Node.js is an, for executing JavaScript code. Historically, JavaScript was used primarily for, in which scripts written in JavaScript are embedded in a webpage's HTML, to be run client-side by a JavaScript engine in the user's web browser. Node.js enables JavaScript to be used for, and runs scripts server-side to produce content before the page is sent to the user's web browser. Consequently, Node.js has become one of the foundational elements of the 'JavaScript everywhere' paradigm, allowing development to unify around a single programming language, rather than rely on a different language for writing server side scripts. Though.js is the conventional for JavaScript code, the name 'Node.js' does not refer to a particular file in this context and is merely the name of the product. Node.js has an capable of.

These design choices aim to optimize and in with many input/output operations, as well as for applications (e.g., programs and ). The Node.js project, governed by the Node.js Foundation, is facilitated by the 's Collaborative Projects program. Corporate users of Node.js software include,,,,,,,,,,,,, and.

Ryan Dahl, creator of Node.js, in 2010 Node.js was originally written by Ryan Dahl in 2009, about thirteen years after the introduction of the first server-side JavaScript environment, Netscape's LiveWire Pro Web. The initial release supported only Linux and Mac OS X. Its development and maintenance was led by Dahl and later sponsored. Dahl was inspired to create Node.js after seeing a file upload on. The browser did not know how much of the file had been uploaded and had to query the Web server. Dahl desired an easier way. Dahl criticized the limited possibilities of the most popular web server in 2009,, to handle a lot of concurrent connections (up to 10,000 and more) and the most common way of creating code (sequential programming), when code either blocked the entire process or implied multiple execution stacks in the case of simultaneous connections.

Dahl demonstrated the project at the inaugural European JSConf on November 8, 2009. Node.js combined 's V8 JavaScript engine, an, and a low-level. The project received a standing ovation. In January 2010, a was introduced for the Node.js environment called. The package manager makes it easier for programmers to publish and share source code of Node.js libraries and is designed to simplify installation, updating, and uninstallation of libraries. In June 2011, Microsoft and Joyent implemented a native version of Node.js.

The first Node.js build supporting Windows was released in July 2011. In January 2012, Dahl stepped aside, promoting coworker and npm creator Isaac Schlueter to manage the project. In January 2014, Schlueter announced that Timothy J. Fontaine would lead the project.

In December 2014, Fedor Indutny started io.js, a of Node.js. Due to the internal conflict over Joyent's governance, io.js was created as an alternative with a separate technical committee.

Unlike Node.js, the authors planned to keep io.js up-to-date with the latest releases of the JavaScript engine. In February 2015, the intent to form a neutral Node.js Foundation was announced. By June 2015, the Node.js and io.js communities voted to work together under the Node.js Foundation. In September 2015, Node.js v0.12 and io.js v3.3 were merged back together into Node v4.0. This brought V8 features into Node.js, and a long-term support release cycle.

As of 2016, the io.js website recommends that developers switch back to Node.js and that no further releases of io.js are planned due to the merger. Overview [ ] Node.js allows the creation of and networking tools using and a collection of 'modules' that handle various core functionality. Modules are provided for I/O, networking (,,,, or ), data (buffers), functions,, and other core functions. Node.js's modules use an API designed to reduce the complexity of writing server applications. Node.js applications can run on,,,, and servers. Alternatively, they can be written with (a JavaScript alternative), or ( forms of JavaScript), or any other language that.

Node.js is primarily used to build network programs such as Web servers. The biggest difference between Node.js and is that most functions in PHP until completion (commands execute only after previous commands have completed), while functions in Node.js are designed to be (commands execute or even in, and use to signal completion or failure). Platform architecture [ ] Node.js brings to, enabling development of fast web servers in JavaScript. Developers can create highly scalable servers without using, by using a simplified model of that uses callbacks to signal the completion of a task. Node.js connects the ease of a scripting language (JavaScript) with the power of Unix network programming.

Node.js was built on the since it was open-sourced under the, extremely fast, and proficient with internet fundamentals such as,,. Also, was a well-known language, making Node.js immediately accessible to the entire. Industry support [ ] There are thousands of open-source libraries for Node.js, most of them hosted on the website. The Node.js developer community has two main mailing lists and the channel #node.js on. There are multiple developer conferences and events that support the Node.js community including, and as well as a number of regional events.

