Dependency State Recovery Stackblitz manages project environments by automatically installing dependencies defined in the package.json file upon project load. This ensures that the WebContainer environment matches the declared versioning. A challenge arises when a dependency upgrade is performed that introduces breaking changes or installation failures, caus
When utilizing the StackBlitz deployment workflow for Vite-based projects, the build process relies on specific environment variable configurations to successfully bundle the application. If a referenced variable is missing or improperly prefixed, the deployment may fail during the build phase. The current behavior involves streaming build logs to the Deploy
Header Configuration for Self-Hosted WebContainer Environments StackBlitz WebContainers enable client-side Node.js execution through WebAssembly, shifting compute costs to the browser. For low-traffic workloads, hosting static project files on a CDN eliminates persistent server infrastructure. However, the WebContainer runtime requires Cross-Origin-Embedder-
StackBlitz surfaces TypeScript errors, build failures, and WebContainer process crashes through a bell icon in the activity bar. The notification system currently offers only a global enable/disable toggle without per-category severity filtering. A specific unresolved behavior is whether dismissed notifications retain their state across browser sessions or a
Background StackBlitz’s GitHub integration pushes local edits to the GitHub API and pulls remote commits. When the API returns a 429 response, the sync service must decide how to retry. The current implementation has not yet chosen between an exponential backoff with jitter or a fixed retry interval, leaving the retry policy unresolved. Constraints Free‑tier
Goal: Enable a repeatable StackBlitz development environment where long‑running processes such as a local database or WebSocket server continue to operate after the browser tab is backgrounded or closed, preserving state across sessions. Constraint: WebContainers currently bind all Node.js processes to the active tab’s lifecycle; there is no documented API o
StackBlitz WebContainers shift the Node.js runtime from a remote server to the user's browser via WebAssembly. This architecture is designed to reduce backend infrastructure costs for low-traffic workloads by leveraging client-side compute. While this removes the need for persistent virtual machine provisioning, the runtime's performance depends on the host'
Goal: Determine whether Stackblitz imposes a limit on the number of simultaneous Live Preview WebSocket connections that can be opened for a single project, and whether this limit can be adjusted. Constraints: The Live Preview documentation states that a session is created per browser tab but does not specify a hard maximum or provide a user‑configurable set
