Harness Feature Flags has introduced support for an open-source Node.js SDK, offering organizations the ability to utilize feature flags in server-side applications and services that use JavaScript across their stack. This development allows organizations to implement feature flags with consistent performance and support akin to other Harness SDKs, thereby facilitating streamlined feature rollouts and management. Node.js, known for its popularity and extensive package ecosystem, is a preferred server-side language for many organizations, prompting Harness to offer this dedicated SDK. Users familiar with other Harness SDKs will find the same patterns and use cases applicable with the Node.js SDK, and they can refer to the Node.js SDK Reference for guidance on implementation. Successfully deploying a feature flag involves both ensuring the SDK functions correctly and integrating the flag within the codebase, with additional resources available through the in-app wizard or Getting Started documentation.
