Frontend Memory Leaks: A 500-Repository Static Analysis and Five-Scenario Benchmark Study
We scanned 500 public React, Vue, and Angular repositories with AST-based static analysis and found 55,864 missing-cleanup patterns — 86% of repos had at least one. Then we benchmarked five common leak scenarios (useEffect listeners, onMounted timers, RxJS subscriptions, Vue watchers, RAF) across 100 mount/unmount cycles with 50 repeats. Every pattern leaked ~8 KB per cycle. This article presents the full data, statistical validation, framework comparison, and one-line fixes.