The open-source community has developed to accelerate the development of applications. Such frameworks include Connect,,, Koa.js, Hapi.js,,, Derby, and many others. Modern desktop provide editing and debugging features specifically for Node.js applications. Such IDEs include,,, (with Node.js Tools for Visual Studio, or with Node definitions, ), Enide Studio (-based), and. Certain online web-based IDEs also support Node.js, such as,,,, and the visual flow editor in. This section may be too for most readers to understand. Please to, without removing the technical details.

The may contain suggestions. (August 2015) () Node.js is a Javascript runtime environment that processes incoming requests in a loop, called the.

Threading [ ] Node.js operates on a, using calls, allowing it to support tens of thousands of concurrent connections without incurring the cost of thread. The design of sharing a single thread among all the requests that use the is intended for building highly concurrent applications, where any function performing I/O must use a. In order to accommodate the single-threaded event loop, Node.js utilizes the library that, in turn, uses a fixed-sized thread pool that is responsible for some of the non-blocking asynchronous I/O operations. A downside of this single-threaded approach is that Node.js doesn't allow by increasing the number of of the machine it is running on without using an additional module, such as cluster, StrongLoop Process Manager, or pm2.

However, developers can increase the default number of threads in the libuv thread pool; these threads are likely to be distributed across multiple cores by the server operating system. Execution of parallel tasks in Node.js is handled by a thread pool. The main thread call functions post tasks to the shared task queue that threads in the thread pool pull and execute. Inherently non-blocking system functions such as networking translates to kernel-side non-blocking sockets, while inherently blocking system functions such as file I/O run in a blocking way on its own thread. When a thread in the thread pool completes a task, it informs the main thread of this, which in turn, wakes up and execute the registered callback. Since callbacks are handled in serial on the main thread, long lasting computations and other CPU-bound tasks will freeze the entire event-loop until completion.

[ ] V8 [ ] is the JavaScript execution engine built for and open-sourced by Google in 2008. Written in, V8 compiles JavaScript source code to native instead of interpreting it in real time. A Tutor For The Renaissance Lute Pdf Reader. Node.js uses to handle asynchronous events.

Libuv is an abstraction layer for network and file system functionality on both Windows and -based systems such as Linux, macOS, OSS on NonStop, and Unix. The core functionality of Node.js resides in a JavaScript library. The Node.js bindings, written in C++, connect these technologies to each other and to the operating system.

Package management [ ] is the pre-installed package manager for the Node.js server platform. It is used to install Node.js programs from the npm registry, organizing the installation and management of third-party Node.js programs. Npm is not to be confused with the require() statement. It is not used to load code; instead, it is used to install code and manage code dependencies from the command line. The packages found in the npm registry can range from simple helper libraries such as to task runners such as. Unified API [ ] Node.js can be combined with a browser, a database supporting JSON data (such as,, or ) and for a unified JavaScript development stack. With the adaptation of what were essentially server-side development patterns such as,,, etc., Node.js allows the of the same model and service interface between client-side and server-side.

Event loop [ ] Node.js registers itself with the operating system in order to be notified when a connection is made, and the operating system will issue a callback. Within the Node.js runtime, each connection is a small.

Traditionally, relatively heavyweight processes or threads handled each connection. Node.js uses an event loop for scalability, instead of processes or threads. In contrast to other event-driven servers, Node.js's event loop does not need to be called explicitly. Instead callbacks are defined, and the server automatically enters the event loop at the end of the callback definition. Node.js exits the event loop when there are no further callbacks to be performed. Project governance [ ] In 2015, various branches of the greater Node.js community began working under the vendor-neutral Node.js Foundation.

The stated purpose of the organization 'is to enable widespread adoption and help accelerate development of Node.js and other related modules through an open governance model that encourages participation, technical contribution, and a framework for long-term stewardship by an ecosystem invested in Node.js' success.' The Node.js Foundation Technical Steering Committee (TSC) is the technical governing body of the Node.js Foundation. The TSC is responsible for the core Node.js repo as well as dependent and adjacent projects. Generally the TSC delegates administration of these projects to working groups or committees. The LTS group that manages long term supported releases is one such group. Other current groups include: Website, Streams, Build, Diagnostics, i18n, Evangelism, Docker, Addon API, Benchmarking, Post-mortem, Intl, Documentation, and Testing.

In August, 2017, a governance breakdown precipitated efforts to repair the resulting damage and to create a path to future stability of governance.
