Node.js SDK

Lexmount Node.js SDK is the typed JavaScript and TypeScript client for browser sessions, persistent contexts, extensions, stored downloads, regions, and CDP connections.

Install

npm install lexmount

Node.js 18 or later is required. Install playwright separately when your application connects to a browser.

Current browser names

Keep normal and light in code. The product UI displays them as Chromium and Moli.

What the SDK covers

• Async session creation, status polling, list/get/close, targets, and stored downloads
• Region catalog discovery and explicit region selection
• Persistent context create/list/get/fork/delete and emergency force-release
• Extension upload/list/get/delete and session mounting
• Custom images, window size, custom or official proxy, and LightMount options
• Structured errors, logging, CDP helpers, and integrated-auth callbacks

Configuration

export LEXMOUNT_PROJECT_ID=<your-project-id>
