Deploying TypeScript services

Deploying a single service

(coming soon)

Deploying multiple services using the process manager pup

The process manager pup is a tool that can be used to run multiple services at once without having to manually start each service. It also makes it easy to manage the running services.

Installing pup

Install pup using the following command:

deno install -Afr https://deno.land/x/pup/pup.ts

Configuring pup

In your project’s root directory, create a file called pup.jsonc with the following contents:

{
  "services": [
    {
      "name": "service1",
      "command": "deno run --allow-net --allow-env service1.ts",
      "env": {
        "SERVICE_NAME": "service1",
        "NATS_URL": "nats://localhost:4222",
        "NATS_USER": "service",
        "NATS_PASSWORD": "service"
      }
    },
    {
      "name": "service2",
      "command": "deno run --allow-net --allow-env service2.ts",
      "env": {
        "SERVICE_NAME": "service1",
        "NATS_URL": "nats://localhost:4222",
        "NATS_USER": "service",
        "NATS_PASSWORD": "service"
      }
    }
  ]
}

Running pup

Run pup using the following command:

pup -c pup.jsonc run

This will start the pup runner. To start the services, run the following command:

pup -c pup.jsonc start all

Tip

If you want to have a service starting immediately after the runner starts, you can add "autostart": true to that service’s configuration.

To stop the services, run the following command:

pup -c pup.jsonc stop all

Tip

You can also stop a single service by specifying its name instead of all.

You can get the status of the services using the following command:

pup -c pup.jsonc status

Tip: Running NATS through pup

You can even run NATS through pup. Just add the following service to your pup.jsonc file:

{
  "name": "nats",
  "command": "nats-server -c <path-to-config-file>",
  "env": {}
}

You can find more information about pup on their documentation page.
