gorollout

Fast and concurrent-safe feature flags for golang based on Redis. Inspired by the ruby rollout gem.

Installation

go get github.com/salesloft/gorollout

Usage

package main

import (
    "github.com/go-redis/redis/v7"
    rollout "github.com/salesloft/gorollout"
)

var (
    apples = rollout.NewFeature("apples")
    bananas = rollout.NewFeature("bananas")
)

func main() {
    // instantiate a feature manager with a redis client and namespace prefix
    manager := rollout.NewManager(redis.NewClient(&redis.Options{}), "rollout")

    // activate a feature
    manager.Activate(apples)

    // deactivate a feature
    manager.Deactivate(apples)

    // rollout a feature to 25% of teams
    manager.ActivatePercentage(apples, 25)

    // explicitly activate a feature for team with id 99
    manager.ActivateTeam(99, apples)

    // check if a feature is active, globally
    manager.IsActive(apples)

    // check if a feature is active for a specific team (randomize percentage disabled)
    manager.IsTeamActive(99, apples, false)

    // check multiple feature flags at once
    manager.IsActiveMulti(apples, bananas)
}

Command Line Interface (CLI)

gorollout also includes a command line interface for viewing and managing feature flags.
