setup

Install the Playwright Chromium browser and verify it can launch on your system.

Usage

csp-analyser setup

This command takes no options or arguments.

What it does

The setup command runs two steps:

1. Install browser binary: downloads Playwright's bundled Chromium using npx playwright install chromium. This does not require root/sudo.
2. Verify launch: attempts to launch the browser headlessly and immediately close it, confirming that all required system libraries are present.

If step 2 fails, the CLI detects your platform and prints targeted instructions for installing the missing system dependencies.

Platform-specific handling

The setup command detects your OS and Linux distribution to provide the right fix commands when system dependencies are missing.

Debian / Ubuntu

npx playwright install-deps chromium

This installs all required shared libraries automatically (requires sudo).

Arch Linux

Playwright does not officially support Arch, so install-deps is not available. Install dependencies manually:

# Common Chromium deps
sudo pacman -S nss alsa-lib at-spi2-core cups libdrm mesa libxkbcommon

# Or use the AUR package
yay -S playwright

# Find which package provides a specific missing library
pacman -F libXmissing.so

Fedora / RHEL

npx playwright install-deps chromium

macOS / Windows

No additional system dependencies are typically needed. The browser binary from step 1 is self-contained.

When to re-run

Run csp-analyser setup again if:

• You see errors about a missing browser or missing shared libraries when running crawl or interactive
• You upgraded Node.js or Playwright to a new major version
• You moved to a different machine or container

The CLI also checks for a working browser before every crawl and interactive command. If the check fails, it prints a message directing you to run setup.
