An easy-to-use testing application called myapp:
const fs = require("fs");
const json_encode = require('json_encode');
//simulating a real error
var wrong;
var test = json_encode(wrong);
//TypeError: Cannot read property 'replace' of undefined at json_encode...
To save the error log for myapp as myapp_error.log from the command line, I use:
node myapp2.js > myapp_error.log 2>&1
//myapp_error.log is generated and the logged error can be viewed
Now, I need to achieve the same when starting myapp as a service in /etc/systemd/system, like so:
systemctl start myapp
The service (which has been tested and is running successfully) includes:
[Unit]
Description=myapp
[Service]
ExecStart=/path/to/myapp/myapp.js
Restart=my_username
User=nobody
Group=www-data
Environment=PATH=/usr/bin:/usr/local/bin
Environment=NODE_ENV=production
WorkingDirectory=/path/to/myapp
[Install]
WantedBy=multi-user.target
I have attempted:
ExecStart=/path/to/myapp/myapp.js > myapp_error.log 2>&1and also tried:
systemctl start myapp > myapp_error.log 2>&1myapp_error.log in /etc/systemd/system)
