Advanced tools
Render template without any engine, pure JavaScript,easy to use, works with any file format including HTML, include files inside files, can be used with any framework and raw node.js
Render dynamic data to your template without any engine. A pure javascript module without any dependency and further installation.
It works using simple javascript function, high speedy and easy to use. works with any file format including HTML. you can also include another files in your file using include()
$ npm install templatesjs
for examples below we will be rendering dynamic data to a HTML page
in our html page we must use a tag to call data , a templatesjs tag looks like <%keyword%> note: you can change the delimiter that defines the tag (%)
examle HTML(index.html)
<!DOCTYPE HTML>
<html>
<head>
<title>TemplatesJS Demonstration</title>
</head>
<body>
HELLO <%user %>
</body>
</html>
here we will replace the <%user%> tag with John Doe;
in node.js file
var templatesjs = require('templatesjs');
fs.readFile("./index.html", function(err,data){
if(err) through err
/*you must set data once for each file, templatesjs works
with the given data, not with the actual file;*/
templatesjs.set(data);
var output = templatesjs.render("user", "John Doe");
res.write(output);
res.end();
});
this will print "HELLO John Doe" on the browser instead of hello <%user%>
we can also render array or object value as
<body>
HELLO <%user.name%>
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profile = {name:"John Doe",age:"18"};
var output = templatesjs.render("user", profile);
this will print "HELLO John Doe"
for array:
<body>
HELLO <%user[0]%>
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profile =["John Doe", "18"];
var output = templatesjs.render("user", profile);
this will print "HELLO John Doe"
or all values of an array :
<body>
HELLO <%user[]%>
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profile =["John Doe", "18"];
var output = templatesjs.render("user", profile);
this will print "HELLO John Doe18"
all array values starting from an index to another one
<body>
HELLO <%user[2,5]%>
<!--
**in the bracket the first number indicates the index
**from where the values should start and the
** second one indicates the index of stopping point
-->
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profile =["John", "Doe", "18", "hello", "world", "JS"];
var output = templatesjs.render("user", profile);
this will print "18helloworldJS"
suppose that we want a for each loop through our array values using templatesjs it can be done like
<body>
<%user[] {<a href="user/*">*</a>}%>
<!--
**specify the format in curly braces
** all "*" sign will be replaced by the actual
**value with the format specified around it
-->
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profiles =["John", "Doe"]
var output = templatesjs.render("user", profiles)
output : <a href="user/John">John</a> <a href="user/Doe">Doe</a>
for a loop through specified indexes of an array in specified format
<body>
<%user[2,4] {<a href="user/*">*</a>}%>
<!--
**specify the format in curly braces
** all "*" sign will be replaced by the actual
**value with the format specified around it
-->
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profiles =["John", "Doe", "foo", "bar", "example"]
var output = templatesjs.render("user", profiles)
output : <a href="user/foo">foo</a> <a href="user/bar">bar</a> <a href="user/example">ecample</a>
or specify format for only one array index if you want
<body>
<%user[2] {<a href="user/*">*</a>}%>
<!--
**specify the format in curly braces
** all "*" sign will be replaced by the actual
**value with the format specified around it
-->
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var profiles =["John", "Doe", "foo", "bar", "example"]
var output = templatesjs.render("user", profiles)
output : <a href="user/foo">foo</a>
specify output to be UPPERCASE or Capitalized or lowercase
you can specify whether the output will be in UPPERCASE, lowercase, Capitalized using a third optional "case" param
in the templatesjs.render() function
the case param supports three values "CASE", "Case", or "case"
"CASE" : for UPPERCASE output;"Case" : for Capitalized output"case" : for lowercase output <body>
UPPERCASE: <%uUser%>;
Capitalized: <%cUser%>;
lowercase: <%lUser%>;
</body>
in node.js file
var data = fs.readFileSync("./index.html");
templatesjs.set(data);
var output = templatesjs.render("uUser", "john", "CASE")
// "CASE" for UPPERCASE output
output = templatesjs.render("cUser", "doE", "Case")
// "Case" for Capitalized output
output = templatesjs.render("user", "SMith", "CASE")
// "case" for lowercase output
output : UPPERCASE: JOHN ;
Capitalized: Doe;
lowercase: smith;
templatesjs also has an include feature which can be used
to include file or template parts just use the <%include%> tag in your file
<body>
<%include header.html%>
<h3>Header is above</h3>
<h1>content goes here : </h1>
<%include posts/content.html%>
// the file is in ./post/ directory you can also
//use templatesjs.dir variable to set default
<h2>footer is below</h2>
<%include footer.html%>
</body>
no need to render anything in the node.js file, the files will be rendered
automatixally when you set data using templatesjs.set() function;
set default directory:
before you set data for templatesjs using the templatesjs.set() function you can set the default directory where templatesjs will
look for files it needs to include ;
suppose that we have all our html files in the "public" directory
in node.js file
var templatesjs = require('templatesjs');
templatesjs.dir = "./public/" // this is just a variable ;
templatesjs.set("/*you data goes here*/");
Don't like to use the "%" sign to define tags in html page you can change them :D :D :D use the templatesjs.delim() function
in node.js file
var templatesjs = require('templatesjs');
templatesjs.delim("$")
// you can use any sign like ["!@#$%^&*"] or
//any combination like "#@" or "%$" or "*&" or "*!"
are function names too long? there are shorthands availabe :D :D :D
functions can also be used as :
set() : s()
set() : setData()
set() : sd()
set() : setdata()
render() : ren()
render() : r()
render() : rn
delim() : delimier()
delim() : del(
delim() : d()
just have a look through the following code snippet:
<!--[index.html]-->
<body>
Welcome <span id="username"></span>
your Email <span id="email"></span>
your report : <%include report.txt%>
<script type="text/javascript">
var user = <%user%>;
for( x in user){
document.body.innerHTML+=x;
}
var profile = <%profile%>;
document.getElementById("username").innerHTML = profile.name;
document.getElementById("email").innerHTML = profile.email;
</script>
</body>
in node.js file
//[index.js]
var templatesjs = require('templatesjs');
var fs = require('fs');
var http = require('http');
http.crateServer(function(req,res){
fs.readFile("./public/index.html", function(err,data){
if(err) throw err;
templatesjs.dir = "./public/"
templatesjs.set(data)
var users=["John", "Doe", "Smith"];
var output = templatesjs.ren("user",users);
var profile = {name:"John Doe", email:"JohnDoe@smith.com"}
output = templatesjs.ren("profile", profile);
res.write(output);
res.end()
});
}).listen(8080);
