork specifically fixes compatibility with Node.js 22, as the original package broke under that version. It is written in TypeScript and distributed as an npm package. Maintenance appears minimal (rare releases). Differentiators include watch functionality for live theme/email updates and environment variable support for API key and host.
