Is it possible to temporarily disable GC in node.js when executing a certain piece of code?

Question

JavaScript

When executing latency-sensitive code, you want to temporarily disable the GC and enable it back, something like this:

disableGc();
runCodeWithoutDelays();
enableGc();

Is it possible to do this with some node.js flags, native modules? Or can I write my own module for this, is there the necessary API in V8?

Answer 1

No, but you can turn off the automatic garbage collector with command line switches and call it yourself, as needed:
node --nouse-idle-notification --expose-gc program.js
Now the gc() function will appear in the global, which you need to call.
