Installation
$ npm install templatesjs
Usage
How to render string
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%>
How to render value of object
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"
How to render specific index value of an array
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"
How to render all values looping through the whole array
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"
How to render all values looping through some specific index of array
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"
How to specify format of output
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>}%>
</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>}%>
</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 case
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;
Include another file inside a file or data
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 for files
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*/");
Change the delimiter sign
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 "*!"
Shorthands for functions
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()
Demonstration with javascript on client side
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);
