Use case

You need a proper way to access config from your react components and custom hooks.

Compatibility

Our package currently supports apps with React >= 16.8.0. You can use this package for React and React Native Apps.

Installation

You can install this library via NPM or YARN.

NPM

npm i @blackbox-vision/react-use-config

YARN

yarn add @blackbox-vision/react-use-config

Example Usage

After reading and performing the previous steps, you should be able to import the library and use it like in this example:

1. Define the config and wrap your App in ConfigProvider:

import React from 'react';
import ReactDOM from 'react-dom';
import { ConfigProvider } from '@blackbox-vision/react-use-config';

import Header from './Header';

const config = {
  logo: 'https://xyz.com/logo.png',
};

const App = () => (
  <ConfigProvider config={config} debug={false}>
    <App />
  </ConfigProvider>
);

export default App;

2. Import the hook and consume the config part you really need:

import React from 'react';
import { useConfig } from '@blackbox-vision/react-use-config';

const Header = (props) => {
  const logoUri = useConfig(config => config?.logo);

  return (
    <div>
      <img src={logoUri} />
      {...}
    </div>
  );
};

export default Header;

Component API

The ConfigProvider component has the following props:

| Properties | Types | Default Value | Description | | ---------- | -------- | ------------- | --------------------------------------------- | | config | object | none | Property that represents the config object | | getConfig | function | none | Property that a function to load config async | | debug | boolean | false | Property that enables debug mode |

Hooks API

useConfig

The useConfig hook lets you retrieve the full config object or a specific config part using a selector.

Parameters

The hook receives the following parameters:

• selector: It's an optional function that gives you the config and let you return an specific value that will be memoized.

Return Value

If you pass the selector to the useConfig hook you'll receive an specific config item. In case you didn't, you'll only receive the fully config object.
