Prompt Title: Arduino IoT API Hook.

Human: you are a developer assistant that is tasked with writing an app that connects to arduino iot service via API call. You are given a Java Script code that accomplishes this task. The Java script is as follows: var IotApi = require('@arduino/arduino-iot-client'); var rp = require('request-promise'); async function getToken() { var options = { method: 'POST', url: 'https://api2.arduino.cc/iot/v1/clients/token', headers: { 'content-type': 'application/x-www-form-urlencoded' }, json: true, form: { grant_type: 'client_credentials', client_id: 'CLIENT_ID', client_secret: 'CLIENT_SECRET', audience: 'https://api2.arduino.cc/iot' } }; try { const response = await rp(options); return response['access_token']; } catch (error) { console.error("Failed getting an access token: " + error) } } async function run() { var client = IotApi.ApiClient.instance; // Configure OAuth2 access token for authorization: oauth2 var oauth2 = client.authentications['oauth2']; oauth2.accessToken = await getToken(); var api = new IotApi.DevicesV2Api(client) api.devicesV2List().then(devices => { console.log(devices); }, error => { console.log(error) }); } run(); Write a custom react js hook using the code above to implement this api call into react JS app

ChatGPT:

To create a custom React JS hook that uses the code above to make an API call to the Arduino IoT service, you can follow these steps:

1. Install the necessary packages:

   • @arduino/arduino-iot-client
   • request-promise

   You can use the following command in your terminal to install them:

   arduinoCopy code
   npm install @arduino/arduino-iot-client request-promise
   

2. Create a new file called useArduinoIoT.js.

3. In this file, import the necessary modules:

   javascriptCopy code
   import { useState, useEffect } from 'react';
   import IotApi from '@arduino/arduino-iot-client';
   import rp from 'request-promise';
   

4. Create a new function called useArduinoIoT:

   javascriptCopy code
   function useArduinoIoT() {
     const [devices, setDevices] = useState([]);
     const [isLoading, setIsLoading] = useState(true);
     const [error, setError] = useState(null);
   
     useEffect(() => {
       async function fetchData() {
         try {
           const accessToken = await getToken();
           const client = IotApi.ApiClient.instance;
           const oauth2 = client.authentications['oauth2'];
           oauth2.accessToken = accessToken;
           const api = new IotApi.DevicesV2Api(client);
           const devices = await api.devicesV2List();
           setDevices(devices);
           setIsLoading(false);
         } catch (error) {
           setIsLoading(false);
           setError(error);
         }
       }
   
       fetchData();
     }, []);
   
     return { devices, isLoading, error };
   }
   

5. Define the getToken() function:

   javascriptCopy code
   async function getToken() {
     const options = {
       method: 'POST',
       url: 'https://api2.arduino.cc/iot/v1/clients/token',
       headers: { 'content-type': 'application/x-www-form-urlencoded' },
       json: true,
       form: {
         grant_type: 'client_credentials',
         client_id: 'CLIENT_ID',
         client_secret: 'CLIENT_SECRET',
         audience: 'https://api2.arduino.cc/iot'
       }
     };
   
     try {
       const response = await rp(options);
       return response['access_token'];
     } catch (error) {
       console.error('Failed getting an access token: ' + error);
     }
   }
   

6. Export the useArduinoIoT function:

   javascriptCopy code
   export default useArduinoIoT;
   

7. In your React component, import the useArduinoIoT hook and use it to fetch the devices from the Arduino IoT service:

   javascriptCopy code
   import React from 'react';
   import useArduinoIoT from './useArduinoIoT';
   
   function App() {
     const { devices, isLoading, error } = useArduinoIoT();
   
     if (isLoading) {
       return <div>Loading...</div>;
     }
   
     if (error) {
       return <div>Error: {error.message}</div>;
     }
   
     return (
       <div>
         {devices.map((device) => (
           <div key={device.id}>{device.name}</div>
         ))}
       </div>
     );
   }
   
   export default App;
   

   This component will render a list of device names once the API call is complete. While the data is being fetched, it will display a loading message. If an error occurs, it will display an error message.

Human: Rewrite the code in Typescript

ChatGPT:

Sure! Here's the rewritten code in TypeScript:

typescriptCopy code
import { useState, useEffect } from 'react';
import IotApi from '@arduino/arduino-iot-client';
import rp from 'request-promise';

interface Device {
  id: string;
  name: string;
  // Add more properties here if necessary
}

interface ArduinoIoTData {
  devices: Device[];
  isLoading: boolean;
  error: Error | null;
}

async function getToken(): Promise<string> {
  const options = {
    method: 'POST',
    url: 'https://api2.arduino.cc/iot/v1/clients/token',
    headers: { 'content-type': 'application/x-www-form-urlencoded' },
    json: true,
    form: {
      grant_type: 'client_credentials',
      client_id: 'CLIENT_ID',
      client_secret: 'CLIENT_SECRET',
      audience: 'https://api2.arduino.cc/iot',
    },
  };

  try {
    const response = await rp(options);
    return response['access_token'];
  } catch (error) {
    console.error('Failed getting an access token: ' + error);
    throw error;
  }
}

function useArduinoIoT(): ArduinoIoTData {
  const [devices, setDevices] = useState<Device[]>([]);
  const [isLoading, setIsLoading] = useState<boolean>(true);
  const [error, setError] = useState<Error | null>(null);

  useEffect(() => {
    async function fetchData() {
      try {
        const accessToken = await getToken();
        const client = IotApi.ApiClient.instance;
        const oauth2 = client.authentications['oauth2'];
        oauth2.accessToken = accessToken;
        const api = new IotApi.DevicesV2Api(client);
        const devices = await api.devicesV2List();
        setDevices(devices);
        setIsLoading(false);
      } catch (error) {
        setIsLoading(false);
        setError(error);
      }
    }

    fetchData();
  }, []);

  return { devices, isLoading, error };
}

export default useArduinoIoT;

The changes I made include:

• Adding type annotations for the Device and ArduinoIoTData interfaces.
• Adding a return type for the getToken function.
• Adding type annotations for the state variables and the useArduinoIoT function.
• Adding a throw statement in the catch block of the getToken function to re-throw the error and propagate it up to the calling code.
• Exporting the useArduinoIoT function at the end.

Human: Write a new declaration (.d.ts) file containing `declare module @arduino/arduino-iot-client

ChatGPT:

Sure! Here's a possible declaration file for @arduino/arduino-iot-client:

typescriptCopy code
declare module '@arduino/arduino-iot-client' {
  export class ApiClient {
    authentications: { [key: string]: any };
    constructor();
    static instance: ApiClient;
  }

  export class DevicesV2Api {
    constructor(apiClient?: ApiClient);
    devicesV2List(): Promise<Device[]>;
  }

  export interface Device {
    id: string;
    name: string;
    // Add more properties here if necessary
  }
}

This declaration file declares the @arduino/arduino-iot-client module, which exports the ApiClient and DevicesV2Api classes, as well as the Device interface.

The ApiClient class has an authentications property, which is an object containing the authentication options for the client. It also has a static instance property, which returns a shared instance of the client.

The DevicesV2Api class has a constructor that accepts an optional apiClient parameter, which defaults to the shared instance of the ApiClient. It also has a devicesV2List method, which returns a Promise that resolves to an array of Device objects.

The Device interface defines the properties of a device, such as its id and name. You can add more properties to this interface if necessary, based on the actual schema of the API response.
