# Browser Automation with agent-browser
|
|
|
|
> **⚠️ Prerequisite**: This module requires the `agent-browser` CLI tool.
|
|
> Ensure it is installed in your environment before using:
|
|
> `npm install -g @vercel/agent-browser` (or equivalent)
|
|
|
|
## 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
|
|
```
|
|
|
|
### 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
|
|
```
|
|
|
|
## Example: Authentication with saved state
|
|
|
|
```bash
|
|
# Login once
|
|
agent-browser open https://app.example.com/login
|
|
agent-browser snapshot -i
|
|
agent-browser fill @e1 "username"
|
|
agent-browser fill @e2 "password"
|
|
agent-browser click @e3
|
|
agent-browser wait --url "**/dashboard"
|
|
agent-browser state save auth.json
|
|
|
|
# Later sessions: load saved state
|
|
agent-browser state load auth.json
|
|
agent-browser open https://app.example.com/dashboard
|
|
```
|
|
|
|
## 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
|
|
```
