Package Script Writer

If you're spinning up Umbraco CMS instances, this handles the entire installation process through a CLI tool called psw. It generates and runs installation scripts with database setup, admin credentials, and optional package installation all in one command. The key trick is the `-d` flag, which actually generates a proper installation script instead of just a basic dotnet run command. Works non-interactively with sensible defaults, supports SQLite for quick testing or SQL Server for production, and can bundle packages like uSync or Umbraco.Forms with specific versions. Most useful when you need repeatable Umbraco setups or want to automate dev environment creation without clicking through the installer.

Package Script Writer (psw)

Generate and run Umbraco CMS installation scripts using the psw CLI tool.

Workflow

Check if PSW CLI is installed:
```
psw --version
```
If command not found, the .NET tools path may not be in PATH. Try:
- Linux/Mac: export PATH="$PATH:$HOME/.dotnet/tools" && psw --version
- Windows: %USERPROFILE%\.dotnet\tools\psw --version

If not installed, install it:

dotnet tool install --global PackageScriptWriter.Cli

Then run the psw command (see below)

Non-Interactive Usage (Claude Code)

This is the command to use:

export PATH="$PATH:$HOME/.dotnet/tools"
psw -d -n ProjectName -s ProjectName -u --database-type SQLite --admin-email admin@test.com --admin-password SecurePass1234 --auto-run

Run this with run_in_background: true since Umbraco is a long-running web server.
