Launch-Lever

The easiest way to manage feature toggles in JS/TS applications.

Features

• Currently only supports managing feature toggles using JSON
• Should be super fast 💨

About

launch-lever is a simple library for managing your feature toggles.

launch-lever is for you if you want:

• A simple locally managed feature toggle.
• Something so simple you don't need to know how to make network calls to use.
• Build your toggle JSON and push the launch button.

Installation

To add launch-lever to your project:

npm install launch-lever

yarn add launch-lever

Usage

launch-lever exports a class LaunchLever together with some types for Toggle.

import { Toggle, LaunchLever, isOn } from "launch-lever";

// export interface Toggle {
//   name: string;
//   description: string;
//   status: "on" | "off";
// }

export const flags: Toggle[] = [
    {
        name: "pfx_123",
        description: "A very simple test case",
        status: "on"
    },
    {
        name: "pfx_1255",
        description: "A very simple test case",
        status: "off"
    }
]

Pass your JSON to the constructor.

const { pfx_123, pfx_1255 } = new LaunchLever(flags).flags

Use your toggle names by simply checking if they're turned on with the very handy isOn function.

if(isOn(pfx_123)) {
//show some button
}
