# Browser Automation with agent-browser

IMPORTANT: Before navigating to `localhost:3000`, you MUST load the auth cookies found in apps/viewer/src/test/.auth/user.json

```bash
agent-browser cookies set "authjs.session-token" "<value-from-user.json>"
agent-browser cookies set "authjs.csrf-token" "<value-from-user.json>"
agent-browser open http://localhost:3000/typebots
```

## Quick start

```bash
agent-browser open <url>        # Navigate to page
agent-browser snapshot -i       # Get interactive elements with refs
agent-browser click @e1         # Click element by ref
agent-browser fill @e2 "text"   # Fill input by ref
agent-browser close             # Close browser
```

## Core workflow

1. Navigate: `agent-browser open <url>`
2. Snapshot: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`)
3. Interact using refs from the snapshot
4. Re-snapshot after navigation or significant DOM changes

## Commands

### Navigation

```bash
agent-browser open <url>      # Navigate to URL
agent-browser back            # Go back
agent-browser forward         # Go forward
agent-browser reload          # Reload page
agent-browser close           # Close browser
```

### Snapshot (page analysis)

```bash
agent-browser snapshot        # Full accessibility tree
agent-browser snapshot -i     # Interactive elements only (recommended)
agent-browser snapshot -c     # Compact output
agent-browser snapshot -d 3   # Limit depth to 3
```

### Interactions (use @refs from snapshot)

```bash
agent-browser click @e1           # Click
agent-browser dblclick @e1        # Double-click
agent-browser fill @e2 "text"     # Clear and type
agent-browser type @e2 "text"     # Type without clearing
agent-browser press Enter         # Press key
agent-browser press Control+a     # Key combination
agent-browser hover @e1           # Hover
agent-browser check @e1           # Check checkbox
agent-browser uncheck @e1         # Uncheck checkbox
agent-browser select @e1 "value"  # Select dropdown
agent-browser scroll down 500     # Scroll page
agent-browser scrollintoview @e1  # Scroll element into view
```

### Get information

```bash
agent-browser get text @e1        # Get element text
agent-browser get value @e1       # Get input value
agent-browser get title           # Get page title
agent-browser get url             # Get current URL
```

### Screenshots

```bash
agent-browser screenshot          # Screenshot to stdout
agent-browser screenshot path.png # Save to file
agent-browser screenshot --full   # Full page
```

Prefer full page screenshot to get as much information as possible.

### Wait

```bash
agent-browser wait @e1                     # Wait for element
agent-browser wait 2000                    # Wait milliseconds
agent-browser wait --text "Success"        # Wait for text
agent-browser wait --load networkidle      # Wait for network idle
```

### Semantic locators (alternative to refs)

```bash
agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "user@test.com"
```

## Example: Form submission

```bash
agent-browser open https://example.com/form
agent-browser snapshot -i
# Output shows: textbox "Email" [ref=e1], textbox "Password" [ref=e2], button "Submit" [ref=e3]

agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "password123"
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser snapshot -i  # Check result
```

## Cookies management

```bash
agent-browser cookies get              # Get all cookies
agent-browser cookies get --json       # Get as JSON
agent-browser cookies set <name> <val> # Set a cookie
agent-browser cookies clear            # Clear all cookies
```

## Sessions (parallel browsers)

```bash
agent-browser --session test1 open site-a.com
agent-browser --session test2 open site-b.com
agent-browser session list
```

## JSON output (for parsing)

Add `--json` for machine-readable output:

```bash
agent-browser snapshot -i --json
agent-browser get text @e1 --json
```

## Debugging

```bash
agent-browser open example.com --headed  # Show browser window
agent-browser console                    # View console messages
agent-browser errors                     # View page errors
```
