npm 7 - #35631

Node.js 15 comes with a new major release of npm, npm 7. npm 7 comes with many new features - including npm workspaces and a new package-lock.json format. npm 7 also includes yarn.lock file support. One of the big changes in npm 7 is that peer dependencies are now installed by default.

Throw On Unhandled Rejections - #33021

As of Node.js 15, the default mode for unhandledRejection is changed to throw (from warn). In throw mode, if an unhandledRejection hook is not set, the unhandledRejection is raised as an uncaught exception. Users that have an unhandledRejection hook should see no change in behavior, and it’s still possible to switch modes using the --unhandled-rejections=mode process flag.

QUIC - #32379

Node.js 15 comes with experimental support QUIC, which can be enabled by compiling Node.js with the --experimental-quic configuration flag. The Node.js QUIC implementation is exposed by the core net module.

V8 8.6 - #35415

The V8 JavaScript engine has been updated to V8 8.6 (V8 8.4 is the latest available in Node.js 14). Along with performance tweaks and improvements the V8 update also brings the following language features:

Promise.any() (from V8 8.5)

AggregateError (from V8 8.5)

String.prototype.replaceAll() (from V8 8.5)

Logical assignment operators &&=, ||=, and ??= (from V8 8.5)
