🚀 Easy to use: Declare the lists of your feature and for which context they are released.

😻 Fast feedback from users: By avoiding long-lived Git branches, you can get feedback faster from your users.

🚦 Flexibility of release: Be empowered by continuously deploying your code and deciding when/where and for who your features are released.

Getting Started

1 - Install Confeature Flag using yarn:

yarn add confeature-flag

Or npm:

npm install confeature-flag

2 - Import the dependency

const { newConfeatureFlag } = require("confeature-flag");

or

import { newConfeatureFlag } from "confeature-flag";

3 - Create the configuration which lists the features and the contexts for which they are released. This will work with a json or JavaScript object.

const configuration = `{
  "my_super_feature": {
    "release_for": ["dev", "qa", "betaTesterUser"]
  }
}`;

4 - Then create a feature flag that contains the configuration plus the initial context. This will return an object with functions generated based on the list of the features provided.

const context = "dev";
const confeatureFlag = newConfeatureFlag(configuration, context);

5.a - The feature my_super_feature will generate isMySuperFeatureReleased() function and will return its result based on the initial context.

if (confeatureFlag.isMySuperFeatureReleased()) {
  // path if the feature is released for the initial context
}

5.b - A second function is also generated for each feature which allows you to set a different context on the fly. The feature my_super_feature will generated isMySuperFeareReleasedFor(yourDifferentContext) and will return its result based on this new context.

if (confeatureFlag.isMySuperFeatureReleasedFor("betaTesterUser")) {
  // path if the feature is released for a new context
}
