Installation

$ npm install --save @mathdoy/toggle

Note: This package povides the core functionality for toggle, but you might not to want to install it alone. If you are writing an application that will run react you should install @mathdoy/toggle-react next to this one. If you want to use it for your backend node server, we have an restify middleware that you should install @mathdoy/toggle-restify

import { createToggle } from "@mathdoy/toggle";

const toggle = createToggle({
  prefix: "X-FEAT-",
  features: {
    logo: false,
    foo: false,
  },
});

// Register new feature into Toggle
toggle.register("foo", true);

// Look if the feature is enabled or not return Boolean
toggle.isEnabled("foo"); // true

// Remove feature from registry
toggle.unregister("foo");

Using it with React

$ npm install --save @mathdoy/toggle @mathdoy/toggle-react

import React from "react";
import ReactDOM from "react-dom";
import { createToggle } from "@mathdoy/toggle";
import { ToggleProvider } from "@mathdoy/toggle-react";
import "./index.css";
import App from "./App";

const toggle = createToggle({
  features: {
    logo: false,
    foo: true,
    // ...features
  },
});

ReactDOM.render(
  <ToggleProvider toggle={toggle}>
    <App />
  </ToggleProvider>,
  document.getElementById("root")
);

Then in your components files

import React, { Component } from "react";
import { Toggle } from "@mathdoy/toggle-react";
import FeatureDisable from "./FeatureDisable";

// ...

class App extends Component {
  render() {
    return (
      <div className="App">
        <header className="App-header">
          <Toggle isEnabled="logo" disableComponent={<FeatureDisable />}>
            <img src={logo} className="App-logo" alt="logo" />
          </Toggle>
          <p>
            Edit <code>src/App.js</code> and save to reload.
          </p>
          <a
            className="App-link"
            href="https://reactjs.org"
            target="_blank"
            rel="noopener noreferrer"
          >
            Learn React
          </a>
        </header>
      </div>
    );
  }
}

export default App;

You can also bind toggle into your component props with withToggle

import {
  ToggleProvider,
  withToggle,
  togglePropType,
} from "@mathdoy/toggle-react";

// ...

class App extends Component {
  static propTypes = {
    toggle: togglePropType.isRequired,
  };

  render() {
    const { toggle } = this.props;

    return (
      <div className="App">{toggle.isEnabled("foo") && <div>foo</div>}</div>
    );
  }
}

export default withToggle(App);
