Feature Flags

About

Feature flags is a software tool that enables a product team to enable or disable (aka show or hide) specific product features on-demand without the need for code modifications or new pull requests.

History

Initially Learning Resources considered integrating a third-party feature flag solution called nuxt-feature-toggle. This solution was easy to integrate and use, however it lacked the capability to pass more customized options to flagged components. This limitation along with the other future extensibility considerations led Learning Resources to implement an in-house solution that replicates the intuitive integration / usability of the nuxt-feature-toggle but with room for future extensibility and customization.
