doT

Created in search of the fastest and concise JavaScript templating function with emphasis on performance under V8 and nodejs. It shows great performance for both nodejs and browsers.

doT.js is fast, small and has no dependencies.

Features

custom delimiters
runtime evaluation
runtime interpolation
compile-time evaluation
partials support
conditionals support
array iterators
encoding
control whitespace - strip or preserve
streaming friendly
use it as logic-less or with logic, it is up to you

Changelog

New in version 2.0.0

{{! }} renders falsy values with the exception of undefined

Breaking change. The falsy values 0, false, null, NaN and an empty string, but not undefined are stringified to their string values. For example, <p>{{! NaN }}</p> is now rendered as <p>NaN</p>. However, <p>{{! undefined }}</p> is still rendered as <p></p>.

In previous versions, an empty string was returned for any falsy value.

If you need {{! value }} to produce an empty string where value is falsy, write {{! value || '' }} or {{! value || undefined }}.

New in version 1.0.0

Added parameters support in partials

{{##def.macro:param:
	<div>{{=param.foo}}</div>
#}}

{{#def.macro:myvariable}}

Node module now supports auto-compilation of dot templates from specified path

var dots = require("dot").process({ path: "./views"});

This will compile .def, .dot, .jst files found under the specified path. Details

• It ignores sub-directories.
• Template files can have multiple extensions at the same time.
• Files with .def extension can be included in other files via {{#def.name}}
• Files with .dot extension are compiled into functions with the same name and can be accessed as renderer.filename
• Files with .jst extension are compiled into .js files. Produced .js file can be loaded as a commonJS, AMD module, or just installed into a global variable (default is set to window.render)
• All inline defines defined in the .jst file are compiled into separate functions and are available via _render.filename.definename

Basic usage:

       var dots = require("dot").process({path: "./views"});
       dots.mytemplate({foo:"hello world"});

The above snippet will: * Compile all templates in views folder (.dot, .def, .jst) * Place .js files compiled from .jst templates into the same folder These files can be used with require, i.e. require("./views/mytemplate") * Return an object with functions compiled from .dot templates as its properties * Render mytemplate template

CLI tool to compile dot templates into js files

./bin/dot-packer -s examples/views -d out/views

Example for express

Many people are using doT with express. I added an example of the best way of doing it examples/express:

Notes

doU.js is here only so that legacy external tests do not break. Use doT.js.
doT.js with doT.templateSettings.append=false provides the same performance as doU.js.
