Confeature Flag 🍯


A sweet feature flag for JavaScript & TypeScript.


**🚀 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

```javascript

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.

```javascript

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.

```javascript

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.

```javascript

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.

```javascript

if (confeatureFlag.isMySuperFeatureReleasedFor("betaTesterUser")) {

  // path if the feature is released for a new context

}

```
