bivio

Bivio is a feature toggle library to be used ideally with Typescript. Powered by the Metadata Reflection API, it can be used to turn on/off your app components based on a predicate.

Installation

$ npm install bivio

Usage

Decorate the component you want to turn on/off with a predicate.

import {Predicates, FeatureToggle} from "bivio"
 
@FeatureToggle(Predicates.version("2.0.0"))
class MyModule {
    
}

Check if the predicate is valid when registering your component.

 
import {FeatureChecker} from "bivio";
 
let featureChecker = new FeatureChecker();
if (this.featureChecker.check(MyModule)) {
    //Class is valid, turn it on
} else {
    //Class is not valid, turn if off
}

Predicates

Here you can find all the predicates available, or you can write your own (it's just a function that returns a boolean).
