The dbg CLI is included with the @ephem-sh/debugger npm
package. Since it's installed as a dev dependency, run it with
npx dbg (or pnpm exec dbg, bunx dbg). For Go, Python,
and Rust projects, install the Node.js package alongside your
language-specific package to get access to the CLI.
Verify the installation
Once you have debugger installed, confirm that everything is wired up correctly.
Run your application as you normally would. debugger activates automatically in development mode.
Open a new terminal in the same project directory and run: ```command npm pnpm bun yarn live dbg status
You see session information including the framework name, port, and process ID.
