Notable Changes
ECMAScript Modules - --experimental-modules flag removal

As of Node.js 12.17.0, the --experimental-modules flag is no longer necessary
to use ECMAScript modules (ESM). However, the ESM implementation in Node.js
remains experimental. As per our stability index: “The feature is not subject
to Semantic Versioning rules. Non-backward compatible changes or removal may
occur in any future release.” Users should be cautious when using the feature
in production environments.

Unlike Node.js 14, using ESM will still emit a runtime experimental warning,
either when a module is used a the application's entrypoint or the first time
dynamic import() is called.

Please keep in mind that the implementation of ESM in Node.js differs from the
developer experience you might be familiar with. Most transpilation workflows
support features such as named exports from CommonJS module imports, optional
file extensions or JSON modules that the Node.js ESM implementation does not
support. It is highly likely that modules from transpiled environments will
require a certain degree of refactoring to work in Node.js. It is worth
mentioning that many of our design decisions were made with two primary goals.
Spec compliance and Web Compatibility. It is our belief that the current
implementation offers a future proof model to authoring ESM modules that paves
the path to Universal JavaScript. Please read more in our documentation.

The ESM implementation in Node.js is still experimental but we do believe that
we are getting very close to being able to call ESM in Node.js “stable”.
Removing the flag is a huge step in that direction.

We expect to remove the warning Node.js 12 later this year, possibly in late
October, when Node.js 14 will become LTS.

AsyncLocalStorage API (experimental)

The AsyncLocalStorage class has been introduced in the Async Hooks module.

This API allows keeping a context across asynchronous operations. For instance,
if a sequence id is stored within an instance of AsyncLocalStorage for each
HTTP request entering in a server, it will be possible to retrieve this id
without having access the current HTTP request:

const http = require('http');
const { AsyncLocalStorage } = require('async_hooks');

const asyncLocalStorage = new AsyncLocalStorage();

function logWithId(msg) {
  const id = asyncLocalStorage.getStore();
  console.log(`${id !== undefined ? id : '-'}: `, msg);
}

let idSeq = 0;
http.createServer((req, res) => {
  asyncLocalStorage.run(idSeq++, () => {
    logWithId('start');
    // Imagine any chain of async operations here.
    setImmediate(() => {
      logWithId('finish');
      res.end();
    });
  });
}).listen(8080);

In this example, the logWithId function will always know what the current
request id is, even when there are multiple requests in parallel.

What can this API be used for

Use cases of this API include:

  • Logging
  • User identification
  • Performance tracking
  • Error tracking and handling
  • Much more!

Note: This API is still experimental and some methods might change in future releases of Node.js

REPL previews

If further input is predicable, a suggestion is inserted as preview.

The REPL now supports previews similar to the Chrome DevTools console. An input
suggestion is inserted as preview in case further input is predicable. The
suggestion may be accepted by either pressing <TAB> or <RIGHT> at the end of
the input.
On top of that, output is previewed when entering variable names or function
calls that have no side effect.

Check the preview in action
and try it out on your own. Just access the REPL on your terminal by starting
the Node.js executable without any further command.

REPL reverse-i-search

The REPL supports bi-directional reverse-i-search similar to
ZSH. It is triggered with <ctrl> + R
to search backwards and <ctrl> + S to search forwards.

Entries are accepted as soon as any button is pressed that doesn't correspond
with the reverse search. Cancelling is possible by pressing escape or
<ctrl> + C.

Changing the direction immediately searches for the next entry in the expected
direction from the current position on.

REPL substring-based search

It is now possible to access former history entries very fast by writing the
first characters of the formerly entered code you are looking for. Then push
<UP> or <DOWN> to go through the history entries that start with those
characters.

It works similar to the Fish Shell substring-based
history search.

Contributed by Ruben Bridgewater - #​31112.

Error monitoring
Monitoring error events

It is now possible to monitor 'error' events on an EventEmitter without
consuming the emitted error by installing a listener using the symbol
EventEmitter.errorMonitor:

const myEmitter = new MyEmitter();

myEmitter.on(EventEmitter.errorMonitor, (err) => {
  MyMonitoringTool.log(err);
});

myEmitter.emit('error', new Error('whoops!'));
// Still throws and crashes Node.js

Contributed by Gerhard Stoebich - #​30932.

Monitoring uncaught exceptions

It is now possible to monitor 'uncaughtException' events without overriding
the default behavior that exits the process by installing an
'uncaughtExceptionMonitor' listener:

process.on('uncaughtExceptionMonitor', (err, origin) => {
  MyMonitoringTool.logSync(err, origin);
});

// Intentionally cause an exception, but do not catch it.
nonexistentFunc();
// Still crashes Node.js

Contributed by Gerhard Stoebich - #​31257.

File system APIs
New function: fs.readv

This new function (along with its sync and promisified versions) takes an array
of ArrayBufferView elements and will write the data it reads sequentially to
the buffers.

Contributed by Sk Sajidul Kadir - #​32356.

Optional parameters in fs.read

A new overload is available for fs.read (along with its sync and promisified
versions), which allows to optionally pass any of the offset, length and
position parameters.

Contributed by Lucas Holmquist - #​31402.

Console groupIndentation option

The Console constructor (require('console').Console) now supports different group indentations.

This is useful in case you want different grouping width than 2 spaces.

const { Console } = require('console');
const customConsole = new Console({
  stdout: process.stdout,
  stderr: process.stderr,
  groupIndentation: 10
});

customConsole.log('foo');
// 'foo'
customConsole.group();
customConsole.log('foo');
//           'foo'

Contributed by rickyes - #​32964.

maxStringLength option for util.inspect()

It is now possible to limit the length of strings while inspecting objects.
This is possible by passing through the maxStringLength option similar to:

const { inspect } = require('util');

const string = inspect(['a'.repeat(1e8)], { maxStringLength: 10 });

console.log(string);
// "[ 'aaaaaaaaaa'... 99999990 more characters ]"

Contributed by rosaxny - #​32392.

Stable N-API release 6

The following N-API features are now stable as part of the N-API 6 release:

Stable diagnostic reports

The Diagnostic Report
feature is now stable and supports a new --report-compact flag to write the
reports in a compact, single-line JSON format, more easily consumable by log
processing systems than the default multi-line format designed for human
consumption.

Increase of the default server headers timeout

The default value of server.headersTimeout for http and https servers was
increased from 40000 to 60000 (60 seconds). This to accomodate for systems
like AWS ELB that have a timeout of 60 seconds.
