This guide details how to use Skyvern's AI-powered Command Line Interface (CLI) for advanced browser automation. Users can perform tasks such as quick data validation, structured data extraction, form filling, secure login, and building complex, multi-step, reusable workflows across various websites. It offers solutions for scenarios where deterministic selectors fail.

Master event-driven patterns within Snowflake using native alerts, email integrations, external functions, and cloud notification services (S3/GCS). This skill is essential for building robust, reactive pipelines that trigger actions (like sending alerts, calling external APIs, or ingesting data) in response to data changes or specific system events. Use cases include data quality checks, real-time monitoring, and automated notifications.

This skill provides Continuous Integration (CI) testing for applications built with WebContainer and StackBlitz SDK. It utilizes Playwright browser tests to ensure code reliability and functional correctness across various environments. Ideal for developers integrating WebContainers into CI pipelines or working within the StackBlitz development ecosystem.

This comprehensive guide provides solutions for common and complex errors encountered when using WebContainer and StackBlitz environments. It covers essential fixes for cross-origin isolation headers (COOP/COEP), managing WebContainer boot failures using singleton patterns, resolving npm installation hangs, and handling file system errors (ENOENT). Use this skill to stabilize and debug complex web development sandboxes.

This workflow details how to build a complete, browser-based Integrated Development Environment (IDE). Using WebContainers, it integrates key components like a file explorer, Monaco editor, integrated terminal, and live preview. This architecture is crucial for developing interactive coding playgrounds, educational web tools, or embedding robust development sandboxes into existing web applications.

Guides developers through the pricing tiers of StackBlitz, covering free embedding options and commercial licensing for the WebContainer API. This skill is essential when integrating WebContainers or utilizing the StackBlitz SDK, ensuring correct setup, cost management, and adherence to official usage guidelines.

This guide demonstrates how to set up a complete development environment entirely within a web browser using the WebContainer API. It covers mounting a virtual file system, installing Node.js dependencies via npm, and starting a local dev server (like Express) without needing a dedicated backend server. It is ideal for learning WebContainers, building browser-based IDEs, or prototyping Node.js applications client-side.

This guide details how to install and configure the WebContainer API, enabling client-side Node.js execution directly in the browser. It also provides instructions for integrating the StackBlitz SDK, which is used for embedding highly interactive code editors into web applications. The guide covers necessary dependency installations, code examples, and crucial HTTP header configuration (COOP/COEP) required for cross-origin isolation and secure operation.

A comprehensive guide to setting up a local development loop for WebContainer applications. This setup utilizes Vite for a modern development environment, providing hot module replacement (HMR) and cross-origin policy configuration. It includes detailed steps for running Vitest tests, ensuring file system operations and browser-based IDE features function correctly in a simulated local environment.

Provides a comprehensive production checklist specifically for WebContainer applications built using the StackBlitz SDK. This guide helps developers ensure that their web applications are robust and ready for deployment by checking essential aspects like security headers, cross-browser compatibility, and necessary fallback mechanisms.

This guide provides essential knowledge on resource limitations within WebContainer environments (such as memory, CPU, file system size, and process count). It is crucial for developers utilizing the WebContainers API or StackBlitz SDK to understand these constraints. Learn best practices for monitoring memory usage, optimizing mounted file systems by excluding unnecessary assets (like test or documentation folders), and managing dependencies to prevent common issues like Out-Of-Memory (OOM) crashes and slow build times.

This comprehensive guide provides production-ready patterns for the WebContainer API, essential for building sophisticated online IDEs and code playgrounds. It covers key functionalities such as singleton WebContainer management, robust file system CRUD operations, process lifecycle management, jsh terminal emulation, and embedding projects using the StackBlitz SDK. Ideal for developers creating collaborative development environments.
