module: resolve and instantiate loader pipeline hooks by guybedford · Pull Request #15445 · nodejs/node

This enables a --loader flag for Node, which can provide custom
"resolve" and "dynamicInstantiate" methods for custom ES module
loading.

In the process, module providers have been converted from classes
into functions and the module APIs have been made to pass URL strings
over objects.

Add `"dynamic"` to the list of supported `format`s returned by a
custom resolve hook.

Add a table describing the meaning of each `format`.

Refs: nodejs#15445

Notable Changes:

* crypto:
  - expose ECDH class
    #8188
* http2:
  - http2 is now exposed by defualt without the need for a flag
    #15685
  - a new environment varible NODE\_NO\_HTTP2 has been added to allow
    userland http2 to be required
    #15685
  - support has been added for generic `Duplex` streams
    #16269
* module:
  - resolve and instantiate loader pipeline hooks have been added to
    the ESM lifecycle
    #15445
* zlib:
  - CVE-2017-14919 - In zlib v1.2.9, a change was made that causes an
    error to be raised when a raw deflate stream is initialized with
    windowBits set to 8. On some versions this crashes Node and you
    cannot recover from it, while on some versions it throws an
    exception. Node.js will now gracefully set windowBits to 9
    replicating the legacy behavior to avoid a DOS vector.
