[英]pm2 + KOA process.send is undefined
I am trying to accomplish the "graceful start" with pm2, but somehow my process.send is always undefined.我试图用 pm2 完成“优雅的开始”,但不知何故我的 process.send 总是未定义。
I am using esm module and start my application with yarn start我正在使用esm模块并使用yarn start启动我的应用程序
I am logging the process.send, but somehow it is always undefined.我正在记录 process.send,但不知何故它总是未定义。
app.listen(port, () => {
console.log('process.send', process.send);
console.log(`Server running on port ${port}`);
});
Where could be the problem?问题可能出在哪里?
Thanks and best regards谢谢和最好的问候
I had the same issue with an application using npm start
as script in pm2 .我在pm2 中使用
npm start
作为脚本的应用程序遇到了同样的问题。
I guess pm2 needs to start the application with an internal child process in node to make process.send('ready')
work.我猜pm2需要使用节点中的内部子进程启动应用程序以使
process.send('ready')
工作。
Changing to "script": "./dist/main.js"
for pm2 made it work for me.更改为
"script": "./dist/main.js"
为PM2使得它为我工作。
So maybe changing your config and application to something like this:因此,也许将您的配置和应用程序更改为如下所示:
module.exports = {
apps: [
{
name: 'myApp',
script: './dist/main.js',
time: true,
listen_timeout: 10000,
env: { environment: 'production', NODE_ENV: 'production', },
}
],
};
(Depending of the output from your build) (取决于构建的输出)
