Other libraries are located in the deps/ directory in the Node.js source Node.js includes other statically linked libraries including OpenSSL. Use, the most important of which is the node::ObjectWrap class. Node.js itself exports C++ APIs that addons can Offloading work via libuv to non-blocking system operations, worker threads, Addon authors shouldĪvoid blocking the event loop with I/O or other time-intensive tasks by More sophisticated asynchronous addons that need to move beyond the libuvĪlso provides a threading abstraction similar to POSIX threads for Serves as a cross-platform abstraction library, giving easy, POSIX-likeĪccess across all major operating systems to many common system tasks, suchĪs interacting with the file system, sockets, timers, and system events. Threads and all of the asynchronous behaviors of the platform. Libuv: The C library that implements the Node.js event loop, its worker V8.h header file ( deps/v8/include/v8.h in the Node.js source V8 provides the mechanisms for creating objects,Ĭalling functions, etc. V8: the C++ library Node.js uses to provide the Involving knowledge of several components and APIs: When not using Node-API, implementing addons is complicated, Refer to C/C++ addons with Node-API for more information on Unless there is a need forĭirect access to functionality which is not exposed by Node-API, use Node-API. Use of internal V8, libuv, and Node.js libraries. There are three options for implementing addons: Node-API, nan, or direct Require() function can load addons as ordinary Node.js modules.Īddons provide an interface between JavaScript and C/C++ libraries. resolve( '// If the current working directory is /home/myself/node, // this returns '/home/myself/node/path.Addons are dynamically-linked shared objects written in C++. If no path segments are passed, path.resolve() will return the absolute path The resulting path is normalized and trailing slashes are removed unless the If, after processing all given path segments, an absolute path has not yetīeen generated, the current working directory is used. Subsequent path prepended until an absolute path is constructed.įor instance, given the sequence of path segments: /foo, /bar, baz,Ĭalling path.resolve('/foo', '/bar', 'baz') would return /bar/bazīecause 'baz' is not an absolute path but '/bar' + '/' + 'baz' is. The given sequence of paths is processed from right to left, with each The path.resolve() method resolves a sequence of paths or path segments into paths A sequence of paths or path segments They are purely for formatting.) copyĪ TypeError is thrown if path is not a string. (All spaces in the "" line should be ignored. pathObject.ext and pathObject.name are ignored if pathObject.base existsįor example, on POSIX: // If `dir`, `root` and `base` are provided, // `$ copy ┌─────────────────────┬────────────┐.pathObject.root is ignored if pathObject.dir is provided. When providing properties to the pathObject remember that there areĬombinations where one property has priority over another: The path.format() method returns a path string from an object.
