JSTemplate - A pure Javascript templating engine for node.js

JSTemplate is a simple and pure-Javascript templating engine for node.js

Installing

npm install jstemplate

A basic template

<%
   var
        title = "Mr";
-%>
Hello <%= title %> <%= args.sir -%>

Processing a template

var
    JSTemplate = require('jstemplate'),
	jst = new JSTemplate({viewDir: 'views'});

jst.process("basic.jst",{sir:process.env.LOGNAME},function(err,output){
    if ( err )
        throw err;
    console.log(output);
});

Settings

The JSTemplate object supports the following settings:

• viewDir : The directory containing the templates (or views)

• statInterval : The interval of time (in ms) that a template file is stat()'ed and the modify time is watched to see if the template file was changed. Default to 5000

• useLayout : Defines if the layout.jst will be used to encapsulate the result of the processed template. Defaults to: true

The syntax

• <% CODE %> : Everything between <% and %> will be evaluated as javascript. Example: <% var x = 666; %>

• <%= VARIABLE|STATEMENT %> or <%? VARIABLE|STATEMENT %> : Prints the result of a variable or statement

• <& file.jst, {a:1,b:2} | p &> : Includes template file.jst and pass {a:1,b:2} as arguments (args variable); Optional | p flag can be passed to just pre-process the template so it can be included with jst.include()

Spaces and indentation

Optionally all tags can finish with a - (example <% args.somevar -%>) telling that the next return's should be discarded;

Accessible variables

These variable are accessible by the template code:

• args : The object containing the template arguments

• jst : The global JSTemplate object

API

The JSTemplate object exposes the following API:

• print(str) : Prints a string

• dump(obj) : Prints the dump of an object

• include(file,args) : Includes a template and call it with the specified arguments

• next() : Calls the next template on the execution stack (ninjas only)
