# 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:

```sh
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.

## Commands

## Common Patterns

### Ref-based workflow (recommended for AI)
```sh
vibium go https://example.com
vibium map
vibium click @e1
vibium map  # re-map after interaction
```

### Verify action worked
```sh
vibium map
vibium click @e3
vibium diff map  # see what changed
```

### Read a page
```sh
vibium go https://example.com && vibium text
```

### Fill a form (end-to-end)
```sh
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)
```sh
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)
```sh
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
```sh
# 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
```sh
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
```sh
vibium go https://example.com && vibium a11y-tree
```

### Multi-tab workflow
```sh
vibium tab-new https://docs.example.com
vibium text "h1"
vibium tab-switch 0
```

### Annotated screenshot
```sh
vibium screenshot -o annotated.png --annotate
```

### Inspect an element
```sh
vibium attr "a" "href"
vibium value "input[name=email]"
vibium is-visible ".modal"
```

### Save as PDF
```sh
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:
```sh
vibium eval 'document.title'
vibium eval 'document.querySelectorAll("li").length'
```

**Complex scripts** — use `--stdin` with a heredoc:
```sh
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:
```sh
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

| Flag | Description |
|------|-------------|
| `--headless` | Hide browser window |
| `--json` | Output as JSON |
| `-v, --verbose` | Debug logging |

## 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
