Nodejs Script Template
A basic script that offers the possibility to writing JS code in your HTML template.
Install
npm install script-tmpl --save
Example
template.html
<!DOCTYPE html>
<html>
<body>
<!NJ>="Hello World"<!NJ>
<!NJ>="IP Address:"+tmpl_data.ip<!NJ>
<!NJ>for(a=0;a<=10;a++) {<!NJ>
<span>For loop <!NJ>=a<!NJ></span>
<!NJ>}<!NJ>
<h1><!NJ>="Vive la France"<!NJ></h1>
<h1><!NJ>="1+1=" + (1+1)<!NJ></h1>
</body>
</html>
nodejs code:
const fs = require('fs');
const script_tmpl = require('script-tmpl');
var template_data = {'ip' : '127.0.0.1'};
fs.readFile("template.html", "utf8", function(err, data) {
script_tmpl.render(data, template_data, function(error, html) {
if(error) {
console.log(error);
} else {
console.log(html);
}
});
});
HTTP server:
var http = require('http');
const fs = require('fs');
const script_tmpl = require('script-tmpl');
http.createServer(function (req, res) {
var template_data = {'ip' : req.connection.remoteAddress};
fs.readFile("template.html", "utf8", function(err, data) {
script_tmpl.render(data, template_data, function(error, html) {
if(error) {
res.write(error);
res.end();
} else {
res.write(html);
res.end();
}
});
});
}).listen(8080);
Result:
<!DOCTYPE html>
<html>
<body>
Hello World
<span>For loop 0</span>
<span>For loop 1</span>
<span>For loop 2</span>
<span>For loop 3</span>
<span>For loop 4</span>
