Deno: Deno as a service in Linux.

Created on 25 Jun 2020 · 4Comments · Source: denoland/deno

Hey guys. Thanks for the awesome.

Bellow is a unit file I've created to run deno as a service in Linux. This way it restarts itself automatically in case of a crash. As you can see, it's pretty simple.

Are there specfic signals that can be sent to deno in order to stop, reload, start at runtime?

Take a look

/etc/systemd/system/deno.service

[Unit]
Description=Deno 1.1.1 service
Documentation=http://deno.land
After=network.target

[Service]
Type=simple
PIDFile=/run/deno.pid
# Typescript App Default Install directory
WorkingDirectory=/home
# Deno runtime Default Install directory
ExecStart=/home/user1/.deno/bin/deno run --allow-net --allow-read httpServer.ts
# On failer, wait 60 seconds before auto-restarting.
RestartSec=60
# Auto-restart on failure.
Restart=on-failure

[Install]
WantedBy=multi-user.target

Running Deno instance of the app.

Enable Deno - Works
sudo systemctl enable deno

Start Deno - Works
sudo systemctl start deno

Stop Deno - Works
sudo systemctl stop deno

Reload Deno - Does not work.
sudo systemctl reload deno

@suchislife801 did you confuse systemctl reload for systemctl restart?

systemctl restart - Restarts the process.
systemctl reload - Sends a signal (can't remember which at the back of my hand) to your process which you can use to reload configuration process, the process should stay running.
