punycode.toUnicode()

punycode.toUnicode(domain) Converts a Punycode string representing a domain name to Unicode. Only the Punycoded parts of the domain name will be converted, i.e. it doesn't matter if you call it on a string that has already been converted to Unicode. // decode domain names punycode.toUnicode('xn--maana-pta.com'); // 'mañana.com' punycode.toUnicode('xn----dqo34k.com'); // '☃-⌘.com'

punycode.toASCII()

punycode.toASCII(domain) Converts a Unicode string representing a domain name to Punycode. Only the non-ASCII parts of the domain name will be converted, i.e. it doesn't matter if you call it with a domain that's already in ASCII. // encode domain names punycode.toASCII('mañana.com'); // 'xn--maana-pta.com' punycode.toASCII('☃-⌘.com'); // 'xn----dqo34k.com'

punycode.encode()

punycode.encode(string) Converts a string of Unicode symbols to a Punycode string of ASCII-only symbols. // encode domain name parts punycode.encode('mañana'); // 'maana-pta' punycode.encode('☃-⌘'); // '--dqo34k'

punycode.decode()

punycode.decode(string) Converts a Punycode string of ASCII-only symbols to a string of Unicode symbols. // decode domain name parts punycode.decode('maana-pta'); // 'mañana' punycode.decode('--dqo34k'); // '☃-⌘'

process.versions

process.versions A property exposing version strings of Node.js and its dependencies. console.log(process.versions); Will print something like: { http_parser: '2.3.0', node: '1.1.1', v8: '4.1.0.14', uv: '1.3.0', zlib: '1.2.8', ares: '1.10.0-DEV', modules: '43', icu: '55.1', openssl: '1.0.1k' }

process.version

process.version A compiled-in property that exposes NODE_VERSION. console.log(`Version: ${process.version}`);

process.uptime()

process.uptime() Number of seconds Node.js has been running.

process.umask()

process.umask([mask]) Sets or reads the process's file mode creation mask. Child processes inherit the mask from the parent process. Returns the old mask if mask argument is given, otherwise returns the current mask. const newmask = 0o022; const oldmask = process.umask(newmask); console.log( `Changed umask from ${oldmask.toString(8)} to ${newmask.toString(8)}` );

process.title

process.title Getter/setter to set what is displayed in ps. When used as a setter, the maximum length is platform-specific and probably short. On Linux and OS X, it's limited to the size of the binary name plus the length of the command line arguments because it overwrites the argv memory. v0.8 allowed for longer process title strings by also overwriting the environ memory but that was potentially insecure/confusing in some (rather obscure) cases.

process.stdout

process.stdout A Writable Stream to stdout (on fd 1). For example, a console.log equivalent could look like this: console.log = (msg) => { process.stdout.write(`${msg}\n`); }; process.stderr and process.stdout are unlike other streams in Node.js in that they cannot be closed (end() will throw), they never emit the 'finish' event and that writes can block when output is redirected to a file (although disks are fast and operating systems normally employ write-back caching so it should be a
