useBeeConfig

This document provides a detailed description of the useBeeConfig.ts file, which implements a custom React hook to manage the configuration of a bee device using the IBeeConfig interface. This hook leverages state management and side effects to fetch and store configuration data.

Overview

The useBeeConfig hook is designed to interact with a bee device configuration by fetching it based on a provided id. This hook makes use of React hooks such as useState, useEffect, and useCallback to manage state and side effects efficiently.

Interface

The hook uses the following imported interface:

import { IBeeConfig } from "shared/interfaces";

IBeeConfig Definition

Property	Type	Description
useMqtt	boolean	Indicates if MQTT is used.
mqttBroker	string	The MQTT broker URL.
mqttChannel	string	The MQTT channel name.
device	string	The identifier of the device.

Dependencies

• React Hooks:
  • useState for state management.
  • useCallback to memoize the fetch function.
  • useEffect to fetch configuration on component mount.

import { useCallback, useEffect, useState } from "react";

Hook Implementation

eort function useBeeConfig(id: number) {
  const [beeConfig, setBeeConfig] = useState<IBeeConfig>({
    useMqtt: false,
    mqttBroker: "",
    mqttChannel: "",
    device: "",
  });

  /**
   * **Fetch bee config**
   *
   * Fetches the bee configuration using the provided `id`.
   */
  const fetchBeeConfig = useCallback(async () => {
    const fetchedBeeConfig = await window.kweenb.methods.getBeeConfig(id);
    setBeeConfig(fetchedBeeConfig);
  }, []);

  useEffect(() => {
    fetchBeeConfig();
  }, []);

  return { beeConfig };
}

Description

Function: useBeeConfig

• Parameters:

  • id: number - The identifier for the bee configuration.

• State:

  • beeConfig: IBeeConfig - Initial state is set to default values (useMqtt: false, empty mqttBroker, mqttChannel, and device).

• Fetch Function: fetchBeeConfig

  • Purpose: To asynchronously fetch and update the beeConfig using window.kweenb.methods.getBeeConfig.
  • Attributes:
    • Wrapped with useCallback to prevent unnecessary re-creation of the function.

• Effect Hook:

  • Executes fetchBeeConfig on component mount to ensure beeConfig is fetched when the component using this hook renders.

Return Value

• Returns an object containing:
  • beeConfig: The current configuration object.

Usage Example

Here's an example of how to use the useBeeConfig hook within a functional component:

import React from "react";
import { useBeeConfig } from "./useBeeConfig";

const BeeConfigComponent = ({ id }) => {
  const { beeConfig } = useBeeConfig(id);

  return (
    <div>
      <h1>Bee Device Configuration</h1>
      <ul>
        <li>
          <strong>Use MQTT:</strong> {beeConfig.useMqtt ? "Yes" : "No"}
        </li>
        <li>
          <strong>MQTT Broker:</strong> {beeConfig.mqttBroker}
        </li>
        <li>
          <strong>MQTT Channel:</strong> {beeConfig.mqttChannel}
        </li>
        <li>
          <strong>Device:</strong> {beeConfig.device}
        </li>
      </ul>
    </div>
  );
};

eort default BeeConfigComponent;
