get system cpu temperature in javascript

Unfortunately, it is not possible to directly access the system's CPU temperature using JavaScript. However, you could use third-party libraries and tools to retrieve the temperature from the system and then use JavaScript to display it.

One such library is "systeminformation". To use this library you can install it using npm:

npm install systeminformation

2 lines

Then, you can use the following JavaScript code to retrieve the CPU temperature:

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 code uses Promises and the async/await syntax to handle asynchronous operations.

Alternatively, you could use a system monitoring tool like lm-sensors or OpenHardwareMonitor to retrieve the temperature and write a script to retrieve its readings. Then you can execute that script using child_process module in Node.js to get the temperature details in your JavaScript code.

Here is an example of how you can execute a script and get the output in JavaScript using the child_process module:

index.tsx
const { exec } = require('child_process');

exec('/path/to/script', (err, stdout, stderr) => {
  if (err) {
    console.error(`exec error: ${err}`);
    return;
  }
  console.log(`CPU temperature: ${stdout}`);
});

Replace /path/to/script with the path to your script that retrieves the CPU temperature.
