Notable Changes

Extended support for AbortSignal in child_process and stream

The following APIs now support an AbortSignal in their options object:

  • child_process.spawn()

Calling .abort() on the corresponding AbortController is similar to calling .kill() on the child process except the error passed to the callback will be an AbortError: 

const controller = new AbortController();
const { signal } = controller;
const grep = spawn('grep', ['ssh'], { signal });
grep.on('error', (err) => {
  // This will be called with err being an AbortError if the controller aborts
});
controller.abort(); // stops the process
  • new stream.Writable() and new stream.Readable()

Calling .abort() on the corresponding AbortController will behave the same way as calling .destroy(new AbortError()) on the stream: 

const { Readable } = require('stream');
const controller = new AbortController();
const read = new Readable({
  read(size) {
    // ...
  },
  signal: controller.signal
});
// Later, abort the operation closing the stream
controller.abort();

Contributed by Benjamin Gruenbaum #36431, #36432.

BigInt support in querystring.stringify()

If querystring.stringify() is called with an object that contains BigInt values, they will now be serialized to their decimal representation instead of the empty string: 

const querystring = require('querystring');
console.log(querystring.stringify({ bigint: 2n ** 64n }));
// Prints: bigint=18446744073709551616

Contributed by Darshan Sen #36499.

Additions to the C++ embedder APIs

A new IsolateSettingsFlag is available for those calling SetIsolateUpForNode(): SHOULD_NOT_SET_PREPARE_STACK_TRACE_CALLBACK can be used to prevent Node.js from setting a custom callback to prepare stack traces.

Contributed by Shelley Vohr #36447.

Added node::GetEnvironmentIsolateData() and node::GetArrayBufferAllocator() to respectively get the current IsolateData* and, from it, the current Node.js ArrayBufferAllocator if there is one.

Contributed by Anna Henningsen #36441.
