The
network of networks is constantly changing. After responsive adaptations of
online presences and increasingly interactive interfaces to the esteemed user
community, Cloud Computing and Big Data have shaped the turnaround of recent
times.
In
the meantime, companies have long faced new challenges, such as the
"Internet of Things" (IoT, "Internet of Things") or
embedded systems in various household appliances, home automation,
transportation and entertainment electronics. But not only the economic resources
are affected, often a rethinking of the IT infrastructure is also necessary.
Node.js
A
promising approach is Node.js - a JavaScript-based platform for network
applications. The special thing about this is that it acts on the server side
and is based on the high-performance V8 runtime environment. Originally
developed for the increasingly popular browser project "Chrome", it
offers a resource-conserving architecture, which, unlike thread-based (blocking
I / O model) structures, reacts event-controlled (non-blocking I / O model)
sparingly. This behavior is an ideal basis for processing many concurrent,
asynchronous connections. Thus, the platform is predestined for data-intensive
use as a web server or for bidirectional web socket connections. Node.js also allows
other network applications to be optimally implemented.
The core: V8-Power
V8
was developed by Google in C ++ based on the ECMAScript specification
"ECMA-262" and supports the most common operating systems as well as
ARM architectures. The engine can be used either completely independently or as
an embedded component of a C ++ application. V8 is translated into machine code
at runtime via a JIT compiler. The result is provided as a snapshot for later
instances of the environment and offers clear performance advantages against
the pure use of a JavaScript interpreter. Often only the currently required
program components are compiled.
Threads v. Events
Conventional
server structures typically work thread-based. This means that incoming
requests are processed sequentially. The subsequent queries are only served as
soon as the respective predecessor has been supplied with his request. In the
case of an event-controlled approach, the requests are processed in a parallel
manner, there is no thread queue and subsequent requests are not blocked. In
this way, a "deadlock" is also prevented as a worst case. This is one
of the most significant advantages of Node.js., especially for many
data-intensive queries on highly frequented web servers.
Node Package Manager
The
"Node Package Manager" provides a variety of ready-to-use packages -
so-called modules - for Node.js. These can be easily installed via the command
line. The Node.js application radius can often be expanded many times over
these modules. Among other things, "CoffeeScript" and
"less" are also available as modules for the download.
CLI
The
"Command Line Interface" (CLI, the command line) is one of the main
input and output interfaces, in addition to the browser window for displaying
the web applications running on the Node.js web server. Here, for example,
status messages or user inputs are expected.
Who can use Node.js?
A
reasonable minimum requirement for the successful use of Node.js consists of a
(virtual) server system with root privileges, such as a Virtual Server.
Finally, a console is sometimes required to receive system feedback or to
install an npm package.
