A fast and pure NODE.js server-side module, and simple tool for making dynamic and interactive Web pages.
JHS module is just pure javascript code, processed on a NODE.js web server by a JHS interpreter implemented as a NODE.js module. On a web server, the result of the interpreted and executed JHS code β which may be any type of data, such as generated HTML or binary image data β would form the whole or part of an HTTP response.

The simplest way of using this middleware module involves two parts:
Firstly, write a webpage file with your favorite text editor, and name it with extension .jhs.
Save it to your web server root directory (or any other folder under the root). Use code
delimiters <?jhs and ?> to insert javascript code into de html code (this code will be
executed in the server side, not in the client side). As you already know, code
delimiters <script> </script> are html tags where you can insert javascript code that
will be executed in the client side, but JHS delimiters are not HTML tags). There is a JHS
echo function which is similar to the PHP echo function. Here it is a simple 'HELLO WORLD'
page example, written with JHS, you may call it hello-world.jhs:
<?jhs
var str = 'Hello world!';
var date = new Date();
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div style="text-align:center;">
<h1><?jhs echo(str) ?></h1>
<h2>Today is:</h2> <h3><?jhs echo(date.toString()) ?></h3>
</div>
</body>
</html>Secondly, in your NODE.js server script, the JHS module must be required, instantiated and called, like any other middleware engine:
...
const JHS = require('node-jhs').instance,
options = {root:"./wwwroot"},
parse_options = {},
file = options.root+'\\hello-world.jhs',
notfilepath = false,
execJHS = new JHS(options);
...
/* Call execJHS.parseFile async function, in your server request event listener */
server.on('request', function(request, response){
...
/* when a request for the 'hello-world.jhs' file is received,
you use the middleware JHS engine for the response
*/
execJHS.parseFile(file, notfilepath, parse_options, function(jhsResult, err){
response.end(jhsResult);
});
...
});You can use JHS module in production, but please use common sense when doing anything related to finances! I take no responsibility for your implementation decisions. If you find a security issue, please email me, justo.tapiador@gmail.com.
