The Vanilla JavaScript SDK by Frigade, suitable for any JavaScript environment including Node.js, has been significantly simplified following user feedback, enhancing the API and models for easier management of Flow lifecycles, such as marking flows and steps as completed. The SDK now includes global event handlers to facilitate application actions as users progress through flows, allowing state changes to be logged and acted upon. As it forms the basis for all of Frigade's JavaScript-based SDKs, further investments and developments in this SDK are anticipated in the coming months.
