Today, we’re excited to announce version 1.1.0 of the Twitch CLI which features a beta version of RFC 0015 - Mock Twitch API via CLI. With this release, we are matching the current functionality of the Twitch API except for a few endpoints, which are noted in the documentation for the new feature.
Additionally, we’ve added all remaining EventSub subscription types so it is now topic-complete, meaning you can test EventSub easily and without an online connection.
To get started, see GitHub - twitchdev/twitch-cli: The official Twitch CLI to make developing on Twitch easier., which includes installation and usage instructions.
