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.

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.

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.

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.

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.
