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 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.

Use the StackBlitz SDK to seamlessly embed live, interactive code playgrounds (WebContainers) directly into documentation, blog posts, or tutorials. This method allows users to view and experiment with code examples (e.g., React, TypeScript) without leaving the current page, making tutorials and documentation highly engaging and functional. Supports embedding from GitHub repositories or creating inline projects.

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 bundle collects comprehensive diagnostic information about the WebContainer environment. It checks the boot state, file system integrity, running process list, and modern browser support (e.g., SharedArrayBuffer, cross-origin isolation). Essential for developers integrating with StackBlitz SDK or WebContainers to troubleshoot complex development issues.

This skill facilitates the deployment of WebContainer applications to popular hosting platforms like Vercel and Netlify. It handles complex configuration, including setting necessary COOP/COEP security headers. It is essential when developing modern web projects using WebContainers or the StackBlitz SDK, ensuring proper and secure deployment.

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.

This skill focuses on optimizing the performance of WebContainers, specifically targeting improvements in boot time, file system mounting efficiency, and process spawning. It is essential for developers utilizing the WebContainer API or the StackBlitz SDK to ensure a stable and efficient development environment, especially in complex web applications.

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 skill provides the production-grade architectural blueprint for developing browser-based Integrated Development Environments (IDEs) and interactive playgrounds powered by WebContainers. It is essential for developers who are integrating the WebContainers API or utilizing the StackBlitz SDK to create robust, cloud-based development experiences.

This comprehensive guide details essential security practices for deploying WebContainers. It covers implementing Content Security Policy (CSP) headers, ensuring robust sandbox isolation, and performing rigorous input validation to mitigate common web vulnerabilities. Use this when developing applications with WebContainers or the StackBlitz SDK.
