Project Automation

asd up / asd down

Project automations from asd.yaml

Start project

bash

$ asd up           # Default environment
$ asd up --dev     # Development environment
$ asd up --staging # Staging environment
$ asd up --prod    # Production environment

Stop project

bash

$ asd down         # Stop and cleanup

Uses asd.yaml for project configuration. Flags: --dev, --staging, --prod

Configuration (asd.yaml)

Define services and automation tasks in your project root:

asd.yaml

# asd.yaml
network:
  services:
    app:
      dial: "127.0.0.1:3000"
      tunnelPrefix: "myapp"
      path: "/"
    api:
      dial: "127.0.0.1:4000"
      tunnelPrefix: "myapp"
      path: "/api"

automation:
  dev:
    - npm run dev
  test:
    - npm run test
  build:
    - npm run build

network.services

Define services with their local addresses, tunnel prefixes, and URL paths.

automation

Define tasks that run with asd up --dev etc.

Frequently Asked Questions

What's the difference between up and start?

Both start a service, but 'up' also exposes it via tunnel for external access. 'start' runs the service locally only. Use 'up' when you need to share or access remotely, 'start' for local-only development.

Can I use both command syntaxes interchangeably?

Yes! Both 'asd caddy start' and 'asd start caddy' are equivalent. Use whichever feels more natural to you.

What environment flags are available for asd up?

You can use --dev, --staging, or --prod to run environment-specific automation tasks defined in your asd.yaml file.

How do I see all running services?

Run 'asd net' to open the interactive TUI showing all services, their status, and public URLs.
