Vibium Browser Automation — CLI Reference

The vibium CLI automates Chrome via the command line. The browser auto-launches on first use (daemon mode keeps it running between commands).

vibium go <url> && vibium map && vibium click @e1 && vibium map

Core Workflow

Every browser automation follows this pattern:

1. Navigate: vibium go <url>
2. Map: vibium map (get element refs like @e1, @e2)
3. Interact: Use refs to click, fill, select — e.g. vibium click @e1
4. Re-map: After navigation or DOM changes, get fresh refs with vibium map

Binary Resolution

Before running any commands, resolve the vibium binary path once:

1. Try vibium directly (works if globally installed via npm install -g vibium)
2. Fall back to ./clicker/bin/vibium (dev environment, in project root)
3. Fall back to ./node_modules/.bin/vibium (local npm install)

Run vibium --help (or the resolved path) to confirm. Use the resolved path for all subsequent commands.

Windows note: Use forward slashes in paths (e.g. ./clicker/bin/vibium.exe) and quote paths containing spaces.

Command Chaining

Chain commands with && to run them sequentially. The chain stops on first error:

vibium go https://example.com && vibium map && vibium click @e3 && vibium diff map

When to chain: Use && for sequences that should happen back-to-back (navigate → interact → verify). Run commands separately when you need to inspect output between steps.

When NOT to chain: Don't chain commands that depend on parsing the previous output (e.g. reading map output to decide what to click). Run those separately so you can analyze the result first.

Common Patterns

Ref-based workflow (recommended for AI)

vibium go https://example.com
vibium map
vibium click @e1
vibium map  # re-map after interaction

Verify action worked

vibium map
vibium click @e3
vibium diff map  # see what changed

Read a page

vibium go https://example.com && vibium text

Fill a form (end-to-end)

vibium go https://example.com/login
vibium map
# Look at map output to identify form fields
vibium fill @e1 "user@example.com"
vibium fill @e2 "secret"
vibium click @e3
vibium wait-for-url "/dashboard"
vibium screenshot -o after-login.png

Scoped map (large pages)

vibium map --selector "nav"        # Only map elements in <nav>
vibium map --selector "#sidebar"   # Only map elements in #sidebar
vibium map --selector "form"       # Only map form controls

Semantic find (no CSS selectors needed)

vibium find --text "Sign In"           # → @e1 [button] "Sign In"
vibium find --label "Email"            # → @e1 [input] placeholder="Email"
vibium click @e1                       # Click the found element
vibium find --placeholder "Search..."  # → @e1 [input] placeholder="Search..."
vibium find --testid "submit-btn"      # → @e1 [button] "Submit"
vibium find --alt "Company logo"       # → @e1 [img] alt="Company logo"
vibium find --title "Close"            # → @e1 [button] title="Close"
vibium find --xpath "//a[@href='/about']"  # → @e1 [a] "About"

Authentication with state persistence

# Log in once and save state
vibium go https://app.example.com/login
vibium fill "input[name=email]" "user@example.com"
vibium fill "input[name=password]" "secret"
vibium click "button[type=submit]"
vibium wait-for-url "/dashboard"
vibium storage-state -o auth.json

# Restore in a later session (skips login)
vibium restore-storage auth.json
vibium go https://app.example.com/dashboard

Extract structured data

vibium go https://example.com
vibium eval "JSON.stringify([...document.querySelectorAll('a')].map(a => ({text: a.textContent.trim(), href: a.href})))"

Check page structure without rendering

vibium go https://example.com && vibium a11y-tree

Multi-tab workflow

vibium tab-new https://docs.example.com
vibium text "h1"
vibium tab-switch 0

Annotated screenshot

vibium screenshot -o annotated.png --annotate

Inspect an element

vibium attr "a" "href"
vibium value "input[name=email]"
vibium is-visible ".modal"

Save as PDF

vibium go https://example.com && vibium pdf -o page.pdf

Eval / JavaScript

vibium eval is the escape hatch for any DOM query or mutation the CLI doesn't cover directly.

Simple expressions — use single quotes:

vibium eval 'document.title'
vibium eval 'document.querySelectorAll("li").length'

Complex scripts — use --stdin with a heredoc:

vibium eval --stdin <<'EOF'
const rows = [...document.querySelectorAll('table tbody tr')];
JSON.stringify(rows.map(r => {
  const cells = r.querySelectorAll('td');
  return { name: cells[0].textContent.trim(), price: cells[1].textContent.trim() };
}));
EOF

JSON output — use --json to get machine-readable output:

vibium eval --json 'JSON.stringify({url: location.href, title: document.title})'

Timeouts and Waiting

All interaction commands (click, fill, type, etc.) auto-wait for the target element to be actionable. You usually don't need explicit waits.

Use explicit waits when:

• Waiting for navigation: vibium wait-for-url "/dashboard" — after clicking a link that navigates
• Waiting for content: vibium wait-for-text "Success" — after form submission, wait for confirmation
• Waiting for element: vibium wait ".modal" — wait for a modal to appear
• Waiting for page load: vibium wait-for-load — after navigation to a slow page
• Waiting for JS condition: vibium wait-for-fn "window.appReady === true" — wait for app initialization
• Fixed delay (last resort): vibium sleep 2000 — only when no better signal exists (max 30s)

All wait commands accept --timeout <ms> (default varies by command).

Ref Lifecycle

Refs (@e1, @e2) are invalidated when the page changes. Always re-map after:

• Clicking links or buttons that navigate
• Form submissions
• Dynamic content loading (dropdowns, modals)

Global Flags

Tips

• All click/type/hover/fill actions auto-wait for the element to be actionable
• All selector arguments also accept @ref from vibium map
• Use vibium map before interacting to discover interactive elements
• Use vibium map --selector to reduce noise on large pages
• Use vibium fill to replace a field's value, vibium type to append to it
• Use vibium find --text / --label / --testid for semantic element lookup (more reliable than CSS selectors)
• Use vibium find --role for ARIA-role-based lookup
• Use vibium a11y-tree to understand page structure without visual rendering
• Use vibium text "<selector>" to read specific sections
• Use vibium diff map after interactions to see what changed
• vibium eval is the escape hatch for complex DOM queries
• vibium check/vibium uncheck are idempotent — safe to call without checking state first
• Screenshots save to the current directory by default (-o to change)
• Use vibium storage-state / vibium restore-storage to persist auth across sessions
