'exit' 事件

• code <number> 如果其正常退出，则为退出码。
• signal <string> 造成进程被终止的信号的名称（例如 'SIGHUP'）。

类似于 cluster.on('exit') 事件，但特定于此工作进程。

import cluster from 'node:cluster';

if (cluster.isPrimary) {
  const worker = cluster.fork();
  worker.on('exit', (code, signal) => {
    if (signal) {
      console.log(`worker was killed by signal: ${signal}`);
    } else if (code !== 0) {
      console.log(`worker exited with error code: ${code}`);
    } else {
      console.log('worker success!');
    }
  });
}const cluster = require('node:cluster');

if (cluster.isPrimary) {
  const worker = cluster.fork();
  worker.on('exit', (code, signal) => {
    if (signal) {
      console.log(`worker was killed by signal: ${signal}`);
    } else if (code !== 0) {
      console.log(`worker exited with error code: ${code}`);
    } else {
      console.log('worker success!');
    }
  });
}

• code <number> The exit code, if it exited normally.
• signal <string> The name of the signal (e.g. 'SIGHUP') that caused the process to be killed.

Similar to the cluster.on('exit') event, but specific to this worker.

import cluster from 'node:cluster';

if (cluster.isPrimary) {
  const worker = cluster.fork();
  worker.on('exit', (code, signal) => {
    if (signal) {
      console.log(`worker was killed by signal: ${signal}`);
    } else if (code !== 0) {
      console.log(`worker exited with error code: ${code}`);
    } else {
      console.log('worker success!');
    }
  });
}const cluster = require('node:cluster');

if (cluster.isPrimary) {
  const worker = cluster.fork();
  worker.on('exit', (code, signal) => {
    if (signal) {
      console.log(`worker was killed by signal: ${signal}`);
    } else if (code !== 0) {
      console.log(`worker exited with error code: ${code}`);
    } else {
      console.log('worker success!');
    }
  });
