Execute RxJS code in an isolated environment and capture the stream emissions, timeline, and performance metrics. Code runs in a separate worker thread for security.

Generate ASCII marble diagrams to visualize RxJS stream emissions over time

Analyze RxJS code for creation functions, operators, performance patterns, and best practices

Analyze RxJS code for potential memory leaks and subscription management issues. Recognizes modern auto-cleanup patterns (takeUntilDestroyed, async pipe, useEffect cleanup, onUnmounted) to avoid false positives.

Suggest RxJS patterns and best practices for common use cases

Lint RxJS code snippets for common issues and best practices (regex-based best-effort analysis, no ESLint runtime required). Based on eslint-plugin-rxjs-x rules. Checks for nested subscribes, memory leaks, deprecated patterns, and more. Rules marked as type-info-required use heuristics and may have false positives/negatives. Supports framework-specific rules for Angular, React, and Vue.
