I've written a software using node. Like telling via client to print something out on a printer which is connected per usb to the node.

I also wondered if I can execute an exe by node. I've searched enough to justify this question. I execute a bat file in the root of my server. There is a command in windows, called print. Those printers have a function, that cuts the paper. To add this function to the print, you have to add the special hexcode to the end of the file. That should be appliable on ever TM printer.

NodeJS is important because these client applications are just a surface for users to see and interact with. In addition to this, they need to talk to some service on the server or in the cloud for the storage of data, sending emails or pushing notifications. This is where NodeJS comes into the picture which allows users to create server-based applications in JavaScript and produce real time back-end services that can be used to power up client applications.

Before moving on the development phase, let us first see how to install NodeJS on our Linux based desktops. There are actually multiple ways to install NodeJS on a Linux based computer. We, however, will only be looking at two methods of installing NodeJS. A huge benefit of using this is that there are no permission issues for using NodeJS.

To do this, simply run the following command that will install the most recent version of NodeJS:. You can also install any specific version of NodeJS that you want to install. Once installed, you can check your NodeJS and npm installed versions by running the following commands:. In this method, we also have to install npm, the ecosystem of NodeJS libraries. This can be done by inputting the following command into the terminal:.

The following is the complete code:. In Node JS, there are some built in modules available. These are functions that have already been defined in NodeJS and provide certain functionality in our applications. These modules can be imported using the require keyword. Over here, we use a method of the HTTP module called createServer which, as the name says, creates a server instance.

In this, we pass a function through here which takes up two parameters — a request object and a response object. Now whenever a request is made to our server, this function will be called. The response object comes loaded with details about the request that has been made and the response object is something that we can use to send a response back to the client. Over here, response. This is how things can be printed on the browser.

In this case, this will allow us to print Hello World on the browser. The response. The server. It is important to note that any port that is available can be used here. The last line console. In this case, we are printing Server Running so that we know the server has started.

Now that we have our code written and understand what is happening in it, let us now run it and test whether it is working or not. To do this, open the directory, where you have saved your file containing the above NodeJS code and along with this, also open the terminal.

In order to run a NodeJS file, simply type in the following command in the terminal:. See below:. Now our server seems to be running. Let us now check to see if our response has been sent to the client.This article was written for an older version of node.

More up-to-date information may be available elsewhere. In programming literature it has become the standard to create a hello world program as the first example. This article will go through a few simple hello world type examples with everything from simple terminal output to an http server that uses an external framework for some semantic sugar. Then we'll shift gears and go through a real example that teaches enough to get you up on your feet writing your own web application using node.

Here are four simple hello world examples. The comments in the code explain how the code works and the text around it explain what it does and how to test it.

You can run this by putting it in a file called "hello-console. I'd guess that while it's not the only use case for node. JS, most people are using it as a web application platform.

Node.js - Net Module

So the next example will be a simple HTTP server that responds to every request with the plain text message "Hello World". Node also makes an excellent TCP server, and here is an example that responds to all TCP connections with the message "Hello World" and then closes the connection.

Often you won't be using the node built-in libraries because they are designed to be very low level. This makes node quick, nimble, and easy to maintain, but is usually not enough to get started on a real world application.

My first node framework is node-router. In order to test this, you will need to install the node-router library. There are two ways to do this. See the node docs on modules for more details on how modules work.

You can install these however you please, but here is how I'd do it. The following code will clone the four libraries and install them into your local node library search path:.

That's it for now, this article was going to explain more, but it seems it got lost and fell through the cracks. Hopefully this will help you get started working with node. JS, it's a blast!. The purpose of the blog is to teach how to do various tasks in node.

Hello Console This example is about as plain as it can get.In my last article, I introduced the most basic Node. While Hello World programs are nice, Node.

Insert the following code into the file and save it. To start the server, type the command shown below. If everything works properly, you will see a message that the server is listening.

Building TCP & UDP Servers with Node JS

Note that the example server attempts to bind to port 80, the standard HTTP port. If this port is already in use, or is restricted on your machine, you will experience an error.

The next step is to connect to the server using a web browser. Launch your browser of choice, and direct it to either of the following links.

The first thing to notice is the call to require on line 1. While many modules must be downloaded, some modules, such as http are included with Node. Like most Node. This callback function is executed each time the server receives a new request. The callback function takes two arguments, request and response. Similarly, the response object is used to return data back to the client.

The callback function begins by calling the response.

This method sends an HTTP status code and a collection of response headers back to the client. The status code is used to indicate the result of the request. For example, everyone has encountered a error before, indicating that a page could not be found.

The example server returns the codewhich indicates success. Along with the status code, the server returns a number of HTTP headers which define the parameters of the response.

If you do not specify headers, Node. The example server specifies only the Content-Type header. This particular header defines the MIME type of the response. Next, the server executes several calls to response. These calls are used to write the HTML page.Our system is designed from the ground up to be as fast and efficient as possible.
