Risky Biz Podcast: Making Reachability Analysis Work in Real-World Codebases
This episode explores the hard problem of reachability analysis, from static analysis limits to handling dynamic languages and massive dependency trees.
@risingstack/gc-stats
Advanced tools
Exposes stats about V8 GC after it has been executed.
Create a new instance of the module and subscribe to stats
-events from that:
var gc = (require('gc-stats'))();
gc.on('stats', function (stats) {
console.log('GC happened', stats);
});
This will print blobs like this whenever a GC happened:
GC happened {
pause: 433034,
pauseMS: 0,
gctype: 1,
before: {
totalHeapSize: 18635008,
totalHeapExecutableSize: 4194304,
usedHeapSize: 12222496,
heapSizeLimit: 1535115264
}, after: {
totalHeapSize: 18635008,
totalHeapExecutableSize: 4194304,
usedHeapSize: 8116600,
heapSizeLimit: 1535115264
}, diff: {
totalHeapSize: 0,
totalHeapExecutableSize: 0,
usedHeapSize: -4105896,
heapSizeLimit: 0
}
}
npm install gc-stats
