I have a function to execute a process:
static async runTest() { await process.exec(`start ${currentDir}/forward.py`); }
runTest();
The python script will continue to run until it's killed, which I don't know how to do at the moment. So in short, I want to kill this process manually at some point. How I would I do this? Thank you!
The exec return value is a child-process object and you can kill it anytime by calling the .kill() function. For more info, you can refer to this
https://nodejs.org/api/child_process.html
I demonstrated the kill function using a simple timeout.
const { exec } = require('child_process');
let childprocess = exec('python a.py', (error, stdout, stderr) => {
if (error) {
console.error(`error: ${error.message}`);
return;
}
if (stderr) {
console.error(`stderr: ${stderr}`);
return;
}
console.log(`stdout:\n${stdout}`);
});
setTimeout(() => { //Example killing
childprocess.kill()
}, 2000);
