A REST repository for Togglz

A simple implementation of a REST API and REST repository for Togglz implemented using Spring Boot 2.x.

The purpose of this example is to create a feature flag architecture for multiple micro services where a single service, the feature flag service, holds the state of all feature flags and individual micro services use the REST API of the feature flag service to create a local in-memory feature flag repository.

Usage

This is a proof of concept where the code base includes both the feature flag service and a dummy micro service accessing the shared feature flag service.

The feature flag service aka master

• Activated with master Spring profile
• This exposes a read only REST API for to a JDBC backed Togglz repository
• Service runs on port 8080 and exposes http://localhost:8080/features-api/v1/state used by clients
• Togglz management console is exposed on http://localhost:8080/feature-flags/index

Example micro service aka client

• Activated with client Spring profile
• This injects a cached RESTStateReposity that reads feature flags using the master REST API
• Service runs on port 8081

Note, no authentication has been implemented between master and client.
