# 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.
[](https://travis-ci.org/olado/doT)
[](https://www.npmjs.com/package/dot)
[](https://coveralls.io/github/olado/doT?branch=master)
## 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
## Docs, live playground and samples
http://olado.github.com/doT (todo: update docs with new features added in version 1.0.0)
## 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:
[doT with express](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.
