Most Unix syscalls have Windows equivalents, but behavior may differ on Windows

relative to Linux and macOS. For an example of the subtle ways in which it's

sometimes impossible to replace Unix syscall semantics on Windows, see [Node.js

issue 4760](https://github.com/nodejs/node/issues/4760).

The latest version of the V8 inspector protocol is published on the

[Chrome DevTools Protocol Viewer][].

Node.js inspector supports all the Chrome DevTools Protocol domains declared

by V8. Chrome DevTools Protocol domain provides an interface for interacting

with one of the runtime agents used to inspect the application state and listen

to the run-time events.

If the module identifier passed to `require()` is not a

[core](#modules_core_modules) module, and does not begin with `'/'`, `'../'`, or

`'./'`, then Node.js starts at the parent directory of the current module, and

adds `/node_modules`, and attempts to load the module from that location.

Node.js will not append `node_modules` to a path already ending in

`node_modules`.

If it is not found there, then it moves to the parent directory, and so

on, until the root of the file system is reached.

Node.js prefixes all postmortem constants with `nodedbg_`, and they complement

V8 constants by providing ways to inspect Node.js-specific structures, like

`node::Environment`, `node::BaseObject` and its descendants, classes from

`src/utils.h` and others. Those constants are declared in

`src/node_postmortem_metadata.cc`, and most of them are calculated at compile

There are also tests on `test/cctest/test_node_postmortem_metadata.cc` to make

sure all Node.js postmortem metadata are calculated correctly.

as JavaScript.

.It Fl h , Fl -help

Print Node.js command line options.

The output of this option is less detailed than this document.

.It Fl i , Fl -interactive

at startup.

Follows `require()`'s module resolution rules.

.Ar module

may be either a path to a file, or a Node.js module name.

.It Fl v , Fl -version

Print node's version.

A space-separated list of command-line

.Ar options ,

which are interpreted as if they had been specified on the command-line before the actual command (so they can be overridden).

Node.js will exit with an error if an option that is not allowed in the environment is used, such as

.Fl -print

or a script file.
