 "desc": "<code>node [options] [V8 options] [script.js | -e \"script\" | - ] [arguments]</code>\nPlease see the <a href=\"cli.html#cli_command_line_options\">Command Line Options</a> document for information about\ndifferent options and ways to run scripts with Node.js.\n<h2>Example</h2>\nAn example of a <a href=\"http.html\">web server</a> written with Node.js which responds with\n<code>'Hello, World!'</code>:\nCommands displayed in this document are shown starting with <code>$</code> or <code>></code>\nto replicate how they would appear in a user's terminal.\nDo not include the <code>$</code> and <code>></code> characters. They are there to\nindicate the start of each command.\nThere are many tutorials and examples that follow this\nconvention: <code>$</code> or <code>></code> for commands run as a regular user, and <code>#</code>\nfor commands that should be executed as an administrator.\nLines that don’t start with <code>$</code> or <code>></code> character are typically showing\nthe output of the previous command.\nFirstly, make sure to have downloaded and installed Node.js.\nSee <a href=\"https://nodejs.org/en/download/package-manager/\">this guide</a> for further install information.\nNow, create an empty project folder called <code>projects</code>, then navigate into it.\nThe project folder can be named based on the user's current project title, but\nthis example will use <code>projects</code> as the project folder.\nLinux and Mac:\n<pre><code class=\"language-console\">$ mkdir ~/projects\n$ cd ~/projects\n</code></pre>\nWindows CMD:\n<pre><code class=\"language-console\">> mkdir %USERPROFILE%\\projects\n> cd %USERPROFILE%\\projects\n</code></pre>\nWindows PowerShell:\n<pre><code class=\"language-console\">> mkdir $env:USERPROFILE\\projects\n> cd $env:USERPROFILE\\projects\n</code></pre>\nNext, create a new source file in the <code>projects</code>\nfolder and call it <code>hello-world.js</code>.\nIn Node.js it is considered good style to use\nhyphens (<code>-</code>) or underscores (<code>_</code>) to separate\nmultiple words in filenames.\nOpen <code>hello-world.js</code> in any preferred text editor and\npaste in the following content:\n<pre><code class=\"language-js\">const http = require('http');\n\nconst hostname = '127.0.0.1';\nconst port = 3000;\n\nconst server = http.createServer((req, res) => {\n res.statusCode = 200;\n res.setHeader('Content-Type', 'text/plain');\n res.end('Hello, World!\\n');\n});\n\nserver.listen(port, hostname, () => {\n console.log(`Server running at http://${hostname}:${port}/`);\n});\n</code></pre>\nSave the file, go back to the terminal window enter the following command:\n<pre><code class=\"language-console\">$ node hello-world.js\n</code></pre>\nAn output like this should appear in the terminal to indicate Node.js\nserver is running:\n<pre><code class=\"language-console\">Server running at http://127.0.0.1:3000/\n</code></pre>\nNow, open any preferred web browser and visit <code>http://127.0.0.1:3000</code>.\nIf the browser displays the string <code>Hello, World!</code>, that indicates\nthe server is working.\nMany of the examples in the documentation can be run similarly."
