Deno as Linux systemd service. How?

Question

For reasons I don't understand, Deno is not a systemd service by default. It has an auto install script that drops the deno executable file in your /home folder. When you deno run a Typescript file using this executable, it loads up your script and them you can say goodbye to the console being used for anything else.

How do I add deno as a systemd service to Ubuntu?

Answer 1

YES! I figured it out!

Although, it would be really nice if you could help me figure out why deno only executes if you are logged in as a root user. I cannot get deno to run with sudo user.

Steps:

1. Install deno using the .sh script they provide at deno.land

2. Copy your httpServer.ts to your /home directory.

3. Tell systemd about the application by creating the service file we will be using.

4. sudo touch /etc/systemd/system/deno.service

5. Edit this recently created empty file using the template below.

[Unit]
Description=Deno 1.1.1 service
Documentation=http://deno.land
Wants=network-online.target
After=network-online.target
[Service]
Type=simple
User=user1
WorkingDirectory=/home
ExecStart=/home/user1/.deno/bin/deno run --allow-net --allow-read httpServer.ts
Restart=on-failure

[Install]
WantedBy=multi-user.target

6. Then enable and start it.

sudo systemctl enable deno

sudo systemctl start deno

7. Check status of deno service.

sudo systemctl status deno
