Deoptigate is a CLI tool that investigates V8/Node.js function deoptimizations by processing v8 logs and presenting them in a visual viewer. It helps developers track down and fix performance bottlenecks caused by deoptimized functions.
Use cases
- investigate why my node.js function got deoptimized
- analyze v8 log for deoptimizations
- find performance bottlenecks in node app
- visualize v8 optimization and deoptimization events
- debug slow javascript functions in node
When to choose
- you're profiling node.js apps and need to see deoptimizations inline with source code
- you have existing *-v8.log files you want to analyze visually
When to avoid
- you need general CPU profiling rather than deoptimization analysis
- you're targeting browsers or non-V8 runtimes
