get system cpu temperature in celsius in javascript

Unfortunately, JavaScript does not provide direct access to the system information required to obtain CPU temperature. However, it is possible to use a third-party library or make a request to an API that provides this information.

One option is to use the Open Hardware Monitor API. This API provides a way to get the CPU temperature and other system information through an HTTP request to a local server. Here's an example code that shows how to fetch the CPU temperature using this API:

index.tsx
const url = 'http://localhost:8085/data.json';
const options = { mode: 'cors'};
fetch(url, options)
  .then(response => response.json())
  .then(data => {
    const cpuTemperature = data.Children[0].Children[1].Value;
    console.log(`CPU Temperature: ${cpuTemperature}°C`);
  })
  .catch(error => console.error(error));

Note that to use this API you need to install and run the Open Hardware Monitor software on your system. Additionally, you'll need to configure the HTTP server to enable remote access to the API.

Another option is to use a library like Systeminformation.js. This library provides a way to get various system information, including CPU temperature, using a simple API. Here's an example code that shows how to fetch the CPU temperature using Systeminformation.js:

index.tsx
const si = require('systeminformation');
si.cpuTemperature()
  .then(data => {
    console.log(`CPU Temperature: ${data.main}°C`);
  })
  .catch(error => console.error(error));

Note that this library requires to be installed via npm.
