Node.js 17.0.0 ソフトウェア情報交換

What's new in this version:

Notable Changes:
Deprecations and Removals:
- (SEMVER-MAJOR) dns: runtime deprecate type coercion of dns.lookup options
- doc: deprecate (doc-only) http abort related
- (SEMVER-MAJOR) module: subpath folder mappings EOL
- (SEMVER-MAJOR) module: runtime deprecate trailing slash patterns

OpenSSL 3.0:
- Node.js now includes OpenSSL 3.0, specifically quictls/openssl which provides QUIC support. With OpenSSL 3.0 FIPS support is again available using the new FIPS module. For details about how to build Node.js with FIPS support please see BUILDING.md.
- While OpenSSL 3.0 APIs should be mostly compatible with those provided by OpenSSL 1.1.1, we do anticipate some ecosystem impact due to tightened restrictions on the allowed algorithms and key sizes
- If you hit an ERR_OSSL_EVP_UNSUPPORTED error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A command-line option, --openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions
- For details about all the features in OpenSSL 3.0 please see the OpenSSL 3.0 release blog

V8 9.5:
- The V8 JavaScript engine is updated to V8 9.5. This release comes with additional supported types for the Intl.DisplayNames API and Extended timeZoneName options in the Intl.DateTimeFormat API.

Readline Promise API:
- The readline module provides an interface for reading data from a Readable
stream (such as process.stdin) one line at a time

The following simple example illustrates the basic use of the readline module:
- import * as readline from 'node:readline/promises'
- import { stdin as input, stdout as output } from 'process'
- const rl = readline.createInterface({ input, output })
- const answer = await rl.question('What do you think of Node.js? ')
- console.log(`Thank you for your valuable feedback: ${answer}`)
- rl.close()

Other Notable Changes:
- (SEMVER-MAJOR) dns: default to verbatim=true in dns.lookup()
- (SEMVER-MAJOR) errors: print Node.js version on fatal exceptions that cause exit
- deps: upgrade npm to 8.1.0
- (SEMVER-MINOR) fs: add FileHandle.prototype.readableWebStream()
- (SEMVER-MAJOR) lib: add structuredClone() global
- (SEMVER-MAJOR) lib: expose DOMException as global
- (SEMVER-MAJOR) stream: finished should error on errored stream
